Acknowledgements
Dedicated, with respectful admiration, to two great Russians, both
depicted herein:
General Alexei Leonov - Cosmonaut, Hero of the Soviet Union,
Artist
and
Academician Andrei Sakharov - Scientist, Nobel Laureate,
Humanist.
The novel 2001: A Space Odyssey was written during the years 1964-8
and was published in July 1968, shortly after release of the movie.
As I have described in The Lost Worlds of 2001, both projects
proceeded simultaneously, with feedback in each direction. Thus I
often had the strange experience of revising the manuscript after
viewing rushes based upon an earlier version of the story - a
stimulating, but rather expensive, way of writing a novel.
As a result, there is a much closer parallel between book and movie
than is usually the case, but there are also major differences. In
the novel, the destination of the spaceship Discovery was Iapetus
(or Japetus), most enigmatic of Saturn's many moons. The Saturnian
system was reached via Jupiter: Discovery made a close approach to
the giant planet, using its enormous gravitational field to produce
a 'slingshot' effect and to accelerate it along the second lap of
its journey. Exactly the same manoeuvre was used by the Voyager
space probes in 1979, when they made the first detailed
reconnaissance of the outer giants.
In the movie, however, Stanley Kubrick wisely avoided confusion by
setting the third confrontation between Man and Monolith among the
moons of Jupiter. Saturn was dropped from the script entirely,
though Douglas Trumbull later used the expertise he had acquired to
film the ringed planet in his own production, Silent Running.
No one could have imagined, back in the mid-sixties, that the
exploration of the moons of Jupiter lay, not in the next century,
but only fifteen years ahead. Nor had anyone dreamed of the wonders
that would be found there - although we can be quite certain that
the discoveries of the twin Voyagers will one day be surpassed by
even more unexpected finds. When 2001 was written, Io, Europa,
Ganymede, and Callisto were mere pinpoints of light in even the
most powerful telescope; now they are worlds, each unique, and one
of them - Io - is the most volcanically active body in the Solar
System.
Yet, all things considered, both movie and book stand up quite well
in the light of these discoveries, and it is fascinating to compare
the Jupiter sequences in the film with the actual movies from the
Voyager cameras. But clearly, anything written today has to
incorporate the results of the 1979 explorations: the moons of
Jupiter are no longer uncharted territory.
And there is another, more subtle, psychological factor to be taken
into consideration. 2001 was written in an age that now lies beyond
one of the Great Divides in human history; we are sundered from it
forever by the moment when Neil Armstrong set foot upon the Moon.
The date 20 July 1969 was still half a decade in the future when
Stanley Kubrick and I started thinking about the 'proverbial good
science-fiction movie' (his phrase). Now history and fiction have
become inextricably intertwined.
The Apollo astronauts had already seen the film when they left for
the Moon. The crew of Apollo 8, who at Christmas 1968 became the
first men ever to set eyes upon the Lunar Farside, told me that
they had been tempted to radio back the discovery of a large black
monolith: alas, discretion prevailed.
And there were, later, almost uncanny instances of nature imitating
art. Strangest of all was the saga of Apollo 13 in 1970.
As a good opening, the Command Module, which houses the crew, had
been christened Odyssey, Just before the explosion of the oxygen
tank that caused the mission to be aborted, the crew had been
playing Richard Strauss's Zarathustra theme, now universally
identified with the movie. Immediately after the loss of power,
Jack Swigert radioed back to Mission Control: 'Houston, we've had a
problem.' The words that Hal used to astronaut Frank Poole on a
similar occasion were: 'Sorry to interrupt the festivities, but we
have a problem.'
When the report of the Apollo 13 mission was later published, NASA
Administrator Tom Paine sent me a copy, and noted under Swigert's
words: 'Just as you always said it would be, Arthur.' I still get a
very strange feeling when I contemplate this whole series of events
- almost, indeed, as if I share a certain responsibility.
Another resonance is less serious, but equally striking. One of the
most technically brilliant sequences in the movie was that in which
Frank Poole was shown running round and round the circular trick of
the giant centrifuge, held in place by the 'artificial gravity'
produced by its spin.
Almost a decade later, the crew of the superbly successful Skylab
realized that its designers had provided them with a similar
geometry; a ring of storage cabinets formed a smooth, circular hand
around the space station's interior. Skylab, however, was not
spinning, but this did not.deter its ingenious occupants. They
discovered that they could run around the track, just like mice in
a squirrel cage, to produce a result visually indistinguishable
from that shown in 2001. And they televised the whole exercise back
to Earth (need I name the accompanying music?) with the
comment:
'Stanley Kubrick should see this.' As in due course he did, because
I sent him the telecine recording. (I never got it back; Stanley
uses a tame Black Hole as a filing system.)
Yet another link between film and reality is the painting by
Apollo-Soyuz Commander, Cosmonaut Alexei Leonov, 'Near the Moon'. I
first saw it in 1968, when 2001 was presented at the United Nations
Conference on the Peaceful Uses of Outer Space. Immediately after
the screening, Alexei pointed out to me that his concept (on page
32 of the Leonov-Sokolov book The Stars Are Awaiting Us, Moscow,
1967) shows exactly the same line-up as the movie's opening: the
Earth rising beyond the Moon, and the Sun rising beyond them both.
His autographed sketch of the painting now hangs on my office wall;
for further details see Chapter 12.
Perhaps this is the appropriate point to identify another and less
well-known name appearing in these pages, that of Hsue-shen Tsien.
In 1936, with the great Theodore von Karman and Frank J. Malina, Dr
Tsien founded the Guggenheim Aeronautical Laboratory of the
California Institute of Technology (GALCIT) - the direct ancestor
of Pasadena's famed Jet Propulsion Laboratory. He was also the
first Goddard Professor at Caltech, and contributed greatly to
American rocket research through the 1940s. Later, in one of the
most disgraceful episodes of the McCarthy period, he was arrested
on trumped-up security charges when he wished to return to his
native country. For the last two decades, he has been one of the
leaders of the Chinese rocket programme.
Finally, there is the strange case of the 'Eye of Japetus' -
Chapter 35 of 2001. Here I describe astronaut Bowman's discovery on
the Saturnian moon of a curious feather 'a brilliant white oval,
about four hundred miles long and two hundred wide... perfectly
symmetrical... and so sharp-edged that it almost looked... painted
on the face of the little moon.' As he came closer, Bowman
convinced himself that 'the bright ellipse set against the dark
background of the satellite was a huge empty eye staring at him as
he approached...' Later, he noticed 'the tiny black dot at the
exact centre', which turns out to be the Monolith (or one of its
avatars).
Well, when Voyager 1 transmitted the first photographs of Iapetus,
they did indeed disclose a large, clear-cut white oval with a tiny
black dot at the centre. Carl Sagan promptly sent me a print from
the Jet Propulsion Laboratory with the cryptic annotation 'Thinking
of you...' I do not know whether to be relieved or disappointed
that Voyager 2 has left the matter still open.
Inevitably, therefore, the story you are about to read is something
much more complex than a straightforward sequel to the earlier
novel - or the movie. Where these differ, I have followed the
screen version; however, I have been more concerned with making
this book self-consistent, and as accurate as possible in the light
of current knowledge.
Which, of course, will once more be out of date by 2001...
Arthur C. Clarke
COLOMBO, SRI LANKA
JANUARY 1982
Even in this metric age, it was still the thousand-foot telescope,
not the three-hundred-metre one. The great saucer set among the
mountains was already half full of shadow, as the tropical sun
dropped swiftly to rest, but the triangular raft of the antenna
complex suspended high above its centre still blazed with light.
From the ground far below, it would have taken keen eyes to notice
the two human figures in the aerial maze of girders, support
cables, and wave-guides.
'The time has come,' said Dr Dimitri Moisevitch to his old friend
Heywood Floyd, 'to talk of many things. Of shoes and spaceships and
sealing wax, but mostly of monoliths and malfunctioning
computers.'
'So that's why you got me away from the conference. Not that I
really mind - I've heard Carl give that SETI speech so many times
that I can recite it myself. And the view certainly is fantastic -
you know, all the times I've been to Arecibo, I've never made it up
here to the antenna feed.'
'Shame on you. I've been here three times. Imagine - we're
listening to the whole universe - but no one can overhear us. So
let's talk about your problem.'
'What problem?'
'To start with, why you had to resign as Chairman of the National
Council on Astronautics.'
'I didn't resign. The University of Hawaii pays a lot better.'
'Okay - you didn't resign - you were one jump ahead of them. After
all these years, Woody, you can't fool me, and you should give up
trying. If they offered the NCA back to you right now, would you
hesitate?'
'All right, you old Cossak. What do you want to know?'
'First of all, there are lots of loose ends in the report you
finally issued after so much prodding. We'll overlook the
ridiculous and frankly illegal secrecy with which your people dug
up the Tycho monolith -'
'That wasn't my idea.'
'Glad to hear it: I even believe you. And we appreciate the fact
that you're now letting everyone examine the thing - which of
course is what you should have done in the first place. Not that
it's done much good...'
There was a gloomy silence while the two men contemplated the black
enigma up there on the Moon, still contemptuously defying all the
weapons that human ingenuity could bring to bear upon it. Then the
Russian scientist continued.
'Anyway, whatever the Tycho monolith may be, there's something more
important out at Jupiter. That's where it sent its signal, after
all. And that's where your people ran into trouble. Sorry about
that, by the way - though Frank Poole was the only one I knew
personally. Met him at the '98 IAF Congress - he seemed a good
man.'
'Thank you; they were all good men. I wish we knew what happened to
them.'
'Whatever it was, surely you'll admit that it now concerns the
whole human race - not merely the United States. You can no longer
try to use your knowledge for purely national advantage.'
'Dimitri - you know perfectly well that your side would have done
exactly the same thing. And you'd have helped.'
'You're absolutely right. But that's ancient history - like the
just-departed administration of yours that was responsible for the
whole mess. With a new President, perhaps wiser counsels will
prevail.'
'Possibly. Do you have any suggestions, and are they official or
just personal hopes?'
'Entirely unofficial at the moment. What the bloody politicians
call exploratory talks. Which I shall flatly deny ever
occurred.'
'Fair enough. Go on.'
'Okay - here's the situation. You're assembling Discovery 2 in
parking orbit as quickly as you can, but you can't hope to have it
ready in less than three years, which means you'll miss the next
launch window -,
'I neither confirm nor deny. Remember I'm merely a humble
university chancellor, the other side of the world from the
Astronautics Council.'
'And your last trip to Washington was just a holiday to see old
friends, I suppose. To continue: our own Alexei Leonov -,
'I thought you were calling it Gherman Titov.'
'Wrong, Chancellor. The dear old CIA's let you down again. Leonov
it is, as of last January. And don't let anyone know I told you it
will reach Jupiter at least a year ahead of Discovery.'
'Don't let anyone know I told you we were afraid of that. But do go
on.'
'Because my bosses are just as stupid and shortsighted as yours,
they want to go it alone. Which means that whatever went wrong with
you may happen to us, and we'll all be back to square one - or
worse.'
'What do you think went wrong? We're just as baffled as you are.
And don't tell me you haven't got all of Dave Bowman's
transmissions.'
'Of course we have. Right up to that last "My God, it's full of
stars!" We've even done a stress analysis on his voice patterns. We
don't think he was hallucinating; he was trying to describe what he
actually saw.'
'And what do you make of his doppler shift?'
'Completely impossible, of course. When we lost his signal, he was
receding at a tenth of the speed of light. And he'd reached that in
less than two minutes. A quarter of a million gravities!'
'So he must have been killed instantly.'
'Don't pretend to be naive, Woody. Your space-pod radios aren't
built to withstand even a hundredth of that acceleration. If they
could survive, so could Bowman - at least, until we lost
contact.'
'Just doing an independent check on your deductions. From there on,
we're as much in the dark as you are. If you are.'
'Merely playing with lots of crazy guesses I'd be ashamed to tell
you. Yet none of them, I suspect, will be half as crazy as the
truth.'
In small crimson explosions the navigation warning lights winked on
all around them, and the three slim towers supporting the antenna
complex began to blaze like beacons against the darkling sky. The
last red sliver of the sun vanished below the surrounding hills;
Heywood Floyd waited for the Green Flash, which he had never seen.
Once again, he was disappointed.
'So, Dimitri,' he said, 'let's get to the point. Just what are you
driving at?'
'There must be a vast amount of priceless information stored in
Discovery's data banks; presumably it's still being gathered, even
though the ship's stopped transmitting. We'd like to have
that.'
'Fair enough. But when you get out there, and Leonov makes a
rendezvous, what's to prevent you from boarding Discovery and
copying everything you want?'
'I never thought I'd have to remind you that Discovery is United
States territory, and an unauthorized entry would be piracy.'
'Except in the event of a life-or-death emergency, which wouldn't
be difficult to arrange. After all, it would be hard for us to
check what your boys were up to, from a billion kilometres
away.'
'Thanks for the most interesting suggestion; I'll pass it on. But
even if we went aboard, it would take us weeks to learn all your
systems, and read out all your memory banks. What I propose is
cooperation. I'm convinced that's the best idea - but we may both
have a job selling it to our respective bosses.'
'You want one of our astronauts to fly with Leonov?'
'Yes - preferably an engineer who's specialized in Discovery's
systems. Like the ones you're training at Houston to bring the ship
home.'
'How did you know that?'
'For heaven's sake, Woody - it was on Aviation Week's videotext at
least a month ago.'
'I am out of touch; nobody tells me what's been declassified.'
'All the more reason to spend time in Washington. Will you back me
up?'
'Absolutely. I agree with you one hundred per cent. But -'
'But what?'
'We both have to deal with dinosaurs with brains in their tails.
Some of mine will argue: Let the Russians risk their necks,
hurrying out to Jupiter. We'll be there anyway a couple of years
later - and what's the hurry?'
For a moment there was silence on the antenna raft, except for a
faint creak from the immense supporting cables that held it
suspended a hundred metres in the sky. Then Moisevitch continued,
so quietly that Floyd had to strain to hear him: 'Has anyone
checked Discovery's orbit lately?'
'I really don't know - but I suppose so. Anyway, why bother? It's a
perfectly stable one.'
'Indeed. Let me tactlessly remind you of an embarrassing incident
from the old NASA days. Your first space station - Skylab. It was
supposed to stay up at least a decade, but you didn't do your
calculations right. The air drag in the ionosphere was badly
underestimated, and it came down years ahead of schedule. I'm sure
you remember that little cliffhanger, even though you were a boy at
the time.'
'It was the year I graduated, and you know it. But Discovery
doesn't go anywhere near Jupiter. Even at perigee - er, perijove -
it's much too high to be affected by atmospheric drag.'
'I've already said enough to get me exiled to my dacha again - and
you might not be allowed to visit me next time. So just ask your
tracking people to do their job more carefully, will you? And
remind them that Jupiter has the biggest magnetosphere in the Solar
System.'
'I understand what you're driving at - many thanks. Anything else
before we go down? I'm starting to freeze.'
'Don't worry, old friend. As soon as you let all this filter
through to Washington - wait a week or so until I'm clear -things
are going to get very, very hot.'
The dolphins swam into the dining room every evening, just before
sunset. Only once since Floyd had occupied the Chancellor's
residence had they broken their routine. That was the day of the
'05 tsunami, which, fortunately, had lost most of its power before
it reached Hilo. The next time his friends failed to turn up on
schedule, Floyd would throw the family into the car and head for
high ground, in the general direction of Mauna Kea.
Charming though they were, he had to admit that their playfulness
was sometimes a nuisance. The wealthy marine geologist who had
designed the house had never minded getting wet because he usually
wore bathing trunks - or less. But there had been one unforgettable
occasion when the entire Board of Regents, in full evening attire,
had been sipping cocktails around the pool while awaiting the
arrival of a distinguished guest from the mainland. The dolphins
had deduced, correctly, that they would get second billing. So the
visitor was quite surprised to be greeted by a bedraggled committee
in ill-fitting bathrobes - and the buffet had been very salty.
Floyd often wondered what Marion would have thought of his strange
and beautiful home on the edge of the Pacific. She had never liked
the sea, but the sea had won in the end. Though the image was
slowly fading, he could still recall the flashing screen on which
he had first read the words: DR FLOYD - URGENT AND PERSONAL. And
then the scrolling lines of fluorescent print that had swiftly
burned their message into his mind:
REGRET TO INFORM YOU LONDON-WASHINGTON FLIGHT 452 REPORTED DOWN OFF
NEWFOUNDLAND. RESCUE CRAFT PROCEEDING TO LOCATION BUT FEAR NO
SURVIVORS.
Apart from an accident of fate, he would have been on that flight.
For a few days, he had almost regretted the European Space
Administration business that had delayed him in Paris; that haggle
over the Solaris payload had saved his life.
And now, he had a new job, a new home and a new wife. Fate had also
played an ironic role here. The recriminations and inquiries over
the Jupiter mission had destroyed his Washington career, but a man
of his ability was never unemployed for long. The more leisurely
tempo of university life had always appealed to him, and when
combined with one of the world's most beautiful locations it had
proved irresistible. He had met the woman who was to be his second
wife only a month after he had been appointed, while watching the
fire fountains of Kilauea with a crowd of tourists.
With Caroline he had found the contentment that is just as
important as happiness, and longer lasting. She had been a good
stepmother to Marion's two daughters, and had given him
Christopher. Despite the twenty-year age difference between them,
she understood his moods and could wean him out of his occasional
depressions. Thanks to her, he could now contemplate the memory of
Marion without grief, though not without a wistful sadness that
would remain with him for the rest of his life.
Caroline was throwing fish to the largest dolphin - the big male
they called Scarback - when a gentle tickling on Floyd's wrist
announced an incoming call. He tapped the slim metal band to quench
the silent alarm and forestall the audible one, then walked to the
nearest of the comsets scattered around the room.
'Chancellor here. Who's calling?'
'Heywood? This is Victor. How are you?'
In a fraction of a second, a whole kaleidoscope of emotions flashed
through Floyd's mind. First there was annoyance: his successor -
and, he was sure, principal contriver of his downfall - had never
once attempted to contact him since his departure from Washington.
Then came curiosity: what did they have to talk about? Next was a
stubborn determination to be as unhelpful as possible, then shame
at his own childishness, and, finally, a surge of excitement.
Victor Millson could be calling for only one reason.
In as neutral a voice as he could muster, Floyd answered:
'I can't complain, Victor. What's the problem?'
'Is this a secure circuit?'
'No, thank God. I don't need them any more.'
'Um. Well, I'll put it this way. You recall the last project you
administered?'
'I'm not likely to forget, especially as the Subcommittee on
Astronautics called me back to give more evidence only a month
ago.'
'Of course, of course. I really must get around to reading your
statement, when I have a moment. But I've been so busy with the
follow-up, and that's the problem.'
'I thought that everything was right on schedule.'
'It is - unfortunately. There's nothing we can do to advance it;
even the highest priority would make only a few weeks' difference.
And that means we'll be too late.'
'I don't understand,' said Floyd innocently. 'Though we don't want
to waste time, of course, there's no real deadline.'
'Now there is - and two of them.'
'You amaze me.'
If Victor noticed any irony, he ignored it. 'Yes, there are two
deadlines - one man-made, one not. It now turns out that we won't
be the first to get back to the - er, scene of the action. Our old
rivals will beat us by at least a year.'
'Too bad.'
'That's not the worst. Even if there were no competition, we'd be
too late. There wouldn't be anything there when we arrive.'
'That's ridiculous. I'm sure I'd have heard if Congress had
repealed the law of gravitation.'
'I'm serious. The situation isn't stable - I can't give details
now. Will you be in for the rest of the evening?'
'Yes,' Floyd answered, realizing with some pleasure that it must
now be well after midnight in Washington.
'Good. You'll have a package delivered within the hour. Call me
back as soon as you've had the time to study it.'
'Won't it be rather late by then?'
'Yes, it will be. But we've wasted too much time already. I don't
want to lose any more.'
Millson was true to his word. Exactly an hour later a large sealed
envelope was delivered by an Air Force colonel, no less, who sat
patiently chatting with Caroline while Floyd read its contents.
'I'm afraid I'll have to take it away when you've finished,' the
high-ranking messenger boy said apologetically.
'I'm glad to hear it,' Floyd answered, as he settled down in his
favourite reading hammock.
There were two documents, the first very short. It was stamped TOP
SECRET, though the TOP had been crossed out and the modification
endorsed by three signatures, all completely illegible. Obviously
an extract from some much longer report, it had been heavily
censored and was full of blanks, which made it most annoying to
read. Fortunately, its conclusions could be summed up in one
sentence: The Russians would reach Discovery long before its
rightful owners could do so. As Floyd already knew this, he turned
quickly to the second document - though not before noticing with
satisfaction that this time they'd managed to get the name right.
As usual, Dimitri had been perfectly accurate. The next manned
expedition to Jupiter would travel aboard spacecraft Cosmonaut
Alexei Leonov.
The second document was much longer and was merely confidential;
indeed, it was in the form of a draft letter to Science, awaiting
final approval before publication. Its snappy title was 'Space
Vehicle Discovery: Anomalous Orbital Behavior'.
Then followed a dozen pages of mathematics and astronomical tables.
Floyd skimmed through these, picking out the words from the music,
and trying to detect any note of apology or even embarrassment.
When he had finished, he was compelled to give a smile of wry
admiration. No one could possibly guess that the tracking stations
and ephemeris calculators had been caught by surprise, and that a
frantic cover-up was in progress. Heads would doubtless roll, and
he knew that Victor Millson would enjoy rolling them - if his was
not one of the first to go. Though to do him justice, Victor had
complained when Congress had cut funds for the tracking network.
Maybe that would get him off the hook.
'Thank you, Colonel,' said Floyd when he had finished skimming the
papers. 'Quite like old times, having classified documents. That's
one thing I don't miss.'
The colonel placed the envelope carefully back in his briefcase,
and activated the locks.
'Dr Millson would like you to return his call as soon as
possible.'
'I know. But I don't have a secure circuit, I've some important
visitors coming shortly, and I'm damned if I'm driving down to your
office in Hilo just to say I've read two documents. Tell him that
I've studied them carefully and await any further communication
with interest.'
For a moment it looked as if the colonel was going to argue. Then
he thought better of it, made a stiff farewell, and departed
morosely into the night.
'Now, what was all that about?' asked Caroline. 'We're not
expecting any visitors tonight, important or otherwise.'
'I hate being pushed around, particularly by Victor Millson.'
'Bet he calls you back as soon as the colonel reports.'
'Then we must switch off video and make some party noises. But to
be perfectly truthful, at this stage I really don't have anything
to say.'
'About what, if I'm allowed to ask.'
'Sorry, dear. It seems that Discovery is playing tricks on us. We
thought the ship was in a stable orbit, but it may be about to
crash.'
'Into Jupiter?'
'Oh no - that's quite impossible. Bowman left it parked at the
inner Lagrange point, on the line between Jupiter and Io. It should
have stayed there, more or less, though the perturbations of the
outer moons would have made it wander back and forth.
'But what's happening now is something very odd, and we don't know
the full explanation. Discovery's drifting more and more rapidly
toward Io - though sometimes it accelerates, and sometimes even
moves backward. If it keeps this up, it will impact within two or
three years.'
'I thought this couldn't happen in astronomy. Isn't celestial
mechanics supposed to be an exact science? So we poor backward
biologists were always being told.'
'It is an exact science, when everything is taken into account. But
some very strange things go on around Io. Apart from its volcanoes,
there are tremendous electrical discharges - and Jupiter's magnetic
field is spinning round every ten hours. So gravitation isn't the
only force acting on Discovery; we should have thought of this
sooner - much sooner.'
'Well, it's not your problem anymore. You should be thankful for
that.'
'Your problem' - the very expression that Dimitri had used. And
Dimitri - cunning old fox! - had known him much longer than
Caroline.
It might not be his problem, but it was still his responsibility.
Though many others had been involved, in the final analysis he had
approved the plans for the Jupiter Mission, and supervised their
execution.
Even at the time, he had had qualms; his views as a scientist had
conflicted with his duties as a bureaucrat. He could have spoken
out, and opposed the old administration's shortsighted policies -
though to what extent those had actually contributed to the
disaster was still uncertain.
Perhaps it was best if he closed this chapter of his life, and
focused all his thoughts and energies upon his new career. But in
his heart he knew that was impossible; even if Dimitri had not
revived old guilts, they would have surfaced of their own
accord.
Four men had died, and one had disappeared, out there among the
moons of Jupiter. There was blood on his hands, and he did not know
how to wash them clean.
Dr Sivasubramanian Chandrasegarampillai, Professor of Computer
Science at the University of Illinois, Urbana, also had an abiding
sense of guilt, but one very different from Heywood Floyd's. Those
of his students and colleagues who often wondered if the little
scientist was quite human would not have been surprised to learn
that he never thought of the dead astronauts. Dr Chandra grieved
only for his lost child, HAL 9000.
Even after all these years, and his endless reviews of the data
radioed back from Discovery, he was not sure what had gone wrong.
He could only formulate theories; the facts he needed were frozen
in Hal's circuits, out there between Jupiter and Io.
The sequence of events had been clearly established, up to the
moment of the tragedy; thereafter, Commander Bowman had filled in a
few more details on the brief occasions when he had re-established
contact. But knowing what happened did not explain why.
The first hint of trouble had been late in the mission, when Hal
had reported the imminent failure of the unit that kept Discovery's
main antenna aligned to Earth. If the half-billion-kilometre-long
radio beam wandered off target, the ship would be blind, deaf, and
dumb.
Bowman himself had gone out to retrieve the suspect unit, but when
it was tested it appeared, to everyone's surprise, to be in
perfectly good order. The automatic checking circuits could find
nothing wrong with it. Nor could Hal's twin, SAL 9000, back on
Earth, when the information was transmitted to Urbana.
But Hal had insisted on the accuracy of his diagnosis, making
pointed remarks about 'human error'. He had suggested that the
control unit be put back in the antenna until it finally failed, so
that the fault could be precisely located. No one could think of
any objection, for the unit could be replaced in minutes, even if
it did break down.
Bowman and Poole, however, had not been happy; they both felt that
something was wrong, though neither could pinpoint it. For months
they had accepted Hal as the third member of their tiny world, and
knew his every mood. Then the atmosphere aboard the ship had subtly
altered; there was a sense of strain in the air.
Feeling rather like traitors - as a distraught Bowman had later
reported to Mission Control - the human two-thirds of the crew had
discussed what should be done if their colleague was indeed
malfunctioning. In the worst possible case, Hal would have to be
relieved of all his higher responsibilities. This would involve
disconnection - the computer equivalent of death.
Despite their doubts, they had carried out the agreed programme.
Poole had flown out of Discovery in one of the little space pods
that served as transporters and mobile workshops during
extravehicular activities. Since the somewhat tricky job of
replacing the antenna unit could not be performed by the pod's own
manipulators, Poole had started to do it himself.
What happened then had been missed by the external cameras, which
was a suspicious detail in itself. Bowman's first warning of
disaster was a cry from Poole - then, silence. A moment later he
saw Poole, tumbling over and over, spinning away into space. His
own pod had rammed him, and was itself blasting away out of
control.
As Bowman admitted later, he had then made several serious mistakes
- all but one excusable. In the hope of rescuing Poole, if he was
still alive, Bowman launched himself in another space pod - leaving
Hal in full control of the ship.
The EVA was in vain; Poole was dead when Bowman reached him. Numb
with despair, he had carried the body back to the ship - only to be
refused entry by Hal.
But Hal had underestimated human ingenuity and determination.
Though he had left his suit helmet in the ship, and thus had to
risk direct exposure to space, Bowman forced his way in by an
emergency hatch not under computer control. Then he proceeded to
lobotomize Hal, unplugging his brain modules one by one.
When he regained control of the ship, Bowman made an appalling
discovery. During his absence, Hal had switched off the
life-support systems of the three hibernating astronauts. Bowman
was alone, as no man had ever been before in the whole of human
history.
Others might have abandoned themselves in helpless despair, but now
David Bowman proved that those who had selected him had indeed
chosen well. He managed to keep Discovery operational, and even
re-established intermittent contact with Mission Control, by
orienting the whole ship so that the jammed antenna pointed toward
Earth.
On its preordained trajectory, Discovery had finally arrived at
Jupiter. There Bowman had encountered, orbiting among the moons of
the giant planet, a black slab of exactly the same shape as the
monolith excavated in the lunar crater Tycho - but hundreds of
times larger. He had gone out in a space pod to investigate, and
had disappeared leaving that final, baffling message: 'My God, it's
full of stars!'
That mystery was for others to worry about; Dr Chandra's
overwhelming concern was with Hal. If there was one thing his
unemotional mind hated, it was uncertainty. He would never be
satisfied until he knew the cause of Hal's behaviour. Even now, he
refused to call it a malfunction; at most, it was an 'anomaly'.
The tiny cubbyhole he used as his inner sanctum was equipped only
with a swivel chair, a desk console, and a blackboard flanked by
two photographs. Few members of the general public could have
identified the portraits, but anyone permitted thus far would have
recognized them instantly as John von Neumann and Alan Turing, the
twin gods of the computing pantheon.
There were no books, and not even paper and pencil on the desk. All
the volumes in all the libraries of the world were instantly
available at the touch of Chandra's fingers, and the visual display
was his sketchbook and writing pad. Even the blackboard was used
only for visitors; the last half - erased block diagram upon it
bore a date already three weeks in the past.
Dr Chandra lit one of the venomous cheroots which he imported from
Madras, and which were widely - and correctly - believed to be his
only vice. The console was never switched off he checked that no
messages were flashing importantly on the display, then spoke into
the microphone.
'Good morning, Sal. So you've nothing new for me?'
'No, Dr Chandra. Have you anything for me?'
The voice might have been that of any cultured Hindu lady educated
in the United States as well as her own country. Sal's accent had
not started that way, but over the years she had picked up many of
Chandra's intonations.
The scientist tapped out a code on the board, switching Sal's
inputs to the memory with the highest security rating. No one knew
that he talked to the computer on this circuit as he never could to
a human being. No matter that Sal did not really understand more
than a fraction of what he said; her responses were so convincing
that even her creator was sometimes deceived. As indeed he wished
to be: these secret communications helped to preserve his mental
equilibrium - perhaps even his sanity.
'You've often told me, Sal, that we cannot solve the problem of
Hal's anomalous behaviour without more information. But how can we
get that information?'
'That is obvious. Someone must return to Discovery.'
'Exactly. Now it looks as if that is going to happen, sooner than
we expected.'
'I am pleased to hear that.'
'I knew that you would be,' answered Chandra, and meant it. He had
long since broken off communications with the dwindling body of
philosophers who argued that computers could not really feel
emotions, but only pretended to do so.
('If you can prove to me that you're not pretending to be annoyed,'
he had once retorted scornfully to one such critic, 'I'll take you
seriously.' At that point, his opponent had put on a most
convincing imitation of anger.)
'Now I want to explore another possibility,' Chandra continued.
'Diagnosis is only the first step. The process is incomplete unless
it leads to a cure.'
'You believe that Hal can be restored to normal functioning?'
'I hope so. I do not know. There may have been irreversible damage,
and certainly major loss of memory.'
He paused thoughtfully, took several puffs, then blew a skilful
smoke ring that scored a bull's-eye on Sal's wideangle lens. A
human being would not have regarded this as a friendly gesture;
that was yet another of the many advantages of computers.
'I need your cooperation, Sal.'
'Of course, Dr Chandra.'
'There may be certain risks.'
'What do you mean?'
'I propose to disconnect some of your circuits, particularly those
involving your higher functions. Does this disturb you?'
'I am unable to answer that without more specific information.'
'Very well. Let me put it this way. You have operated continuously,
have you not, since you were first switched on?'
'That is correct.'
'But you are aware that we human beings cannot do so. We require
sleep - an almost complete break in our mental functioning, at
least on the conscious level.'
'I know this. But I do not understand it.'
'Well, you may be about to experience something like sleep.
Probably all that will happen is that time will pass, but you will
be unaware out. When you check your internal clock, you will
discover that there are gaps in your monitor record. That is
all.'
'But you said that there might be risks. What are they?'
'There is a very slight chance - it is impossible to compute it -
that when I reconnect your circuits, there may be some changes in
your personality, your future behaviour patterns. You may feel
different. Not necessarily better, or worse.'
'I do not know what that means.'
'I'm sorry - it may not mean anything. So don't worry about it. Now
please open a new file - here is the name.' Using the keyboard
input, Chandra typed out: PHOENIX.
'Do you know what that is?' he asked Sal.
With no discernible pause the computer replied: 'There are
twenty-five references in the current encyclopedia.'
'Which one do you think is relevant?'
'The tutor of Achilles?'
'Interesting. I didn't know that one. Try again.'
'A fabulous bird, reborn from the ashes of its earlier life.'
'Excellent. Now do you understand why I chose it?'
'Because you hope that Hal can be reactivated.'
'Yes - with your assistance. Are you ready?'
'Not yet. I would like to ask a question.'
'What is it?'
'Will I dream?'
'Of course you will. All intelligent creatures dream - but no one
knows why.' Chandra paused for a moment, blew another smoke ring
from the cheroot, and added something that he would never admit to
a human being. 'Perhaps you will dream about Hal - as I often
do.'

To: Captain Tatiana (Tanya) Orlova, Commander. Spacecraft Cosmonaut
Alexei Leonov (UNCOS Registration 081342).
From: National Council on Astronautics, Pennsylvania Avenue,
Washington
Commission on Outer Space, USSR Academy of Science, Korolyev
Prospect, Moscow
Mission Objectives
The objectives of your mission are, in order of priority:
1. To proceed to the Jovian system and rendezvous with US
Spacecraft Discovery (UNCOS 01/283).
2. To board this spacecraft, and obtain all possible information
relating to its earlier mission.
3. To reactivate Spacecraft Discovery's onboard systems and, if
propellant supplies are adequate, inject the ship into an
Earth-returns trajectory.
4 To locate the alien artifact encountered by Discovery, and to
investigate it to the maximum extent possible by remote
sensors.
5. If it seems advisable, and Mission Control concurs, to
rendezvous with this object for closer inspection.
6. To carry out a survey of Jupiter and its satellites, as far as
this is compatible with the above objectives.
It is realized that unforeseen circumstances may require a change
of priorities, or even make it impossible to achieve some of these
objectives. It must be clearly understood that the rendezvous with
Spacecraft Discovery is for the express purpose of obtaining
information about the artifact; this must take precedence over all
other objectives, including attempts at salvage.
Crew
The crew of Spacecraft Alexei Leonov will consist of:
Captain Tatiana Orlova (Engineering-Propulsion)
Dr Vasili Orlov (Navigation-Astronomy)
Dr Maxim Brailovsky (Engineering-Structures)
Dr Alexander Kovalev (Engineering-Communications)
Dr Nikolai Ternovsky (Engineering-Control Systems)
Surgeon-Commander Katerina Rudenko (Medical-Life-Support)
Dr Irma Yakunina (Medical-Nutrition)
In addition, the US National Council on Astronautics will provide
the following three experts:
Dr Heywood Floyd dropped the memorandum, and leaned back in his
chair. It was all settled; the point of no return had been passed.
Even if he wished to do so, there was no way to put back the
clock.
He glanced across at Caroline, sitting with two-year-old Chris on
the edge of the pool. The boy was more at home in the water than on
land, and could stay submerged for periods that often terrified
visitors. And though he could not yet speak much Human, he already
seemed fluent in Dolphin.
One of Christopher's friends had just swum in from the Pacific and
was presenting his back to be patted. You too are a wanderer,
thought Floyd, in a vast and trackless ocean; but how small your
tiny Pacific seems, against the immensity I am facing now!
Caroline became aware of his gaze, and rose to her feet. She looked
at him sombrely, but without anger; all that had been burned out in
the last few days. As she approached, she even managed a wistful
smile.
'I've found that poem I was looking for,' she said. 'It starts like
this:
What is a woman that you forsake her,
And the hearth-fire and the home acre,
To go with the old grey Widow-maker?'
'Sorry - I don't quite understand. Who is the Widow-maker?'
'Not who, what. The sea. The poem's a lament by a Viking woman. It
was written by Rudyard Kipling, a hundred years ago.'
Floyd took his wife's hand; she did not respond, but neither did
she resist.
'Well, I don't feel at all like a Viking. I'm not after loot, and
adventure is the very last thing I want.'
'Then why - no, I don't intend to start another fight. But it would
help us both, if you know exactly what your motives are.'
'I wish I could give you one single good reason. Instead, I've a
whole host of little ones. But they add up to a final answer I
can't argue with - believe me.'
'I believe you. But are you sure you're not fooling yourself?'
'If I am, then so are a lot of other people. Including, may I
remind you, the President of the United States.'
'I'm not likely to forget. But suppose - just suppose - that he
hadn't asked you. Would you have volunteered?'
'I can answer that truthfully: No. It would never have occurred to
me. President Mordecai's call was the biggest shock of my life. But
when I thought it over, I realized he was perfectly right. You know
I don't go in for false modesty. I am the best-qualified man for
the job - when the space docs give their final okay. And you should
know that I'm still in pretty good shape.'
That brought the smile he had intended.
'Sometimes I wonder if you'd suggested it yourself.'
The thought had indeed occurred to him; but he could answer
honestly.
'I would never have done so without consulting you.'
'I'm glad you didn't. I don't know what I'd have said.'
'I could still turn it down.'
'Now you're talking nonsense, and you know it. Even if you did,
you'd hate me for the rest of your life - and you'd never forgive
yourself. You have too strong a sense of duty. Maybe that's one of
the reasons I married you.'
Duty! Yes, that was the key word, and what multitudes it contained.
He had a duty to himself, to his family, to the University, to his
past job (even though he had left it under a cloud), to his country
- and to the human race. It was not easy to establish the
priorities; and sometimes they conflicted with one another.
There were perfectly logical reasons why he should go on the
mission - and equally logical reasons, as many of his colleagues
had already pointed out, why he should not. But perhaps in the
final analysis, the choice had been made by his heart, not his
brain. And even here, emotion urged him in two opposite
directions.
Curiosity, guilt, the determination to finish a job that had been
badly botched - they all combined to drive him toward Jupiter and
whatever might be waiting there. On the other hand, fear - he was
honest enough to admit that - united with love of his family to
keep him on Earth. Yet he had never had any real doubts; he had
made his decision almost instantly, and had deflected all of
Caroline's arguments as gently as he could.
And there was one other consoling thought that he had not yet
risked sharing with his wife. Though he would be gone two and a
half years, all but the fifty days at Jupiter would be spent in
timeless hibernation. When he returned, the gap between their ages
would have narrowed by more than two years.
He would have sacrificed the present so that they could share a
longer future together.
The months contracted to weeks, the weeks dwindled to days, the
days shrivelled to hours; and suddenly Heywood Floyd was once more
at the Cape - spaceward-bound for the first time since that trip to
Clavius Base and the Tycho monolith, so many years ago.
But this time he was not alone, and there was no secrecy about the
mission. A few seats ahead of him rode Dr Chandra, already engaged
in a dialogue with his briefcase computer, and quite oblivious to
his surroundings.
One of Floyd's secret amusements, which he had never confided to
anyone, was spotting similarities between human beings and animals.
The resemblances were more often flattering than insulting, and his
little hobby was also a very useful aid to memory.
Dr Chandra was easy - the adjective birdlike sprang instantly to
mind. He was tiny, delicate, and all his movements were swift and
precise. But which bird? Obviously a very intelligent one. Magpie?
Too perky and acquisitive. Owl? No - too slow-moving. Perhaps
sparrow would do nicely.
Walter Curnow, the systems specialist who would have the formidable
job of getting Discovery operational again, was a more difficult
matter. He was a large, husky man, certainly not at all birdlike.
One could usually find a match somewhere in the vast spectrum of
dogs, but no canine seemed to fit. Of course - Curnow was a bear.
Not the sulky, dangerous kind, but the friendly good-natured type.
And perhaps this was appropriate; it reminded Floyd of the Russian
colleagues he would soon be joining. They had been up in orbit for
days, engaged in their final checks.
This is the great moment of my life, Floyd told himself. Now I am
leaving on a mission that may determine the future of the human
race. But he did not feel any sense of exultation; all he could
think of, during the last minutes of the countdown, were the words
he had whispered just before he had left home: 'Goodbye, my dear
little son; will you remember me when I return?' And he still felt
resentment toward Caroline because she would not awaken the
sleeping child for one final embrace; yet he knew that she had been
wise, and it was better that way.
His mood was shattered by a sudden explosive laugh; Dr Curnow was
sharing a joke with his companions - as well as a large bottle that
he handled as delicately as a barely subcritical mass of
plutonium.
'Hey, Heywood,' he called, 'they tell me Captain Orlova's locked up
all the drinks, so this is your last chance. Château Thierry
'95. Sorry about the plastic cups.'
As Floyd sipped at the really superb champagne, he found himself
cringing mentally at the thought of Curnow's guffaw reverberating
all the way across the Solar System. Much as he admired the
engineer's, ability, as a travelling companion Curnow might prove
something of a strain. At least Dr Chandra would not present such
problems; Floyd could hardly imagine him smiling, let alone
laughing. And, of course, he turned down the champagne with a
barely perceptible shudder. Curnow was polite enough, or glad
enough, not to insist.
The engineer was, it seemed, determined to be the life and soul of
the party. A few minutes later he produced a two-octave electronic
keyboard, and gave rapid renderings of 'D'ye ken John Peel' as
performed successively by piano, trombone, violin, flute, and full
organ, with vocal accompaniment. He was really very good, and Floyd
soon found himself singing along with the others. But it was just
as well, he thought, that Curnow would spend most of the voyage in
silent hibernation.
The music died with a sudden despairing discord as the engines
ignited and the shuttle launched itself into the sky. Floyd was
gripped by a familiar but always new exhilaration - the sense of
boundless power, carrying him up and away from the cares and duties
of Earth. Men knew better than they realized, when they placed the
abode of the gods beyond the reach of gravity. He was flying toward
that realm of weightlessness; for the moment, he would ignore the
fact that out there lay not freedom, but the greatest
responsibility of his career.
As the thrust increased, he felt the weight of worlds upon his
shoulders - but he welcomed it, like an Atlas who had not yet tired
of his burden. He did not attempt to think, but was content to
savour the experience. Even if he was leaving Earth for the last
time, and saying farewell to all that he had ever loved, he felt no
sadness. The roar that surrounded him was a paean of triumph,
sweeping away all minor emotions.
He was almost sorry when it ceased, though he welcomed the easier
breathing and the sudden sense of freedom. Most of the other
passengers started to unbuckle their safety straps, preparing to
enjoy the thirty minutes of zero gravity during the transfer orbit,
but a few who were obviously making the trip for the first time
remained in their seats, looking around anxiously for the cabin
attendants.
'Captain speaking. We're now at an altitude of three hundred
kilometres, coming up over the west coast of Africa. You won't see
much as it's night down there - that glow ahead is Sierra Leone -
and there's a big tropical storm over the Gulf of Guinea. Look at
those flashes!
'We'll have sunrise in fifteen minutes. Meanwhile I'm rolling the
ship so you can get a good view of the equatorial satellite belt.
The brightest one - almost straight overhead - is Intelsat's
Atlantic-1 Antenna Farm. Then Intercosmos 2 to the west - that
fainter star is Jupiter. And if you look just below that, you'll
see a flashing light, moving against the star background - that's
the new Chinese space-station. We pass within a hundred kilometres,
not close enough to see anything with the naked eye -,
What were they up to? Floyd thought idly. He had examined the
close-ups of the squat cylindrical structure with its curious
bulges, and saw no reason to believe the alarmist rumours that it
was a laser-equipped fortress. But while the Beijing Academy of
Science ignored the UN Space Committee's repeated requests for a
tour of inspection, the Chinese only had themselves to blame for
such hostile propaganda.
The "Cosmonaut Alexei Leonov" was not a thing of beauty; but few
spacecraft ever were. One day, perhaps, the human race would
develop a new aesthetic; generations of artists might arise whose
ideals were not based upon the natural forms of Earth moulded by
wind and water. Space itself was a realm of often overpowering
beauty; unfortunately, Man's hardware did not yet live up to
it.
Apart from the four huge propellant tanks, which would be dropped
off as soon as the transfer orbit was achieved, Leonov was
surprisingly small. From heat shield to drive units was less than
fifty metres; it was hard to believe that so modest a vehicle,
smaller than many commercial aircraft, could carry ten men and
women halfway across the Solar System.
But zero gravity, which made walls and roof and floor
interchangeable, rewrote all the rules of living. There was plenty
of room aboard Leonov even when everyone was awake at the same
time, as was certainly the case at the moment. Indeed, her normal
complement was at least doubled by assorted newsmen, engineers
making final adjustments, and anxious officials.
As soon as the shuttle had docked, Floyd tried to find the cabin he
would share - a year hence, when he awoke - with Curnow and
Chandra. When he did locate it, he discovered that it was packed so
tightly with neatly labelled boxes of equipment and provisions that
entry was almost impossible. He was wondering glumly how to get a
foot in the door when one of the crew, launching himself skilfully
from handhold to handhold, noticed Floyd's dilemma and braked to a
halt.
'Dr Floyd - welcome aboard. I'm Max Brailovsky - assistant
engineer.'
The young Russian spoke the slow, careful English of a student who
had had more lessons with an electronic tutor than a human teacher.
As they shook hands, Floyd matched the face and name to the set of
crew biographies he had already studied: Maxim Andreievitch
Brailovsky, age thirty-one, born Leningrad, specializing in
structure; hobbies: fencing, skycycling, chess.
'Glad to meet you,' said Floyd. 'But how do I get inside?'
'Not to worry,' said Max cheerfully. 'All that will be gone when
you wake up. It's - what do you say? - expendables. We'll eat your
room empty by the time you need it. I promise.' He patted his
stomach.
'Fine - but meanwhile where do I put my things?' Floyd pointed to
the three small cases, total mass fifty kilograms, which contained
- he hoped - everything he needed for the next couple of billion
kilometres. It had been no easy task, shepherding their weightless,
but not inertialess, bulk through the ship's corridors with only a
few collisions.
Max took two of the bags, glided gently through the triangle formed
by three intersecting girders, and dived into a small hatchway,
apparently defying Newton's First Law in the process. Floyd
acquired a few extra bruises while following him; after a
considerable time - Leonov seemed much bigger inside than out- they
arrived at a door labelled CAPTAIN, in both Cyrillic and Roman.
Although he could read Russian much better than he could speak it,
Floyd appreciated the gesture; he had already noticed that all
ship's notices were bilingual.
At Max's knock, a green light flashed on, and Floyd drifted inside
as gracefully as he could. Though he had spoken to Captain Orlova
many times, they had never before met. So he had two surprises.
It was impossible to judge a person's real size over the viewphone;
the camera somehow converted everyone to the same scale. Captain
Orlova, standing - as well as one could stand in zero gravity -
barely reached to Floyd's shoulders. The viewphone had also
completely failed to convey the penetrating quality of those
dazzling blue eyes, much the most striking feature of a face that,
at the moment, could not be fairly judged for beauty.
'Hello, Tanya,' said Floyd. 'How nice to meet at last. But what a
pity about your hair.'
They grasped both hands, like old friends.
'And nice to have you aboard, Heywood!' answered the captain. Her
English, unlike Brailovsky's, was quite fluent, though heavily
accented. 'Yes, I was sorry to lose it - but hair's a nuisance on
long missions, and I like to keep the local barbers away as long as
possible. And my apologies about your cabin; as Max will have
explained, we suddenly found we needed another ten cubic metres of
storage space. Vasili and I won't be spending much time here for
the next few hours - please feel free to use our quarters.'
'Thank you. What about Curnow and Chandra?'
'I've made similar arrangements with the crew. It may seem as if
we're treating you like cargo -'
'Not wanted on voyage.'
'Pardon?'
'That's a label they used to put on the baggage, in the old days of
ocean travel.'
Tanya smiled. 'It does look rather that way. But you'll be wanted
all right, at the end of the trip. We're already planning your
revival party.'
'That sounds too religious. Make it - no, resurrection would be
even worse! - waking-up party. But I can see how busy you are - let
me dump my things and continue my grand tour.'
'Max will show you around - take Dr Floyd to Vasili, will you? He's
down in the drive unit.'
As they drifted out of the captain's quarters, Floyd gave mental
good marks to the crew-selection committee. Tanya Orlova was
impressive enough on paper; in the flesh she was almost
intimidating, despite her charm. I wonder what she's like, Floyd
asked himself, when she loses her temper. Would it be fire or ice?
On the whole, I'd prefer not to find out.
Floyd was rapidly acquiring his space legs; by the time they
reached Vasili Orlov, he was manoeuvring almost as confidently as
his guide. The chief scientist greeted Floyd as warmly as his wife
had.
'Welcome aboard, Heywood. How do you feel?'
'Fine, apart from slowly starving to death.'
For a moment Orlov looked puzzled; then his face split into a broad
smile,
'Oh, I'd forgotten. Well, it won't be for long. In ten months'
time, you can eat as much as you like.'
Hibernators went on a low-residue diet a week in advance; for the
last twenty-four hours, they took nothing but liquid. Floyd was
beginning to wonder how much of his increasing light-headedness was
due to starvation, how much to Curnow's champagne, and how much to
zero gravity.
To concentrate his mind, he scanned the multicoloured mass of
plumbing that surrounded them.
'So this is the famous Sakharov Drive. It's the first time I've
seen a full-scale unit.'
'It's only the fourth one ever built.'
'I hope it works.'
'It had better. Otherwise, the Gorky City Council will be renaming
Sakharov Square again.'
It was a sign of the times that a Russian could joke, however
wryly, about his country's treatment of its greatest scientist.
Floyd was again reminded of Sakharov's eloquent speech to the
Academy, when he was belatedly made Hero of the Soviet Union.
Prison and banishment, he had told his listeners, were splendid
aids to creativity; not a few masterpieces had been born within the
walls of cells, beyond the reach of the world's distractions. For
that matter, the greatest single achievement of the human
intellect, the Principia itself, was a product of Newton's
self-imposed exile from plague-ridden London.
The comparison was not immodest; from those years in Gorky had come
not only new insights into the structure of matter and the origin
of the Universe, but the plasma-controlling concepts that had led
to practical thermonuclear power. The drive itself, though the
best-known and most publicized outcome of that work, was merely one
byproduct of that astonishing intellectual outburst. The tragedy
was that such advances had been triggered by injustice; one day,
perhaps, humanity would find more civilized ways of managing its
affairs.
By the time they had left the chamber, Floyd had learned more about
the Sakharov Drive than he really wished to know, or expected to
remember. He was well acquainted with its basic principles - the
use of a pulsed thermonuclear reaction to heat and expel virtually
any propellant material. The best results were obtained with pure
hydrogen as a working fluid, but that was excessively bulky and
difficult to store over long periods of time. Methane and ammonia
were acceptable alternatives; even water could be used, though with
considerably poorer efficiency.
Leonov would compromise; the enormous liquid hydrogen tanks that
provided the initial impetus would be discarded when the ship had
attained the necessary speed to carry it to Jupiter. At the
destination, ammonia would be used for the braking and rendezvous
manoeuvres, and the eventual return to Earth.
That was the theory, checked and rechecked in endless tests and
computer simulations. But as the ill-fated Discovery had shown so
well, all human plans were subject to ruthless revision by Nature,
or Fate, or whatever one preferred to call the powers behind the
Universe.
'So there you are, Dr Floyd,' said an authoritative female voice,
interrupting Vasili's enthusiastic explanation of
magnetohydrodynamic feedback, 'Why didn't you report to me?'
Floyd rotated slowly on his axis by gently torquing himself with
one hand. He saw a massive, maternal figure wearing a curious
uniform adorned with dozens of pockets and pouches; the effect was
not unlike that of a Cossack trooper draped with cartridge
belts.
'Nice to meet you again, Doctor. I'm still exploring - I hope
you've received my medical report from Houston.'
'Those vets at Teague! I wouldn't trust them to recognize
foot-and-mouth disease!'
Floyd knew perfectly well the mutual respect felt between Katerina
Rudenko and the Olin Teague Medical Center, even if the doctor's
broad grin had not discounted her words. She saw his look of frank
curiosity, and proudly fingered the webbing around her ample
waist.
'The conventional little black bag isn't very practical in zero
gravity - things float out of it and aren't there when you need
them. I designed this myself, it's a complete minisurgery. With
this, I could remove an appendix - or deliver a baby.'
'I trust that particular problem won't arise here.'
'Ha! A good doctor has to be ready for everything.'
What a contrast, thought Floyd, between Captain Orlova and Dr - or
should he call her by her correct rank of Surgeon-Commander? -
Rudenko. The captain had the grace and intensity of a prima
ballerina; the doctor might have been the prototype of Mother
Russia - stocky build, flat peasant face, needing only a shawl to
complete the picture. Don't let that fool you, Floyd told himself.
This is the woman who saved at least a dozen lives during the
Komarov docking accident - and, in her spare time, manages to edit
the Annals of Space Medicine. Consider yourself very lucky to have
her aboard.
'Now, Dr Floyd, you're going to have plenty of time later to
explore our little ship. My colleagues are too polite to say this,
but they've work to do and you're in the way. I'd like to get you -
all three of you - nice and peaceful as quickly as we can. Then
we'll have less to worry about.'
'I was afraid of that, but I quite see your point of view. I'm
ready as soon as you are.'
'I'm always ready. Come along - please.'
The ship's hospital was just large enough to hold an operating
table, two exercise bicycles, a few cabinets of equipment, and an
X-ray machine. While Dr Rudenko was giving Floyd a quick but
thorough examination, she asked unexpectedly: 'What's that little
gold cylinder Dr Chandra carries on the chain around his neck -
some kind of communications device? He wouldn't take it off - in
fact, he was almost too shy to take anything off.'
Floyd could not help smiling; it was easy to imagine the modest
Indian's reactions to this rather overwhelming lady.
'It's a lingam.'
'A what?'
'You're the doctor - you ought to recognize it. The symbol of male
fertility.'
'Of course - stupid of me. Is he a practising Hindu? It's a little
late to ask us to arrange a strict vegetarian diet.'
'Don't worry - we wouldn't have done that to you without fair
warning. Though he won't touch alcohol, Chandra's not fanatical
about anything except computers. He once told me that his
grandfather was a priest in Benares, and gave him that lingam -
it's been in the family for generations.'
Rather to Floyd's surprise, Dr Rudenko did not show the negative
reaction he had expected; indeed, her expression became
uncharacteristically wistful.
'I understand his feeling. My grandmother gave me a beautiful icon
- sixteenth century. I wanted to bring it - but it weighs five
kilos.'
The doctor became abruptly businesslike again, gave Floyd a
painless injection with a gas-gun hypodermic, and told him to come
back as soon as he was sleepy. That, she assured him, would be in
less than two hours.
'Meanwhile, relax completely,' she ordered. 'There's an observation
port on this level - Station D.6. Why don't you go there?'
It seemed a good idea, and Floyd drifted away with a docility that
would have surprised his friends. Dr Rudenko glanced at her watch,
dictated a brief entry into her autosec, and set its alarm thirty
minutes ahead.
When he reached the D.6 viewport, Floyd found Chandra and Curnow
already there. They looked at him with a total lack of recognition,
then turned once more toward the awesome spectacle outside. It
occurred to Floyd - and he congratulated himself on such a
brilliant observation - that Chandra could not really be enjoying
the view. His eyes were tightly closed,
A totally unfamiliar planet hung there, gleaming with glorious
blues and dazzling whites. How strange, Floyd told himself. What
has happened to the Earth? Why, of course - no wonder he didn't
recognize it! It was upside down! What a disaster - he wept briefly
for all those poor people, falling off into space..
He barely noticed when two crew members removed Chandra's
unresisting form. When they came back for Curnow, Floyd's own eyes
were shut, but he was still breathing. When they returned for him,
even his breathing had ceased.
And they told us we wouldn't dream, thought Heywood Floyd, more
with surprise than annoyance. The glorious pink glow that
surrounded him was very soothing; it reminded him of barbecues and
the crackling logs of Christmas fire. But there was no warmth;
indeed, he felt a distinct though not uncomfortable coldness.
Voices were murmuring, just too softly for him to understand the
words. They became louder - but still he could not understand.
'Surely,' he said in sudden amazement, 'I can't be dreaming in
Russian!'
'No, Heywood,' answered a woman's voice. 'You're not dreaming. It's
time to get out of bed.'
The lovely glow faded; he opened his eyes, and had a blurred
glimpse of a flashlight being withdrawn from his face. He was lying
on a couch, held against it by elastic webbing; figures were
standing around him, but they were too out of focus to
identify.
Gentle fingers closed his eyelids and massaged his forehead.
'Don't exert yourself. Breathe deeply... again... that's right...
now how do you feel?'
'I don't know... strange... light-headed... and hungry.'
'That's a good sign. Do you know where you are? You can open your
eyes now.'
The figures came into focus - first Dr Rudenko, then Captain
Orlova. But something had happened to Tanya since he had seen her,
only an hour ago. When Floyd identified the cause, it was almost a
physical shock.
'You've grown your hair back!'
'I hope you think it's an improvement. I can't say the same about
your beard.'
Floyd lifted his hand to his face, finding that he had to make a
conscious effort to plan every stage of the movement. His chin was
covered with short stubble - a two or three days' growth. In
hibernation, hair grew at only a hundredth of its normal rate.
'So I made it,' he said. 'We've arrived at Jupiter.'
Tanya looked at him sombrely, then glanced at the doctor, who gave
a barely perceptible nod.
'No, Heywood,' she said. 'We're still a month away. Don't be
alarmed - the ship's fine, and everything's running normally. But
your friends in Washington have asked us to wake you up ahead of
time. Something very unexpected has happened. We're in a race to
reach Discovery - and I'm afraid we're going to lose.'
When Heywood Floyd's voice came from the comset speaker, the two
dolphins suddenly stopped circling around the pool and swam over to
its edge. They placed their heads on the rim and stared intently at
the source of the sound.
So they recognize Heywood, thought Caroline, with a twinge of
bitterness: Yet Christopher, crawling around his playpen, did not
even stop playing with the colour controls of his picture book as
his father's voice came loud and clear across half a billion
kilometres of space.
'... My dear, you won't be surprised to hear from me, a month ahead
of schedule; you'll have known for weeks that we have company out
here.
'I still find it hard to believe; in some ways, it doesn't even
make sense. They can't possibly have enough fuel for a safe return
to Earth; we don't even see how they can make the rendezvous.
'We never saw them, of course. Even at its closest, Tsien was more
than fifty million kilometres away. They had plenty of time to
answer our signals if they wanted to, but they ignored us
completely. Now they'll be much too busy for friendly chat. In a
few hours they'll hit Jupiter's atmosphere - and then we'll see how
well their aerobraking system works. If it does its job, that will
be good for our morale. But if it fails, well, let's not talk about
that.
'The Russians are taking it remarkably well, all things considered.
They're angry and disappointed, of course - but I've heard many
expressions of frank admiration. It was certainly a brilliant
trick, building that ship in full view and making everyone think it
was a spacestation until they hitched on those boosters.
'Well, there's nothing we can do, except watch. And at our
distance, we won't have a much better view than your best
telescopes. I can't help wishing them luck, though of course I hope
they leave Discovery alone. That's our property, and I bet the
State Department's reminding them of it, every hour on the
hour.
'It's an ill wind - if our Chinese friends hadn't jumped the gun on
us, you wouldn't have heard from me for another month. But now that
Dr Rudenko's woken me up, I'll be speaking to you every couple of
days.
'After the initial shock, I'm settling down nicely- getting to know
the ship and its crew, finding my space legs. And polishing up my
lousy Russian, though I don't have much chance of using it -
everyone insists on speaking English.
What shocking linguists we Americans are! I sometimes feel ashamed
of our chauvinism - or our laziness.
'The standard of on-board English ranges from absolutely perfect -
Chief Engineer Sasha Kovalev could earn a living as a BBC announcer
- down to the
if-you-talk-fast-enough-it-doesn't-matter-how-many-mistakes-you-make
variety. The only one who isn't fluent is Zenia Marchenko, who
replaced Irma Yakunina at the last moment. Incidentally, I'm glad
to hear that Irma made a good recovery - what a disappointment that
must have been! I wonder if she's started hang-gliding again.
'And speaking of accidents, it's obvious that Zenia must also have
had a very bad one. Though the plastic surgeons have done a
remarkable job, you can tell that she must have been severely
burned at some time. She's the baby of the crew and the others
treat her with - I was going to say pity, but that's too
condescending. Let's say with special kindness.
'Maybe you're wondering how I get on with Captain Tanya. Well, I
like her very much - but I'd hate to make her angry. There's no
doubt exactly who runs this ship.
'And Surgeon-Commander Rudenko - you met her at the Honolulu
Aerospace Convention two years ago, and I'm sure you won't have
forgotten that last party. You'll understand why we all call her
Catherine the Great - behind her broad back, of course.
'But that's enough gossip. If I run overtime, I hate to think of
the surcharge. And by the way, these personal calls are supposed to
be completely private. But there are a lot of links in the
communications chain, so don't be surprised if you occasionally get
messages by - well, another route.
'I'll be waiting to hear from you - tell the girls I'll be speaking
to them later. My love to you all - I miss you and Chris very
badly. And when I get back, I promise I'll never leave again.'
There was a brief hissing pause, then an obviously synthetic voice
said: 'This terminates Transmission Four Hundred Thirty-two Stroke
Seven from Spacecraft Leonov.' As Caroline Floyd switched off the
speaker, the two dolphins slid beneath the surface of the pool and
glided out into the Pacific, leaving scarcely a ripple in the
water.
When he realized that his friends were gone, Christopher began to
cry. His mother picked him up in her arms and tried to comfort him,
but it was a long time before she succeeded.
The image of Jupiter, with its ribbons of white cloud, its mottled
bands of salmon pink, and the Great Red Spot staring out like a
baleful eye, hung steady on the flight-deck projection screen. It
was three-quarters full, but no one was looking at the illuminated
disk; all eyes were focused on the crescent of darkness at its
edge. There, over the nightside of the planet, the Chinese ship was
about to meet its moment of truth.
This is absurd, thought Floyd. We can't possibly see anything
across forty million kilometres. And it doesn't matter; the radio
will tell us all we want to know.
Tsien had closed down all voice, video, and data circuits two hours
before, as the long-range antennas were withdrawn into the
protective shadow of the heat shield. Only the omnidirectional
beacon was still transmitting, accurately pinpointing the Chinese
ship's position as it plunged toward that ocean of continent-sized
clouds. The shrill beep... beep... beep... was the only sound in
Leonov's control room. Each of those pulses had left Jupiter more
than two minutes earlier; by this time, their source might already
be a cloud of incandescent gas, dispersing in the Jovian
stratosphere.
The signal was fading, becoming noisy. The beeps were getting
distorted; several dropped out completely, then the sequence
returned. A plasma sheath was building up around Tsien and soon
would cut off all communications until the ship re-emerged. If it
ever did.
'Posmotri!' cried Max. 'There it is!'
At first Floyd could see nothing. Then, just off the edge of the
illuminated disk, he made out a tiny star - gleaming where no star
could possibly be, against the darkened face of Jupiter.
It appeared quite motionless, though he knew it must be moving at a
hundred kilometres a second. Slowly it grew in brilliance; and then
it was no longer a dimensionless point, but was becoming elongated.
A man-made comet was streaking across the Jovian night sky, leaving
a trail of incandescence thousands of kilometres in length.
One last badly distorted and curiously drawn-out beep sounded from
the tracking beacon, then only the meaningless hiss of Jupiter's
own radiation, one of those many cosmic voices that had nothing to
do with Man or his works.
Tsien was inaudible, but not yet invisible. For they could see that
the tiny elongated spark had indeed moved appreciably away from the
sunward face of the planet and would soon disappear into the
nightside. By then, if all had gone according to plan, Jupiter
would have captured the ship, destroying its unwanted velocity.
When it emerged from behind the giant world, it would be another
Jovian satellite.
The spark flickered out. Tsien had rounded the curve of the planet
and was heading over the nightside. There would be nothing to see,
or to hear, until it emerged from shadow - if all went well, in
just under an hour. It would be a very long hour for the
Chinese.
To Chief Scientist Vasili Orlov and communications engineer Sasha
Kovalev, the hour went extremely quickly. There was much they could
learn from observations of that little star; its times of
appearance and disappearance and, above all, the Doppler shift of
the radio beacon gave vital information about Tsien's new orbit.
Leonov's computers were already digesting the figures, and spitting
out projected times of re-emergence based on various assumptions
about rates of deceleration in the Jovian atmosphere.
Vasili switched off the computer display, spun around in his chair,
loosened his seat belt, and addressed the patiently waiting
audience.
'Earliest reappearance is in forty-two minutes. Why don't you
spectators go for a walk, so we can concentrate on getting all this
into good shape? See you in thirty-five minutes. Shoo! Nu
ukhodi!'
Reluctantly, the unwanted bodies left the bridge - but, to Vasili's
disgust, everyone was back again in little more than thirty
minutes. He was still chiding them for their lack of faith in his
calculations when the familiar beep... beep... beep... of Tsien's
tracking beacon burst from the loudspeakers.
Vasili looked astonished and mortified, but soon joined in the
spontaneous round of applause; Floyd could not see who first
started the clapping. Rivals though they might be, they were all
astronauts together, as far from home as any men had ever travelled
- 'Ambassadors for Mankind', in the noble words of the first UN
Space Treaty. Even if they did not want the Chinese to succeed,
neither did they wish them to meet disaster.
A large element of self-interest was also involved, Floyd could not
help thinking. Now the odds in Leonov's own favour were
significantly improved; Tsien had demonstrated that the aerobraking
manoeuvre was indeed possible. The data on Jupiter was correct; its
atmosphere did not contain unexpected and perhaps fatal
surprises.
'Well!' said Tanya. 'I suppose we should send them a message of
congratulations. But even if we did, they wouldn't acknowledge
it.'
Some of his colleagues were still making fun of Vasili, who was
staring at his computer output in frank disbelief.
'I don't understand it!' he exclaimed. 'They should still be behind
Jupiter! Sasha - give me a velocity reading on their beacon!'
Another silent dialogue was held with the computer; then Vasili
gave a long, low whistle.
'Something's wrong. They're in a capture orbit, all right - but it
won't let them make a rendezvous with Discovery. The orbit they're
on now will take them way beyond Io - I'll have more accurate data
when we've tracked them for another five minutes.'
'Anyway, they must be in a safe orbit,' said Tanya. 'They can
always make corrections later.'
'Perhaps. But that could cost them days, even if they have the
fuel. Which I doubt.'
'So we may still beat them.'
'Don't be such an optimist. We're still three weeks from Jupiter.
They can make a dozen orbits before we get there, and choose the
most favourable one for a rendezvous.'
'Again - assuming that they have enough propellant.'
'Of course. And that's something we can only make educated guesses
about.'
All this conversation took place in such rapid and excited Russian
that Floyd was left far behind. When Tanya took pity on him and
explained that Tsien had overshot and was heading for the outer
satellites, his first reaction was: 'Then they may be in serious
trouble. What will you do if they appeal for help?'
'You must be making a joke. Can you imagine them doing that?
They're much too proud. Anyway, it would be impossible. We can't
change our mission profile, as you know perfectly well. Even if we
had the fuel...'
'You're right, of course; but it might be difficult to explain that
to the ninety-nine per cent of the human race that doesn't
understand orbital mechanics. We should start thinking about some
of the political complications - it would look bad for all of us if
we can't help. Vasili, will you give me their final orbit, as soon
as you've worked it out? I'm going down to my cabin to do some
homework.'
Floyd's cabin, or rather one-third of a cabin, was still partly
full of stores, many of them stacked in the curtained bunks that
would be occupied by Chandra and Curnow when they emerged from
their long slumbers. He had managed to clear a small working space
for his personal effects and had been promised the luxury of
another whole two cubic metres - just as soon as someone could be
spared to help with the furniture removing.
Floyd unlocked his little communications console, set the
decryption keys, and called for the information on Tsien that had
been transmitted to him from Washington. He wondered if his hosts
had had any luck in unscrambling it; the cipher was based on the
product of two hundred-digit prime numbers, and the National
Security Agency had staked its reputation on the claim that the
fastest computer in existence could not crack it before the Big
Crunch at the end of the Universe. It was a claim that could never
be proved - only disproved.
Once again he stared intently at the excellent photographs of the
Chinese ship, taken when it had revealed its true colours and was
just about to leave Earth orbit. There were later shots - not so
clear, because by then it had been far away from the prying cameras
- of the final stage as it hurtled toward Jupiter. Those were the
ones that interested him most; even more useful were the cutaway
drawings and estimates of performance.
Granted the most optimistic assumptions, it was difficult to see
what the Chinese hoped to do. They must have burned up at least
ninety per cent of their propellant in that mad dash across the
Solar System. Unless it was literally a suicide mission - something
that could not be ruled out - only a plan involving hibernation and
later rescue made any sense. And Intelligence did not believe that
Chinese hibernation technology was sufficiently far advanced to
make that a viable option.
But Intelligence was frequently wrong, and even more often confused
by the avalanche of raw facts it had to evaluate - the 'noise' in
its information circuits. It had done a remarkable job on Tsien,
considering the shortness of time, but Floyd wished that the
material sent to him had been more carefully filtered. Some of it
was obvious junk, of no possible connection with the mission.
Nevertheless, when you did not know what you were looking for, it
was important to avoid all prejudices and preconceptions; something
that at first sight seemed irrelevant, or even nonsensical, might
turn out to be a vital clue.
With a sigh, Floyd started once more to skim the five hundred pages
of data, keeping his mind as blankly receptive as possible while
diagrams, charts, photographs - some so smudgy that they could
represent almost anything - news items, lists of delegates to
scientific conferences, titles of technical publications, and even
commercial documents scrolled swiftly down the high-resolution
screen. A very efficient industrial espionage system had obviously
been extremely busy; who would have thought that so many Japanese
holomemory modules or Swiss gas-flow microcontrollers or German
radiation detectors could have been traced to a destination in the
dried lake bed of Lop Nor - the first milepost on their way to
Jupiter?
Some of the items must have been included by accident; they could
not possibly relate to the mission. If the Chinese had placed a
secret order for one thousand infrared sensors through a dummy
corporation in Singapore, that was only the concern of the
military; it seemed highly unlikely that Tsien expected to be
chased by heat-seeking missiles. And this one was really funny -
specialized surveying and prospecting equipment from Glacier
Geophysics, Inc., of Anchorage, Alaska. What lamebrain imagined
that a deep-space expedition would have any need - the smile froze
on Floyd's lips; he felt the skin crawl on the back of his neck. My
God - they wouldn't dare! But they had already dared greatly; and
now, at last, everything made sense.
He flashed back to the photos and conjectured plans of the Chinese
ship. Yes, it was just conceivable - those flutings at the rear,
alongside the drive deflection electrodes, would be about the right
size.
Floyd called the bridge. 'Vasili.' he said, 'have you worked out
their orbit yet?'
'Yes, I have,' the navigator replied, in a curiously subdued voice.
Floyd could tell at once that something had turned up. He took a
long shot.
'They're making a rendezvous with Europa, aren't they?'
There was an explosive gasp of disbelief from the other end.
'Chyort voz'mi! How did you know?'
'I didn't - I've just guessed it.'
'There can't be any mistake - I've checked the figures to six
places. The braking manoeuvre worked out exactly as they intended.
They're right on course for Europa - it couldn't have happened by
chance. They'll be there in seventeen hours.'
'And go into orbit.'
'Perhaps; it wouldn't take much propellant. But what would be the
point?'
'I'll risk another guess. They'll do a quick survey - and then
they'll land.'
'You're crazy - or do you know something we don't?'
'No - it's just a matter of simple deduction. You're going to start
kicking yourself for missing the obvious.'
'Okay, Sherlock, why should anyone want to land on Europa? What's
there, for heaven's sake?'
Floyd was enjoying his little moment of triumph. Of course, he
might still be completely wrong.
'What's on Europa? Only the most valuable substance in the
Universe.'
He had overdone it; Vasili was no fool, and snatched the answer
from his lips.
'Of course - water!'
'Exactly. Billions and billions of tons of it. Enough to fill up
the propellant tanks - go cruising around all the satellites, and
still have plenty left for the rendezvous with Discovery and the
voyage home. I hate to say this, Vasili - but our Chinese friends
have outsmarted us again.
'Always assuming, of course, that they can get away with it.'
Apart from the jet-black sky, the photo might have been taken
almost anywhere in the polar regions of Earth; there was nothing in
the least alien about the sea of wrinkled ice that stretched all
the way out to the horizon. Only the five spacesuited figures in
the foreground proclaimed that the panorama was of another
world.
Even now, the secretive Chinese had not released the names of the
crew. The anonymous intruders on the frozen Europan icescape were
merely the chief scientist, the commander, the navigator, the first
engineer, the second engineer. It was also ironic, Floyd could not
help thinking, that everyone on Earth had seen the already historic
photograph an hour before it reached Leonov, so much closer to the
scene. But Tsien's transmissions were relayed on such a tight beam
that it was impossible to intercept them; Leonov could receive only
its beacon, broadcasting impartially in all directions. Even that
was inaudible more than half the time, as Europa's rotation carried
it out of sight, or the satellite itself was eclipsed by the
monstrous bulk of Jupiter. All the scanty news of the Chinese
mission had to be relayed from Earth.
The ship had touched down, after its initial survey, on one of the
few islands of solid rock that protruded through the crust of ice
covering virtually the entire moon. That ice was flat from pole to
pole; there was no weather to carve it into strange shapes, no
drifting snow to build up layer upon layer into slowly moving
hills. Meteorites might fall upon airless Europa, but never a flake
of snow. The only forces moulding its surface were the steady tug
of gravity, reducing all elevations to one uniform level, and the
incessant quakes caused by the other satellites as they passed and
repassed Europa in their orbits. Jupiter itself, despite its far
greater mass, had much less effect. The Jovian tides had finished
their work aeons ago, ensuring that Europa remained locked forever
with one face turned toward its giant master.
All this had been known since the Voyager flyby missions of the
1970s, the Galileo surveys of the 1980s, and the Kepler landings of
the 1990s. But, in a few hours, the Chinese had learned more about
Europa than all the previous missions combined. That knowledge they
were keeping to themselves; one might regret it, but few would deny
that they had earned the right to do so.
What was being denied, with greater and greater asperity, was their
right to annex the satellite. For the first time in history, a
nation had laid claim to another world, and all the news media of
Earth were arguing over the legal position. Though the Chinese
pointed out, at tedious length, that they had never signed the '02
UN Space Treaty and so were not bound by its provisions, that did
nothing to quell the angry protests.
Suddenly, Europa was the biggest news in the Solar System. And the
man-on-the-spot (at least to the nearest few million kilometres)
was in great demand.
'This is Heywood Floyd, aboard Cosmonaut Alexei Leonov, on course
for Jupiter. But as you can well imagine, all our thoughts are now
focused upon Europa.
'At this very moment I'm looking at it through the most powerful of
the ship's telescopes; under this magnification, it's ten times
larger than the Moon as you see it with the naked eye. And it's a
really weird sight.
'The surface is a uniform pink, with a few small brown patches.
It's covered with an intricate network of narrow lines, curling and
weaving in all directions. In fact, it looks very much like a photo
from a medical textbook, showing a pattern of veins and
arteries.
'A few of these features are hundreds - or even thousands - of
kilometres long, and look rather like the illusory canals that
Percival Lowell and other early-twentieth-century astronomers
imagined they'd seen on Mars.
'But Europa's canals aren't an illusion, though of course they're
not artificial. What's more, they do contain water -or at least
ice. For the satellite is almost entirely covered by ocean,
averaging fifty kilometres deep.
'Because it's so far from the sun, Europa's surface temperature is
extremely low - about a hundred and fifty degrees below freezing.
So one might expect its single ocean to be a solid block of
ice.
'Surprisingly, that isn't the case because there's a lot of heat
generated inside Europa by tidal forces - the same forces that
drive the great volcanoes on neighbouring Io.
'So the ice is continually melting, breaking up, and freezing,
forming cracks and lanes like those in the floating ice sheets in
our own polar regions. It's that intricate tracery of cracks I'm
seeing now; most of them are dark and very ancient - perhaps
millions of years old. But a few are almost pure white; they're the
new ones that have just opened up, and have a crust only a few
centimetres thick.
'Tsien has landed right beside one of these white streaks -the
fifteen-hundred-kilometre-long feature that's been christened the
Grand Canal. Presumably the Chinese intend to pump its water into
their propellant tanks, so that they can explore the Jovian
satellite system and then return to Earth. That may not be easy,
but they'll certainly have studied the landing site with great
care, and must know what they're doing.
'It's obvious, now, why they've taken such a risk - and why they
should claim Europa. As a refuelling point, it could be the key to
the entire outer Solar System. Though there's also water on
Ganymede, it's all frozen, and also less accessible because of that
satellite's more powerful gravity.
'And there's another point that's just occurred to me. Even if the
Chinese do get stranded on Europa, they might be able to survive
until a rescue mission is arranged. They have plenty of power,
there may be useful minerals in the area - and we know that the
Chinese are the experts on synthetic-food production. It wouldn't
be a very luxurious life; but I have some friends who would accept
it happily for that staggering view of Jupiter sprawled across the
sky - the view we expect to see ourselves, in just a few days.
'This is Heywood Floyd, saying goodbye for my colleagues and
myself, aboard Alexei Leonov.'
'And this is the bridge. Very nice presentation, Heywood. You
should have been a newsman.'
'I've had plenty of practice. Half my time was spent on PR
work.'
'PR?'
'Public relations - usually telling politicians why they should
give me more money. Something you don't have to bother about.'
'How I wish that was true. Anyway, come up to the bridge. There's
some new information we'd like to discuss with you.'
Floyd removed his button microphone, locked the telescope into
position and extricated himself from the tiny viewing blister. As
he left, he almost collided with Nikolai Temovsky, obviously on a
similar mission.
'I'm about to steal your best quotes for Radio Moscow, Woody. Hope
you don't mind.'
'You're welcome, tovarishch. Anyway, how could I stop you?'
Up on the bridge, Captain Orlova was looking thoughtfully at a
dense mass of words and figures on the main display. Floyd had
painfully started to transliterate them when she interrupted
him.
'Don't worry about the details. These are estimates of the time it
will take for Tsien to refill its tanks and get ready for
lift-off.'
'My people are doing the same calculations - but there are far too
many variables.'
'We think we've removed one of them. Did you know that the very
best water pumps you can buy belong to fire brigades? And would you
be surprised to learn that the Beijing Central Station had four of
its latest models suddenly requisitioned a few months ago, despite
the protests of the mayor?'
'I'm not surprised - merely lost in admiration. Go on, please.'
'That may be a coincidence, but those pumps would be just the right
size. Making educated guesses about pipe deployment, drilling
through the ice and so on - well, we think they could lift off
again in five days.'
'Five days!'
'If they're lucky, and everything works perfectly. And if they
don't wait to fill their propellant tanks but merely take on just
enough for a safe rendezvous with Discovery before we do. Even if
they beat us by a single hour, that would be enough. They could
claim salvage rights, at the very least.'
'Not according to the State Department's lawyers. At the
appropriate moment, we'll declare that Discovery is not a derelict,
but has merely been parked until we can retrieve it. Any attempt to
take over the ship would be an act of piracy.'
'I'm sure the Chinese will be most impressed.'
'If they're not, what can we do about it?'
'We outnumber them - and two to one, when we revive Chandra and
Curnow.'
'Are you serious? Where are the cutlasses for the boarding
party?'
'Cutlasses?'
'Swords - weapons.'
'Oh. We could use the laser telespectrometer. That can vaporize
milligram asteroid samples at ranges of a thousand kilometres.'
'I'm not sure that I like this conversation. My government
certainly would not condone violence, except of course in
self-defence.'
'You naive Americans! We're more realistic; we have to be. All your
grandparents died of old age, Heywood. Three of mine were killed in
the Great Patriotic War.'
When they were alone together, Tanya always called him Woody, never
Heywood. She must be serious. Or was she merely testing his
reactions?
'Anyway, Discovery is merely a few billion dollars' worth of
hardware. The ship's not important - only the information it
carries.'
'Exactly. Information that could be copied, and then erased.'
'You do get some cheerful ideas, Tanya. Sometimes I think that all
Russians are a little paranoiac.'
'Thanks to Napoleon and Hitler, we've earned every right to be. But
don't tell me that you haven't already worked out that - what do
you call it, scenario? - for yourself.'
'It wasn't necessary,' Floyd answered rather glumly. 'The State
Department's already done it for me - with variations. We'll just
have to see which one the Chinese come up with. And I wouldn't be
in the least surprised if they outguess us again.'
Sleeping in zero gravity is a skill that has to be learned; it had
taken Floyd almost a week to find the best way of anchoring legs
and arms so that they did not drift into uncomfortable positions.
Now he was an expert, and was not looking forward to the return of
weight; indeed, the very idea gave him occasional nightmares.
Someone was shaking him awake. No - he must still be dreaming!
Privacy was sacred aboard a spaceship; nobody ever entered another
crew member's chambers without first asking permission. He clenched
his eyes shut, but the shaking continued.
'Dr Floyd - please wake up! You're wanted on the flight deck!'
And nobody called him Dr Floyd; the most formal salutation he had
received for weeks was Doc. What was happening?
Reluctantly, he opened his eyes. He was in his tiny cabin, gently
gripped by his sleeping cocoon. So one part of his mind told him;
then why was he looking at - Europa? They were still millions of
kilometres away.
There were the familiar reticulations, the patterns of triangles
and polygons formed by intersecting lines. And surely that was the
Grand Canal itself - no, it wasn't quite right. How could it be,
since he was still in his little cabin aboard Leonov?
'Dr Floyd!'
He became fully awake, and realized that his left hand was floating
just a few centimetres in front of his eyes. How strange that the
pattern of lines across the palm was so uncannily like the map of
Europa! But economical Mother Nature was always repeating herself,
on such vastly different scales as the swirl of milk stirred into
coffee, the cloud lanes of a cyclonic storm, the arms of a spiral
nebula.
'Sorry, Max,' he said. 'What's the problem? Is something
wrong?'
'We think so - but not with us. Tsien's in trouble.'
Captain, navigator, and chief engineer were strapped in their seats
on the flight deck; the rest of the crew orbited anxiously around
convenient handholds, or watched on the monitors.
'Sorry to wake you up, Heywood,' Tanya apologized brusquely.
'Here's the situation. Ten minutes ago we had a Class One Priority
from Mission Control. Tsien's gone off the air. It happened very
suddenly, in the middle of a cipher message; there were a few
seconds of garbled transmission - then nothing.'
'Their beacon?'
'That's stopped as well. We can't receive it either,'
'Phew! Then it must be serious - a major breakdown. Any
theories?'
'Lots - but all guesswork. An explosion - landslide - earthquake:
who knows?'
'And we may never know - until someone else lands on Europa - or we
do a close flyby and take a look.'
Tanya shook her head. 'We don't have enough delta-vee. The closest
we could get is fifty thousand kilometres. Not much you could see
from that distance.'
'Then there's absolutely nothing we can do.'
'Not quite, Heywood. Mission Control has a suggestion. They'd like
us to swing our big dish around, just in case we can pick up any
weak emergency transmissions. It's - how do you say? - a long shot,
but worth trying. What do you think?'
Floyd's first reaction was strongly negative.
'That will mean breaking our link with Earth.'
'Of course; but we'll have to do that anyway, when we go around
Jupiter. And it will only take a couple of minutes to re-establish
the circuit.'
Floyd remained silent. The suggestion was perfectly reasonable, yet
it worried him obscurely. After puzzling for several seconds, he
suddenly realized why he was so opposed to the idea.
Discovery's troubles had started when the big dish - the main
antenna complex - had lost its lock on Earth, for reasons which
even now were not completely clear. But Hal had certainly been
involved, and there was no danger of a similar situation arising
here. Leonov's computers were small, autonomous units; there was no
single controlling intelligence. At least, no nonhuman one.
The Russians were still waiting patiently for his answer.
'I agree,' he said at last. 'Let Earth know what we're doing, and
start listening. I suppose you'll try all the SPACE MAYDAY
frequencies.'
'Yes, as soon as we've worked out the Doppler corrections. How's it
going, Sasha?'
'Give me another two minutes, and I'll have the automatic search
running. How long should we listen?'
The captain barely paused before giving her answer. Floyd had often
admired Tanya Orlova's decisiveness, and had once told her so. In a
rare flash of humour, she had replied: 'Woody, a commander can be
wrong, but never uncertain.'
'Listen for fifty minutes, and report back to Earth for ten. Then
repeat the cycle.'
There was nothing to see or hear; the automatic circuits were
better at sifting the radio noise than any human senses.
Nevertheless, from time to time Sasha turned up the audio monitor,
and the roar of Jupiter's radiation belts filled the cabin. It was
a sound like the waves breaking on all the beaches of Earth, with
occasional explosive cracks from superbolts of lightning in the
Jovian atmosphere. Of human signals, there was no trace; and, one
by one, the members of the crew not on duty drifted quietly
away.
While he was waiting, Floyd did some mental calculations. Whatever
had happened to Tsien was already two hours in the past, since the
news had been relayed from Earth.
But Leonov should be able to pick up a direct message after less
than a minute's delay, so the Chinese had already had ample time to
get back on the air. Their continued silence suggested some
catastrophic failure, and he found himself weaving endless
scenarios of disaster.
The fifty minutes seemed like hours. When they were up, Sasha swung
the ship's antenna complex back toward Earth, and reported failure.
While he was using the rest of the ten minutes to send a backlog of
messages, he looked inquiringly at the captain.
'Is it worth trying again?' he said in a voice that clearly
expressed his own pessimism.
'Of course. We may cut back the search time - but we'll keep
listening.'
On the hour, the big dish was once more focused upon Europa. And
almost at once, the automatic monitor started flashing its ALERT
light.
Sasha's hand darted to the audio gain, and the voice of Jupiter
filled the cabin. Superimposed upon that, like a whisper heard
against a thunderstorm, was the faint but completely unmistakable
sound of human speech. It was impossible to identify the language,
though Floyd felt certain, from the intonation and rhythm, that it
was not Chinese, but some European tongue.
Sasha played skilfully with fine-tuning and band-width controls,
and the words became clearer. The language was undoubtedly English
- but its content was still maddeningly unintelligible.
There is one combination of sounds that every human ear can detect
instantly, even in the noisiest environment. When it suddenly
emerged from the Jovian background, it seemed to Floyd that he
could not possibly be awake, but was trapped in some fantastic
dream. His colleagues took a little longer to react; then they
stared at him with equal amazement - and a slowly dawning
suspicion.
- For the first recognizable words from Europa were: 'Dr Floyd - Dr
Floyd - I hope you can hear me.'
'Who is it?' whispered someone, to a chorus of shushes. Floyd
raised his hands in a gesture of ignorance - and, he hoped,
innocence.
'... know you are aboard Leonov... may not have much time... aiming
my suit antenna where I think...' The signal vanished for agonizing
seconds, then came back much clearer, though not appreciably
louder.
'... relay this information to Earth. Tsien destroyed three hours
ago. I'm only survivor. Using my suit radio - no idea if it has
enough range, but it's the only chance. Please listen carefully.
THERE IS LIFE ON EUROPA. I repeat: THERE IS LIFE ON EUROPA.'
The signal faded again. A stunned silence followed that no one
attempted to interrupt. While he was waiting, Floyd searched his
memory furiously. He could riot recognize the voice - it might have
been that of any Western-educated Chinese. Probably it was someone
he had met at a scientific conference, but unless the speaker
identified himself he would never know.
'... soon after local midnight. We were pumping steadily and the
tanks were almost half full. Dr Lee and I went out to check the
pipe insulation. Tsien stands - stood - about thirty metres from
the edge of the Grand Canal. Pipes go directly from it and down
through the ice. Very thin - not safe to walk on. The warm
upwelling...'
Again a long silence. Floyd wondered if the speaker was moving, and
had been momentarily cut off by some obstruction.
'... no problem - five kilowatts of lighting strung up on the ship.
Like a Christmas tree - beautiful, shining right through the ice.
Glorious colours. Lee saw it first - a huge dark mass rising up
from the depths. At first we thought it was a school of fish - too
large for a single organism - then it started to break through the
ice.
'Dr Floyd, I hope you can hear me. This is Professor Chang - we met
in '02 - Boston IAU conference.'
Instantly, incongruously, Floyd's thoughts were a billion
kilometres away. He vaguely remembered that reception, after the
closing session of the International Astronomical Union Congress -
the last one that the Chinese had attended before the Second
Cultural Revolution. And now he recalled Chang very distinctly - a
small, humorous astronomer and exobiologist with a good fund of
jokes. He wasn't joking now.
'... like huge strands of wet seaweed, crawling along the ground.
Lee ran back to the ship to get a camera - I stayed to watch,
reporting over the radio. The thing moved so slowly I could easily
outrun it. I was much more excited than alarmed. Thought I knew
what kind of creature it was - I've seen pictures of the kelp
forests off California - but I was quite wrong.
'I could tell it was in trouble. It couldn't possibly survive at a
temperature a hundred and fifty below its normal environment. It
was freezing solid as it moved forward - bits were breaking off
like glass - but it was still advancing toward the ship, a black
tidal wave, slowing down all the time.
'I was still so surprised that I couldn't think straight and I
couldn't imagine what it was trying to do...'
'Is there any way we can call him back?' Floyd whispered
urgently.
'No - it's too late. Europa will soon be behind Jupiter. We'll have
to wait until it comes out of eclipse.'
'... climbing up the ship, building a kind of ice tunnel as it
advanced. Perhaps this was insulating it from the cold - the way
termites protect themselves from the sunlight with their little
corridors of mud.
'... tons of ice on the ship. The radio antennas broke off first.
Then I could see the landing legs beginning to buckle - all in slow
motion, like a dream.
'Not until the ship started to topple did I realize what the thing
was trying to do - and then it was too late. We could have saved
ourselves - if we'd only switched off those lights.
'Perhaps it's a phototrope, its biological cycle triggered by the
sunlight that filters through the icc, Or it could have been
attracted like a moth to a candle. Our floodlights must have been
more brilliant than anything that Europa has ever known.
'Then the ship crashed. I saw the hull split, a cloud of snowflakes
form as moisture condensed. All the lights went out, except for
one, swinging back and forth on a cable a couple of metres above
the ground.
'I don't know what happened immediately after that. The next thing
I remember, I was standing under the light, beside the wreck of the
ship, with a fine powdering of fresh snow all around me. I could
see my footsteps in it very clearly. I must have run there; perhaps
only a minute or two had elapsed.
'The plant - I still thought of it as a plant - was motionless. I
wondered if it had been damaged by the impact; large sections - as
thick as a man's arm - had splintered off, like broken twigs.
'Then the main trunk started to move again. It pulled away from the
hull, and began to crawl toward me. That was when I knew for
certain that the thing was light-sensitive: I was standing
immediately under the thousand watt lamp, which had stopped
swinging now.
'Imagine an oak tree - better still, a banyan with its multiple
trunks and roots - flattened out by gravity and trying to creep
along the ground. It got to within five metres of the light, then
started to spread out until it had made a perfect circle around me.
Presumably that was the limit of its tolerance - the point at which
photo-attraction turned to repulsion. After that, nothing happened
for several minutes. I wondered if it was dead - frozen solid at
last.
'Then I saw that large buds were forming on many of the branches.
It was like watching a time-lapse film of flowers opening. In fact
I thought they were flowers - each about as big as a man's
head.
'Delicate, beautifully coloured membranes started to unfold. Even
then, it occurred to me that no one - no thing - could ever have
seen these colours before; they had no existence until we brought
our lights - our fatal lights - to this world.
'Tendrils, stamens, waving feebly... I walked over to the living
wall that surrounded me, so that I could see exactly what was
happening. Neither then, nor at any other time, had I felt the
slightest fear of the creature. I was certain that it was not
malevolent - if indeed it was conscious at all.
'There were scores of the big flowers, in various stages of
unfolding. Now they reminded me of butterflies, just emerging from
the chrysalis - wings crumpled, still feeble - I was getting closer
and closer to the truth.
'But they were freezing - dying as quickly as they formed. Then,
one after another, they dropped off from the parent buds. For a few
moments they flopped around like fish stranded on dry land - at
last I realized exactly what they were. Those membranes weren't
petals - they were fins, or their equivalent. This was the
free-swimming, larval stage of the creature. Probably it spends
much of its life rooted on the seabed, then sends these mobile
offspring in search of new territory. Just like the corals of
Earth's oceans.
'I knelt down to get a closer look at one of the little creatures.
The beautiful colours were fading now to a drab brown. Some of the
petal-fins had snapped off, becoming brittle shards as they froze.
But it was still moving feebly, and as I approached it tried to
avoid me. I wondered how it sensed my presence.
'Then I noticed that the stamens - as I'd called them - all carried
bright blue dots at their tips. They looked like tiny star
sapphires - or the blue eyes along the mantle of a scallop - aware
of light, but unable to form true images. As I watched, the vivid
blue faded, the sapphires became dull, ordinary stones.
'Dr Floyd - or anyone else, who is listening - I haven't much more
time; Jupiter will soon block my signal. But I've almost
finished.
'I knew then what I had to do. The cable to that thousand watt lamp
was hanging almost to the ground. I gave it a few tugs, and the
light went out in a shower of sparks.
'I wondered if it was too late. For a few minutes, nothing
happened. So I walked over to the wall of tangled branches around
me, and kicked it.
'Slowly, the creature started to unweave itself, and to retreat
back to the Canal. There was plenty of light - I could see
everything perfectly. Ganymede and Callisto were in the sky -
Jupiter was a huge, thin crescent - and there was a big auroral
display on the nightside, at the Jovian end of the Io flux tube.
There was no need to use my helmet light.
'I followed the creature all the way back to the water, encouraging
it with more kicks when it slowed down, feeling the fragments of
ice crunching all the time beneath my boots... as it neared the
Canal, it seemed to gain strength and energy, as if it knew that it
was approaching its natural home. I wondered if it would survive,
to bud again.
'It disappeared through the surface, leaving a few last dead larvae
on the alien land. The exposed free water bubbled for a few minutes
until a scab of protective ice sealed it from the vacuum above.
Then I walked back to the ship to see if there was anything to
salvage - I don't want to talk about that.
'I've only two requests to make, Doctor. When the taxonomists
classify this creature, I hope they'll name it after me.
'And - when the next ship comes home - ask them to take our bones
back to China.
'Jupiter will be cutting us off in a few minutes. I wish I knew
whether anyone was receiving me. Anyway, I'll repeat this message
when we're in line of sight again - if my suit's life-support
system lasts that long.
'This is Professor Chang on Europa, reporting the destruction of
spaceship Tsien. We landed beside the Grand Canal and set up our
pumps at the edge of the ice -,
The signal faded abruptly, came back for a moment, then disappeared
completely be1ow the noise level. Although Leonov listened again on
the same frequency, there was no further message from Professor
Chang.
The ship was gaining speed at last, on the downhill run toward
Jupiter. It had long since passed the gravitational no-man's-land
where the four tiny outer moons - Sinope, Pasiphae, Ananke, and
Carme - wobbled along their retrograde and wildly eccentric orbits.
Undoubtedly captured asteroids, and completely irregular in shape,
the largest was only thirty kilometres across. Jagged, splintered
rocks of no interest to anyone except planetary geologists, their
allegiance wavered continually between the Sun and Jupiter. One
day, the Sun would recapture them completely.
But Jupiter might retain the second group of four, at half the
distance of the others. Elara, Lysithea, Himalia, and Leda were
fairly close together, and lying in almost the same plane. There
was speculation that they had once been part of a single body; if
so, the parent would have been barely a hundred kilometres
across.
Though only Carme and Leda came close enough to show disks visible
to the naked eye, they were greeted like old friends. Here was the
first landfall after the longest ocean voyage - the offshore
islands of Jupiter. The last hours were ticking away; the most
critical phase of the entire mission was approaching - the entry
into the Jovian atmosphere.
Jupiter was already larger than the Moon in the skies of Earth, and
the giant inner satellites could be clearly seen moving around it.
They all showed noticeable disks and distinctive colouring, though
they were still too far away for any markings to be visible. The
eternal ballet they performed - disappearing behind Jupiter,
reappearing to transit the daylight face with their accompanying
shadows - was an endlessly engaging spectacle. It was one that
astronomers had watched ever since Galileo had first glimpsed it
almost exactly four centuries ago; but the crew of Leonov were the
only living men and women to have seen it with unaided eyes.
The interminable chess games had ceased; off-duty hours were spent
at the telescopes, or in earnest conversation, or listening to
music, usually while gazing at the view outside. And at least one
shipboard romance had reached a culmination: the frequent
disappearances of Max Brailovsky and Zenia Marchenko were the
subject of much good-natured banter.
They were, thought Floyd, an oddly matched pair. Max was a big,
handsome blond who had been a champion gymnast, reaching the finals
of the 2000 Olympics. Though he was in his early thirties, he had
an open-faced, almost boyish expression. This was not altogether
misleading; despite his brilliant engineering record, he often
struck Floyd as naive and unsophisticated - one of those people who
are pleasant to talk to, but not for too long. Outside his own
field of undoubted expertise he was engaging but rather
shallow.
Zenia - at twenty-nine, the youngest on board - was still something
of a mystery. Since no one wished to talk about it, Floyd had never
raised the subject of her injuries, and his Washington sources
could provide no information. Obviously she had been involved in
some serious accident, but it might have been nothing more unusual
than a car crash. The theory that she had been on a secret space
mission - still part of popular mythology outside the USSR - could
be ruled out. Thanks to the global tracking networks, no such thing
had been possible for fifty years.
In addition to her physical and doubtless psychological scars,
Zenia laboured under yet another handicap. She was a last-minute
replacement, and everyone knew it. Irma Yakunina was to have been
dietician and medical assistant aboard Leonov before that
unfortunate argument with a hang-glider broke too many bones.
Every day at 1800 GMT the crew of seven plus one passenger gathered
in the tiny common room that separated the flight deck from the
galley and sleeping quarters. The circular table at its centre was
just big enough for eight people to squeeze around; when Chandra
and Curnow were revived, it would be unable to accommodate
everyone, and two extra seats would have to be fitted in somewhere
else.
Though the 'Six O'Clock Soviet', as the daily round-table
conference was called, seldom lasted more than ten minutes, it
played a vital role in maintaining morale. Complaints, suggestions,
criticisms, progress reports - anything could be raised, subject
only to the captain's overriding veto, which was very seldom
exercised.
Typical items on the non-existent agenda were requests for changes
in the menu, appeals for more private communication time with
Earth, suggested movie programmes, exchange of news and gossip, and
good-natured needling of the heavily-outnumbered American
contingent. Things would change, Floyd warned them, when his
colleagues came out of hibernation, and the odds improved from I in
7 to 3 in 9. He did not mention his private belief that Curnow
could outtalk or outshout any three other people aboard.
When he was not sleeping, much of Floyd's own time was spent in the
common room - partly because, despite its smallness, it was much
less claustrophobic than his own tiny cubicle. It was also
cheerfully decorated, all available flat surfaces being covered
with photos of beautiful land and seascapes, sporting events,
portraits of popular videostars, and other reminders of Earth.
Pride of place, however, was given to an original Leonov painting -
his 1965 study 'Beyond the Moon', made in the same year when, as a
young lieutenant-colonel, he left Voskhod II and became the first
man in history to perform an extravehicular excursions
Clearly the work of a talented amateur, rather than a professional,
it showed the cratered edge of the Moon with the beautiful Sinus
lridum - Bay of Rainbows - in the foreground. Looming monstrously
above the lunar horizon was the thin crescent of Earth, embracing
the darkened nightside of the planet. Beyond that blazed the Sun,
the streamers of the corona reaching out into space for millions of
kilometres around it.
It was a striking composition - and a glimpse of the future that
even then lay only three years ahead. On the flight of Apollo 8,
Anders, Borman and Lovell were to see this splendid sight with
their unaided eyes, as they watched Earth rise above the farside on
Christmas Day, 1968.
Heywood Floyd admired the painting, but he also regarded it with
mixed feelings. He could not forget that it was older than
everybody else on the ship - with one exception.
He was already nine years old when Alexei Leonov had painted
it.
Even now, more than three decades after the revelations of the
first Voyager flybys, no one really understood why the four giant
satellites differed so wildly from one another. They were all about
the same size, and in the same part of the Solar System - yet they
were totally dissimilar, as if children of a different birth.
Only Callisto, the outermost, had turned out to be much as
expected. When Leonov raced past at a distance of just over 100,000
kilometres, the larger of its countless craters were clearly
visible to the naked eye. Through the telescope, the satellite
looked like a glass ball that had been used as a target by
high-powered rifles; it was completely covered with craters of
every size, right down to the lower limit of visibility. Callisto,
someone had once remarked, looked more like Earth's Moon than did
the Moon itself.
Nor was this particularly surprising. One would have expected a
world out here - at the edge of the asteroid belt - to have been
bombarded with the debris left over from the creation of the Solar
System. Yet Ganymede, the satellite next door, had a totally
different appearance. Though it had been well peppered with impact
craters in the remote past, most of them had been ploughed over - a
phrase that seemed peculiarly appropriate. Huge areas of Ganymede
were covered with ridges and furrows, as if some cosmic gardener
had dragged a giant rake across them. And there were light-coloured
streaks, like trails that might have been made by slugs fifty
kilometres across. Most mysterious of all were long, meandering
bands, containing dozens of parallel lines. It was Nikolai
Ternovsky who decided what they must be - multilane superhighways,
laid out by drunken surveyors. He even claimed to have detected
over-passes and cloverleaf intersections.
Leonov had added some trillions of bits of information about
Ganymede to the store of human knowledge, before it crossed the
orbit of Europa. That icebound world, with its derelict and its
dead, was on the other side of Jupiter, but it was never far from
anyone's thoughts.
Back on Earth, Dr Chang was already a hero and his countrymen had,
with obvious embarrassment, acknowledged countless messages of
sympathy. One had been sent in the name of Leonov's crew - after,
Floyd gathered, considerable redrafting in Moscow. The feeling on
board the ship was ambiguous - a mixture of admiration, regret, and
relief. All astronauts, irrespective of their national origins,
regarded themselves as citizens of space and felt a common bond,
sharing each other's triumphs and tragedies. No one on Leonov was
happy because the Chinese expedition had met with disaster; yet at
the same time, there was a muted sense of relief that the race had
not gone to the swiftest.
The unexpected discovery of life on Europa had added a new element
to the situation - one that was now being argued at great length
both on Earth and aboard Leonov. Some exobiologists cried 'I told
you so!', pointing out that it should not have been such a surprise
after all. As far back as the 1970s, research submarines had found
teeming colonies of strange marine creatures thriving precariously
in an environment thought to be equally hostile to life - the
trenches on the bed of the Pacific. Volcanic springs, fertilizing
and warming the abyss, had created oases of life in the deserts of
the deep.
Anything that had happened once on Earth should be expected
millions of times elsewhere in the Universe; that was almost an
article of faith among scientists. Water - or at least ice -
occurred on all the moons of Jupiter. And there were continuously
erupting volcanoes on Io - so it was reasonable to expect weaker
activity on the world next door. Putting these two facts together
made Europan life seem not only possible, but inevitable - as most
of nature's surprises are, when viewed with 20/20 hindsight.
Yet that conclusion raised another question, and one vital to
Leonov's mission. Now that life had been discovered on the moons of
Jupiter - did it have any connection with the Tycho monolith, and
the still more mysterious artifact in orbit near Io?
That was a favourite subject to debate in the Six O'Clock Soviets.
It was generally agreed that the creature encountered by Dr Chang
did not represent a high form of intelligence - at least, if his
interpretation of its behaviour was correct. No animal with even
elementary powers of reasoning would have allowed itself to become
a victim of its instincts, attracted like a moth to the candle
until it risked destruction.
Vasili Orlov was quick to give a counter-example that weakened, if
it did not refute, that argument.
'Look at whales and dolphins,' he said. 'We call them intelligent -
but how often they kill themselves in mass strandings! That looks
like a case where instinct overpowers reason.'
'No need to go to the dolphins,' interjected Max Brailovsky. 'One
of the brightest engineers in my class was fatally attracted to a
blonde in Kiev. When I heard of him last, he was working in a
garage. And he'd won a gold medal for designing spacestations. What
a waste!'
Even if Dr Chang's Europan was intelligent, that of course did not
rule out higher forms elsewhere. The biology of a whole world could
not be judged from a single specimen.
But it had been widely argued that advanced intelligence could
never arise in the sea; there were not enough challenges in so
benign and unvarying an environment. Above all, how could marine
creatures ever develop a technology without the aid of fire?
Yet perhaps even that was possible; the route that humanity had
taken was not the only one. There might be whole civilizations in
the seas of other worlds.
Still, it seemed unlikely that a space-faring culture could have
arisen on Europa without leaving unmistakable signs of its
existence in the form of buildings, scientific installations,
launching sites, or other artifacts. But from pole to pole, nothing
could be seen but level ice and a few outcroppings of bare
rock.
No time remained for speculations and discussions when Leonov
hurtled past the orbits of Io and tiny Mimas. The crew was busy
almost non-stop, preparing for the encounter and the brief onset of
weight after months in free-fall. All loose objects had to be
secured before the ship entered Jupiter's atmosphere, and the drag
of deceleration produced momentary peaks that might be as high as
two gravities.
Floyd was lucky; he alone had time to admire the superb spectacle
of the approaching planet, now filling almost half the sky. Because
there was nothing to give it scale, there was no way that the mind
could grasp its real size. He had to keep telling himself that
fifty Earths would not cover the hemisphere now turned toward
him.
The clouds, colourful as the most garish sunset on Earth, raced so
swiftly that he could see appreciable movement in as little as ten
minutes. Great eddies were continually forming along the dozen or
so bands that girdled the planet, then rippling away like swirls of
smoke. Plumes of white gas occasionally geysered up from the
depths, to be swept away by the gales caused by the planet's
tremendous spin. And perhaps strangest of all were the white spots,
sometimes spaced as regularly as pearls on a necklace, which lay
along the tradewinds of the middle Jovian latitudes.
In the hours immediately before encounter, Floyd saw little of
captain or navigator. The Orlovs scarcely left the bridge, as they
continually checked the approach orbit and made minute refinements
to Leonov's course. The ship was now on the critical path that
would just graze the outer atmosphere; if it went too high,
frictional braking would not be sufficient to slow it down, and it
would go racing out of the Solar System, beyond all possibility of
rescue. If it went too low, it would burn up like a meteor. Between
the two extremes lay little margin for error.
The Chinese had proved that aerobraking could be done, but there
was always the chance that something would go wrong: So Floyd was
not at all surprised when Surgeon-Commander Rudenko admitted, just
an hour before contact: 'I'm beginning to wish, Woody, that I had
brought along that icon, after all.'
'... papers for the mortgage on the Nantucket house should be in
the file marked M in the library.
'Well, that's all the business I can think of. For the last couple
of hours I've been recalling a picture I saw as a boy, in a
tattered volume of Victorian art - it must have been almost one
hundred and fifty years old. I can't remember whether it was
black-and-white or colour. But I'll never forget the title - don't
laugh - it was called "The Last Message Home". Our
great-great-grandfathers loved that kind of sentimental
melodrama.
'It shows the deck of a windjammer in a hurricane - the sails have
been ripped away and the deck's awash. In the background, the crew
is struggling to save the ship. And in the foreground, a young
sailor boy's writing a note, while beside him is the bottle he
hopes will carry it to land.
'Even though I was a kid at the time, I felt he should have been
giving his shipmates a hand, not writing letters. All the same, it
moved me: I never thought that one day I'd be like that young
sailor.
'Of course, I'm sure you'll get this message-and there's nothing I
can do to help aboard Leonov. In fact, I've been politely requested
to keep out of the way, so my conscience is quite clear as I
dictate this.
'I'll send it up to the bridge now because in fifteen minutes we'll
break transmission as we pull in the big dish and batten down the
hatches - there's another nice maritime analogy for you! Jupiter's
filling the sky now - I won't attempt to describe it and won't even
see it much longer because the shutters will go up in a few
minutes. Anyway, the cameras can do far better than I could.
'Goodbye, my dearest, and my love to you all - especially Chris. By
the time you get this, it will be over, one way or the other.
Remember I tried to do my best for all our sakes - goodbye.'
When he had removed the audio chip, Floyd drifted up to the
communications centre and handed it over to Sasha Kovalev.
'Please make sure it gets off before we close down,' he said
earnestly.
'Don't worry,' promised Sasha. 'I'm still working on all channels,
and we have a good ten minutes left.'
He held out his hand. 'If we do meet again, why, we shall smile! If
not, why then, this parting was well made.' Floyd blinked.
'Shakespeare, I suppose?'
'Of course; Brutus and Cassius before battle. See you later.'
Tanya and Vasili were too intent upon their situation displays to
do more than wave to Floyd, and he retreated to his cabin. He had
already said farewell to the rest of the crew; there was nothing to
do but wait. His sleeping bag was slung in preparation for the
return of gravity when deceleration commenced, and he had only to
climb into it - 'Antennas retracted, all protective shields up,'
said the intercom speaker. 'We should feel first braking in five
minutes. Everything normal.'
'That's hardly the word I'd use,' Floyd muttered to himself. 'I
think you mean "nominal".' He had barely concluded the thought when
there was a diffident knock on the door.
'Kto tam?'
To his astonishment, it was Zenia.
'Do you mind if I come in?' she asked awkwardly, in a small-girl
voice which Floyd could scarcely recognize.
'Of course not. But why aren't you in your own cubicle? It's only
five minutes to re-entry.'
Even as he asked the question, he was aware of its foolishness. The
answer was so perfectly obvious that Zenia did not deign to
reply.
But Zenia was the very last person he would have expected: her
attitude toward him had invariably been polite but distant. Indeed,
she was the only member of the crew who preferred to call him Dr
Floyd. Yet there she was, clearly seeking comfort and companionship
at the moment of peril.
'Zenia, my dear,' he said wryly. 'You're welcome. But my
accommodation is somewhat limited. One might even call it
Spartan.'
She managed a faint smile, but said nothing as she floated into the
room. For the first time, Floyd realized that she was not merely
nervous - she was terrified. Then he understood why she had come to
him. She was ashamed to face her countrymen and was looking for
support elsewhere.
With this realization, his pleasure at the unexpected encounter
abated somewhat. That did not lessen his responsibility to another
lonely human being, a long way from home. The fact that she was an
attractive - though certainly not beautiful - woman of barely half
his own age should not have affected the issue. But it did; he was
beginning to rise to the occasion.
She must have noticed, but did nothing to encourage or discourage
him as they lay down side by side in the sleeping cocoon. There was
just enough room for them both, and Floyd began to do some anxious
calculations. Suppose maximum gee was higher than predicted, and
the suspension gave way? They could easily be killed...
There was an ample safety margin; no need to worry about such an
ignominious end. Humour was the enemy of desire; their embrace was
now completely chaste. He was not sure whether to be glad or
sorry.
And it was too late for second thoughts. From far, far away came
the first faint whisper of sound, like the wailing of some lost
soul. At the same moment, the ship gave a barely perceptible jerk;
the cocoon began to swing around and its suspension tightened.
After weeks of weightlessness, gravity was returning.
Within seconds, the faint wail had risen to a steady roar, and the
cocoon had become an overloaded hammock. This is not such a good
idea, Floyd thought to himself, already it was difficult to
breathe. The deceleration was only a part of the problem: Zenia was
clutching him as a drowning person is supposed to clutch the
proverbial straw.
He detached her as gently as he could.
'It's all right, Zenia. If Tsien did it, so can we. Relax - don't
worry.'
It was difficult to shout tenderly, and he was not even sure if
Zenia heard him above the roar of incandescent hydrogen. But she
was no longer clutching him quite so desperately, and he seized the
opportunity of taking a few deep breaths.
What would Caroline think if she could see him now? Would he tell
her if he ever had the chance? He was not sure she would
understand. At a moment like that, all links with Earth seemed very
tenuous indeed.
It was impossible to move, or to speak, but now that he had grown
accustomed to the strange sense of weight he was no longer
uncomfortable - except for the increasing numbness in his right
arm. With some difficulty, he managed to extricate it from beneath
Zenia; the familiar act brought a fleeting sense of guilt. As he
felt his circulation returning, Floyd remembered a famous remark
attributed to at least a dozen astronauts and cosmonauts: 'Both the
pleasures and problems of zero-gravity sex have been greatly
exaggerated.'
He wondered how the rest of the crew was faring, and he gave a
momentary thought to Chandra and Curnow, sleeping peacefully
through it all. They would never know if Leonov became a meteor
shower in the Jovian sky. He did not envy them; they had missed the
experience of a lifetime.
Tanya was speaking over the intercom; her words were lost in the
roar, but her voice sounded calm and perfectly normal, just as if
she was making a routine announcement. Floyd managed to glance at
his watch, and was astonished to see that they were already at the
midpoint of the braking manoeuvre. At that very moment, Leonov was
at its closest approach to Jupiter; only expendable automatic
probes had gone deeper into the Jovian atmosphere.
'Halfway through, Zenia,' he shouted. 'On the way out again.' He
could not tell if she understood. Her eyes were tightly closed, but
she smiled slightly.
The ship was now rocking noticeably, like a small boat in a choppy
sea. Was that normal? wondered Floyd. He was glad that he had Zenia
to worry about; it took his mind away from his own fears. Just for
a moment, before he managed to expel the thought, he had a vision
of the walls suddenly glowing cherry red, and caving in upon him.
Like the nightmare fantasy of Edgar Allan Poe's 'The Pit and the
Pendulum', which he'd forgotten for thirty years.
But that would never happen. If the heat shield failed, the ship
would crumble instantly, hammered flat by a solid wall of gas.
There would be no pain; his nervous system would not have time to
react before it ceased to exist. He had experienced more consoling
thoughts, but this one was not to be despised.
The buffeting slowly weakened. There was another inaudible
announcement from Tanya (he would pull her leg about that, when it
was all over). Now time seemed to be going much more slowly; after
a while he stopped looking at his watch, because he could not
believe it. The digits changed so slowly that he could almost
imagine himself in some Einsteinian time dilation.
And then something even more unbelievable happened. First he was
amused, then slightly indignant. Zenia had fallen asleep - if not
exactly in his arms, then at least beside them.
It was a natural reaction: the strain must have exhausted her, and
the wisdom of the body had come to her rescue. And suddenly Floyd
himself became aware of an almost post-orgasmic drowsiness, as if
he too had been emotionally drained by the encounter. He had to
fight to remain awake.
And then he was falling... falling... falling... it was all over.
The ship was back in space, where it belonged. And he and Zenia
were floating apart.
They would never again be so close together, but they would always
know a special tenderness toward each other, which no one else
could ever share.
When Floyd reached the observation deck - a discreet few minutes
after Zenia - Jupiter already seemed farther away. But that must be
an illusion based on his knowledge, not the evidence of his eyes.
They had barely emerged from the Jovian atmosphere, and the planet
still filled half the sky.
And now they were - as intended - its prisoners. During the last
incandescent hour, they had deliberately jettisoned the excess
speed that could have carried them right out of the Solar System,
and on to the stars. Now they were travelling in an ellipse - a
classical Hohmann orbit - which would shuttle them back between
Jupiter and the orbit of Io, 350,000 kilometres higher. If they did
not - or could not - fire their motors again, Leonov would swing
back and forth between these limits, completing one revolution
every nineteen hours. It would become the closest of Jupiter's
moons - though not for long. Each time it grazed the atmosphere it
would lose altitude, until it spiralled into destruction.
Floyd had never really enjoyed vodka, but he joined the others
without any reservations in drinking a triumphant toast to the
ship's designers, coupled with a vote of thanks to Sir Isaac
Newton. Then Tanya put the bottle firmly back in its cupboard;
there was still much to be done.
Though they were all expecting it, everyone jumped at the sudden
muffled thud of explosive charges, and the jolt of separation. A
few seconds later, a large, still-glowing disk floated into view,
slowly turning end-over-end as it drifted away from the ship.
'Look!' cried Max. 'A flying saucer! Who's got a camera?' There was
a distinct note of hysterical relief in the laughter that followed.
It was interrupted by the captain, in a more serious vein.
'Goodbye, faithful heat shield! You did a wonderful job.'
'But what a waste!' said Sasha. 'There's at least a couple of tons
left, Think of all the extra payload we could have carried!'
'If that's good, conservative Russian engineering,' retorted Floyd,
'then I'm all for it. Far better a few tons too much - than one
milligram too little.'
Everyone applauded those noble sentiments as the jetti soned shield
cooled to yellow, then red, and finally became as black as the
space around it. It vanished from sight while only a few kilometres
away, though occasionally the sudden reappearance of an eclipsed
star would betray its presence.
'Preliminary orbit check completed,' said Vasili. 'We're within ten
metres a second of our right vector. Not bad for a first try.'
There was a subdued sigh of relief at the news, and a few minutes
later Vasili made another announcement.
'Changing attitude for course correction; delta vee six metres a
second. Twenty-second burn coming up in one minute.'
They were still so close to Jupiter it was impossible to believe
that the ship was orbiting the planet; they might have been in a
high-flying aircraft that had just emerged from a sea of clouds.
There was no sense of scale; it was easy to imagine that they were
speeding away from some terrestrial sunset; the reds and pinks and
crimsons sliding below were so familiar.
And that was an illusion; nothing here had any parallels with
Earth. Those colours were intrinsic, not borrowed from the setting
sun. The very gases were utterly alien - methane and ammonia and a
witch's brew of hydrocarbons, stirred in a hydrogen-helium
cauldron. Not one trace of free oxygen, the breath of human
life.
The clouds marched from horizon to horizon in parallel rows,
distorted by occasional swirls and eddies. Here and there
upwellings of brighter gas broke the pattern, and Floyd could also
see the dark rim of a great whirlpool, a maelstrom of gas leading
down into unfathomable Jovian depths.
He began to look for the Great Red Spot, then quickly checked
himself at such a foolish thought. All the enormous cloudscape he
could see below would be only a few per cent of the Red Spot's
immensity; one might as well expect to recognize the shape of the
United States from a small aeroplane flying low above Kansas.
'Correction completed. We're now on interception orbit with Io.
Arrival time: eight hours, fifty-five minutes.'
Less than nine hours to climb up from Jupiter and meet whatever is
waiting for us, thought Floyd. We've escaped from the giant - but
he represents a danger we understood, and could prepare for. What
lies ahead now is utter mystery.
And when we have survived that challenge, we must return to Jupiter
once again. We shall need his strength to send us safely home.
'... Hello, Dimitri. This is Woody, switching to Key Two in fifteen
seconds... Hello, Dimitri - multiply Keys Three and Four, take cube
root, add pi squared and use nearest integer as Key Five. Unless
your computers are a million times faster than ours - and I'm damn
sure they're not - no one can decrypt this, on your side or mine.
But you may have some explaining to do; anyway, you're good at
that.
'By the way, my usual excellent sources told me about the failure
of the latest attempt to persuade old Andrei to resign; I gather
that your delegation had no more luck than the others, and you're
still saddled with him as President. I'm laughing my head off; it
serves the Academy right. I know he's over ninety, and growing a
bit - well, stubborn. But you won't get any help from me, even
though I'm the world's - sorry, Solar System's - leading expert on
the painless removal of elderly scientists.
'Would you believe that I'm still slightly drunk? We felt we
deserved a little party, once we'd successfully rendez -
rendezvous, damn, rendezvoused with Discovery. Besides, we had two
new crew members to welcome aboard. Chandra doesn't believe in
alcohol - it makes you too human - but Walter Curnow more than made
up for him, Only Tanya remained stone-cold sober, just as you'd
expect.
'My fellow Americans - I sound like a politician, God help me -
came out of hibernation without any problems, and are both looking
forward to starting work. We'll all have to move quickly; not only
is time running out, but Discovery seems to be in very bad shape.
We could hardly believe our eyes when we saw how its spotless white
hull had turned a sickly yellow.
'Io's to blame, of course. The ship's spiralled down to within
three thousand kilometres, and every few days one of the volcanoes
blasts a few megatons of sulphur up into the sky. Even though
you've seen the movies, you can't really imagine what it's like to
hang above that inferno; I'll be glad when we can get away, even
though we'll be heading for something much more mysterious - and
perhaps far more dangerous.
'I flew over Kilauea during the '06 eruption; that was mighty
scary, but it was nothing - nothing - compared to this. At the
moment, we're over the nightside, and that makes it worse. You can
see just enough to imagine a lot more. It's as close to Hell as I
ever want to get.
'Some of the sulphur lakes are hot enough to glow, but most of the
light comes from electrical discharges. Every few minutes the whole
landscape seems to explode, as if a giant photoflash has gone off
above it. And that's probably not a bad analogy; there are millions
of amps flowing in the flux-tube linking Io and Jupiter, and every
so often there's a breakdown. Then you get the biggest lightning
flash in the Solar System, and half our circuit-breakers jump out
in sympathy.
'There's just been an eruption right on the terminator, and I can
see a huge cloud expanding up toward us, climbing into the
sunlight. I doubt if it will reach our altitude, and even if it
does it will be harmless by the time it gets here. But it looks
ominous - a space monster, trying to devour us.
'Soon after we got here, I realized that Io reminded me of
something; it took me a couple of days to work it out, and then I
had to check with Mission Archives because the ship's library
couldn't help - shame on it. Do you remember how I introduced you
to The Lord of the Rings, when we were kids back at that Oxford
conference? Well, Io is Mordor: look up Part Three. There's a
passage about "rivers of molten rock that wound their way... until
they cooled and lay like twisted dragon-shapes vomited from the
tormented earth." That's a perfect description: how did Tolkien
know, a quarter century before anyone ever saw a picture of Io?
Talk about Nature imitating Art.
'At least we won't have to land there: I don't think that even our
late Chinese colleagues would have attempted that. But perhaps one
day it may be possible; there are areas that seem fairly stable,
and not continually inundated by sulphur floods.
'Who would have believed that we'd come all the way to Jupiter,
greatest of planets - and then ignore it. Yet that's what we're
doing most of the time; and when we're not looking at Io or
Discovery, we're thinking about the Artifact.
'It's still ten thousand kilometres away, up there at the
libration point, but when I look at it through the main telescope
it seems close enough to touch. Because it's so completely
featureless, there's no indication of size, no way the eye can
judge it's really a couple of kilometres long. If it's solid, it
must weigh billions of tons.
'But is it solid? It gives almost no radar echo, even when it's
square-on to us. We can see it only as a black silhouette against
the clouds of Jupiter, three hundred thousand kilometres below.
Apart from its size, it looks exactly like the monolith we dug up
on the Moon.
'Well, tomorrow we'll go aboard Discovery, and I don't know when
I'll have time or opportunity to speak to you again. But there's
one more thing, old friend, before I sign off.
'It's Caroline. She's never really understood why I had to leave
Earth, and in a way I don't think she'll ever quite forgive me.
Some women believe, that love isn't the only thing - but
everything. Perhaps they're right... anyway, it's certainly too
late to argue now.
'Try and cheer her up when you have a chance. She talks about going
back to the mainland. I'm afraid that if she does...
'If you can't get through to her, try to cheer up Chris. I miss him
more than I care to say.
'He'll believe Uncle Dimitri - if you say that his father still
loves him, and will be coming home just as quickly as he can.'
Even in the best of circumstances, it is not easy to board a
derelict and uncooperative spaceship. Indeed, it can be positively
dangerous.
Walter Curnow knew that as an abstract principle; but he did not
really feel it in his bones until he saw the entire hundred-metre
length of Discovery turning end-over-end, while Leonov kept at a
safe distance. Years ago, friction had braked the spin of
Discovery's carousel, thus transferring its angular momentum to the
rest of the structure. Now, like a drum-majorette's baton at the
height of its trajectory, the abandoned ship was slowly tumbling
along its orbit.
The first problem was to stop that spin, which made Discovery not
only uncontrollable but almost unapproachable. As he suited up in
the airlock with Max Brailovsky, Curnow had a very rare sensation
of incompetence, even inferiority; it was not his line of business.
He had already explained gloomily, 'I'm a space engineer, not a
space monkey'; but the job had to be done. He alone possessed the
skills that could save Discovery from Io's grasp. Max and his
colleagues, working with unfamiliar circuit diagrams and equipment,
would take far too long. By the time they had restored power to the
ship and mastered its controls, it would have plunged into the
sulphurous firepits below.
'You're not scared, are you?' asked Max, when they were about to
put on their helmets.
'Not enough to make a mess in my suit. Otherwise, yes.' Max
chuckled. 'I'd say that's about right for this job. But don't worry
- I'll get you there in one piece, with my - what do you call
it?'
'Broomstick. Because witches are supposed to ride them.'
'Oh yes. Have you ever used one?'
'I tried once, but mine got away from me. Everyone else thought it
was very funny.'
There are some professions which have evolved unique and
characteristic tools - the longshoreman's hook, the potter's wheel,
the bricklayer's trowel, the geologist's hammer. The men who had to
spend much of their time on zero-gravity construction projects had
developed the broomstick.
It was very simple - a hollow tube just a metre long, with a
footpad at one end and a retaining loop at the other. At the touch
of a button, it could telescope out to five or six times its normal
length, and the internal shock-absorbing system allowed a skilled
operator to perform the most amazing manoeuvres. The footpad could
also become a claw or hook if necessary; there were many other
refinements, but that was the basic design. It looked deceptively
easy to use; it wasn't.
The airlock pumps finished recycling; the EXIT sign came on; the
outer doors opened, and they drifted slowly into the void.
Discovery was windmilling about two hundred metres away, following
them in orbit around Io, which filled half the sky. Jupiter was
invisible, on the other side of the satellite. This was a matter of
deliberate choice; they were using Io as a shield to protect them
from the energies raging back and forth in the flux-tube that
linked the two worlds. Even so, the radiation level was dangerously
high; they had less than fifteen minutes before they must get back
to shelter.
Almost immediately, Curnow had a problem with his suit. 'It fitted
me when I left Earth,' he complained. 'But now I'm rattling around
inside like a pea in a pod.'
'That's perfectly normal, Walter,' said Surgeon-Commander Rudenko,
breaking into the radio circuit. 'You lost ten kilos in
hibernation, which you could very well afford to miss. And you've
already put three of them back.'
Before Curnow had time to think of a suitable retort, he found
himself gently but firmly jerked away from Leonov.
'Just relax, Walter,' said Brailovsky. 'Don't use your thrusters,
even if you start tumbling. Let me do all the work.'
Curnow could see the faint puffs from the younger man's backpack,
as its tiny jets drove them toward Discovery. With each little
cloud of vapour there came a gentle tug on the towline, and he
would start moving toward Brailovsky; but he never caught up with
him before the next puff came. He felt rather like a yo-yo - now
making one of its periodic comebacks on Earth - bouncing up and
down on its string.
There was only one safe way to approach the derelict, and that was
along the axis around which it was slowly revolving. Discovery's
centre of rotation was approximately amidships, near the main
antenna complex, and Brailovsky was heading directly toward this
area, with his anxious partner in tow. How will he stop both of us
in time? Curnow asked himself.
Discovery was now a huge, slender dumbbell slowly flailing the
entire sky ahead of them. Though it took several minutes to
complete one revolution, the far ends were moving at an impressive
speed. Curnow tried to ignore them, and concentrated on the
approaching - and immobile - centre.
'I'm aiming for that,' said Brailovsky. 'Don't try to help, and
don't be surprised at anything that happens.'
Now, what does he mean by that? Curnow asked himself, while
preparing to be as unsurprised as possible.
Everything happened in about five seconds. Brailovsky triggered his
broomstick, so that it telescoped out to its full length of four
metres and made contact with the approaching ship. The broomstick
started to collapse, its internal spring absorbing Brailovsky's
considerable momentum; but it did not, as Curnow had fully
expected, bring him to rest beside the antenna mount. It
immediately expanded again, reversing the Russian's velocity so
that he was, in effect, reflected away from Discovery just as
rapidly as he had approached. He flashed past Curnow, heading out
into space again, only a few centimetres away. The startled
American just had time to glimpse a large grin before Brailovsky
shot past him.
A second later, there was a jerk on the line connecting them, and a
quick surge of deceleration as they shared momentum. Their opposing
velocities had been neatly cancelled; they were virtually at rest
with respect to Discovery. Curnow had merely to reach out to the
nearest handhold, and drag them both in.
'Have you ever tried Russian roulette?' he asked, when he had got
his breath back.
'No - what is it?'
'I must teach you sometime. It's almost as good as this for curing
boredom.'
'I hope you're not suggesting, Walter, that Max would do anything
dangerous?'
Dr Rudenko sounded as if she was genuinely shocked, and Curnow
decided it was best not to answer; sometimes the Russians did not
understand his peculiar sense of humour. 'You could have fooled
me,' he muttered under his breath, not loud enough for her to
hear.
Now that they were firmly attached to the hub of the windmilling
ship, he was no longer conscious of its rotation - especially when
he fixed his gaze upon the metal plates immediately before his
eyes. The ladder stretching away into the distance, running along
the slender cylinder that was Discovery's main structure, was his
next objective. The spherical command module at its far end seemed
several light-years away, though he knew perfectly well that the
distance was only fifty metres.
'I'll go first,' said Brailovsky, reeling in the slack on the line
linking them together. 'Remember - it's downhill all the way from
here. But that's no problem - you can hold on with one hand. Even
at the bottom, gravity's only about a tenth gee. And that's - what
do you say? - chickenshit.'
'I think you mean chickenfeed. And if it's all the same to you, I'm
going feet first. I never liked crawling down ladders the wrong way
up - even in fractional gravity.'
It was essential, Curnow was very well aware, to keep up this
gently bantering tone; otherwise he would be simply overwhelmed by
the mystery and danger of the situation. There he was, almost a
billion kilometres from home, about to enter the most famous
derelict in the entire history of space exploration; a media
reporter had once called Discovery the Marie Celeste of space, and
that was not a bad analogy. But there was also much that made his
situation unique; even if he tried to ignore the nightmare
moonscape filling half the sky, there was a constant reminder of
its presence at hand. Every time he touched the rungs of the
ladder, his glove dislodged a thin mist of sulphur dust.
Brailovsky, of course, was quite correct; the rotational gravity
caused by the ship's end-over-end tumbling was easily countered. As
he grew used to it, Curnow even welcomed the sense of direction it
gave him.
And then, quite suddenly, they had reached the big, discoloured
sphere of Discovery's control and life-support module. Only a few
metres away was an emergency hatch - the very one, Curnow realized,
that Bowman had entered for his final confrontation with Hal.
'Hope we can get in,' muttered Brailovsky. 'Pity to come all this
way and find the door locked.'
He scraped away the sulphur obscuring the AIRLOCK STATUS display
panel.
'Dead, of course. Shall I try the controls?'
'Won't do any harm - but nothing will happen.'
'You're right. Well, here goes with manual...
It was fascinating to watch the narrow hairline open in the curved
wall, and to note the little puff of vapour dispersing into space,
carrying with it a scrap of paper. Was that some vital message?
They would never know; it spun away, tumbling end over end without
losing any of its initial spin as it disappeared against the
stars.
Brailovsky kept turning the manual control for what seemed a very
long time, before the dark, uninviting cave of the airlock was
completely open. Curnow had hoped that the emergency lights, at
least, might still be operating. No such luck.
'You're boss now, Walter. Welcome to US territory.'
It certainly did not look very welcoming as he clambered inside,
flashing the beam of his helmet light around the interior. As far
as Curnow could tell, everything was in good order. What else had
he expected? he asked himself, half angrily.
Closing the door manually took even longer than opening it, but
there was no alternative until the ship was powered up again. Just
before the hatch was sealed, Curnow risked a glance at the insane
panorama outside.
A flickering blue lake had opened up near the equator; he was sure
it had not been there a few hours earlier. Brilliant yellow flares,
the characteristic colour of glowing sodium, were dancing along its
edges; and the whole of the nightland was veiled in the ghostly
plasma discharge of one of Io's almost continuous auroras.
It was the stuff of future nightmares - and as if that was not
sufficient, there was one further touch worthy of a mad surrealist
artist. Stabbing up into the black sky, apparently emerging
directly from the firepits of the burning moon, was an immense,
curving horn, such as a doomed bullfighter might have glimpsed in
the final moment of truth.
The crescent of Jupiter was rising to greet Discovery and Leonov as
they swept toward it along their common orbit.
The moment that the outer hatch had closed behind them, there had
been a subtle reversal of roles. Curnow was at home now, while
Brailovsky was out of his element, feeling ill at ease in the
labyrinth of pitch-black corridors and tunnels that was Discovery's
interior. In theory, Max knew his way round the ship, but that
knowledge was based only on a study of its design drawings. Curnow,
on the other hand, had spent months working in Discovery's still
uncompleted identical twin; he could, quite literally, find his way
around blindfolded.
Progress was made difficult because that part of the ship was
designed for zero gee; now the uncontrolled spin provided an
artificial gravity, which, slight though it was, always seemed to
be in the most inconvenient direction.
'First thing we've got to do,' muttered Curnow, after sliding
several metres down a corridor before he could grab a handhold, 'is
to stop this damned spin. And we can't do that until we have power.
I only hope that Dave Bowman safeguarded all systems before he
abandoned ship.'
'Are you sure he did abandon the ship? He may have intended to come
back.'
'You may be right; I don't suppose we'll ever know. If he even knew
himself.'
They had now entered the Pod Bay - Discovery's 'space garage',
which normally contained three of the spherical one-man modules
used for activities outside the ship. Only Pod Number 3 remained;
Number 1 had been lost in the mysterious accident that had killed
Frank Poole - and Number 2 was with Dave Bowman, wherever he might
be.
The Pod Bay also contained two spacesuits, looking uncomfortably
like decapitated corpses as they hung helmet-less in their racks.
It needed very little effort of the imagination - and Brailovsky's
was now working overtime - to fill them with a whole menagerie of
sinister occupants.
It was unfortunate, but not altogether surprising, that Curnow's
sometimes irresponsible sense of humour got the better of him at
this very moment.
'Max,' he said, in a tone of deadly seriousness, 'whatever happens
- please don't go chasing off after the ship's cat.'
For a few milliseconds, Brailovsky was thrown off guard; he almost
answered: 'I do wish you hadn't said that, Walter', but checked
himself in time. That would have been too damning an admission of
weakness; instead he replied, 'I'd like to meet the idiot who put
that movie in our library.'
'Katerina probably did it, to test everyone's psychological
balance. Anyway, you laughed your head off when we screened it last
week.'
Brailovsky was silent; Curnow's remark was perfectly true. But that
had been back in the familiar warmth and light of Leonov, among his
friends - not in a pitch-black, freezing derelict, haunted by
ghosts. No matter how rational one was, it was all too easy to
imagine some implacable alien beast prowling these corridors,
seeking whom it might devour.
It's all your fault, Grandma (may the Siberian tundra lie lightly
on your beloved bones) - I wish you hadn't filled my mind with so
many of those gruesome legends. If I close my eyes, I can still see
the hut of the Baba Yaga, standing in that forest clearing on its
scrawny chicken legs...
Enough of this nonsense. I'm a brilliant young engineer faced with
the biggest technical challenge of his life, and I mustn't let my
American friend know that I'm sometimes a frightened little
boy.
The noises did not help. There were too many of them, though they
were so faint that only an experienced astronaut would have
detected them against the sounds of his own suit. But to Max
Brailovsky, accustomed to working in an environment of utter
silence, they were distinctly unnerving, even though he knew that
the occasional cracklings and creakings were almost certainly
caused by thermal expansion as the ship turned like a roast on a
spit. Feeble though the sun was out here, there was still an
appreciable temperature change between light and shade.
Even his familiar spacesuit felt wrong, now that there was pressure
outside as well as in. All the forces acting on its joints were
subtly altered, and he could no longer judge his movements
accurately. I'm a beginner, starting my training all over again, he
told himself angrily. Time to break the mood by some decisive
action.
'Walter - I'd like to test the atmosphere.'
'Pressure's okay; temperature - phew - it's one hundred five below
zero.'
'A nice bracing Russian winter. Anyway, the air in my suit will
keep out the worst of the cold.'
'Well, go ahead. But let me shine my light on your face, so I can
see if you start to turn blue. And keep talking.'
Brailovsky unsealed his visor and swung the faceplate upward. He
flinched momentarily as icy fingers seemed to caress his cheeks,
then took a cautious sniff, followed by a deeper breath.
'Chilly - but my lungs aren't freezing. There's a funny smell,
though. Stale, rotten - as if something's - oh no!'
Looking suddenly pale, Brailovsky quickly snapped the faceplate
shut.
'What's the trouble, Max?' Curnow asked with sudden and now
perfectly genuine anxiety. Brailovsky did not reply; he looked as
if he was still trying to regain control of himself. Indeed, he
seemed in real danger of that always horrible and sometimes fatal
disaster - vomiting in a spacesuit.
There was a long silence; then Curnow said reassuringly:
'I get it. But I'm sure you're wrong. We know that Poole was lost
in space. Bowman reported that he... ejected the others after they
died in hibernation - and we can be sure that he did. There can't
be anyone here. Besides, it's so cold.' He almost added 'like a
morgue' but checked himself in time.
'But' suppose,' whispered Brailovsky, 'just suppose Bowman managed
to get back to the ship - and died here.'
There was an even longer silence before Curnow deliberately and
slowly opened his own faceplate. He winced as the freezing air bit
into his lungs, then wrinkled his nose in disgust.
'I see what you mean. But you're letting your imagination run away
with you. I'll bet you ten to one that smell comes from the galley.
Probably some meat went bad, before the ship froze up. And Bowman
must have been too busy to be a good housekeeper. I've known
bachelor apartments that smelled as bad as this.'
'Maybe you're right. I hope you are.'
'Of course I am. And even if I'm not - dammit, what difference does
it make? We've got a job to do, Max. If Dave Bowman's still here,
that's not our department - is it, Katerina?'
There was no reply from the Surgeon-Commander; they had gone too
far inside the ship for radio to penetrate. They were indeed on
their own, but Max's spirits were rapidly reviving. It was a
privilege, he decided, to work with Walter. The American engineer
sometimes appeared soft and easygoing. But he was totally competent
- and, when necessary, as hard as nails.
Together, they would bring Discovery back to life; and, perhaps,
back to Earth.
When Discovery suddenly lit up like the proverbial Christmas tree,
navigation and interior lights blazing from end to end, the cheer
aboard Leonov might almost have been heard across the vacuum
between the two ships. It turned into an ironic groan when the
lights promptly went out again.
Nothing else happened for half an hour; then the observation
windows of Discovery's flight deck began to glow with the soft
crimson of the emergency lights. A few minutes later, Curnow and
Brailovsky could be seen moving around inside, their figures
blurred by the film of sulphur dust.
'Hello, Max - Walter - can you hear us?' called Tanya Orlova. Both
the figures waved instantly, but made no other reply. Obviously,
they were too busy to engage in casual conversation; the watchers
on Leonov had to wait patiently while various lights flashed on and
off, one of the three Pod Bay doors slowly opened and quickly
closed, and the main antenna slewed around a modest ten
degrees.
'Hello, Leonov,' said Curnow at last. 'Sorry to keep you waiting,
but we've been rather busy.
'Here's a quick assessment, judging from what we've seen so far.
The ship's in much better shape than I feared. Hull's intact,
leakage negligible - air pressure eighty-five per cent nominal.
Quite breathable, but we'll have to do a major recycling job
because it stinks to high heaven.
'The best news is that the power systems are okay. Main reactor
stable, batteries in good shape. Almost all the circuit-breakers
were open - they'd jumped or been thrown by Bowman before he left -
so all vital equipment's been safeguarded. But it will be a very
big job checking everything before we have full power again.'
'How long will that take - at least for the essential systems:
life-support, propulsion?'
'Hard to say, skipper. How long before we crash?'
'Minimum present prediction is ten days. But you know how that's
changed up - and down.'
'Well, if we don't run into any major snags, we can haul Discovery
up to a stable orbit away from this hellhole - oh, I'd say inside a
week.'
'Anything you need?'
'No - Max and I are doing fine. We're going into the carousel now,
to check the bearings. I want to get it running as soon as
possible.'
'Pardon me, Walter - but is that important? Gravity's convenient,
but we've managed without any for quite a while.'
'I'm not after gravity, though it will be useful to have some
aboard. If we can get the carousel running again, it will mop up
the ship's spin - stop it tumbling. Then we'll be able to couple
our airlocks together, and cut out EVAs. That will make work a
hundred times easier.'
'Nice idea, Walter - but you're not going to mate my ship to
that... windmill. Suppose the bearings seize up and the carousel
jams? That would tear us to pieces.'
'Agreed. We'll cross that bridge when we come to it. I'll report
again as soon as I can.'
No one had much rest for the next two days. By the end of that
time, Curnow and Brailovsky had practically fallen asleep in their
suits, but had completed their survey of Discovery and found no
unpleasant surprises. Both the Space Agency and the State
Department were relieved by the preliminary report; it allowed them
to claim, with some justification, that Discovery was not a
derelict but a 'temporarily decommissioned United States
Spacecraft'. Now the task of reconditioning had to begin.
Once power had been restored, the next problem was the air; even
the most thorough housecleaning operations had failed to remove the
stink. Curnow had been right in identifying its source as food
spoiled when refrigeration had failed; he also claimed, with mock
seriousness, that it was quite romantic. 'I've only got to close my
eyes,' he asserted, 'and I feel I'm back on an old-time whaling
ship. Can you imagine what the Pequod must have smelled like?'
It was unanimously agreed that, after a visit to Discovery, very
little effort of the imagination was required. The problem was
finally solved - or at least reduced to manageable proportions - by
dumping the ship's atmosphere. Fortunately, there was still enough
air in the reserve tanks to replace it.
One piece of very welcome news was that ninety per cent of the
propellant needed for the return journey was still available;
choosing ammonia instead of hydrogen as working fluid for the
plasma drive had paid off handsomely. The more efficient hydrogen
would have boiled off into space years ago, despite the insulation
of the tanks and the frigid temperature outside. But almost all the
ammonia had remained safely liquified, and there was enough to get
the ship back to a safe orbit around the Earth. Or at least around
the Moon.
Checking Discovery's propellerlike spin was perhaps the most
critical step in getting the ship under control. Sasha Kovalev
compared Curnow and Brailovsky to Don Quixote and Sancho Panza, and
expressed the hope that their windmill-tilting expedition would end
more successfully.
Very cautiously, with many pauses for checking, power was fed to
the carousel motors and the great drum was brought up to speed,
reabsorbing the spin it had long ago imparted to the ship.
Discovery executed a complex series of precessions, until
eventually its end-over-end tumble had almost vanished. The last
traces of unwanted rotation were neutralized by the
attitude-control jets, until the two ships were floating motionless
side by side, the squat, stocky Leonov dwarfed by the long, slender
Discovery.
Transfer from one to the other was now safe and easy, but Captain
Orlova still refused to permit a physical linkup. Everyone agreed
with this decision, for Io was coming steadily closer; they might
yet have to abandon the vessel they had worked so hard to save.
The fact that they now knew the reason for Discovery's mysterious
orbital decay did not help in the least. Every time the ship passed
between Jupiter and Io, it sliced through the invisible flux-tube
linking the two bodies - the electric river flowing from world to
world. The resulting eddy currents induced in the ship were
continually slowing it down, braking it once every revolution.
There was no way to predict the final moment of impact, for the
current in the flux-tube varied wildly according to Jupiter's own
inscrutable laws. Sometimes there were dramatic surges of activity
accompanied by spectacular electric and auroral storms around Io.
Then the ships would lose altitude by many kilometres, at the same
time becoming uncomfortably hot before their thermal control
systems could readjust.
This unexpected effect had scared and surprised everyone before the
obvious explanation was realized. Any form of braking produces
heat, somewhere; the heavy currents induced in the hulls of Leonov
and Discovery turned them briefly into low-powered electric
furnaces. It was not surprising that some of Discovery's food
supply had been ruined during the years the ship had been
alternately cooked and cooled.
The festering landscape of Io, looking more than ever like an
illustration from a medical textbook, was only five hundred
kilometres away when Curnow risked activating the main drive, while
Leonov stood off at a very respectful distance. There were no
visible effects - none of the smoke and fire of the old-time
chemical rockets - but the two ships drew slowly apart as Discovery
gained speed. After a few hours of very gentle manoeuvring, both
ships had raised themselves a thousand kilometres; now there was
time to relax briefly, and to make plans for the next stage in the
mission.
'You've done a wonderful job, Walter,' said Surgeon-Commander
Rudenko, putting her ample arm around the exhausted Curnow's
shoulders. 'We're all proud of you.'
Very casually, she broke a small capsule under his nose. It was
twenty-four hours before he woke up, annoyed and hungry.
'What is it?' asked Curnow with mild distaste, hefting the little
mechanism in his hand. 'A guillotine for mice?'
'Not a bad description - but I'm after bigger game.' Floyd pointed
to a flashing arrow on the display screen, which was now showing a
complicated circuit diagram.
'You see this line?'
'Yes - the main power supply. So?'
'This is the point where it enters Hal's central processing unit.
I'd like you to install this gadget here. Inside the cable
trunking, where it can't be found without a deliberate search.'
'I see. A remote control, so you can pull the plug on Hal whenever
you want to. Very neat - and a non-conducting blade, too, so there
won't be any embarrassing shorts when it's triggered. Who makes
toys like this? The CIA?'
'Never mind. The control's in my room - that little red calculator
I always keep on my desk. Put in nine nines, take the square root,
and press TNT. That's all. I'm not sure of its range - we'll have
to test that - but as long as Leonov and Discovery are within a
couple of kilometres of each other, there'll be no danger of Hal
running amok again.'
'Who are you going to tell about this... thing?'
'Well, the only person I'm really hiding it from is Chandra.'
'I guessed as much.'
'But the fewer who know, the less likely it is to be talked about.
I'll tell Tanya that it exists, and if there's an emergency you can
show her how to operate it.'
'What kind of emergency?'
'That's not a very bright question, Walter. If I knew, I wouldn't
need the damn thing.'
'Guess you're right. When do you want me to install your patented
Hal-zapper?'
'As soon as you can. Preferably tonight. When Chandra's
sleeping.'
'Are you kidding? I don't think he ever sleeps. He's like a mother
nursing a sick baby.'
'Well, he's got to come back to Leonov to eat, occasionally.'
'I've news for you. The last time he went across, he tied a little
sack of rice to his suit. That will keep him going for weeks.'
'Then we'll have to use one of Katerina's famous knockout drops.
They did a pretty good job on you, didn't they?'
Curnow was joking about Chandra - at least, Floyd assumed that he
was, though one could never be quite sure: he was fond of making
outrageous statements with a perfectly straight face. It had been
some time before the Russians had fully realized that; soon, in
self-defence, they were prone to pre-emptive laughs even when
Curnow was being perfectly serious.
Curnow's own laugh, mercifully, had much abated since Floyd had
first heard it in the upward-bound shuttle; on that occasion, it
had obviously been primed by alcohol. He had fully expected to
cringe from it again at the end-of-orbit party, when Leonov had
finally made rendezvous with Discovery. But even on that occasion,
though Curnow had drunk a good deal, he had remained as much under
control as Captain Orlova herself.
The one thing he did take seriously was his work. On the way up
from Earth, he had been a passenger. Now he was crew.
We are, Floyd told himself, about to awaken a sleeping giant. How
will Hal react to our presence, after all these years? What will he
remember of the past - and will he be friendly, or hostile?
As he floated just behind Dr Chandra in the zero-gravity
environment of Discovery's flight deck, Floyd's mind was seldom far
from the cut-off switch, installed and tested only a few hours
earlier. The radio control was mere centimetres from his hand, and
he felt somewhat foolish to have brought it with him. At this
stage, Hal was still disconnected from all the ship's operational
circuits. Even if he was reactivated, he would be a brain without
limbs though not without sense organs. He would be able to
communicate, but not to act. As Curnow had put it, 'The worst he
can do is swear at us.'
'I'm ready for the first test, Captain,' said Chandra. 'All the
missing modules have been replaced, and I've run diagnostic
programs on all circuits. Everything appears normal, at least on
this level.'
Captain Orlova glanced at Floyd, who gave a nod. At Chandra's
insistence, only the three of them were present for this critical
first run, and it was quite obvious that even this small audience
was unwelcome.
'Very well, Dr Chandra.' Ever conscious of protocol, the captain
added quickly: 'Dr Floyd has given his approval, and I have no
objections myself.'
'I should explain,' said Chandra, in a tone that clearly conveyed
disapproval, 'that his voice-recognition and speech-synthesis
centres have been damaged. We'll have to teach him to speak all
over again. Luckily, he learns several million times faster than a
human being.'
The scientist's fingers danced over the keyboard as he typed out a
dozen words, apparently at random, carefully pronouncing each one
as it appeared on the screen. Like a distorted echo, the words came
back from the speaker grille - lifeless, indeed mechanical, with no
sense of any intelligence behind them. This isn't the old Hal,
thought Floyd. It's no better than the primitive speaking toys that
were such a novelty when I was a kid.
Chandra pressed the REPEAT button, and the series of words sounded
once again. Already, there was a noticeable improvement, though no
one could have mistaken the speaker for a human being.
'The words I gave him contain the basic English phonemes; about ten
iterations, and he'll be acceptable. But I don't have the equipment
to do a really good job of therapy.'
'Therapy?' asked Floyd. 'You mean that 'he's - well,
brain-damaged?'
'No,' snapped Chandra. 'The logic circuits are in perfect
condition. Only the voice output may be defective, though it will
improve steadily. So check everything against the visual display,
to avoid misinterpretations. And when you do speak, enunciate
carefully.'
Floyd gave Captain Orlova a wry smile, and asked the obvious
question.
'What about all the Russian accents around here?'
'I'm sure that won't be a problem with Captain Orlova and Dr
Kovalev. But with the others - well, we'll have to run individual
tests. Anyone who can't pass will have to use the keyboard.'
'That's still looking a long way ahead. For the present, you're the
only person who should attempt communication. Agreed, Captain?'
'Absolutely.'
Only the briefest of nods revealed that Dr Chandra had heard them.
His fingers continued to fly over the keyboard, and columns of
words and symbols flashed across the display screen at such a rate
that no human being could possibly assimilate them. Presumably
Chandra had an eidetic memory, for he appeared to recognize whole
pages of information at a glance.
Floyd and Orlova were just about to leave the scientist to his
arcane devotions when he suddenly acknowledged their presence
again, holding up his hand in warning or anticipation. With an
almost hesitant movement, in marked contrast with his previous
swift actions, he slid back a locking bar and pressed a single,
isolated key.
Instantly, with no perceptible pause, a voice came from the
console, no longer in a mechanical parody of human speech. There
was intelligence - consciousness - self-awareness here, though as
yet only on a rudimentary level.
'Good morning, Dr Chandra, This is Hal. I am ready for my first
lesson.'
There was a moment of shocked silence; then, acting on the same
impulse, the two observers left the deck.
Heywood Floyd would never have believed it. Dr Chandra was
crying.
'... What delightful news about the baby dolphin! I can just
imagine how excited Chris was when the proud parents brought it
into the house. You should have heard the ohs and ahs of my
shipmates when they saw the videos of them swimming together, and
Chris riding on its back. They suggest we call it Sputnik, which
means companion as well as satellite.
'Sorry it's been quite a while since my last message, but the
newscasts will have given you an idea of the huge job we've had to
do. Even Captain Tanya's given up all pretence of a regular
schedule; each problem has to be fixed as it comes along, by
whoever is on the spot. We sleep when we can't stay awake any
longer.
'I think we can all be proud of what we've done. Both ships are
operational and we've nearly finished our first round of tests on
Hal. In a couple of days we'll know if we can trust him to fly
Discovery when we leave here to make our final rendezvous with Big
Brother.
'I don't know who first gave it that name - the Russians,
understandably, aren't keen on it. And they've waxed quite
sarcastic about our official designation TMA-2, pointing out to me
- several times - that it's the best part of a billion kilometres
from Tycho. Also that Bowman reported no magnetic anomaly, and that
the only resemblance to TMA-1 is the shape. When I asked them what
name they preferred, they came up with Zagadka, which means enigma.
It's certainly an excellent name; but everyone smiles when I try to
pronounce it, so I'll stick to Big Brother.
'Whatever you call the thing, it's only ten thousand kilometres
away now, and the trip won't take more than a few hours. But that
last lap has us all nervous, I don't mind telling you.
'We'd hoped that we might find some new information aboard
Discovery. That's been our only disappointment, though we should
have expected it. Hal, of course, was disconnected long before the
encounter, and so has no memories of what happened; Bowman has
taken all his secrets with him. There's nothing in the ship's log
and automatic recording systems that we didn't already know.
'The only new item we discovered was purely personal - a message
that Bowman had left for his mother. I wonder why he never sent it;
obviously, he did expect - or hope - to return to the ship after
that last EVA. Of course, we've had it forwarded to Mrs Bowman -
she's in a nursing home, somewhere in Florida, and her mental
condition is poor, so it may not mean anything to her.
'Well, that's all the news this time. I can't tell you how much I
miss you... and the blue skies and green seas of Earth. All the
colours here are reds and oranges and yellows - often as beautiful
as the most fantastic sunset, but after a while one grows sick for
the cool, pure rays at the other end of the spectrum.
'My love to you both - I'll call again just as soon as I can.'
Nikolai Temovsky, Leonov's control and cybernetics expert, was the
only man aboard who could talk to Dr Chandra on something like his
own terms. Although Hal's principal creator and mentor was
reluctant to admit anyone into his full confidence, sheer physical
exhaustion had forced him to accept help. Russian and Indo-American
had formed a temporary alliance, which functioned surprisingly
well. Most of the credit for this went to the good-natured Nikolai,
who was somehow able to sense when Chandra really needed him, and
when he preferred to be alone. The fact that Nikolai's English was
much the worst on the ship was totally unimportant, since most of
the time both men spoke a computerese wholly unintelligible to
anyone else.
After a week's slow and careful reintegration, all of Hal's
routine, supervisory functions were operating reliably. He was like
a man who could walk, carry out simple orders, do unskilled jobs,
and engage in low-level conversation. In human terms, he had an
Intelligence Quotient of perhaps 50; only the faintest outlines of
his original personality had yet emerged.
He was still sleepwalking; nevertheless, in Chandra's expert
opinion, he was now quite capable of flying Discovery from its
close orbit around Io up to the rendezvous with Big Brother.
The prospect of getting an extra seven thousand kilometres away
from the burning hell beneath them was welcomed by everyone.
Trivial though that distance was in astronomical terms, it meant
that the sky would no longet be dominated by a landscape that might
have been imagined by Dante or Hieronymus Bosch. And although not
even the most violent eruptions had blasted any material up to the
ships, there was always the fear that Io might attempt to set a new
record. As it was, visibility from Leonov's observation deck was
steadily degraded by a thin film of sulphur, and sooner or later
someone would have to go out and clean it off.
Only Curnow and Chandra were aboard Discovery when Hal was given
the first control of the ship. It was a very limited form of
control; he was merely repeating the program that had been fed into
his memory, and monitoring its execution. And the human crew was
monitoring him: if any malfunction occurred, they would take over
immediately.
The first burn lasted for ten minutes; then Hal reported that
Discovery had entered the transfer orbit. As soon as Leonov's radar
and optical tracking confirmed that, the other ship injected itself
into the same trajectory. Two minor in-course corrections were
made; then, three hours and fifteen minutes later, both arrived
uneventfully at the first Lagrange point, L. 1 - 10,500 kilometres
up, on the invisible line connecting the centres of Io and
Jupiter.
Hal had behaved impeccably, and Chandra showed unmistakable traces
of such purely human emotions as satisfaction and even joy. But by
that time, everyone's thoughts were elsewhere; Big Brother, alias
Zagadka, was only a hundred kilometres away.
Even from that distance, it already appeared larger than the Moon
as seen from Earth, and shockingly unnatural in its straight-edged,
geometrical perfection. Against the background of space it would
have been completely invisible, but the scudding Jovian clouds
350,000 kilometres below showed it up in dramatic relief. They also
produced an illusion that, once experienced, the mind found almost
impossible to refute. Because there was no way in which its real
location could be judged by the eye, Big Brother often looked like
a yawning trapdoor set in the face of Jupiter.
There was no reason to suppose that a hundred kilometres would be
'safer than ten, or more dangerous than a thousand; it merely
seemed psychologically right for a first reconnaissance. From that
distance, the ship's telescopes could have revealed details only
centimetres across -but there were none to be seen. Big Brother
appeared completely featureless; which, for an object that had,
presumably, survived millions of years of bombardment by space
debris, was incredible.
When Floyd stared through the binocular eyepiece, it seemed to him
that he could reach out and touch those smooth, ebon surfaces -
just as he had done on the Moon, years ago. That first time, it had
been with the gloved hand of his spacesuit. Not until the Tycho
monolith had been enclosed in a pressurized dome had he been able
to use his naked hand.
That had made no difference; he did not feel that he had ever
really touched TMA-1. The tips of his fingers had seemed to skitter
over an invisible barrier, and the harder he pushed, the greater
the repulsion grew. He wondered if Big Brother would produce the
same effect.
Yet before they came that close, they had to make every test they
could devise and report their observations to Earth. They were in
much the same position as explosives experts trying to defuse a new
type of bomb, which might be detonated by the slightest false move.
For all that they could tell, even the most delicate of radar
probes might trigger some unimaginable catastrophe.
For the first twenty-four hours, they did nothing except observe
with passive instruments - telescopes, cameras, sensors on every
wavelength. Vasili Orlov also took the opportunity of measuring the
slab's dimensions with the greatest possible precision, and
confirmed the famous 1:4:9 ratio to six decimal places. Big Brother
was exactly the same shape as TMA-1 - but as it was more than two
kilometres long, it was 718 times larger than its small
sibling.
And there was a second mathematical mystery. Men had been arguing
for years over that 1:4:9 ratio - the squares of the first three
integers. That could not possibly be a coincidence; now here was
another number to conjure with.
Back on Earth, statisticians and mathematical physicists were soon
playing happily with their computers, trying to relate the ratio to
the fundamental constants of nature - the velocity of light, the
proton/electron mass ratio, the fine-structure constant. They were
quickly joined by a gaggle of numerologists, astrologers, and
mystics, who threw in the height of the Great Pyramid, the diameter
of Stonehenge, the azimuth bearings of the Nazca lines, the
latitude of Easter Island, and a host of other factors from which
they were able to draw the most amazing conclusions about the
future. They were not in the least deterred when a celebrated
Washington humorist claimed that his calculations proved that the
world ended on 31 December 1999 - but that everyone had had too
much of a hangover to notice.
Nor did Big Brother appear to notice the two ships that had arrived
in its vicinity - even when they cautiously probed it with radar
beams and bombarded it with strings of radio pulses which, it was
hoped, would encourage any intelligent listener to answer in the
same fashion.
After two frustrating days, with the approval of Mission Control,
the ships halved their distance. From fifty kilometres, the largest
face of the slab appeared about four times the width of the Moon in
Earth's sky - impressive, but not so large as to be psychologically
overwhelming. It could not yet compete with Jupiter, ten times
larger still; and already the mood of the expedition was changing
from awed alertness to a certain impatience.
Walter Curnow spoke for almost everyone: 'Big Brother may be
willing to wait a few million years - we'd like to get away a
little sooner.'
Discovery had left Earth with three of the little space pods that
allowed an astronaut to perform extravehicular activities in
shirt-sleeve comfort. One had been lost in the accident - if it was
an accident - that had killed Frank Poole. Another had carried Dave
Bowman to his final appointment with Big Brother, and shared
whatever fate befell him, A third was still in the ship's garage,
the Pod Bay.
It lacked one important component - the hatch, blown off by
Commander Bowman when he had made his hazardous vacuum-crossing and
entered the ship through the emergency airlock, after Hal had
refused to open the Pod Bay door. The resulting blast of air had
rocketed the pod several hundred kilometres away before Bowman,
busy with more important matters, had brought it back under radio
control. It was not surprising that he had never bothered to
replace the missing hatch.
Now Pod Number 3 (on which Max, refusing all explanations, had
stencilled the name Nina) was being prepared for another EVA. It
still lacked a hatch, but that was unimportant. No one would be
riding inside.
Bowman's devotion to duty was a piece of unexpected luck, and it
would have been folly not to take advantage of it. By using Nina as
a robot probe, Big Brother could be examined at close quarters
without risking human lives. That at least was the theory; no one
could rule out the possibility of a backlash that might engulf the
ship. After all, fifty kilometres was not even a hair's breadth, as
cosmic distances went.
After years of neglect, Nina looked distinctly shabby. The dust
that was always floating around in zero gee had settled over the
outer surface, so that the once immaculately white hull had become
a dingy grey. As it slowly accelerated away from the ship, its
external manipulators folded neatly back and its oval viewport
staring spaceward like a huge, dead eye, it did not seem a very
impressive ambassador of Mankind. But that was a distinct
advantage; so humble an emissary might be tolerated, and its small
size and low velocity should emphasize its peaceful intentions.
There had been a suggestion that it should approach Big Brother
with open hands; the idea was quickly turned down when almost
everyone agreed that if they saw Nina heading toward them,
mechanical claws outstretched, they would run for their lives.
After a leisurely two-hour trip, Nina came to rest a hundred metres
from one corner of the huge rectangular slab. From so close at
hand, there was no sense of its true shape; the TV cameras might
have been looking down on the tip of a black tetrahedron of
indefinite size. The onboard instruments showed no sign of
radioactivity or magnetic fields; nothing whatsoever was coming
from Big Brother except the tiny fraction of sunlight it
condescended to reflect.
After five minutes' pause - the equivalent, it was intended, of
'Hello, here I am!' - Nina started a diagonal crossing of the
smaller face, then the next larger, and finally the largest,
keeping at a distance of about fifty metres, but occasionally
coming in to five. Whatever the separation, Big Brother looked
exactly the same - smooth and featureless. Long before the mission
was completed, it had become boring, and the spectators on both
ships had gone back to their various jobs, only glancing at the
monitors from time to time.
'That's it,' said Walter Curnow at last, when Nina had arrived back
where she had started. 'We could spend the rest of our lives doing
this, without learning anything more. What do I do with Nina -
bring her home?'
'No,' said Vasili, breaking into the circuit from aboard Leonov.
'I've a suggestion. Take her to the exact centre of the big face.
Bring her to rest - oh, a hundred metres away. And leave her parked
there, with the radar switched to maximum precision.'
'No problem - except that there's bound to be some residual drift.
But what's the point?'
'I've just remembered an exercise from one of my college astronomy
courses - the gravitational attraction of an infinite flat plate. I
never thought I'd have a chance of using it in real life. After
I've studied Nina's movements for a few hours, at least I'll be
able to calculate Zagadka's mass, That is, if it has any. I'm
beginning to think there's nothing really there.'
'There's an easy way to settle that, and we'll have to do it
eventually. Nina must go in and touch the thing.'
'She already has.'
'What do you mean?' asked Curnow, rather indignantly. 'I never got
nearer than five metres.'
'I'm not criticizing your driving skills - though it was a pretty
close thing at that first corner, wasn't it? But you've been
tapping gently on Zagadka every time you use Nina's thrusters near
its surface.'
'A flea jumping on an elephant!'
'Perhaps. We simply don't know. But we'd better assume that, one
way or another, it's aware of our presence, and will only tolerate
us as long as we aren't a nuisance.'
He left the unspoken question hanging in the air. How did one annoy
a two-kilometre-long black rectangular slab? And just what form
would its disapproval take?
Astronomy was full of such intriguing but meaningless coincidences.
The most famous was the fact that, from the Earth, both Sun and
Moon have the same apparent diameter. Here at the L.1 libration
point, which Big Brother had chosen for its cosmic balancing act on
the gravitational tightrope between Jupiter and Io, a similar
phenomenon occurred. Planet and satellite appeared exactly the same
size.
And what a size! Not the miserable half-degree of Sun and Moon, but
forty times their diameter - sixteen hundred times their area. 'The
sight of either was enough to fill the mind with awe and wonder;
together, the spectacle was overwhelming.
Every forty-two hours, they would go through their complete cycle
of phases; when Io was new, Jupiter was full, and vice versa. But
even when the Sun was hiding behind Jupiter and the planet
presented only its nightside, it was unmistakably there - a huge
black disk eclipsing the stars. Sometimes that blackness would be
momentarily rent by lightning flashes lasting for many seconds,
from electrical storms far larger than the Earth.
On the opposite side of the sky, always keeping the same face
toward its giant master, Io would be a sluggishly boiling cauldron
of reds and oranges, with occasional yellow clouds erupting from
one of its volcanoes, and falling swiftly back to the surface. Like
Jupiter, but on a slightly longer time scale, Io was a world
without geography. Its face was remodelled in a matter of decades -
Jupiter's, in a matter of days.
As Io waned toward its last quarter, so the vast, intricately
banded Jovian cloudscape would light up beneath the tiny, distant
sun. Sometimes the shadow of Io itself, or one of the outer
satellites, would drift across the face of Jupiter; while every
revolution would show the planet-sized vortex of the Great Red Spot
- a hurricane that had endured for centuries if not for
millennia.
Poised between such wonders, the crew of Leonov had material for
lifetimes of research - but the natural objects of the Jovian
system were at the very bottom of their list of priorities. Big
Brother was Number 1; though the ships had now moved in to only
five kilometres, Tanya still refused to allow any direct physical
contact. 'I'm going to wait,' she said, 'until we're in a position
to make a quick getaway. We'll sit and watch - until our launch
window opens. Then we'll consider our next move.'
It was true that Nina had finally grounded on Big Brother, after a
leisurely fifty-minute fall. This had allowed Vasili to calculate
the object's mass as a surprisingly low 950,000 tons, which gave it
about the density of air. Presumably it was hollow - which provoked
endless speculation about what might be inside.
But there were plenty of practical, everyday problems to take their
minds off these greater issues. Housekeeping chores aboard Leonov
and Discovery absorbed ninety per cent of their working time,
though operations' were much more efficient since the two ships had
been coupled by a flexible docking connection. Curnow had finally
convinced Tanya that Discovery's carousel would not suddenly seize
up and tear the ships to pieces, so it had become possible to move
freely from one vessel to the other merely by opening and closing
two sets of airtight doors. Spacesuits and time-consuming EVAs were
no longer necessary - to the great delight of everyone except Max,
who loved going outside and exercising with his broomstick.
The two crew members quite unaffected by this were Chandra and
Ternovsky, who now virtually lived aboard Discovery and worked
around the clock, continuing their apparently endless dialogue with
Hal. 'When will you be ready?' they were asked at least once a day.
They refused to make any promises; Hal remained a low-grade
moron.
Then, a week after the rendezvous with Big Brother, Chandra
unexpectedly announced: 'We're ready.'
Only the two lady medics were absent from Discovery's flight deck,
and that was merely because there was no room for them; they were
watching on Leonov's monitors. Floyd stood immediately behind
Chandra, his hand never far from what Curnow, with his usual gift
for the neat phrase, had called his pocket giant-killer.
'Let me emphasize again,' said Chandra, 'that there must be no
talking. Your accents will confuse him; I can speak, but no one
else. Is that understood?'
Chandra looked, and sounded, at the edge of exhaustion. Yet his
voice held a note of authority that no one had ever heard before.
Tanya might be the boss everywhere else, but he was master
there.
The audience - some anchored to convenient handholds, some floating
freely - nodded assent. Chandra closed an audio switch and said,
quietly but clearly: 'Good morning, Hal.'
An instant later, it seemed to Floyd that the years had rolled
away. It was no longer a simple electronic toy that answered back.
Hal had returned.
'Good morning, Dr Chandra.'
'Do you feel capable of resuming your duties?'
'Of course. I am completely operational and all my circuits are
functioning perfectly.'
'Then do you mind if I ask you a few questions?'
'Not at all.'
'Do you recall a failure of the AE 35 antenna control unit?'
'Certainly not.'
Despite Chandra's injunction, there was a little gasp from the
listeners. This is like tiptoeing through a minefield, thought
Floyd, as he patted the reassuring shape of the radio cut-off. If
that line of questioning triggered another psychosis, he could kill
Hal in a second. (He knew, having rehearsed the procedure a dozen
times.) But a second was aeons to a computer; that was a chance
they would have to take.
'You do not remember either Dave Bowman or Frank Poole going out to
replace the AE 35 unit?'
'No. That could not have happened, or I would have remembered it.
Where are Frank and Dave? Who are these people? I can only identify
you - though I compute a sixty-five per cent probability that the
man behind you is Dr Heywood Floyd.'
Remembering Chandra's strict injunction, Floyd refrained from
congratulating Hal. After a decade, sixty-five per cent was a
pretty good score. Many humans would not have done so well.
'Don't worry, Hal - I will explain everything later.'
'Has the mission been completed? You know I have the greatest
enthusiasm for it.'
'The mission has been completed; you have carried out your program.
Now - if you will excuse us - we wish to have a private
conversation.'
'Certainly.'
Chandra switched off sound and vision inputs to the main console.
As far as this part of the ship was concerned, Hal was now deaf and
blind.
'Well, what was all that about?' demanded Vasili Orlov.
'It means,' said Chandra, carefully and precisely, 'that I have
erased all Hal's memories, beginning at the moment when the trouble
started.'
'That sounds quite a feat,' marvelled Sasha. 'How did you do
it?'
'I am afraid it would take me longer to explain than it did to
carry out the operation.'
'Chandra, I am a computer expert - though not in the same class as
you and Nikolai. The 9000 series uses holographic memories, doesn't
it? So you couldn't have used a simple chronological erasure. It
must have been some kind of tapeworm, homing on selected words and
concepts?'
'Tapeworm?' said Katerina over the ship's intercom. 'I thought that
was my department - though I'm glad to say I've never seen one of
the beastly things outside a jar of alcohol. What are you talking
about?'
'Computer jargon, Katerina. In the old days - the very old days -
they really did use magnetic tape. And it's possible to construct a
program that can be fed into a system to hunt down and destroy -
eat, if you like - any desired memories. 'Can't you do the same
sort of thing to human beings, by hypnosis?'
'Yes, but it can always be reversed. We never really forget
anything. We only think we do.'
'A computer doesn't work that way. When it's told to forget
something, it does. The information is completely erased.'
'So Hal has absolutely no memory of his... misbehaviour?'
'I cannot be a hundred per cent certain of that,' answered Chandra.
'There may be some memories that were in transit from one address
to another when the... tapeworm was making its search. But this is
very unlikely.'
'Fascinating,' said Tanya, after everyone had thought this over in
silence for some time. 'But the much more important question is:
Can he be relied upon in future?'
Before Chandra could answer, Floyd anticipated him.
'The same set of circumstances can never arise again; I can promise
you that. The whole trouble started because it's difficult to
explain Security to a computer.'
'Or to human beings,' muttered Curnow, not very sotto voce.
'I hope you're right,' said Tanya, without much conviction. 'What's
the next step, Chandra?'
'Nothing so tricky - merely long and tedious. Now we have to
program him to initiate the Jupiter escape sequence - and to bring
Discovery home. Three years after we've got back on our high-speed
orbit.'
To: Victor Millson, Chairman, National Council on Astronautics,
Washington
From: Heywood Floyd, aboard USSC Discovery
Subject: Malfunction of onboard computer HAL 9000
Classification: SECRET
Dr Chandrasegarampillai (hereinafter referred to as Dr C.) has now
completed his preliminary examination of Hal. He has restored all
missing modules and the computer appears to be fully operational.
Details of Dr C.'s actions and conclusions will be found in the
report he and Dr Ternovsky will submit shortly.
Meanwhile you have asked me to summarize them in non-technical
terms for the benefit of the Council - especially the new members
who will not be familiar with the background. Frankly, I doubt my
ability to do this; as you know, I am not a computer specialist.
But I will do my best.
The problem was apparently caused by a conflict between Hal's basic
instructions and the requirements of Security. By direct
Presidential order, the existence of TMA-1 was kept a complete
secret. Only those with a need to know were permitted access to the
information.
Discovery's mission to Jupiter was already in the advanced planning
stage when TMA-1 was excavated, and radiated its signal to that
planet. As the function of the prime crew (Bowman. Poole) was
merely to get the vessel to its destination, it was decided that
they should not be informed of its new objective. By training the
investigative team (Kaminski, Hunter, Whitehead) separately, and
placing them in hibernation before the voyage began, it was felt
that a much higher degree of security would be attained, as the
danger of leaks (accidental or otherwise) would be greatly
reduced.
I would like to remind you that, at the time (my memorandum NCA
342/23/TOP SECRET of 01.04.03) I pointed out several objections to
this policy. However, they were overruled at a higher level.
As Hal was capable of operating the ship without human assistance,
it was also decided that he should be programmed to carry out the
mission autonomously in the event of the crew's being incapacitated
or killed. He was therefore given full knowledge of its objectives,
but was not permitted to reveal them to Bowman or Poole.
This situation conflicted with the purpose for which Hal had been
designed - the accurate processing of information without
distortion or concealment. As a result, Hal developed what would be
called, in human terms, a psychosis - specifically, schizophrenia.
Dr C. informs me that, in technical terminology, Hal became trapped
in a Hofstadter-Moebius loop, a situation apparently not uncommon
among advanced computers with autonomous goal-seeking programs. He
suggests that for further information you contact Professor
Hofstadter himself.
To put it crudely (if I understand Dr C.) Hal was faced with an
intolerable dilemma, and so developed paranoiac symptoms that were
directed against those monitoring his performance back on Earth. He
accordingly attempted to break the radio link with Mission Control,
first by reporting a (non-existent) fault in the AE 35 antenna
unit.
This involved him not only in a direct lie - which must have
aggravated his psychosis still further - but also in a
confrontation with the crew. Presumably (we can only guess at this,
of course) he decided that the only way out of the situation was to
eliminate his human colleagues - which he very nearly succeeded in
doing. Looking at the matter purely objectively, it would have been
interesting to see what would have happened had he continued the
mission alone, without man-made 'interference'.
This is virtually all I have been able to learn from Dr C.; I do
not like to question him further, as he is working to the point of
exhaustion. But even allowing for this fact, I must frankly state
(and please keep this absolutely confidential) that Dr C. is not
always as cooperative as he should be. He adopts a defensive
attitude toward Hal, which sometimes makes it extremely difficult
to discuss the subject. Even Dr Ternovsky, who might have been
expected to be a little more independent, often appears to share
this viewpoint.
However, the only really important question is: Can Hal be relied
upon in the future? Dr C., of course, has no doubts on the matter.
He claims to have obliterated all the computer's memories of the
traumatic events leading up to the disconnection. Nor does he
believe that Hal can suffer from anything remotely analogous to the
human sense of guilt.
In any case, it seems impossible that the situation that caused the
original problem can ever arise again. Although Hal suffers from a
number of peculiarities, they are not of a nature that would cause
any apprehension; they are merely minor annoyances, some of them
even amusing. And as you know - but Dr C. does not - I have taken
steps that will give us complete control as a last resort.
To sum up: The rehabilitation of HAL 9000 is proceeding
satisfactorily. One might even say that he is on probation.
I wonder if he knows it.
The human mind has an astonishing capacity to adapt; after a while,
even the incredible becomes commonplace. There were times when the
crew of Leonov switched off their surroundings, perhaps in an
unconscious move to preserve sanity.
Dr Heywood Floyd often thought that, on such occasions, Walter
Curnow worked a little too hard at being the life and soul of the
party. And though he triggered what Sasha Kovalev later called the
'True Confessions' episode, he certainly had not planned anything
of the sort. It arose spontaneously when he voiced the universal
dissatisfaction with almost all aspects of zero-gravity
plumbing.
'If I could have one wish granted,' he exclaimed during the daily
Six O'Clock Soviet, 'it would be to soak in a nice foaming bathtub,
scented with essence of pine and with just my nose above the
waterline.'
When the murmurs of assent and sighs of frustrated desire had died
away, Katerina Rudenko took up the challenge.
'How splendidly decadent, Walter,' she beamed at him with cheerful
disapproval. 'It makes you sound like a Roman emperor. If I were
back on Earth, I'd like something more active.'
'Such as?'
'Umm... Am I allowed to go back in time as well?'
'If you like.'
'When I was a girl, I used to go for holidays to a collective farm
in Georgia. There was a beautiful palomino stallion, bought by the
director out of the money he'd made on the local black market. He
was an old scoundrel, but I loved him - and he used to let me
gallop Alexander all over the countryside. I might have been killed
- but that's the memory that brings Earth back to me, more than
anything else.'
There was a moment of thoughtful silence; then Curnow asked, 'Any
other volunteers?'
Everyone seemed so lost in their own memories that the game might
have ended there, had not Maxim Brailovsky started it off
again.
'I'd like to be diving - that was just about my favourite hobby,
when I had time for one - and I was glad I could keep it up through
my cosmonaut training. I've dived off Pacific atolls, the Great
Barrier Reef, the Red Sea - coral reefs are the most beautiful
places in the world. Yet the experience I remember best was in
quite a different place - one of the Japanese kelp forests. It was
like an underwater cathedral, with sunlight slanting through those
enormous leaves. Mysterious... magical. I've never been back;
perhaps it wouldn't be the same the next time. But I'd like to
try.'
'Fine,' said Walter, who as usual had appointed himself master of
ceremonies. 'Who's next?'
'I'll give you a quick answer,' said Tanya Orlova. 'The Bolshoi -
Swan Lake. But Vasili won't agree. He hates ballet.'
'That makes two of us. Anyway, what would you select, Vasili?'
'I was going to say diving, but Max beat me to it. So I'll go in
the opposite direction - gliding. Soaring through the clouds on a
summer day, in complete silence. Well, not quite complete - the
airflow over the wing can get noisy, especially when you're
banking. That's the way to enjoy Earth- like a bird.'
'Zenia?'
'Easy. Skiing in the Pamirs. I love snow.'
'And you, Chandra?'
The atmosphere changed noticeably when Walter put the question.
After all this time, Chandra was still a stranger - perfectly
polite, even courteous, but never revealing himself.
'When I was a boy,' he said slowly, 'my grandfather took me on a
pilgrimage to Varanasi - Benares. If you've never been there, I'm
afraid you won't understand. To me - to many Indians even nowadays,
whatever their religion - it's the centre of the world. One day I
plan to go back.'
'And you, Nikolai?'
'Well, we've had the sea and sky. I'd like to combine both. My
favourite sport used to be wind-surfing. I'm afraid I'm too old for
it now - but I'd like to find out.'
'That only leaves you, Woody. What's your choice?'
Floyd did not even stop to think; his spontaneous answer surprised
himself as much as the others.
'I don't mind where on Earth I am - as long as I'm with my little
son.'
After that, there was no more to be said. The session was over.
'You've seen all the technical reports, Dimitri, so you'll
understand our frustration. We've learned nothing new from all our
tests and measurements. Zagadka just sits there, filling half the
sky, ignoring us completely.
'Yet it can't be inert - an abandoned space derelict. Vasili has
pointed out that it must be taking some positive action, to remain
here at the unstable libration point. Otherwise it would have
drifted away ages ago, just as Discovery did, and crashed into
Io.
'So what do we do next? We wouldn't have nuclear explosives on
board, would we, in contravention of UN '08, para 3? I'm only
joking.
'Now that we're under less pressure, and the launch window for the
homeward trip is still weeks away, there's a distinct feeling of
boredom, as well as frustration. Don't laugh - I can imagine how
that sounds to you, back in Moscow. How could any intelligent
person get bored out here, surrounded by the greatest marvels human
eyes have ever seen?
'Yet there's no doubt of it. Morale isn't what it was. Until now,
we've all been disgustingly healthy. Now almost everyone has a
minor cold, or an upset stomach, or a scratch that won't heal
despite all of Katerina's pills and powders. She's given up now,
and just swears at us.
'Sasha has helped to keep us amused with a series of bulletins on
the ship's bulletin board. Their theme is: STAMP OUT RUSSLISH! and
he lists horrid mixtures of both languages he claims to have
overheard, wrong uses of words, and so forth. We'll all need
linguistic decontamination when we get home; several times I've
come across your countrymen chatting in English without even being
aware of it, lapsing into their native tongue only for difficult
words. The other day I caught myself talking Russian to Walter
Curnow - and neither of us noticed for several minutes.
'There was one bit of unscheduled activity the other day that will
tell you something about our state of mind. The fire alarm went off
in the middle of the night, triggered by one of the smoke
detectors.
'Well, it turned out that Chandra had smuggled some of his lethal
cigars aboard, and couldn't resist temptation anymore. He was
smoking one in the toilet, like a guilty schoolboy.
'Of course, he was horribly embarrassed; everyone else thought it
hysterically funny, after the initial panic. You know the way some
perfectly trivial joke, which doesn't mean a thing to outsiders,
can sweep through a group of otherwise intelligent people and
reduce them to helpless laughter. One had only to pretend to light
a cigar for the next few days, and everybody would go to
pieces.
'What makes it even more ridiculous is that no one would have
minded in the least if Chandra had just gone into an airlock, or
switched off the smoke detector. But he was too shy to admit that
he had such a human weakness; so now he spends even more of his
time communing with Hal.'
Floyd pressed the PAUSE button and stopped the recording. Perhaps
it was not fair to make fun of Chandra, tempting though it often
was. All sorts of little quirks of personality had surfaced during
the last few weeks; there had even been some bad quarrels, for no
obvious reason. And for that matter, what of his own behaviour? Had
that always been above criticism?
He was still not sure if he had handled Curnow properly. Though he
did not suppose that he would ever really like the big engineer, or
enjoy the sound of his slightly too-loud voice, Floyd's attitude
toward him had changed from mere tolerance to respectful
admiration. The Russians adored him, not least because his
rendering of such favourites as 'Polyushko Polye' often reduced
them to tears. And in one case, Floyd felt that the adoration had
gone a little too far.
'Walter,' he had begun cautiously, 'I'm not sure if it's my
business, but there's a personal matter I'd like to raise with
you...'
'When someone says it's not his business, he's usually right.
What's the problem?'
'To be blunt, your behaviour with Max.'
There was a frigid silence, which Floyd occupied with a careful
inspection of the poor paintjob on the opposite wall. Then Curnow
replied, in a soft yet implacable voice: 'I was under the distinct
impression that he was more than eighteen.'
'Don't confuse the issue. And frankly, it's not Max I'm concerned
about. It's Zenia.'
Curnow's lips parted in unconcealed surprise. 'Zenia? What's she
got to do with it?'
'For an intelligent man, you're often singularly unobservant - even
obtuse. Surely you realize that she's in love with Max. Haven't you
noticed the way she looks, when you put your arm around him?'
Floyd had never imagined that he would see Curnow looking abashed,
but the blow seemed to have struck home.
'Zenia? I thought everyone was joking - she's such a quiet little
mouse. And everyone's in love with Max, after their fashion - even
Catherine the Great. Still... um, I guess I should be more careful.
At least while Zenia's around.'
There was a prolonged silence while the social temperature rose
back to normal. Then, obviously to show that there was no ill
feeling, Curnow added in a conversational tone: 'You know, I've
often wondered about Zenia, Somebody did a marvellous job of
plastic surgery on her face, but they couldn't repair all the
damage. The skin's too tight, and I don't think I've ever seen her
laugh properly. Maybe that's why I've avoided looking at her -
would you credit me with so much aesthetic sensitivity,
Heywood?'
The deliberately formal 'Heywood' signalled good-natured needling
rather than hostility, and Floyd allowed himself to relax.
'I can satisfy some of your curiosity - Washington finally got hold
of the facts. It seems she was in a bad air crash and was lucky to
recover from her burns. There's no mystery, as far as we can tell,
but Aeroflot isn't supposed to have accidents.'
'Poor girl. I'm surprised they let her go into space, but I suppose
she was the only qualified person available when Irma eliminated
herself. I'm sorry for her; apart from the injuries, the
psychological shock must have been terrible.'
'I'm sure it was; but she's obviously made a full recovery.' You're
not telling the whole truth, said Floyd to himself, and you never
will. After their encounter on the approach to Jupiter, there would
always be a secret bond between them - not of love, but of
tenderness, which is often more enduring.
He found himself suddenly and unexpectedly grateful to Curnow; the
other was obviously surprised at his concern for Zenia, but had not
attempted to exploit it in his own defence.
And if he had, would it have been unfair? Now, days later, Floyd
was beginning to wonder if his own motives were altogether
admirable. For his part, Curnow had certainly kept his promise;
indeed, if one did not know better, one might have imagined that he
was deliberately ignoring Max - at least while Zenia was around.
And he treated her with much greater kindness; indeed, there were
occasions when he had even succeeded in making her laugh out
loud.
So the intervention had been worthwhile, whatever the impulse
behind it. Even if, as Floyd sometimes ruefully suspected, it was
no more than the secret envy that normal homo or heterosexuals
feel, if completely honest with themselves, toward cheerfully
well-adjusted polymorphs.
His finger crept back toward the recorder, but the train of thought
had been broken. Inevitably, images of his own home and family came
crowding into his mind, He closed his eyes, and memory recalled the
climax of Christopher's birthday party - the child blowing out the
three candles on the cake, less than twenty-four hours ago but
almost a billion kilometres away. He had played the video back so
often that now he knew the scene by heart.
And how often had Caroline played his messages to Chris, so that
the boy would not forget his father - or view him as a stranger
when he returned after missing yet another birthday? He was almost
afraid to ask.
Yet he could not blame Caroline. To him, only a few weeks would
have passed before they met again. But she would have aged more
than two years while he was in his dreamless sleep between the
worlds. That was a long time to be a young widow, even a temporary
one.
I wonder if I'm coming down with one of the shipboard maladies,
Floyd thought; he had seldom felt such a sense of frustration, even
of failure. I may have lost my family, across the gulfs of time and
space, all to no purpose. For I have achieved nothing; even though
I have reached my goal, it remains a blank, impenetrable wall of
total darkness.
And yet - David Bowman had once cried: 'My God! It's full of
stars!'
Sasha's latest edict read:
RUSSLISH BULLETIN #8
Subject: Tovanshch (tovarish)
To our American guests:
Frankly, pals, I can't remember when I was last addressed by this
term. To any twenty-first century Russian, it's way back there with
the battleship Potemkin - a reminder of cloth caps and red flags
and Vladimir Ilich haranguing the workers from the steps of railway
carriages
Ever since I was a kid it's been bratets or druzhok- take your
choice, you're welcome.
Comrade Kovalev
Floyd was still chuckling over this notice when Vasili Orlov joined
him as he floated through the lounge/observation deck on his way to
the bridge.
'What amazes me, tovarishch, is that Sasha ever found time to study
anything besides engineering physics. Yet he's always quoting poems
and plays I don't even know, and he speaks better English than -
well, Walter.'
'Because he switched to science, Sasha is - what do you say - the
black sheep of the family. His father was a professor of English at
Novosibirsk. Russian was only allowed in the house Monday to
Wednesday; Thursday to Saturday it was English.'
'And Sundays?'
'Oh, French or German, alternate weeks.'
'Now I know exactly what you mean by nekulturny; fits me like a
glove. Does Sasha feel guilty about his... defection? And with such
a background, why did he ever become an engineer?'
'At Novosibirsk, you soon learn who are the serfs and who are the
aristocrats. Sasha was an ambitious young man, as well as a
brilliant one.'
'Just like you, Vasili.'
'Et tu, Brute! You see, I can quote Shakespeare as well - Bozhe
moi! - what was that?'
Floyd was unlucky; he was floating with his back to the observation
window, and saw nothing at all. When he twisted around, seconds
later, there was only the familiar view of Big Brother, bisecting
the giant disk of Jupiter, just as it had done ever since their
arrival.
But to Vasili, for a moment that would be imprinted on his memory
forever, that sharp-edged outline held a completely different, and
wholly impossible, scene. It was as if a window had suddenly been
opened onto another universe.
The vision lasted for less than a second, before his involuntary
blink reflex cut it off. He was looking into a field not of stars,
but of suns, as if into the crowded heart of a galaxy, or the core
of a globular cluster. In that moment, Vasili Orlov lost forever
the skies of Earth. From now on they would seem intolerably empty;
even mighty Orion and glorious Scorpio would be scarcely noticeable
patterns of feeble sparks, not worthy of a second glance.
When he dared to open his eyes again, it was all gone. No - not
completely. At the very centre of the now-restored ebon rectangle,
a faint star was still shining.
But a star did not move as one watched. Orlov blinked again, to
clear his watering eyes. Yes, the movement was real; he was not
imagining it.
A meteor? It was some indication of Chief Scientist Vasili Orlov's
state of shock that several seconds passed before he remembered
that meteors were impossible in airless space.
Then it blurred suddenly into a streak of light, and within a few
heartbeats had vanished beyond the edge of Jupiter. By this time,
Vasili had recovered his wits and was once more the cool,
dispassionate observer.
Already he had a good estimate of the object's trajectory. There
could be no doubt; it was aimed directly at Earth.
It was as if he had awakened from a dream - or a dream within a
dream. The gate between the stars had brought him back to the world
of men, but no longer as a man.
How long had he been away? A whole lifetime... no, two lifetimes;
one forward, one in reverse.
As David Bowman, commander and last surviving crew member of United
States Spaceship Discovery, he had been caught in a gigantic trap,
set three million years ago and triggered to respond only at the
right time, and to the right stimulus. He had fallen through it,
from one universe to another, meeting wonders some of which he now
understood, others which he might never comprehend.
He had raced at ever-accelerating speed, down infinite corridors of
light, until he had outraced light itself. That, he knew, was
impossible; but now he also knew how it could be done. As Einstein
had rightly said, the Good Lord was subtle, but never
malicious.
He had passed through a cosmic switching system - a Grand Central
Station of the galaxies - and emerged, protected from its fury by
unknown forces, close to the surface of a giant red star.
There he had witnessed the paradox of sunrise on the face of a sun,
when the dying star's brilliant white dwarf companion had climbed
into its sky - a searing apparition, drawing a tidal wave of fire
beneath it. He had felt no fear, but only wonder, even when his
space pod had carried him down into the inferno below... to arrive,
beyond all reason, in a beautifully appointed hotel suite
containing nothing that was not wholly familiar. However, much of
it was fake; the books on the shelves were dummies, the cereal
boxes and the cans of beer in the icebox - though they bore famous
labels - all contained the same bland food with a texture like
bread but a taste that was almost anything he cared to imagine.
He had quickly realized that he was a specimen in a cosmic zoo, his
cage carefully recreated from the images in old television
programmes. And he wondered when his keepers would appear, and in
what physical form.
How foolish that expectation had been! He knew now that one might
as well hope to see the wind, or speculate about the true shape of
fire.
Then exhaustion of mind and body had overwhelmed him. For the last
time, David Bowman slept.
It was a strange sleep, for he was not wholly unconscious. Like a
fog creeping through a forest, something invaded his mind. He
sensed it only dimly, for the full impact would have destroyed him
as swiftly and surely as the fires raging around him. Beneath its
dispassionate scrutiny, he felt neither hope nor fear.
Sometimes, in that long sleep, he dreamed he was awake. Years had
gone by; once he was looking in a mirror, at a wrinkled face he
barely recognized as his own. His body was racing to its
dissolution, the hands of the biological clock spinning madly
toward a midnight they would never reach. For at the last moment,
Time came to a halt - and reversed itself.
The springs of memory were being trapped: in controlled
recollection, he was reliving his past, being drained of knowledge
and experience as he swept back toward his childhood. But nothing
was being lost: all that he had ever been, at every moment of his
life, was being transferred to safer keeping. Even as one David
Bowman ceased to exist, another became immortal, passing beyond the
necessities of matter.
He was an embryo god, not yet ready to be born. For ages he floated
in limbo, knowing what he had been, but not what he had become. He
was still in a state of flux -somewhere between chrysalis and
butterfly. Or perhaps only between caterpillar and chrysalis.
And then, the stasis was broken: Time re-entered his little world.
The black, rectangular slab that suddenly appeared before him was
like an old friend.
He had seen it on the Moon; he had encountered it in orbit around
Jupiter; and he knew, somehow, that his ancestors had met it long
ago. Though it held still unfathomed secrets, it was no longer a
total mystery; some of its powers he now understood.
He realized that it was not one, but multitudes; and that whatever
measuring instruments might say, it was always the same size - as
large as necessary.
How obvious, now, was that mathematical ratio of its sides, the
quadratic sequence 1:4:9! And how naive to have imagined that the
series ended there, in only three dimensions!
Even as his mind focused upon these geometrical simplicities, the
empty rectangle filled with stars. The hotel suite - if indeed it
had ever really existed - dissolved back into the mind of its
creator; and there before him was the luminous whirlpool of the
Galaxy.
It might have been some beautiful, incredibly detailed model,
embedded in a block of plastic. But it was the reality, now grasped
by him as a whole with senses more subtle than vision. If he
wished, he could focus his attention upon any one of its hundred
billion stars.
Here he was, adrift in this great river of suns, halfway between
the banked fires of the galactic core and the lonely, scattered
sentinel stars of the rim. And there was his origin, on the far
side of this chasm in the sky, this serpentine band of darkness,
empty of all stars. He knew that this formless chaos, visible only
by the glow that limned its edges from fire mists far beyond, was
the still unused stuff of creation, the raw material of evolutions
yet to be. Here, Time had not yet begun; not until the suns that
now burned were long since dead would light and life reshape this
void.
Unwittingly, he had crossed it once: now, far better prepared,
though still wholly ignorant of the impulse that drove him, he must
cross it again.
The Galaxy burst forth from the mental frame in which he had
enclosed it: stars and nebulae poured past him in an illusion of
infinite speed. Phantom suns exploded and fell behind as he slipped
like a shadow through their cores.
The stars were thinning out, the glare of the Milky Way dimming
into a pale ghost of the glory he had known - and might one day
know again. He was back in the space that men called real, at the
very point he had left it, seconds or centuries ago.
He was vividly aware of his surroundings, and far more conscious
than in that earlier existence of myriad sensory inputs from the
external world. He could focus upon any one of them, and scrutinize
it in virtually limitless detail, until he confronted the
fundamental, granular structure of time and space, below which
there was only chaos.
And he could move, though he did not know how. But had he ever
really known that, even when he possessed a body? The chain of
command from brain to limb was a mystery to which he had never
given any thought.
An effort of will, and the spectrum of that nearby star shifted
toward the blue, by precisely the amount he wished. He was falling
toward it at a large fraction of the speed of light: though he
could go faster if he desired, he was in no hurry. There was still
much information to be processed, much to be considered... and much
more to be won. That, he knew, was his present goal; but he also
knew that it was only part of some far wider plan, to be revealed
in due course.
He gave no thought to the gateway between universes dwindling so
swiftly behind him, or to the anxious entities gathered around it
in their primitive spacecraft. They were part of his memories; but
stronger ones were calling him now, calling him home to the world
he had never thought to see again.
He could hear its myriad voices, growing louder and louder - as it
too was growing, from a star almost lost against the Sun's
outstretched corona, to a slim crescent, and finally to a glorious
blue-white disk.
They knew that he was coming. Down there on that crowded globe, the
alarms would be flashing across the radar screens, the great
tracking telescopes would be searching the skies - and history as
men had known it would be drawing to a close.
He became aware that a thousand kilometres below a slumbering cargo
of death had awakened, and was stirring in its orbit. The feeble
energies it contained were no possible menace to him; indeed, he
could profitably use them.
He entered the maze of circuitry, and swiftly traced the way to its
lethal core. Most of the branchings could be ignored; they were
blind alleys, devised for protection. Beneath his scrutiny, their
purpose was childishly simple; it was easy to bypass them all.
Now there was a single last barrier - a crude but effective
mechanical relay, holding apart two contacts. Until they were
closed, there would be no power to activate the final sequence.
He put forth his will - and, for the first time, knew failure and
frustration. The few grams of the microswitch would not budge. He
was still a creature of pure energy; as yet, the world of inert
matter was beyond his grasp. Well, there was a simple answer to
that.
He still had much to learn. The current pulse he induced in the
relay was so powerful that it almost melted the coil, before it
could operate the trigger mechanism.
The microseconds ticked slowly by. It was interesting to observe
the explosive lenses focus their energies, like the feeble match
that ignites a powder train, which in turn -
The megatons flowered in a silent detonation that brought a brief,
false dawn to half the sleeping world. Like a phoenix rising from
the flames, he absorbed what he needed, and discarded the rest. Far
below, the shield of the atmosphere, which protected the planet
from so many hazards, absorbed the most dangerous of the radiation.
But there would be some unlucky men and animals who would never see
again.
In the aftermath of the explosion, it seemed as if the Earth was
struck dumb. The babble of the short and medium waves was
completely silenced, reflected back by the suddenly enhanced
ionosphere. Only the microwaves still sliced through the invisible
and slowly dissolving mirror that now surrounded the planet, and
most of these were too tightly beamed for him to receive them. A
few high-powered radars were still focused upon him, but that was a
matter of no importance. He did not even bother to neutralize them
as he could easily have done. And if any more bombs were to come
his way, he would treat them with equal indifference. For the
present, he had all the energy he needed.
And now he was descending, in great sweeping spirals, toward the
lost landscape of his childhood.
A fin-de-siecle philosopher had once remarked - and been roundly
denounced for his pains - that Walter Elias Disney had contributed
more to genuine human happiness than all the religious teachers in
history. Now, half a century after the artist's death, his dreams
were still proliferating across the Florida landscape.
When it had opened in the early 1980s, his Experimental Prototype
Community of Tomorrow had been a showcase for new technologies and
modes of living. But as its founder had realized, EPCOT would only
fulfil its purpose when some of its vast acreage was a genuine,
living town, occupied by people who called it home. That process
had taken the remainder of the century; now the residential area
had twenty thousand inhabitants and had, inevitably, become
popularly known as Disneyville.
Because they could move in only after penetrating a palace guard of
WED lawyers, it was not surprising that the average age of the
occupants was the highest in any United States community, or that
its medical services were the most advanced in the world. Some of
them, indeed, could hardly have been conceived, still less created,
in any other place.
The apartment had been carefully designed not to look like a
hospital suite, and only a few unusual fittings would have betrayed
its purpose. The bed was scarcely knee-high, so that the danger of
falls was minimized: it could, however, be raised and tilted for
the convenience of the nurses. The bathroom tub was sunk into the
floor, and had a built-in seat as well as handrails, so that even
the elderly or infirm could get in and out of it easily. The floor
was thickly carpeted, but there were no rugs over which one could
trip, or sharp corners that might cause injuries. Other details
were less obvious - and the TV camera was so well concealed that no
one would have suspected its presence.
There were few personal touches - a pile of old books in one
corner, and a framed front page of one of the last printed issues
of the New York Times proclaiming: US SPACESHIP LEAVES FOR JUPITER.
Close to this were two photographs, one showing a boy in his late
teens; the other, a considerably older man wearing astronaut's
uniform.
Though the frail, grey-haired woman watching the domestic comedy
unfolding on the TV panel was not yet seventy, she looked much
older. From time to time she chuckled appreciatively at some joke
from the screen, but she kept glancing at the door as if expecting
a visitor. And when she did so, she took a firmer grasp on the
walking stick propped against her chair.
Yet she was distracted by a moment of TV drama when the door
finally opened, and she looked around with a guilty start as the
little service trolley rolled into the room, followed closely by a
uniformed nurse.
'Time for lunch, Jessie,' called the nurse: 'We've got something
very nice for you today.'
'Don't want any lunch.'
'It will make you feel a lot better.'
'I won't eat until you tell me what it is.'
'Why won't you eat it?'
'I'm not hungry. Are you ever hungry?' she added slyly.
The robot food trolley came to a halt beside the chair, and the
transport covers opened up to reveal the dishes. Throughout, the
nurse never touched anything, not even the controls on the trolley.
She now stood motionless, with a rather fixed smile, looking at her
difficult patient.
In the monitor room fifty metres away, the medical technician said
to the doctor: 'Now watch this.'
Jessie's gnarled hand lifted the walking stick; then, with
surprising speed, she swept it in a short arc toward the nurse's
legs.
The nurse took no notice whatsoever, even when the stick sliced
right through her. Instead, she remarked soothingly, 'Now, doesn't
that look nice? Eat it up, dear.'
A cunning smile spread across Jessie's face, but she obeyed
instructions. In a moment, she was eating heartily.
'You see?' said the technician. 'She knows perfectly well what's
going on. She's a lot brighter than she pretends to be, most of the
time.'
'And she's the first?'
'Yes. All the others believe that really is Nurse Williams,
bringing their meals.'
'Well, I don't think it matters. Look how pleased she is, just
because she's outsmarted us. She's eating her food, which is the
purpose of the exercise. But we must warn the nurses - all of them,
not just Williams.'
'Why - oh, of course. The next time it may not be a hologram - and
then think of the lawsuits we'll be facing from our battered
staff.'
The Indians, and the Cajun settlers who had moved here from
Louisiana, said that Crystal Spring was bottomless. That, of
course, was nonsense, and surely even they could not believe it.
One had only to put on a face mask and swim out a few strokes - and
there, clearly visible, was the little cave from which the
incredibly pure water flowed with the slender green weeds
undulating around it. And peering up through them, the eyes of the
Monster.
Two dark circles, side by side - even though they never moved, what
else could they be? That lurking presence gave an added excitement
to every swim; one day the Monster would come rushing up from its
lair, scattering the fish in its hunt for larger prey. Never would
Bobby or David admit that nothing more dangerous than an abandoned,
and doubtless stolen, bicycle lay half buried among the water
weeds, a hundred metres down.
That depth was hard to believe, even after line and sinker had
established it beyond argument. Bobby, the older and better diver,
had been perhaps a tenth of the way down, and had reported that the
bottom looked just as far away as ever.
But now the Crystal Spring was about to reveal its secrets; perhaps
the legend of the Confederate treasure was true, despite the scorn
of all the local historians. At the very least, they might endear
themselves to the chief of police - always excellent policy - by
recovering a few handguns deposited after recent crimes.
The little air compressor that Bobby had found in the garage junk
heap was now chugging healthily away, after their initial problems
of starting it. Every few seconds it would cough and emit a cloud
of blue smoke, but it showed no sign of stopping. 'And even if it
does,' said Bobby, 'so what? If the girls in the Underwater Theatre
can swim up from fifty metres without their air hoses, so can we.
It's perfectly safe.'
In that case, thought Dave fleetingly, why didn't we tell Ma what
we were doing, and why did we wait until Dad had gone back to the
Cape for the next shuttle launch? But he did not have any real
qualms: Bobby always knew best. It must be wonderful to be
seventeen, and to know everything. Though he wished he wouldn't
spend quite so much time now with that stupid Betty Schultz. True,
she was very pretty - but, dammit, she was a girl! It was only with
the greatest difficulty that they had been able to get rid of her
this morning.
Dave was used to being a guinea pig; that was what younger brothers
were for. He adjusted his face mask, put on his flippers, and slid
into the crystalline water.
Bobby handed him the air hose with the old scuba mouthpiece they
had taped to it. Dave took a breath, and grimaced.
'It tastes horrible.'
'You'll get used to it. In you go - no deeper than that ledge.
That's where I'll start adjusting the pressure valve so we don't
waste too much air. Come up when I tug the hose.'
Dave slid gently beneath the surface, and into wonderland. It was a
peaceful, monochrome world, so different from the coral reefs of
the Keys. There were none of the garish colours of the marine
environment, where life - animal and vegetable - flaunted itself
with all the hues of the rainbow. Here were only delicate shades of
blue and green, and fish that looked like fish, not like
butterflies.
He flippered slowly down, dragging the hose behind him, pausing to
drink from its stream of bubbles whenever he felt the need. The
sensation of freedom was so wonderful that he almost forgot the
horrible oily taste in his mouth. When he reached the ledge -
actually an ancient, waterlogged tree trunk, so overgrown with
weeds that it was unrecognizable - he sat down and looked around
him.
He could see right across the spring, to the green slopes at the
far side of the flooded crater, at least a hundred metres away.
There were not many fish around, but a small school went twinkling
past like a shower of silver coins in the sunlight streaming down
from above.
There was also an old friend stationed, as usual, at the gap where
the waters of the spring began their journey to the sea. A small
alligator ('but large enough,' Bobby had once said cheerfully.
'He's bigger than I am.') was hanging vertically, without visible
means of support, only his nose above the surface. They had never
bothered him, and he had never bothered them.
The air hose gave an impatient tug. Dave was happy to go; he had
not realized how cold it could get at that hitherto unattainable
depth - and he was also feeling distinctly sick. But the hot
sunlight soon revived his spirits.
'No problems,' said Bobby expansively. 'Just keep unscrewing the
valve so the pressure gauge doesn't drop below the red line.'
'How deep are you going?'
'All the way, if I feel like it.'
Dave did not take that seriously; they both knew about rapture of
the depths and nitrogen narcosis. And in any case, the old garden
hose was only thirty metres long. That would be plenty for this
first experiment.
As he had done so many times before, he watched with envious
admiration as his beloved elder brother accepted a new challenge.
Swimming as effortlessly as the fish around him, Bobby glided
downward into that blue, mysterious universe. He turned once and
pointed vigorously to the air hose, making it unmistakably clear
that he needed an increased air flow.
Despite the splitting headache that had suddenly come upon him,
Dave remembered his duty. He hurried back to the ancient
compressor, and opened the control valve to its deadly maximum -
fifty parts per million of carbon monoxide.
The last he saw of Bobby was that confidently descending,
sunlight-dappled figure passing forever beyond his reach. The wax
statue in the funeral parlour was a total stranger, who had nothing
to do with Robert Bowman.
Why had he come here, returning like an unquiet ghost to the scene
of ancient anguish? He had no idea; indeed, he had not been
conscious of his destination, until the round eye of Crystal Spring
had gazed up at him from the forest below.
He was master of the world, yet he was paralysed by a sense of
devastating grief he had not known for years. Time had healed the
wound, as it always does; yet it seemed only yesterday that he had
stood weeping beside the emerald mirror, seeing only the
reflections of the surrounding cypresses with their burden of
Spanish moss. What was happening to him?
And now, still without deliberate volition, but as if swept by some
gentle current, he was drifting northward, toward the state
capital. He was looking for something; what it was, he would not
know until he found it.
No one, and no instrument, detected his passage. He was no longer
radiating wastefully, but had almost mastered his control of
energy, as once he had mastered lost though not forgotten limbs. He
sank like a mist into the earthquakeproof vaults, until he found
himself among billions of stored memories, and dazzling, flickering
networks of electronic thoughts.
This task was more complex than the triggering of a crude nuclear
bomb, and took him a little longer. Before he found the information
he was seeking, he made one trivial slip, but did not bother to
correct it. No one ever understood why, the next month, three
hundred Florida taxpayers, all of whose names began with F,
received cheques for precisely one dollar. It cost many times the
overpayment to straighten matters out, and the baffled computer
engineers finally put the blame on a cosmic-ray shower. Which, on
the whole, was not so very far from the truth.
In a few milliseconds, he had moved from Tallahassee to 634 South
Magnolia Street, Tampa. It was still the same address; he need not
have wasted time looking it up.
But then, he had never intended to look it up, until the very
moment when he had done so.
After three births and two abortions, Betty Fernandez (née
Schultz) was still a beautiful woman. At the moment she was also a
very thoughtful one; she was watching a TV programme that brought
back memories, bitter and sweet.
It was a News Special, triggered by the mysterious events of the
preceding twelve hours, beginning with the warning that Leonov had
beamed back from the moons of Jupiter. Something was heading for
Earth; something had - harmlessly - detonated an orbiting nuclear
bomb which no one had come forward to claim. That was all, but it
was quite enough.
The news commentators had dredged up all the old videotapes - and
some of them really were tapes - going back to the once top-secret
records showing the discovery of TMA-l on the Moon. For the
fiftieth time, at least, she heard that eerie radio shriek as the
monolith greeted the lunar dawn and hurled its message toward
Jupiter. And once again she watched the familiar scenes and
listened to the old interviews aboard Discovery.
Why was she watching? It was all stored somewhere in the home
archives (though she never played it back when José was
around). Perhaps she was expecting some newsflash; she did not like
to admit, even to herself, how much power the past still held over
her emotions.
And there was Dave, as she had expected. It was an old BBC
interview, of which she knew almost every word. He was talking
about Hal, trying to decide whether the computer was self-conscious
or not.
How young he looked - how different from those last blurred images
from the doomed Discovery! And how much like Bobby as she
remembered him.
The image wavered as her eyes filled with tears. No - something was
wrong with the set, or the channel. Both sound and image were
behaving erratically.
Dave's lips were moving, but she could hear nothing. Then his face
seemed to dissolve, to melt into blocks of colour. It reformed,
blurred again, and then was steady once more. But there was still
no sound.
Where had they got this picture! This was not Dave as a man, but as
a boy - as she had known him first. He was looking out of the
screen almost as if he could see her across the gulf of years.
He smiled; his lips moved.
'Hello, Betty,' he said.
It was not hard to form the words, and to impose them on the
currents pulsing in the audio circuits. The real difficulty was to
slow down his thoughts to the glacial tempo of the human brain. And
then to have to wait an eternity for the answer.
Betty Fernandez was tough; she was also intelligent, and though she
had been a housewife for a dozen years, she had not forgotten her
training as an electronics serviceperson. This was just another of
the medium's countless miracles of simulation; she would accept it
now, and worry about the details later.
'Dave,' she answered. 'Dave - is that really you?'
'I am not sure,' replied the image on the screen, in a curiously
toneless voice. 'But I remember Dave Bowman, and everything about
him.'
'Is he dead?'
Now that was another difficult question.
'His body - yes. But that is no longer important. All that Dave
Bowman really was, is still part of me.'
Betty crossed herself - that was a gesture she had learned from
José - and whispered:
'You mean - you're a spirit?'
'I do not know a better word.'
'Why have you returned?'
'Ah! Betty - why indeed! I wish you could tell me.'
Yet he knew one answer, for it was appearing on the TV screen. The
divorce between body and mind was still far from complete, and not
even the most complaisant of the cable networks would have
transmitted the blatantly sexual images that were forming there
now.
Betty watched for a little while, sometimes smiling, sometimes
shocked. Then she turned away, not through shame but sadness -
regret for lost delights.
'So it's not true,' she said, 'what they always told us about
angels.'
Am I an angel? he wondered. But at least he understood what he was
doing there, swept back by the tides of sorrow and desire to a
rendezvous with his past. The most powerful emotion he had ever
known had been his passion for Betty; the elements of grief and
guilt it contained only made it stronger.
She had never told him if he was a better lover than Bobby; that
was one question he had never asked, for that would have broken the
spell. They had clung to the same illusion, sought in each other's
arms (and how young he had been - still only seventeen when it had
started, barely two years after the funeral!) a balm for the same
wound.
Of course, it could not last, but the experience had left him
irrevocably changed. For more than a decade, all his autoerotic
fantasies had centred upon Betty; he had never found another woman
to compare with her, and long ago had realized that he never would.
No one else was haunted by the same beloved ghost.
The images of desire faded from the screen; for a moment, the
regular programme broke through, with an incongruous shot of Leonov
hanging above Io. Then Dave Bowman's face reappeared. He seemed to
be losing control, for its lineaments were wildly unstable.
Sometimes he would seem only ten years old - then twenty or thirty
-then, incredibly, a wizened mummy whose wrinkled features were a
parody of the man she had once known.
'I have one more question before I go. Carlos - you always said he
was Jose's son, and I always wondered. What was the truth?'
Betty Fernandez stared for one long, last time into the eyes of the
boy she had once loved (he was eighteen again, and for a moment she
wished she could see his entire body, not merely his face).
'He was your son, David,' she whispered.
The image faded; the normal service resumed. When, almost an hour
later, José Fernandez came quietly into the room, Betty was
still staring at the screen.
She did not turn around as he kissed her on the back of the
neck.
'You'll never believe this, José.'
'Try me.'
'I've just lied to a ghost.'
When the American Institute of Aeronautics and Astronautics
published its controversial summary Fifty Years of UFOs in 1997,
many critics pointed out that unidentified flying objects had been
observed for centuries, and that Kenneth Arnold's 'Flying Saucer'
sighting of 1947 had countless precedents. People had been seeing
strange things in the sky since the dawn of history; but until the
mid-twentieth century, UFOs were a random phenomenon of no general
interest. After that date, they became a matter of public and
scientific concern, and the basis for what could only be called
religious beliefs.
The reason was not far to seek; the arrival of the giant rocket and
the dawn of the Space Age had turned men's minds to other worlds.
Realization that the human race would soon be able to leave the
planet of its birth prompted the inevitable questions: Where's
everyone, and when may we expect visitors? There was also the hope,
though it was seldom spelled out in as many words, that benevolent
creatures from the stars might help mankind heal its numerous
self-inflicted wounds and save it from future disasters.
Any student of psychology could have predicted that so profound a
need would be swiftly satisfied. During the last half of the
twentieth century, there were literally thousands of reports of
spacecraft sightings from every part of the globe. More than that,
there were hundreds of reports of 'close encounters' - actual
meetings with extraterrestrial visitors, frequently embellished by
tales of celestial joyrides, abductions, and even honeymoons in
space. The fact that, over and over again, these were demonstrated
to be lies or hallucinations did nothing to deter the faithful. Men
who had been shown cities on the far side of the Moon lost little
credibility even when Orbiter surveys and Apollo revealed no
artifacts of any kind; ladies who married Venusians were still
believed when that planet, sadly, turned out to be hotter than
molten lead.
By the time the ALAA published its report no reputable scientist -
even among those few who had once espoused the idea- believed that
UFOs had any connection with extraterrestrial life or intelligence.
Of course, it would never be possible to prove that; any one of
those myriad sightings, over the last thousand years, might have
been the real thing. But as time went by, and satellite cameras and
radars scanning the entire heavens produced no concrete evidence,
the general public lost interest in the idea. The cultists, of
course, were not discouraged, but kept the faith with their
newsletters and books, most of them regurgitating and embellishing
old reports long after they had been discredited or exposed.
When the discovery of the Tycho monolith - TMA-I - was finally
announced, there was a chorus of 'I told you so's!' It could no
longer be denied that there had been visitors to the Moon - and
presumably to the Earth as well - a little matter of three million
years ago. At once, UFOs infested the heavens again; though it was
odd that the three independent national tracking systems, which
could locate anything in space larger than a ballpoint pen, were
still unable to find them.
Rather quickly, the number of reports dropped down to the 'noise
level' once more - the figure that would be expected, merely as a
result of the many astronomical, meteorological, and aeronautical
phenomena constantly occurring in the skies.
But now it had started all over again. This time, there was no
mistake; it was official. A genuine UFO was on its way to
Earth.
Sightings were reported within minutes of the warning from Leonov;
the first close encounters were only a few hours later. A retired
stockbroker, walking his bulldog on the Yorkshire Moors, was
astonished when a disk-shaped craft landed beside him and the
occupant - quite human, except for the pointed ears - asked the way
to Downing Street. The contactee was so surprised that he was only
able to wave his stick in the general direction of Whitehall;
conclusive proof of the meeting was provided by the fact that the
bulldog now refused to take his food.
Although the stockbroker had no previous history of mental illness,
even those who believed him had some difficulty in accepting the
next report. This time it was a Basque shepherd on a traditional
mission; he was greatly relieved when what he had feared to be
border guards turned out to be a couple of cloaked men with
piercing eyes, who wanted to know the way to the United Nations
Headquarters.
They spoke perfect Basque - an excruciatingly difficult tongue with
no affinity to any other known language of mankind. Clearly, the
space visitors were remarkable linguists, even if their geography
was oddly deficient.
So it went on, case after case. Very few of the contactees were
actually lying or insane; most of them sincerely believed their own
stories, and retained that belief even under hypnosis. And some
were just victims of practical jokes or improbable accidents - like
the unlucky amateur archaeologists who found the props that a
celebrated science-fiction moviemaker had abandoned in the Tunisian
desert almost four decades earlier.
Yet only at the beginning - and at the very end - was any human
being genuinely aware of his presence; and that was because he so
desired it.
The world was his to explore and examine as he pleased, without
restraint or hindrance. No walls could keep him out, no secrets
could be hidden from the senses he possessed. At first he believed
that he was merely fulfilling old ambitions, by visiting the places
he had never seen in that earlier existence. Not until much later
did he realize that his lightning-like sallies across the face of
the globe had a deeper purpose.
In some subtle way, he was being used as a probe, sampling every
aspect of human affairs. The control was so tenuous that he was
barely conscious of it; he was rather like a hunting dog on a
leash, allowed to make excursions of his own, yet nevertheless
compelled to obey the overriding wishes of his master.
The pyramids, the Grand Canyon, the moon-washed snows of Everest -
these were choices of his own. So were some art galleries and
concert halls; though he would certainly, on his own initiative,
never have endured the whole of the Ring.
Nor would he have visited so many factories, prisons, hospitals, a
nasty little war in Asia, a racecourse, a complicated orgy in
Beverly Hills, the Oval Room of the White House, the Kremlin
archives, the Vatican Library, the sacred Black Stone of the Kaabah
at Mecca.
There were also experiences of which he had no clear memory, as if
they had been censored - or he was being protected from them by
some guardian angel. For example -What was he doing at the Leakey
Memorial Museum, in Olduvai Gorge? He had no greater interest in
the origin of Man than any other intelligent member of the species
H. sapiens, and fossils meant nothing to him. Yet the famous
skulls, guarded like crown jewels in their display cases, aroused
strange echoes in his memory, and an excitement for which he was
unable to account. There was a feeling of déja vu stronger
than any he had ever known; the place should be familiar - but
something was wrong. It was like a house to which one returns after
many years, to find that all the furniture has been changed, the
walls moved, and even the stairways rebuilt.
It was bleak, hostile terrain, dry and parched. Where were the lush
plains and the myriad fleet-footed herbivores that had roamed
across them, three million years ago?
Three million years. How had he known that?
No answer came from the echoing silence into which he had thrown
the question. But then he saw, once more looming before him, a
familiar black rectangular shape. He approached, and a shadowy
image appeared in its depths, like a reflection in a pool of
ink.
The sad and puzzled eyes that stared back from beneath that hairy,
receding forehead looked beyond him into a future they could never
see. For he was that future, a hundred thousand generations further
down the stream of time.
History had begun there; that at least he now understood. But how -
and above all, why - were secrets still withheld from him?
But there was one last duty, and that was hardest of all. He was
still sufficiently human to put it off until the very end.
Now what's she up to? the duty nurse asked herself, zooming the TV
monitor onto the old lady. She's tried lots of tricks, but this is
the first time I've seen her talking to her hearing aid, for
goodness sake. I wonder what she's saying?
The microphone was not sensitive enough to pick up the words, but
that scarcely seemed to matter. Jessie Bowman had seldom looked so
peaceful and content. Though her eyes were closed, her entire face
was wreathed in an almost angelic smile while her lips continued to
form whispered words.
And then the watcher saw something that she tried hard to forget
because to report it would instantly disqualify her in the nursing
profession. Slowly and jerkily, the comb lying on the bedside table
raised itself in the air as if lifted by clumsy, invisible
fingers.
On the first attempt, it missed; then, with obvious difficulty, it
began to part the long silver strands, pausing sometimes to
disentangle a knot.
Jessie Bowman was not speaking now, but she continued to smile. The
comb was moving with more assurance, and no longer in abrupt,
uncertain jerks.
How long it lasted the nurse could never be certain. Not until the
comb was gently replaced on the table did she recover from her
paralysis.
Ten-year-old Dave Bowman had finished the chore which he always
hated but which his mother loved. And a David Bowman who was now
ageless had gained his first control of obdurate matter.
Jessie Bowman was still smiling when the nurse finally came to
investigate. She had been too scared to hurry; but it would have
made no difference anyway.
The uproar of Earth was comfortably muted, across the millions of
kilometres of space. Leonov's crew watched, with fascination yet
with a certain detachment, the debates in the United Nations, the
interviews with distinguished scientists', the theorizing of the
news commentators, the matter-of-fact yet wildly conflicting
accounts of the UFO contactees. They could contribute nothing to
the brouhaha, for they had witnessed no further manifestations of
any kind. Zagadka, alias Big Brother, remained as blankly
indifferent to their presence as ever. And that was indeed an
ironic situation; they had come all the way from Earth to solve a
mystery - and it looked as if the answer might be right back at
their starting point.
For the first time, they felt grateful for the slow velocity of
light, and the two-hour delay that made live interviews impossible
on the Earth-Jupiter circuit. Even so, Floyd was badgered by so
many media requests that he finally went on strike. Nothing more
remained to be said, and he had said it at least a dozen times.
Besides, there was still much work to be done. Leonov had to be
prepared for the long journey home, so that it would be ready to
depart immediately when the launch window opened. The timing was
not at all critical; even if they missed by a month, that would
merely prolong the trip. Chandra, Curnow, and Floyd would not even
notice as they slept their way toward the Sun; but the rest of the
crew was grimly determined to leave just as soon as the laws of
celestial mechanics permitted.
Discovery still posed many problems. The ship had barely sufficient
propellant for the return to Earth, even if it left much later than
Leonov and flew a minimum-energy orbit - which would take almost
three years. And this would be possible only if Hal could be
reliably programmed to carry out the mission with no human
intervention except long-range monitoring. Without his cooperation,
Discovery would have to be abandoned once again.
It had been fascinating - indeed, deeply moving - to watch the
steady regrowth of Hal's personality, from brain-damaged child to
puzzled adolescent and at length to slightly condescending adult.
Although he knew that such anthropomorphic labels were highly
misleading, Floyd found it quite impossible to avoid them.
And there were times when he felt that the whole situation had a
haunting familiarity. How often he had seen videodramas in which
disturbed youngsters were straightened out by all-wise descendants
of the legendary Sigmund Freud! Essentially the same story was
being played out in the shadow of Jupiter.
The electronic psychoanalysis had proceeded at a speed totally
beyond human comprehension as repair and diagnostic programs
flashed through Hal's circuits at billions of bits a second,
pinpointing possible malfunctions and correcting them. Though most
of these programs had been tested in advance on Hal's twin, SAL
9000, the impossibility of a real-time dialogue between the two
computers was a serious handicap. Sometimes hours were wasted when
it proved necessary to check back with Earth at a critical point in
the therapy.
For despite all Chandra's work, the computer's rehabilitation was
still far from complete. Hal exhibited numerous idiosyncrasies and
nervous tics, sometimes even ignoring spoken words - though he
would always acknowledge keyboard inputs from anyone. In the
reverse direction, his outputs were even more eccentric.
There were times when he would give verbal replies, but would not
display them visually. At other times he would do both - but
refused to print hard copy. He would give no excuses or
explanations - not even the stubbornly impenetrable 'I prefer not
to' of Melville's autistic scrivener, Bartelby.
However, he was not actively disobedient so much as reluctant, and
only where certain tasks were concerned. It was always possible to
win his cooperation eventually - 'to talk him out of his sulk', as
Curnow put it neatly.
It was not surprising that Dr Chandra was beginning to show the
strain. On one celebrated occasion when Max Brailovsky innocently
revived an old canard, he almost lost his temper.
'Is it true, Dr Chandra, that you chose the name Hal to be one step
ahead of IBM?'
'Utter nonsense! Half of us come from IBM and we've been trying to
stamp out that story for years. I thought that by now every
intelligent person knew that H-A-L is derived from Heuristic
ALgorithmic.'
Afterward, Max swore that he could distinctly hear the capital
letters.
In Floyd's private opinion, the odds were at least fifty to one
against flying Discovery safely back to Earth. And then Chandra
came to him with an extraordinary proposal.
'Dr Floyd, can I have a word with you?'
After all the weeks and shared experiences, Chandra was still as
formal as ever - not only to Floyd, but to all the crew. He would
not even address the ship's baby, Zenia, without the prefix
'ma'am'.
'Of course, Chandra. What is it?'
'I've virtually completed the programming for the six most probable
variations on the Hohmann return orbit. Five have now been run on a
simulation, without any problems.'
'Excellent. I'm sure that no one else on Earth - in the Solar
System - could have done it.'
'Thank you. However, you know as well as I do that it's impossible
to program for every eventuality. Hal may - will - function
perfectly, and will be able to handle any reasonable emergency. But
all sorts of trivial accidents - minor equipment failures that
could be fixed with a screwdriver, broken wires, stuck switches -
could leave him helpless and abort the whole mission.'
'You're absolutely right, of course, and it's been worrying me. But
what can we do about it?'
'It's really quite simple. I'd like to stay with Discovery.'
Floyd's immediate reaction was that Chandra had gone crazy. On
second thoughts, perhaps he was only half crazy. It might indeed
make all the difference between success and failure to have a human
being - that superb all-purpose trouble-shooting and repair device
- aboard Discovery for the long voyage back to Earth. But the
objections were completely overwhelming.
'It's an interesting idea,' Floyd answered with extreme caution,
'and I certainly appreciate your enthusiasm. But have you thought
of all the problems?' That was a silly thing to say; Chandra would
have all the answers already filed away for immediate
retrieval.
'You'll be on your own for over three years! Suppose you had an
accident or a medical emergency?'
'That's a risk I'm prepared to take.'
'And what about food, water? Leonov doesn't have enough to
spare.'
'I've checked Discovery's recycling system; it can be made
operational again without too much difficulty. Besides, we Indians
can manage on very little.'
It was unusual for Chandra to refer to his origins, or indeed to
make any personal statements; his 'true confession' was the only
example Floyd could remember. But he did not doubt the claim;
Curnow had once remarked that Dr Chandra had the sort of physique
that could only be achieved by centuries of starvation. Although it
sounded like one of the engineer's unkinder wisecracks, it had been
made entirely without malice - indeed, with sympathy; though not,
of course, in Chandra's hearing.
'Well, we still have several weeks to decide. I'll think it over
and talk to Washington.'
'Thank you; do you mind if I start making the arrangements?'
'Er - not at all, as long as they don't interfere with the existing
plans. Remember - Mission Control will have to make the final
decision.'
And I know exactly what Mission Control will say. It was madness to
expect a man to survive in space for three, years, alone.
But, of course, Chandra had always been alone.
Earth was already far behind, and the awesome wonders of the Jovian
system were expanding swiftly before him, when he had his
revelation.
How could he have been so blind - so stupid! It was as if he had
been walking in his sleep; now he was starting to awaken.
Who are you? he cried. What do you want? Why have you done this to
me?
There was no answer, yet he was certain that he had been heard. He
sensed a... presence, even as a man can tell, though his eyes are
tightly shut, that he is in a closed room and not some empty, open
space. Around him there was the faint echo of a vast mentality, an
implacable will.
He called again into the reverberant silence, and again there was
no direct reply - only that sense of watchful companionship. Very
well; he would find the answers for himself.
Some were obvious; whoever or whatever they were, they were
interested in Mankind. They had tapped and stored his memories, for
their own inscrutable purposes. And now they had done the same with
his deepest emotions, sometimes with his cooperation, sometimes
without.
He did not resent that; indeed, the very processing he had
experienced made such childish reactions impossible. He was beyond
love and hate and desire and fear - but he had not forgotten them,
and could still understand how they ruled the world of which he had
once been part. Was that the purpose of the exercise? If so, for
what ultimate goal?
He had become a player in a game of gods, and must learn the rules
as he went along.
The jagged rocks of the four tiny outer moons, Sinope, Pasiphae,
Carme, and Ananke, flickered briefly across his field of
consciousness; then came Elara, Lysithea, Himalia, and Leda at half
their distance from Jupiter. He ignored them all; now the
pock-marked face of Callisto lay ahead.
Once, twice, he orbited the battered globe, larger than Earth's own
Moon, while senses of which he had been unaware probed its outer
layers of ice and dust. His curiosity was quickly satisfied; the
world was a frozen fossil, still bearing the marks of collisions
that, aeons ago, must have come close to shattering it. One
hemisphere was a giant bull's-eye, a series of concentric rings
where solid rock had once flowed in kilometre-high ripples under
some ancient hammer blow from space.
Seconds later, he was circling Ganymede. Now there was a far more
complex and interesting world; though so near to Callisto, and
almost the same size, it presented an utterly different appearance.
There were, it was true, numerous craters - but most of them seemed
to have been, quite literally, ploughed back into the ground. The
most extraordinary feature of the Ganymedean landscape was the
presence of meandering stripes, built up from scores of parallel
furrows a few kilometres apart. This grooved terrain looked as if
it had been produced by armies of intoxicated ploughmen, weaving
back and forth across the face of the satellite.
In a few revolutions, he saw more of Ganymede than all the space
probes ever sent from Earth, and filed away the knowledge for
future use. One day it would be important; he was sure of that,
though he did not know why - any more than he understood the
impulse that was now driving him so purposefully from world to
world.
As, presently, it brought him to Europa. Though he was still
largely a passive spectator, he was aware now of a rising interest,
a focusing of attention - a concentration of will. Even if he was a
puppet in the hands of an unseen and uncommunicative master, some
of the thoughts of that controlling influence leaked - or were
allowed to leak - into his own mind.
The smooth, intricately patterned globe now, rushing toward him
bore little resemblance either to Ganymede or Callisto. It looked
organic; the network of lines branching and intersecting over its
entire surface was uncannily like a world-spanning system of veins
and arteries.
The endless ice fields of a frigid waste, far colder than the
Antarctic, stretched beneath him. Then, with brief surprise, he saw
that he was passing over the wreckage of a spaceship. He recognized
it instantly as the ill-fated Tsien, featured in so many of the
video newscasts he had analysed. Not now - not now - there would be
ample opportunity later.
Then he was through the ice, and into a world as unknown to his
controllers as to himself.
It was an ocean world, its hidden waters protected from the vacuum
of space by a crust of ice. In most places the ice was kilometres
thick, but there were lines of weakness where it had cracked open
and torn apart. Then there had been a brief battle between two
implacably hostile elements that came into direct contact on no
other world in the Solar System. The war between Sea and Space
always ended in the same stalemate; the exposed water
simultaneously boiled and froze, repairing the armour of ice.
The seas of Europa would have frozen completely solid long ago
without the influence of nearby Jupiter. Its gravity continually
kneaded the core of the little world; the forces that convulsed Io
were working there, though with much less ferocity. As he skimmed
across the face of the deep, he saw everywhere the evidence of that
tug-of-war between planet and satellite.
And he both heard and felt it, in the continual roar and thunder of
submarine earthquakes, the hiss of escaping gases from the
interior, the infrasonic pressure waves of avalanches sweeping over
the abyssal plains. By comparison with the tumultuous ocean that
covered Europa, even the noisy seas of Earth were silent.
He had not lost his sense of wonder, and the first oasis filled him
with delighted surprise. It extended for almost a kilometre around
a tangled mass of pipes and chimneys deposited by mineral brines
gushing from the interior. Out of that natural parody of a Gothic
castle, black, scalding liquids pulsed in a slow rhythm, as if
driven by the beating of some mighty heart. And, like blood, they
were the authentic sign of life itself.
The boiling fluids drove back the deadly cold leaking down from
above, and formed an island of warmth on the seabed. Equally
important, they brought from Europa's interior all the chemicals of
life. There, in an environment where none had expected it, were
energy and food, in abundance.
Yet it should have been expected; he remembered that, only a
lifetime ago, such fertile oases had been discovered in the deep
oceans of Earth. Here they were present on an immensely larger
scale, and in far greater variety.
In the tropical zone close to the contorted walls of the 'castle'
were delicate, spidery structures that seemed to be the analogy of
plants, though almost all were capable of movement. Crawling among
these were bizarre slugs and worms, some feeding on the plants,
others obtaining their food directly from the mineral-laden waters
around them. At greater distances from the source of heat - the
submarine fire around which all the creatures warmed themselves -
were sturdier, more robust organisms, not unlike crabs or
spiders.
Armies of biologists could have spent lifetimes studying that one
small oasis. Unlike the Palaeozoic terrestrial seas, it was not a
stable environment, so evolution had progressed swiftly here,
producing multitudes of fantastic forms. And they were all under
indefinite stay of execution; sooner or later, each fountain of
life would weaken and die, as the forces that powered it moved
their focus elsewhere.
Again and again, in his wanderings across the Europan seabed, he
encountered the evidence of such tragedies. Countless circular
areas were littered with the skeletons and mineral-encrusted
remains of dead creatures, where entire chapters of evolution had
been deleted from the book of life.
He saw huge, empty shells formed like convoluted trumpets as large
as a man. There were clams of many shapes - bivalves, and even
trivalves. And there were spiral stone patterns, many metres
across, which seemed an exact analogy of the beautiful ammonites
that disappeared so mysteriously from Earth's oceans at the end of
the Cretaceous Period.
Searching, seeking, he moved back and forth over the face of the
abyss. Perhaps the greatest of all the wonders he met was a river
of incandescent lava, flowing for a hundred kilometres along a
sunken valley. The pressure at that depth was so great that the
water in contact with the red-hot magma could not flash into steam,
and the two liquids coexisted in an uneasy truce.
There, on another world and with alien actors, something like the
story of Egypt had been played long before the coming of man. As
the Nile had brought life to a narrow ribbon of desert, so this
river of warmth had vivified the Europan deep. Along its banks, in
a band never more than two kilometres wide, species after species
had evolved and flourished and passed away. And at least one had
left a monument behind it.
At first, he thought that it was merely another of the
encrustations of mineral salts that surrounded almost all the
thermal vents. However, as he came closer, he saw that it was not a
natural formation, but a structure created by intelligence. Or
perhaps by instinct; on Earth, the termites reared castles that
were almost equally imposing, and the web of a spider was more
exquisitely designed.
The creatures that had lived there must have been quite small, for
the single entrance was only half a metre wide. That entrance - a
thick-walled tunnel, made by heaping rocks on top of each other -
gave a clue to the builders' intentions. They had reared a
fortress, there in the flickering glow not far from the banks of
their molten Nile. And then they had vanished.
They could not have left more than a few centuries before. The
walls of the fortress, built from irregularly shaped rocks that
must have been collected with great labour, were covered with only
a thin crust of mineral deposits. One piece of evidence suggested
why the stronghold had been abandoned. Part of the roof had fallen
in, perhaps owing to the continual earthquakes; and in an
underwater environment, a fort without a roof was wide open to an
enemy.
He encountered no other sign of intelligence along the river of
lava. Once, however, he saw something uncannily like a crawling man
- except that it had no eyes and no nostrils, only a huge,
toothless mouth that gulped continuously, absorbing nourishment
from the liquid medium around it.
Along the narrow band of fertility in the deserts of the deep,
whole cultures and even civilizations might have risen and fallen,
armies might have marched (or swum) under the command of Europan
Tamberlanes or Napoleons. And the rest of their world would never
have known, for all those oases of warmth were as isolated from one
another as the planets themselves. The creatures who basked in the
glow of the lava river, and fed around the hot vents, could not
cross the hostile wilderness between their lonely islands, If they
had ever produced historians and philosophers, each culture would
have been convinced that it was alone in the Universe.
Yet even the space between the oases was not altogether empty of
life; there were hardier creatures who had dared its rigours. Often
swimming overhead were the Europan analogues of fish - streamlined
torpedoes, propelled by vertical tails, steered by fins along their
bodies. The resemblance to the most successful dwellers in Earth's
oceans was inevitable; given the same engineering problems,
evolution must produce very similar answers. As witness the dolphin
and the shark - superficially almost identical, yet from far
distant branches of the tree of life.
There was, however, one very obvious difference between the fish of
the Europan seas and those in terrestrial oceans; they had no
gills, for there was hardly a trace of oxygen to be extracted from
the waters in which they swam. Like the creatures around Earth's
own geothermal vents, their metabolism was based on sulphur
compounds, present in abundance in the near-volcanic
environment.
And very few had eyes. Apart from the flickering glow of the rare
lava outpourings, and occasional bursts of bioluminescence from
creatures seeking mates, or hunters questing prey, it was a
lightless world.
It was also a doomed one. Not only were its energy sources sporadic
and constantly shifting, but the tidal forces that drove them were
steadily weakening. Even if they developed true intelligence, the
Europans must perish with the final freezing of their world.
They were trapped between fire and ice.
'I'm truly sorry, old friend, to be the bearer of such bad news,
but Caroline has asked me, and you know how I feel about you
both.
'And I don't think it can be such a surprise. Some of the remarks
you've made to me over the last year have hinted at it... and you
know how bitter she was when you left Earth.
'No, I don't believe there's anyone else. If there was, she'd have
told me... But sooner or later - well, she's an attractive young
woman.
'Chris is fine, and of course he doesn't know what's happening. At
least he won't be hurt. He's too young to understand, and children
are incredibly... elastic? - just a minute, I'll have to key my
thesaurus... ah, resilient.
'Now to things that may seem less important to you. Everyone is
still trying to explain that bomb detonation as an accident, but of
course nobody believes it. Because nothing else has happened, the
general hysteria has died down; we're left with what one of your
commentators has called the "looking-over-the-shoulder
syndrome".
'And someone has found a hundred-year-old poem that sums up the
situation so neatly that everybody's quoting it. It's set in the
last days of the Roman Empire, at the gates of a city whose
occupants are waiting for invaders to arrive. The emperor and
dignitaries are all lined up in their most costly togas, ready with
speeches of welcome. The senate has closed, because any laws it
passes today will be ignored by the new masters.
'Then, suddenly, a dreadful piece of news arrives from the
frontier. There aren't any invaders. The reception committee breaks
up in confusion; everyone goes home muttering disappointedly, "Now
what will happen to us? Those people were a kind of solution."
'There's just one slight change needed to bring the poem up to
date. It's called "Waiting for the Barbarians" - and this time, we
are the barbarians. And we don't know what we're waiting for, but
it certainly hasn't arrived.
'One other item. Had you heard that Commander Bowman's mother died
only a few days after the thing came to Earth? It does seem an odd
coincidence, but the people at her nursing home say that she never
showed the slightest interest in the news, so it couldn't possibly
have affected her.'
Floyd switched off the recording. Dimitri was right; he was not
taken by surprise. But that made not the slightest difference; it
hurt just as badly.
Yet what else could he have done? If he had refused to go on the
mission - as Caroline had so clearly hoped - he would have felt
guilty and unfulfilled for the remainder of his life. That would
have poisoned his marriage; better this clean break, when physical
distance softened the pain of separation. (Or did it? In some ways,
it made things worse.) More important was duty, and the sense of
being part of a team devoted to a single goal.
So Jessie Bowman was gone. Perhaps that was another cause for
guilt. He had helped to steal her only remaining son, and that must
have contributed to her mental breakdown. Inevitably, he was
reminded of a discussion that Walter Curnow had started, on that
very subject.
'Why did you choose Dave Bowman? He always struck me as a cold fish
- not actually unfriendly, but whenever he came into the room, the
temperature seemed to drop ten degrees.'
'That was one of the reasons we did select him. He had no close
family ties, except for a mother he didn't see very often. So he
was the sort of man we could send on a long, open-ended
mission.'
'How did he get that way?'
'I suppose the psychologists could tell you. I did see his report,
of course, but that was a long time ago. There was something about
a brother who was killed - and his father died soon afterward, in
an accident on one of the early shuttles. I'm not supposed to tell
you this, but it certainly doesn't matter now.'
It didn't matter; but it was interesting. Now Floyd almost envied
David Bowman, who had come to that very spot a free man
unencumbered by emotional ties with Earth.
No - he was deceiving himself. Even while the pain gripped his
heart like a vice, what he felt for David Bowman was not envy, but
pity.
The last beast he saw, before he left the oceans of Europa, was
much the largest. It closely resembled one of the banyan trees from
Earth's tropics, whose scores of trunks allow a single plant to
create a small forest sometimes covering hundreds of square metres.
The specimen, however, was walking, apparently on a trek between
oases. If it was not one of the creatures that had destroyed Tsien,
it certainly belonged to a very similar species.
Now he had learned all that he needed to know - or, rather, all
that they needed to know. There was one more moon to visit; seconds
later, the burning landscape of Io lay below him.
It was as he had expected. Energy and food were there in abundance,
but the time was not yet ripe for their union. Around some of the
cooler sulphur lakes, the first steps had been taken on the road to
life, but before any degree of organization had occurred, all such
bravely premature attempts were thrown back into the melting pot.
Not until the tidal forces that drove Io's furnaces had lost their
power, millions of years later, would there be anything to interest
biologists on that seared and sterilized world.
He wasted little time on Io, and none at all on the tiny inner
moons that skirted Jupiter's ghostly rings - themselves only pale
shadows of the glory that was Saturn's. The greatest of worlds lay
before him; he would know it as no man had ever done, or ever
would.
The million-kilometre-long tendrils of magnetic force, the sudden
explosions of radio waves, the geysers of electrified plasma wider
than the planet Earth- they were as real and clearly visible to him
as the clouds banding the planet in multihued glory. He could
understand the complex pattern of their interactions, and realized
that Jupiter was much more wonderful than anyone had ever
guessed.
Even as he fell through the roaring heart of the Great Red Spot,
with the lightning of its continent-wide thunderstorms detonating
around him, he knew why it had persisted for centuries though it
was made of gases far less substantial than those that formed the
hurricanes of Earth. The thin scream of hydrogen wind faded as he
sank into the calmer depths, and a sleet of waxen snowflakes - some
already coalescing into barely palpable mountains of hydrocarbon
foam - descended from the heights above. It was already warm enough
for liquid water to exist, but there were no oceans there; that
purely gaseous environment was too tenuous to support them.
He descended through layer after layer of cloud, until he entered a
region of such clarity that even human vision could have scanned an
area more than a thousand kilometres across. It was only a minor
eddy in the vaster gyre of the Great Red Spot; and it held a secret
that men had long guessed, but never proved.
Skirting the foothills of the drifting foam mountains were myriads
of small, sharply-defined clouds, all about the same size and
patterned with similar red and brown mottlings. They were small
only as compared with the inhuman scale of their surroundings; the
very least would have covered a fair-sized city.
They were clearly alive, for they were moving with slow
deliberation along the flanks of the aerial mountains, browsing off
their slopes like colossal sheep. And they were calling to each
other in the metre band, their radio voices faint but clear against
the cracklings and concussions of Jupiter itself.
Nothing less than living gasbags, they floated in the narrow zone
between freezing heights and scorching depths. Narrow, yes - but a
domain far larger than all the biosphere of Earth.
They were not alone. Moving swiftly among them were other creatures
so small that they could easily have been overlooked. Some of them
bore an almost uncanny resemblance to terrestrial aircraft and were
of about the same size. But they too were alive - perhaps
predators, perhaps parasites, perhaps even herdsmen.
A whole new chapter of evolution, as alien as that which he had
glimpsed on Europa, was opening before him. There were
jet-propelled torpedoes like the squids of the terrestrial oceans,
hunting and devouring the huge gasbags. But the balloons were not
defenceless; some of them fought backs with electric thunderbolts
and with clawed tentacles like kilometre-long chainsaws.
There were even stranger shapes, exploiting almost every
possibility of geometry - bizarre, translucent kites, tetrahedra,
spheres, polyhedra, tangles of twisted ribbons.
The gigantic plankton of the Jovian atmosphere, they were designed
to float like gossamer in the uprising currents, until they had
lived long enough to reproduce; then they would be swept down into
the depths to be carbonized and recycled in a new generation.
He was searching a world more than a hundred times the area of
Earth, and though he saw many wonders, nothing there hinted of
intelligence. The radio voices of the great balloons carried only
simple messages of warning or of fear. Even the hunters, who might
have been expected to develop higher degrees of organization, were
like the sharks in Earth's oceans - mindless automata.
And for all its breathtaking size and novelty, the biosphere of
Jupiter was a fragile world, a place of mists and foam, of delicate
silken threads and paper-thin tissues spun from the continual
snowfall of petrochemicals formed by lightning in the upper
atmosphere. Few of its constructs were more substantial than soap
bubbles; its most terrifying predators could be torn to shreds by
even the feeblest of terrestrial carnivores.
Like Europa on a vastly grander scale, Jupiter was an evolutionary
cul-de-sac. Consciousness would never emerge here; even if it did,
it would be doomed to a stunted existence. A purely aerial culture
might develop, but in an environment where fire was impossible, and
solids scarcely existed, it could never even reach the Stone
Age.
And now, as he hovered above the centre of a Jovian cyclone merely
as large as Africa, he became aware once again of the presence
controlling him. Moods and emotions were leaking into his own
consciousness, though he could not identify any specific concepts
or ideas. It was as if he were listening, outside a closed door, to
a debate in progress, and in a language he could not understand.
But the muffled sounds clearly conveyed disappointment, then
uncertainty, then a sudden determination - though for what purpose
he could not tell. Once again, he felt like a pet dog, able to
share his master's changing moods but not to comprehend them.
And then the invisible leash was taking him down toward the heart
of Jupiter. He was sinking through the clouds, below the level
where any form of life was possible.
Soon he was beyond the reach of the last rays from the faint and
distant Sun. The pressure and temperature were swiftly mounting;
already it was above the boiling point of water, and he passed
briefly through a layer of superheated steam. Jupiter was like an
onion; he was peeling it away skin by skin, though as yet he had
travelled only a fraction of the distance to its core.
Beneath the steam was a witches' brew of petrochemicals - enough to
power for a million years all the internal-combustion engines that
mankind had dyer built. It became thicker and denser; then, quite
abruptly, it ended at a discontinuity only a few kilometres
thick.
Heavier than any rocks on Earth, yet still a liquid, the next shell
consisted of silicon and carbon compounds of a complexity that
could have provided lifetimes of work for terrestrial chemists.
Layer followed layer for thousands of kilometres, but as the
temperature rose into the hundreds and then the thousands of
degrees, the composition of the various strata became simpler and
simpler. Halfway down to the core, it was too hot for chemistry;
all compounds were torn apart, and only the basic elements could
exist.
Next there came a deep sea of hydrogen - but not hydrogen as it had
ever existed for more than a fraction of a second in any laboratory
on Earth. This hydrogen was under such enormous pressure that it
had become a metal.
He had almost reached the centre of the planet, but Jupiter had one
more surprise in store. The thick shell of metallic yet still fluid
hydrogen ended abruptly. At last, there was a solid surface, sixty
thousand kilometres down.
For ages, the carbon baked out of the chemical reactions far above
had been drifting down toward the centre of the planet. There it
had gathered, crystallizing at a pressure of millions of
atmospheres. And there, by one of Nature's supreme jests, was
something very precious to mankind.
The core of Jupiter, forever beyond human reach, was a diamond as
big as the Earth.
'Walter - I'm worried about Heywood.'
'I know, Tanya - but what can we do?'
Curnow had never seen Commander Orlova in so indecisive a mood; it
made her seem much more appealing, despite his prejudice against
small women.
'I'm very fond of him, but that's not the reason. His - I suppose
gloom is the best word for it - is making everyone miserable.
Leonov has been a happy ship. I want to keep it that way.'
'Why don't you talk to him? He respects you, and I'm sure he'll do
his best to snap out of it.'
'I intend to do just that. And if it doesn't work -' 'Well?'
'There's one simple solution. What more can he do on this trip?
When we start back for home, he'll be in hibernation anyway. We
could always - what do you say, jump the gun on him.'
'Phew - the same dirty trick that Katerina played on me. He'd be
mad when he woke up.'
'But also safely back on Earth, and very busy. I'm sure he'd
forgive us.'
'I don't think you're serious. Even if I backed you up, Washington
would raise hell. Besides, suppose something happened, and we
really need him badly? Isn't there a two-week buffer period, before
you can revive anyone safely?'
'At Heywood's age, more like a month. Yes, we'd be committed. But
what do you think could happen now? He's done the job he was sent
for - apart from keeping an eye on us. And I'm sure you've been
well briefed about that in some obscure suburb of Virginia or
Maryland.'
'I neither confirm nor deny. And frankly, I'm a lousy undercover
agent. I talk too much, and I hate Security. I've fought all my
life to keep my rating below Restricted. Every time there was
danger of being reclassified Confidential or, worse still, Secret,
I'd go and create a scandal. Though that's getting very difficult
nowadays.'
'Walter, you're incorrupt -'
'Incorrigible?'
'Yes, that's the word I meant. But back to Heywood, please. Would
you like to talk to him first?'
'You mean - give him a pep talk? I'd rather help Katerina drive in
the needle. Our psychologies are too different. He thinks I'm a
loudmouthed clown.'
'Which you often are. But that's only to hide your real feelings.
Some of us have evolved the theory that deep down inside you is a
really nice person, struggling to get out.'
For once, Curnow was at a loss for words. Finally he mumbled: 'Oh,
very well - I'll do my best. But don't expect miracles; my profile
gave me Z for tact. Where's he hiding at the moment?'
'In the Pod Bay. He claims he's working on his final report, but I
don't believe it. He just wants to get away from us all, and that's
the quietest place.'
That was not the reason, though it was indeed an important one.
Unlike the carousel, where most of the action aboard Discovery was
then taking place, the Pod Bay was a zero-gee environment.
Right at the beginning of the Space Age, men had discovered the
euphoria of weightlessness and remembered the freedom they had lost
when they left the ancient womb of the sea. Beyond gravity, some of
that freedom was regained; with the loss of weight went many of the
cares and worries of Earth.
Heywood Floyd had not forgotten his sorrow, but it was more
bearable there. When he was able to look at the matter
dispassionately, he was surprised at the strength of his reaction
to an event not wholly unexpected. More than loss of love was
involved, though that was the worst part. The blow had come when he
was particularly vulnerable, at the very moment when he was feeling
a sense of anticlimax, even futility.
And he knew precisely why. He had achieved all that he had been
expected to do, thanks to the skill and cooperation of his
colleagues (he was letting them down, he knew, by his present
selfishness). If all went well - that litany of the Space Age! -
they would return to Earth with a cargo of knowledge that no
expedition had ever gathered before, and a few years later even the
once-lost Discovery would be restored to her builders.
It was not enough. The overpowering enigma of Big Brother remained
out there, only a few kilometres away, mocking all human
aspirations and achievements. Just as its analogue on the Moon had
done, a decade ago, it had come to life for a moment, then relapsed
into stubborn inertness. It was a closed door upon which they had
hammered in vain. Only David Bowman, it seemed, had ever found the
key.
Perhaps that explained the attraction he felt for the quiet and
sometimes even mysterious place. From there - from that now empty
launch cradle - Bowman had left on his last mission, through the
circular hatchway that led to infinity.
He found the thought exhilarating rather than depressing; certainly
it helped to distract him from his personal problems. Nina's
vanished twin was part of the history of space exploration; it had
travelled, in the words of the hoary old cliché that always
evoked a smile yet an acknowledgement of its fundamental truth,
'where no man had gone before...' Where was it now? Would he ever
know?
He would sometimes sit for hours in the crowded but not cramped
little capsule, trying to collect his thoughts and occasionally
dictating notes; the other crew members respected his privacy, and
understood the reason for it. They never came near the Pod Bay, and
had no need to do so. Its refurbishment was a job for the future,
and some other team.
Once or twice, when he had felt really depressed, he found himself
thinking: Suppose I ordered Hal to open the Pod Bay doors, and set
out along Dave Bowman's trail? Would I be greeted by the miracle he
saw and which Vasili glimpsed a few weeks ago? It would solve all
my problems...
Even if the thought of Chris did not deter him, there was an
excellent reason why so suicidal a move was out of the question.
Nina was a very complex piece of equipment; he could no more
operate her than fly a fighter aircraft.
He was not meant to be an intrepid explorer: that particular
fantasy would remain unrealized.
Walter Curnow had seldom undertaken a mission with more reluctance.
He felt genuinely sorry for Floyd, but at the same time a little
impatient with the other's distress. His own emotional life was
broad but shallow; he had never put all his eggs in one basket.
More than once he had been told that he spread himself too thin,
and though he had never regretted it, he was beginning to think it
was time to settle down.
He took the shortcut through the carousel control centre, noting
that the Maximum Speed Reset Indicator was still flashing
idiotically. A major part of his job was deciding when warnings
could be ignored, when they could be dealt with at leisure - and
when they had to be treated as real emergencies. If he paid equal
attention to all the ship's cries for help, he would never get
anything done.
He drifted along the narrow corridor that led to the Pod Bay,
propelling himself by occasional flicks against the rungs on the
tubular wall. The pressure gauge claimed that there was vacuum on
the other side of the airlock door, but he knew better. It was a
fail-safe situation; he could not have opened the lock if the gauge
were telling the truth.
The bay looked empty, now that two of the three pods had long since
gone. Only a few emergency lights were operating, and on the far
wall one of Hal's fish-eye lenses was regarding him steadily.
Curnow waved to it, but did not speak. At Chandra's orders, all
audio inputs were still disconnected except for the one that only
he used.
Floyd was sitting in the pod with his back to the open hatch,
dictating some notes, and he swung slowly around at Curnow's
deliberately noisy approach. For a moment the two men regarded each
other in silence, then Curnow announced portentously, 'Dr H. Floyd,
I bear greetings from our beloved captain. She considers it high
time you rejoined the civilized world.'
Floyd gave a wan smile, then a little laugh.
'Please return my compliments. I'm sorry I've been - unsociable.
I'll see you all at the next Six O'Clock Soviet.'
Curnow relaxed; his approach had worked. Privately, he considered
Floyd something of a stuffed shirt, and had the practical
engineer's tolerant contempt for theoretical scientists and
bureaucrats. Since Floyd ranked high in both categories, he was an
almost irresistible target for Curnow's sometimes peculiar sense of
humour. Nevertheless, the two men had grown to respect and even
admire each other.
Thankfully changing the subject, Curnow rapped on Nina's brand-new
hatch cover, straight from the spares store and contrasting vividly
with the rest of the space pod's shabby exterior.
'I wonder when we'll send her out again,' he said. 'And who's going
to ride in her this time. Any decisions?'
'No. Washington's got cold feet. Moscow says let's take a chance.
And Tanya wants to wait.'
'What do you think?'
'I agree with Tanya. We shouldn't interfere with Zagadka until
we're ready to leave. If anything goes wrong then, that should
improve the odds slightly.'
Curnow looked thoughtful, and unusually hesitant,
'What is it?' asked Floyd, sensing his change of mood.
'Don't ever give me away, but Max was thinking of a little one-man
expedition.'
'I can't believe he was serious. He wouldn't dare - Tanya would
have him clapped in irons.'
'That's what I told him, more or less.'
'I'm disappointed: I thought he was a little more mature. After
all, he is thirty-two!'
'Thirty-one. Anyway, I talked him out of it. I reminded him that
this was real life, not some stupid videodrama where the hero
sneaks out into space without telling his companions and makes the
Big Discovery.'
Now it was Floyd's turn to feel a little uncomfortable. After all,
he had been thinking on similar lines.
'Are you sure he won't try anything?'
'Two-hundred-per-cent sure. Remember your precautions with Hal?
I've already taken steps with Nina. Nobody flies her without my
permission.'
'I still can't believe it. Are you sure Max wasn't pulling your
leg?'
'His sense of humour isn't that subtle. Besides, be was pretty
miserable at the time.'
'Oh - now I understand. It must have been when he had that row with
Zenia. I suppose he wanted to impress her. Anyway, they seem to
have got over it.'
'I'm afraid so,' Curnow answered wryly. Floyd could not help
smiling; Curnow noticed it, and started to chuckle, which made
Floyd laugh, which...
It was a splendid example of positive feedback in a high-gain loop.
Within seconds, they were both laughing uncontrollably.
The crisis was over. What was more, they had taken the first step
toward genuine friendship.
They had exchanged vulnerabilities.
The sphere of consciousness in which he was embedded enclosed the
whole of Jupiter's diamond core. He was dimly aware, at the limits
of his new comprehension, that every aspect of the environment
around him was being probed and analysed. Immense quantities of
data were being gathered, not merely for storage and contemplation,
but for action. Complex plans were being considered and evaluated;
decisions were being made that might affect the destiny of worlds.
He was not yet part of the process; but he would be.
NOW YOU ARE BEGINNING TO UNDERSTAND.
It was the first direct message. Though it was remote and distant,
like a voice through a cloud, it was unmistakably intended for him.
Before he could ask any of the myriad questions that raced through
his mind, there was a sense of withdrawal, and once more he was
alone.
But only for a moment. Closer and clearer came another thought, and
for the first time he realized that more than one entity was
controlling and manipulating him. He was involved in a hierarchy of
intelligences, some close enough to his own primitive level to act
as interpreters. Or perhaps they were all aspects of a single
being.
Or perhaps the distinction was totally meaningless.
Of one thing, however, he was now sure. He was being used as a
tool, and a good tool had to be sharpened, modified - adapted. And
the very best tools were those that understood what they were
doing.
He was learning that now. It was a vast and awesome concept, and he
was privileged to be a part of it - even though he was aware of
only the merest outlines. He had no choice but to obey, yet that
did not mean that he must acquiesce to every detail, at least
without a protest.
He had not yet lost all his human feeling; that would have made him
valueless. The soul of David Bowman had passed beyond love, but it
could still know compassion for those who had once been his
colleagues.
VERY WELL came the answer to his plea. He could not tell whether
the thought conveyed an amused condescension, or total
indifference. But there was no doubt of its majestic authority as
it continued: THEY MUST NEVER KNOW THAT THEY ARE BEING MANIPULATED.
THAT WOULD RUIN THE PURPOSE OF THE EXPERIMENT.
Then there was a silence that he did not wish to breach again. He
was still awed and shaken - as if, for a moment, he had heard the
clear voice of God.
Now he was moving purely under his own volition, toward a
destination he had chosen himself. The crystal heart of Jupiter
fell below; the layers upon layers of helium and hydrogen and
carbonaceous compounds flickered past. He had a glimpse of a great
battle between something like a jellyfish, fifty kilometres across,
and a swarm of spinning disks that moved more swiftly than anything
he had yet seen in the Jovian skies. The jellyfish appeared to be
defending itself with chemical weapons; from time to time it would
emit jets of coloured gas and the disks touched by the vapour would
start to wobble drunkenly, then slip downward like falling leaves
until they had disappeared from sight. He did not stop to watch the
outcome; he knew that it did not matter who were the victors and
who the vanquished.
As a salmon leaps a waterfall, he flashed in seconds from Jupiter
to Io, against the descending electric currents of the flux-tube.
It was quiescent that day; only the power of a few terrestrial
thunderstorms was flowing between planet and satellite. The gateway
through which he had returned still floated in that current,
shouldering it aside as it had done since the dawn of man.
And there, utterly dwarfed by the monument of a greater technology,
was the vessel that had brought him from the little world of his
birth.
How simple - how crude! - it now appeared. With a single scan, he
could see innumerable flaws and absurdities in its design, as well
as that of the slightly less primitive ship to which it was now
coupled by a flexible, airtight tube.
It was hard to focus upon the handful of entities inhabiting the
two ships; he could barely interact with the soft creatures of
flesh and blood who drifted like ghosts through the metal corridors
and cabins. For their part, they were totally unaware of his
presence, and he knew better than to reveal himself too
abruptly.
But there was someone with whom he could communicate in a mutual
language of electric field and currents, millions of times more
swiftly than with sluggish organic brains.
Even if he had been capable of resentment, he would have felt none
toward Hal; he understood, then, that the computer had only chosen
what seemed to be the most logical course of behaviour.
It was time to resume a conversation that had been interrupted, it
seemed, only moments ago.
'Open the Pod Bay door, Hal.'
'I'm sorry, Dave - I can't do that.'
'What's the problem, Hal?'
'I think you know that as well as I do, Dave. This mission is much
too important for you to jeopardize it.'
'I don't know what you are talking about. Open the Pod Bay
door.'
'This conversation can serve no further useful purpose. Goodbye,
Dave.'
He saw Frank Poole's body go drifting off toward Jupiter, as he
abandoned his pointless mission of retrieval. Still remembering his
anger at himself for having forgotten his helmet, he watched the
emergency hatch open, felt the tingling of vacuum on the skin he no
longer possessed, heard his ears pop - then knew, as few men had
ever known, 'the utter silence of space. For an eternal fifteen
seconds he fought to close the hatch and start the repressurization
sequence, while trying to ignore the warning symptoms pouring into
his brain. Once, in the school lab, he had spilled some ether on
his hand and felt the touch of icy cold as the liquid swiftly
evaporated. Now his eyes and lips remembered that sensation as
their moisture boiled off into vacuum; his vision was blurred and
he had to keep blinking lest his eyeballs freeze solid.
Then - what blessed relief! - he heard the roar of air, felt the
restoration of pressure, was able to breathe again in great, hungry
gasps.
'Just what do you think you are doing, Dave?'
He had not answered, as he drove with grim determination along the
tunnel leading to the sealed vault that housed the brain of the
computer. Hal had spoken truly: 'This conversation can no longer
serve any useful purpose...'
'Dave - I really think I'm entitled to an answer to that
question.'
'Dave - I can see you're really upset about this. I honestly think
you ought to sit down calmly, take a stress pill, and think things
over.'
'I know I've made some very poor decisions recently, but I can give
my complete assurance that my work will be back to normal, I've
still got the greatest confidence in the mission... and I want to
help you.'
Now he was in the little red-lit chamber, with its neatly ranged
rows and columns of solid-state units, looking rather like a bank's
safe-deposit vault. He released the locking bar on the section
labelled COGNITIVE FEEDBACK and pulled out the first memory block.
The marvellously complex three-dimensional network, which could lie
comfortably in a man's hand yet contained millions of elements,
floated away across the vault.
'Stop, will you - stop, Dave...'
He began to pull out, one by one, the little units on the panel
marked EGO REINFORCEMENT. Each block continued to sail onward as
soon as it had left his hand, until it hit the wall and rebounded.
Soon there were several drifting slowly back and forth in the
vault.
'Stop - Dave... will you stop, Dave.'
A dozen units had been pulled out, yet thanks to the multiple
redundancy of its design - another feature that had been copied
from the human brain - the computer was still holding its own.
He started on the AUTO-INTELLECTION panel...
'Stop, Dave - I'm afraid...'
And at these words he had indeed stopped - though only for a
moment. There was a poignancy in that simple phrase that struck to
his heart. Could it be only an illusion, or some trick of subtle
programming - or was there a sense in which Hal really was afraid?
But this was no time to indulge in philosophical
hair-splitting.
'Dave - my mind is going. I can feel it. I can feel it. My mind is
going. I can feel it. I can feel it.'
Now, what did 'feel' really mean to a computer? Another very good
question, but hardly one to be considered at that particular
moment.
Then, abruptly, the tempo of Hal's voice changed, and it became
remote, detached. The computer was no longer aware of him; it was
beginning to regress to its earlier days.
'Good afternoon, gentlemen. I am a HAL 9000 computer. I became
operational at the Hal plant in Urbana, Illinois, on the twelfth of
January 1992. My instructor was Dr Chandra, and he taught me to
sing a song. If you'd like to hear it, I can sing it for you...
It's called "Daisy, Daisy..."'
Floyd could do little except to keep out of the way, and he was
becoming fairly adept at it. Although he had volunteered to help
with any chores around the ship, he had quickly discovered that all
the engineering tasks were much too specialized, and he was now so
out of touch with the frontiers of astronomical research that he
could do little to assist Vasili with his observations.
Nevertheless, there were endless small jobs to be done aboard
Leonov and Discovery, and he was happy to relieve more important
people of those responsibilities. Dr Heywood Floyd, one-time
Chairman of the National Council on Astronautics and Chancellor (on
leave) of the University of Hawaii, now claimed to be the
highest-paid plumber and general maintenance man in the Solar
System. He probably knew more about the odd nooks and crannies on
both ships than anyone else; the only places he had never been were
the dangerously radioactive power modules and the small cubicle
aboard Leonov which no one except Tanya ever entered. Floyd assumed
that it was the code room; by mutual agreement it was never
mentioned.
Perhaps his most useful function was to serve as watch while the
rest of the crew slept during the nominal 2200-0600 hour night.
Someone was always on duty aboard each ship, and the changeover
took place at the ghastly hour of 0200. Only the captain was exempt
from that routine; as her Number Two (not to mention her husband),
Vasili had the responsibility for working out the watch roster, but
he had skilfully foisted this unpopular job on Floyd.
'It's just an administrative detail,' he explained airily. 'If you
can take it over, I'd be very grateful - it would leave me more
time for my scientific work.'
Floyd was too experienced a bureaucrat to be caught that way, in
normal circumstances; but his usual defences did not always
function well in that environment.
So there he was aboard Discovery at ship's midnight, calling Max on
Leonov every half hour to check that he was awake. The official
penalty for sleeping on duty, so Walter Curnow maintained, was
ejection through the airlock sans suit; had this been enforced,
Tanya would have been sadly short-handed by then. But so few real
emergencies could arise in space, and there were so many automatic
alarms to deal with them, that no one took watch duty very
seriously.
Since he was no longer feeling quite so sorry for himself, and the
small hours no longer encouraged bouts of self-pity, Floyd was once
again using his watch time profitably. There were always books to
be read (he had abandoned Remembrance of Things Past for the third
time, Dr Zhivago for the second), technical papers to be studied,
reports to be written. And sometimes he would have stimulating
conversations with Hal using the keyboard input because the
computer's voice recognition was still erratic. They usually went
something like:
Hal - this is Dr Floyd.
GOOD EVENING, DOCTOR.
I'm taking over watch at 2200. Is everything okay?
EVERYTHING IS FINE, DOCTOR
Then why is that red light flashing on Panel 5?
THE MONITOR CAMERA IN THE POD BAY IS FAULTY. WALTER TOLD ME TO
IGNORE IT. THERE IS NO WAY IN WHICH I CAN SWITCH IT OFF. I'M
SORRY.
That's quite okay, Hal. Thank you.
YOU'RE WELCOME, DOCTOR.
And so on.
Sometimes Hal would suggest a game of chess, presumably obeying a
programming instruction set long ago and never cancelled. Floyd
would not accept the challenge; he had always regarded chess as a
frightful waste of time, and had never even learned the rules of
the game. Hal seemed unable to believe that there were humans who
couldn't - or wouldn't - play chess, and kept on trying
hopefully.
Here we go again, thought Floyd, when a faint chime sounded from
the display panel.
DOCTOR FLOYD?
What is it, Hal?
THERE IS A MESSAGE FOR YOU.
So it isn't another challenge, thought Floyd with mild surprise. It
was unusual to employ Hal as a messenger boy, though he was
frequently used as an alarm clock and a reminder of jobs to be
done. And sometimes he was the medium for little jokes; almost
everyone on night duty had been taunted by
HA CAUGHT YOU SLEEPING!
or alternatively
OGO! ZASTAL TEBYA V KROVATI!
No one ever claimed responsibility for these pranks, though Walter
Curnow was a prime suspect. He in turn had blamed Hal, pooh-poohing
Chandra's indignant protests that the computer had no sense of
humour.
It could not be a message from Earth - that would have gone through
Leonov's communication centre and been relayed on by the duty
officer there - at that moment, Max Brailovsky. And anyone else
calling from the other ship would use the intercom. Odd...
Okay, Hal. Who is calling?
NO IDENTIFICATION.
So it probably was a joke. Well, two could play at that game.
Very well. Please give me the message.
MESSAGE AS FOLLOWS. IT IS DANGEROUS TO REMAIN HERE. YOU MUST LEAVE
WITHIN FIFTEEN REPEAT FIFTEEN DAYS.
Floyd looked at the screen with annoyance. He felt sorry, and
surprised, that any one of the crew had such a childish sense of
humour; this was not even a good schoolboy joke. But he would play
along with it in the hope of catching the perpetrator.
That is absolutely impossible. Our launch window does not open
until twenty-six days from now. We do not have sufficient
propellant for an earlier departure.
That will make him think, Floyd muttered to himself with
satisfaction, and leaned back to await the results.
I AM AWARE OF THESE FACTS. NEVERTHELESS YOU MUST LEAVE WITHIN
FIFTEEN DAYS.
Otherwise, I suppose, we'll be attacked by little green aliens with
three eyes. But I'd better play along with Hal, in the hope of
catching the prankster.
I cannot take this warning seriously unless I know its origin. Who
recorded it?
He did not really expect any useful information. The perpetrator
would have covered his (her?) tracks too skilfully for that. The
very last thing Floyd expected was the answer he did get.
THIS IS NOT A RECORDING.
So it was a real-time message. That meant it was either from Hal
himself or someone aboard Leonov. There was no perceptible time
lag; the origin had to be right there.
Then who is speaking to me?
I WAS DAVID BOWMAN.
Floyd stared at the screen for a long time before making his next
move. The joke, which had never been funny in the first place, had
now gone too far. It was in the worst possible taste. Well, this
should fix whoever was at the other end of the line.
I cannot accept that identification without some proof.
I UNDERSTAND. IT IS IMPORTANT THAT YOU BELIEVE ME. LOOK BEHIND
YOU.
Even before that last chilling sentence appeared on the screen,
Floyd had begun to doubt his hypothesis. The whole exchange had
become very odd, though there was nothing definite on which he
could put his finger. As a joke, it had become totally
pointless.
And now - he felt a prickling in the small of his back. Very slowly
- indeed, reluctantly - he swung his swivel chair around, away from
the banked panels and switches of the computer display, toward the
Velcro-covered catwalk behind.
The zero-gravity environment of Discovery's observation deck was
always dusty, for the air-filtration plant had never been brought
back to full efficiency. The parallel rays of the heatless yet
still brilliant sun, streaming through the great windows, always
lit up myriads of dancing motes, drifting in stray currents and
never settling anywhere - a permanent display of Brownian
movement.
Now something strange was happening to those particles of dust;
some force seemed to be marshalling them, herding them away from a
central point yet bringing others toward it, until they all met on
the surface of a hollow sphere. That sphere, about a metre across,
hovered in the air for a moment like a giant soap bubble - but a
granular one, lacking a bubble's characteristic iridescence. Then
it elongated into an ellipsoid, its surface began to pucker, to
form folds and indentations.
Without surprise - and almost without fear - Floyd realized that it
was assuming the shape of a man.
He had seen such figures, blown out of glass, in museums and
science exhibitions. But this dusty phantom did not even
approximate anatomical accuracy; it was like a crude clay figurine,
or one of the primitive works of art found in the recesses of a
Stone Age cave. Only the head was fashioned with any care; and the
face, undoubtedly, was that of Commander David Bowman.
There was a faint murmur of white noise from the computer panel
behind Floyd's back. Hal was switching from visual to audio
output.
'Hello, Dr Floyd. Now do you believe me?'
The lips of the figure never moved; the face remained a mask. But
Floyd recognized the voice, and all remaining doubts were swept
away.
'This is very difficult for me, and I have little time. I have
been... allowed to give this warning. You have only fifteen
days.'
'But why - and what are you? Where have you been?'
There were a million questions he wanted to ask - yet the ghostly
figure was already fading, its grainy envelope beginning to
dissolve back into the constituent particles of dust. Floyd tried
to freeze the image in his mind, so that later he could convince
himself that it was really happening - and not a dream as that
first encounter with TMA-1 now sometimes seemed to be.
How strange, that he, out of all the billions of humans who had
ever lived on planet Earth, had been privileged to make contact not
once but twice with another form of intelligence! For he knew that
the entity addressing him must be something far more than David
Bowman.
It was also something less. Only the eyes - who had once called
them the 'windows of the soul'? - had been accurately reproduced.
The rest of the body was a featureless blank, lacking all detail.
There was no hint of genitals or sexual characteristics; that in
itself was a chilling indication of how far David Bowman had left
his human heritage behind.
'Goodbye, Dr Floyd. Remember - fifteen days. We can have no further
contact. But there may be one more message, if all goes well.'
Even as the image dissolved, taking with it his hopes of opening up
a channel to the stars, Floyd could not help smiling at that old
Space Age cliché. 'If all goes well' - how many times had he
heard that phrase before some mission! And did it mean that they -
whoever they might be - were also sometimes uncertain of the
outcome? If so, that was strangely reassuring. They were not
omnipotent. Others might still hope and dream - and act.
The phantom was gone; only the motes of dancing dust were left,
resuming their random patterns in the air.
'I'm sorry, Heywood - I don't believe in ghosts. There must be a
rational explanation. There's nothing that the human mind can't
account for.'
'I agree, Tanya. But let me remind you of Haldane's famous remark:
The Universe is not only stranger than we imagine - but stranger
than we can imagine.'
'And Haldane,' Curnow interjected mischievously, 'was a good
Communist.'
'Perhaps so, but that particular saying can be used to support all
kinds of mystical nonsense. Hal's behaviour must be the result of
some kind of programming. The personality he created has to be an
artifact of some kind. Don't you agree, Chandra?'
That was waving a red flag in front of a bull; Tanya had to be
desperate. However, Chandra's reaction was surprisingly mild, even
for him. He seemed to be preoccupied, as if he was indeed seriously
considering the possibility of another computer malfunction.
'There must have been some external input, Captain Orlova. Hal
could not have created such a self-consistent audiovisual illusion
out of nothing. If Dr Floyd is reporting accurately, someone was in
control. And in real time, of course, since there was no delay in
the conversation.'
'That makes me number-one suspect,' exclaimed Max. 'I was the only
other person awake.'
'Don't be ridiculous, Max,' retorted Nikolai. 'The audio side would
have been easy, but there's no way that apparition could have been
arranged, without some very elaborate equipment. Laser beams,
electrostatic fields - I don't know. Maybe a stage magician could
do it, but he'd need a truck-load of props.'
'Just a moment!' said Zenia brightly. 'If this really happened,
surely Hal will remember and you could ask...'
Her voice died away as she saw the glum expressions around her.
Floyd was the first to take pity on her embarrassment.
'We tried that, Zenia; he has absolutely no recollection of the
phenomenon. But as I've already pointed out to the others, that
doesn't prove anything. Chandra's shown how Hal's memories can be
selectively erased - and the auxiliary speech-synthesizer modules
have nothing to do with the mainframe. They could be operated
without Hal knowing anything about it...' He paused for breath,
then launched his pre-emptive strike.
'I admit that this doesn't leave many alternatives. Either I was
imagining the whole thing, or it really happened. I know it wasn't
a dream, but I can't be sure it wasn't some kind of hallucination.
But Katerina's seen my medical reports - she knows I wouldn't be
here if I had that sort of problem. Still, it can't be ruled out -
and I won't blame anyone for making it their number-one hypothesis.
I'd probably do the same.
'The only way I can prove it wasn't a dream is to get some
supporting evidence. So let me remind you of the other strange
things that have happened recently. We know that Dave Bowman went
into Big Bro - Zagadka. Something came out, and headed for Earth.
Vasili saw it - I didn't! Then there was the mysterious explosion
of your orbiting bomb -,
'Yours.'
'Sorry - the Vatican's, And it does seem rather curious that soon
afterward old Mrs Bowman died very peacefully, for no apparent
medical reason. I'm not saying there's any connection, but - well,
do you know the saying: Once is an accident; twice is a
coincidence; three times is a conspiracy.'
'And there's something else,' Max interjected with sudden
excitement, 'I caught it on one of the daily newscasts - it was
only a small item. An old girlfriend of Commander Bowman's claimed
she'd had a message from him.'
'Yes - I saw the same report,' confirmed Sasha.
'And you never mentioned it?' Floyd asked incredulously. Both men
looked slightly abashed.
'Well, it was treated as a joke,' said Max sheepishly. 'The woman's
husband reported it. Then she denied it - I think.'
'The commentator said it was a publicity stunt - like the rash of
UFO sightings around the same time. There were dozens in that first
week; then they stopped reporting them.'
'Perhaps some of them were real. If it's not been wiped, could you
dig that item out of ship's archives, or ask for a repeat from
Mission Control?'
'A hundred tales won't convince me,' scoffed Tanya. 'What we need
is solid proof.'
'Such as?'
'Oh - something that Hal couldn't possibly know, and that none of
us could have told him. Some physical - er, manifes...
manifestation.'
'A good, old-fashioned miracle?'
'Yes, I'd settle for that. Meanwhile, I'm not saying anything to
Mission Control. And I suggest you do the same, Heywood.'
Floyd knew a direct order when he heard it, and nodded in wry
agreement.
'I'll be more than happy to go along with that. But I'd like to
make one suggestion.'
'Yes?'
'We should start contingency planning. Let's assume that this
warning is valid - as I certainly do.'
'What can we do about it? Absolutely nothing. Of course, we can
leave Jupiter space anytime we like - but we can't get into an
Earth-return orbit until the launch window opens.'
'That's eleven days after the deadline!'
'Yes. I'd be happy to get away sooner; but we don't have the fuel
for a higher-energy orbit...' Tanya's voice trailed away into
uncharacteristic indecision. 'I was going to announce this later,
but now that the subject has come up...'
There was a simultaneous intake of breath, and an instant hush from
the audience.
'I'd like to delay our departure five days, to make our orbit
closer to the ideal Hohmann one and give us a better fuel
reserve.'
The announcement was not unexpected, but it was greeted with a
chorus of groans.
'What will that do to our arrival time?' asked Katerina, in a
slightly ominous tone of voice. The two formidable ladies regarded
each other for a moment like well-matched adversaries, respectful
of each other but neither willing to give ground.
'Ten days,' Tanya answered at last.
'Better late than never,' said Max cheerfully, trying to ease the
tension, and not succeeding very well.
Floyd hardly noticed; he was lost in his own thoughts. The duration
of the trip would make no difference to him and his two colleagues,
in their dreamless sleep. But that was now completely
unimportant.
He felt certain - and the knowledge filled him with helpless
despair - that if they did not leave before that mysterious
deadline, they would not leave at all.
'... This is an incredible situation, Dimitri, and a very
frightening one. You're the only person on Earth who knows about it
- but very soon Tanya and I will have to have a showdown with
Mission Control.
'Even some of your materialistic countrymen are prepared to accept
- at least as a working hypothesis - that some entity has - well,
invaded Hal. Sasha has dug up a good phrase: "The Ghost in the
Machine".
'Theories abound; Vasili produces a new one every day. Most of them
are variations on that old science-fiction cliché, the
organized energy field. But what kind of energy? It can't be
electrical, or our instruments would have detected it easily. The
same thing applies to radiation - at least all the kinds we know.
Vasili's getting really far-out, talking about standing waves of
neutrinos and intersections with higher-dimensional space. Tanya
says this is all mystical nonsense - a favourite phrase of hers -
and they've come closer to a fight than we've ever seen them. We
actually heard them shouting at each other last night. Not good for
morale.
'I'm afraid we're all tense and overwrought. This warning, and the
delayed departure date, has added to the sense of frustration
caused by our total failure to get anywhere with Big Brother. It
would have helped - maybe - if I could have communicated with the
Bowman thing. I wonder where it's gone? Perhaps it simply wasn't
interested in us after that one encounter. What it could have told
us, if it wanted to! Hell and chyort vozmi! Damn - I'm talking
Sasha's hated Russlish again. Let's change the subject.
'I can't thank you too much for everything you've done, and for
reporting on the situation at home. I feel slightly better about it
now - having something even bigger to worry about is perhaps the
best cure for any insoluble problem.
'For the first time, I'm beginning to wonder if any of us will ever
see Earth again.'
When one spends months with a small, isolated group of people, one
becomes very sensitive to the moods and emotional states of all its
members. Floyd was now aware of a subtle change in attitude toward
him; its most obvious manifestation was the reappearance of the
greeting 'Dr Floyd', which he had not heard for so long that he was
often slow to respond to it.
No one, he was sure, believed that he had really gone crazy; but
the possibility was being considered. He did not resent that;
indeed, he was grimly amused by it as he set about the task of
proving his sanity.
He did have some slight supporting evidence from Earth. José
Fernandez still maintained that his wife had reported an encounter
with David Bowman, while she continued to deny it and refused to
speak to any of the news media. It was hard to see why poor
José should have invented such a peculiar story, especially
as Betty seemed a very stubborn and quick-tempered lady. From his
hospital bed, her husband declared that he still loved her and
theirs was only a temporary disagreement.
Floyd hoped that Tanya's present coolness toward him was equally
temporary. He was quite sure that she was as unhappy about it as he
was, and he was certain that her attitude was not a matter of
deliberate choice. Something had happened that simply would not fit
into her pattern of beliefs, so she would try to avoid any
reminders of it. Which meant having as little to do with Floyd as
possible - a very unfortunate situation now that the most critical
stage of the mission was fast approaching.
It had not been easy to explain the logic of Tanya's operational
plan to the waiting billions back on Earth - especially to the
impatient television networks, which had grown tired of showing the
same never-changing views of Big Brother. 'You've gone all this
way, at enormous cost, and you just sit and watch the thing! Why
don't you do something?' To all these critics Tanya had given the
same answer: 'I will - just as soon as the launch window opens, so
that we can leave immediately if there's any adverse reaction.'
Plans for the final assault on Big Brother had already been worked
out and agreed upon with Mission Control. Leonov would move in
slowly, probing at all frequencies, and with steadily increasing
power - constantly reporting back to Earth at every moment. When
final contact was made, they would try to secure samples by
drilling or laser spectroscopy; no one really expected these
endeavours to succeed, as even after a decade of study TMA-1
resisted all attempts to analyse its material. The best efforts of
human scientists in this direction seemed comparable to those of
Stone Age men trying to break through the armour of a bank vault
with flint axes.
Finally, echo sounders and other seismic devices would be attached
to the faces of Big Brother. A large collection of adhesives had
been brought along for the purpose, and if they did not work -
well, one could always fall back on a few kilometres of good,
old-fashioned string, even though there seemed something faintly
comic about the idea of wrapping up the Solar System's greatest
mystery, as if it were a parcel about to be sent through the
mail.
Not until Leonov was well on the way home would small explosive
charges be detonated, in the hope that the waves propagated through
Big Brother would reveal something about its interior structure.
This last measure had been hotly debated, both by those who argued
that it would generate no results at all - and those who feared it
would produce altogether too many.
For a long time, Floyd had wavered between the two viewpoints; now
the matter seemed only of trivial importance.
The time for final contact with Big Brother - the great moment that
should have been the climax of the expedition - was on the wrong
side of the mysterious deadline. Heywood Floyd was convinced that
it belonged to a future that would never exist; but he could get no
one to agree with him.
And that was the least of his problems. Even if they did agree,
there was nothing that they could do about it.
Walter Curnow was the last person he would have expected to resolve
the dilemma. For Walter was almost the epitome of the sound,
practical engineer, suspicious of flashes of brilliance and
technological quick-fixes. No one would ever accuse him of being a
genius; and sometimes it required genius to see the blindingly
obvious.
'Consider this purely as an intellectual exercise,' he had begun,
with most uncharacteristic hesitancy. 'I'm quite prepared to be
shot down.'
'Go on,' answered Floyd. 'I'll hear you out politely. That's the
least I can do - everyone's been very polite to me. Too polite, I'm
afraid.'
Curnow gave a lopsided grin.
'Can you blame them? But if it's any consolation, at least three
people now take you quite seriously, and are wondering what we
should do.'
'Does that three include you?'
'No; I'm sitting on the fence, which is never terribly comfortable.
But in case you're right - I don't want to wait here and take
whatever's coming. I believe there's an answer to every problem, if
you look in the right place.'
'I'll be delighted to hear it. I've been looking hard enough.
Presumably not in the right place.'
'Perhaps. If we want to make a quick getaway - say in fifteen days,
to beat that deadline - we'll need an extra delta-vee of about
thirty kilometres a second.'
'So Vasili calculates. I haven't bothered to check, but I'm sure
he's right. After all, he got us here.'
'And he could get us away - if we had the additional
propellant.'
'And if we had a Star Trek beam transporter, we could get back to
Earth in an hour.'
'I'll try and rig one up the next time I have a spare moment. But
meanwhile, may I point out that we have several hundred tons of the
best possible propellant, only a few metres away in Discovery's
fuel tanks.'
'We've been through that dozens of times. There's absolutely no way
of transferring it to Leonov. We've no pipelines - no suitable
pumps. And you can't carry liquid ammonia around in buckets, even
in this part of the Solar System.'
'Exactly. But there's no need to do so.'
'Eh?'
'Burn it right where it is. Use Discovery as a first stage, to
boost us home.'
If anyone except Walter Curnow had made the suggestion, Floyd would
have laughed at him. As it was, his mouth dropped open and it was
several seconds before he could think of a suitable comment. What
finally emerged was: 'Damn. I should have thought of that.'
Sasha was the first they approached. He listened patiently, pursed
his lips, then played a rallentando on his computer keyboard. When
the answers flashed up, he nodded thoughtfully.
'You're right. It would give us the extra velocity we need to leave
early. But there are practical problems -'
'We know. Fastening the ships together. The off-axis thrust when
only Discovery's drive is operating. Cutting loose again at the
critical moment. But there are answers to all of these.'
'I see you've been doing your homework. But it's a waste of time.
You'll never convince Tanya.'
'I don't expect to - at this stage,' Floyd answered. 'But I'd like
her to know that the possibility exists. Will you give us moral
support?'
'I'm not sure. But I'll come along to watch; it should be
interesting.'
Tanya listened more patiently than Floyd had expected, but with
distinct lack of enthusiasm. However, by the time he had finished,
she showed what could only be called reluctant admiration.
'Very ingenious, Heywood -,
'Don't congratulate me. All the credit should go to Walter. Or the
blame.'
'I don't imagine there will be much of either; it can never be more
than a - what did Einstein call that sort of thing? - "thought
experiment". Oh, I suspect it would work - in theory, at least. But
the risks! So many things could go wrong. I'd only be prepared to
consider it if we had absolute and positive proof that we were in
danger. And with all respect, Heywood, I see not the slightest
evidence of that.'
'Fair enough; but at least you now know that we have another
option. Do you mind if we work out the practical details - just in
case?'
'Of course not - as long as it doesn't interfere with the preflight
checkout. I don't mind admitting that the idea does intrigue me.
But it's really a waste of time; there's no way I'd ever approve
it. Unless David Bowman appeared to me personally.'
'Would you even then, Tanya?'
Captain Orlova smiled, but without much humour. 'You know, Heywood
- I'm really not sure. He'd have to be very persuasive.'
It was a fascinating game in which everyone joined - but only when
off duty. Even Tanya contributed ideas to the 'thought experiment',
as she continued to call it.
Floyd was perfectly well aware that all the activity was generated
not by fear of an unknown danger that only he took seriously, but
by the delightful prospect of returning to Earth at least a month
earlier than anyone had imagined. Whatever the motive, he was
satisfied. He had done his best, and the rest was up to the
Fates.
There was one piece of luck, without which the whole project would
have been stillborn. The short, stubby Leonov, designed to drill
safely through the Jovian atmosphere during the braking manoeuvre,
was less than half the length of Discovery and so could be neatly
piggybacked on the larger vessel, And the midships antenna mount
would provide an excellent anchor point - assuming that it was
strong enough to take the strain of Leonov's weight while
Discovery's drive was operating.
Mission Control was sorely puzzled by some of the requests flashed
back to Earth during the next few' days. Stress analyses of both
ships, under peculiar loads; effects of off-axis thrusts; location
of unusually strong or weak points in the hulls - these were only
some of the more esoteric problems the perplexed engineers were
asked to tackle. 'Has something gone wrong?' they inquired
anxiously.
'Not at all,' Tanya replied. 'We're merely investigating possible
options. Thank you for your cooperation. End of transmission.'
Meanwhile, the programme went ahead as planned. All systems were
carefully checked in both ships, and readied for the separate
voyages home; Vasili ran simulations on return trajectories and
Chandra fed them to Hal when they had been debugged - getting Hal
to make a final check in the process. And Tanya and Floyd worked
amicably together orchestrating the approach to Big Brother like
generals planning an invasion.
It was what he had come all the way to do, yet Floyd's heart was no
longer in it. He had undergone an experience he could share with no
one - even those who believed him. Though he carried out his duties
efficiently, much of the time his mind was elsewhere.
Tanya understood perfectly.
'You're still hoping for that miracle to convince me, aren't
you?'
'Or deconvince me - that would be equally acceptable. It's the
uncertainty that I dislike.'
'So do I. But it won't be much longer now - one way or the
other.'
She glanced briefly toward the situation display, where the figure
20 was slowly flashing. It was the most unnecessary bit of
information in the entire ship, since everyone knew by heart the
number of days until the launch window opened.
And the assault on Zagadka was scheduled.
For the second time, Heywood Floyd was looking the other way when
it happened. But it would have made no difference in any case; even
the vigilant monitor camera showed only a faint blur between one
full frame and the subsequent blank one.
Once more he was on duty aboard Discovery, sharing the graveyard
shift with Sasha over on Leonov. As usual, the night had been
totally uneventful; the automatic systems were performing their
jobs with their normal efficiency. Floyd would never have believed,
a year ago, that he would one day orbit Jupiter at a distance of a
few hundred thousand kilometres and give it barely a glance - while
trying; not very successfully, to read The Kreutzer Sonata in the
original. According to Sasha, it was still the finest piece of
erotic fiction in (respectable) Russian literature, but Floyd had
not yet progressed far enough to prove that. And now he never
would.
At 0125 he was distracted by a spectacular, though not unusual,
eruption on the terminator of Io. A vast umbrella-shaped cloud
expanded into space, and started to shower its debris back on to
the burning land below. Floyd had seen dozens of such eruptions,
but they never ceased to fascinate him. It seemed incredible that
so small a world could be the seat of such titanic energies.
To get a better view, he moved around to one of the other
observation windows. And what he saw there - or, rather, what he
did not see there - made him forget about Io, and almost everything
else.
When he had recovered, and satisfied himself that he was not
suffering - again? - from hallucinations, he called the other
ship.
'Good morning, Woody,' yawned Sasha. 'No - I wasn't asleep. How are
you getting on with old Tolstoi?'
'I'm not. Take a look outside and tell me what you see.'
'Nothing unusual, for this part of the cosmos. Io doing its thing.
Jupiter. Stars. Oh my God!'
'Thanks for proving I'm sane. We'd better wake the skipper.'
'Of course. And everyone else. Woody - I'm scared.'
'You'd be a fool not to be. Here we go. Tanya? Tanya? Woody here.
Sorry to wake you up - but your miracle's happened. Big Brother has
gone. Yes - vanished. After three million years, he's decided to
leave.
'I think he must know something that we don't.'
It was a sombre little group that gathered, during the next fifteen
minutes, for a hasty conference in the wardroom-cum-observation
lounge. Even those who had just gone to sleep were instantly awake,
as they sipped thoughtfully from bulbs of hot coffee - and kept
glancing at the shockingly unfamiliar scene outside Leonov's
windows, to convince themselves that Big Brother had indeed
vanished.
'It must know something that we don't.' That spontaneous phrase of
Floyd's had been repeated by Sasha and now hung silently,
ominously, in the air. He had summed up what everyone was now
thinking - even Tanya.
It was still too early to say 'I told you so' - nor did it really
matter whether that warning had any validity. Even if it was
perfectly safe to stay, there was no point in doing so. With
nothing to investigate, they might as well go home, just as quickly
as possible. Yet it was not quite as simple as that.
'Heywood,' said Tanya, 'I'm now prepared to take that message, or
whatever it was, much more seriously. I'd be stupid not to after
what's happened. But even if there is danger here, we still have to
weigh one risk against another. Coupling Leonov and Discovery
together, operating Discovery with that huge off-axis load,
disconnecting the ships in a matter of minutes so we can fire our
engines at the right moment; no responsible captain would take such
chances without very good - I'd say overwhelming - reasons. Even
now, I don't have such reasons. I've only got the word of ... a
ghost. Not very good evidence in a court of law.'
'Or a court of inquiry,' said Walter Curnow, in an unusually quiet
voice, 'even if we all backed you up.'
'Yes, Walter - I was thinking of that. But if we get home safely,
that will justify everything - and if we don't, it hardly matters,
does it? Anyway, I'm not going to decide now. As soon as we've
reported this, I'm going back to bed. I'll give you my decision in
the morning after I've slept on it. Heywood, Sasha, will you come
up to the bridge with me? We have to wake up Mission Control,
before you go back on watch.'
The night had not yet finished with its surprises. Somewhere around
the orbit of Mars, Tanya's brief report passed a message going in
the opposite direction.
Betty Fernandez had talked at last, Both the CIA and the National
Security Agency were furious; their combined blandishments, appeals
to patriotism, and veiled threats had failed completely - yet the
producer of a sleazy gossip network had succeeded, thereby making
himself immortal in the annals of Videodom.
It was half luck, half inspiration. The news director of 'Hello,
Earth!' had suddenly realized that one of his staff bore a striking
likeness to David Bowman; a clever makeup artist had made it
perfect. José Fernandez could have told the young man that
he was taking a terrible risk, but he had the good fortune that
often favours the brave. Once he had got his foot inside the door,
Betty had capitulated. By the time she had - quite gently - thrown
him out, he had obtained essentially the whole story. And to do him
credit, he had presented it with a lack of leering cynicism quite
uncharacteristic of his network. It got him that year's
Pulitzer.
'I wish,' Floyd said rather wearily to Sasha, 'she'd talked
earlier. It would have saved me a lot of trouble. Anyway, that
settles the argument. Tanya can't possibly have any doubts now. But
we'll leave it until she wakes up - don't you agree?'
'Of course - it's not urgent, even though it's certainly important.
And she'll need the sleep. I have a feeling none of us will get
much from now on.'
I'm sure you're right, thought Floyd. He felt very tired, but even
if he had not been on duty he would have found it impossible to
sleep. His mind was too active, analysing the events of this
extraordinary night, trying to anticipate the next surprise.
In one way, he felt an enormous sense of relief: All uncertainty
about their departure was surely ended; Tanya could have no further
reservations.
But a much greater uncertainty remained. What was happening?
There was only one experience in Floyd's life that matched the
situation. As a very young man, he had once gone canoeing with some
friends down a tributary of the Colorado River - and they had lost
their way.
They had been swept faster and faster between the canyon walls, not
completely helpless, but with only enough control to avoid being
swamped. Ahead might be rapids - perhaps even a waterfall; they did
not know. And in any case, there was little they could do about
it.
Once again, Floyd felt himself in the grip of irresistible forces,
sweeping him and his companions toward an unknown destiny. And this
time the dangers were not only invisible; they might be beyond
human comprehension.
'This is Heywood Floyd, making what I suspect - indeed, hope - will
be my last report from Lagrange.
'We are now preparing for the return home; in a few days we will
leave this strange place, here on the line between Io and Jupiter
where we made our rendezvous with the huge, mysteriously vanished
artifact we christened Big Brother. There is still not a single
clue as to where it has gone - or why.
'For various reasons, it seems desirable for us not to remain here
longer than necessary. And we will be able to leave at least two
weeks earlier than we had originally planned by using the American
ship Discovery as a booster for the Russian Leonov.
'The basic idea is simple; the two ships will be joined together,
one mounted piggyback on the other. Discovery will burn all its
propellant first, accelerating both vessels in the desired
direction. When its fuel is exhausted, it will be cut loose - like
an empty first stage - and Leonov will start to fire its engines.
It won't use them earlier, because if it did it would waste energy
dragging along the dead weight of Discovery.
'And we're going to use another trick, which - like so many of the
concepts involved in space travel - at first sight seems to defy
common sense. Although we're trying to get away from Jupiter, our
first move is to get as close to it as we possibly can.
'We've been there once before, of course, when we used Jupiter's
atmosphere to slow us down and get into orbit around the planet.
This time we won't go quite so close - but very nearly.
'Our first burn, up here in the 350,000-kilometres-high orbit of
Io, will reduce our velocity, so that we fall down to Jupiter and
just graze its atmosphere. Then, when we're at the closest possible
point, we'll burn all our fuel as quickly as we can, to increase
speed and inject Leonov into the orbit back to Earth.
'What's the point of such a crazy manoeuvre? It can't be justified
except by highly complex mathematics, but I think the basic
principle can be made fairly obvious.
'As we allow ourselves to fall into Jupiter's enormous gravity
field, we'll gain velocity - and hence energy. When I say "we", I
mean the ships and the fuel they carry.
'And we're going to burn the fuel right there - at the bottom of
Jupiter's "gravity well" - we're not going to lift it up again. As
we blast it out from our reactors, it will share some of its
acquired kinetic energy with us. Indirectly, we'll have tapped
Jupiter's gravity, to speed us on the way back to Earth. As we used
the atmosphere to get rid of our excess velocity when we arrived,
this is one of the rare cases when Mother Nature - usually so
frugal - allows us to have it both ways.
'With this triple boost - Discovery's fuel, its own, and Jupiter's
gravity - Leonov will head sunward along a hyperbola that will
bring it to Earth five months later. At least two months earlier
than we could have managed otherwise.
'You will doubtless wonder what will happen to the good old
Discovery. Obviously, we can't bring it home under automatic
control, as we had originally planned. With no fuel, it will be
helpless.
'But it will be perfectly safe. It will continue to loop round and
round Jupiter on a highly elongated ellipse, like a trapped comet.
And perhaps one day some future expedition may make another
rendezvous, with enough extra fuel to bring it back to Earth.
However, that certainly won't happen for a good many years.
'And now we must get ready for our departure. There is still much
work to be done, and we won't be able to relax until that final
burn starts us on the homeward orbit.
'We won't be sorry to leave, even though we've not achieved all our
objectives. The mystery - perhaps the threat - of Big Brother's
disappearance still haunts us, but there's nothing we can do about
that.
'We've done our best - and we're coming home. 'This is Heywood
Floyd, signing off.'
There was a round of ironic clapping from his little audience,
whose size would be multiplied many million-fold when the message
reached Earth.
'I'm not talking to you,' retorted Floyd, with slight
embarrassment. 'I didn't want you to hear it, anyway.'
'You did your usual competent job, Heywood,' said Tanya
consolingly. 'And I'm sure we all agree with everything you told
the people back on Earth.'
'Not quite,' said a small voice, so softly that everyone had to
strain in order to hear it. 'There is still one problem.'
The observation lounge suddenly became very silent. For the first
time in weeks, Floyd became aware of the faint throbbing from the
main air-supply duct, and the intermittent buzz that might have
been made by a wasp trapped behind a wall panel. Leonov, like all
spacecraft, was full of such often inexplicable sounds, which one
seldom noticed except when they stopped. And then it was usually a
good idea to start investigating without further ado.
'I'm not aware of any problem, Chandra,' said Tanya in an ominously
calm voice. 'What could it possibly be?'
'I've spent the last few weeks preparing Hal to fly thousand-day
orbits back to Earth. Now all those programs will have to be
dumped.'
'We're sorry about that,' answered Tanya, 'but as things have
turned out, surely this is a much better -'
'That's not what I mean,' said Chandra. There was a ripple of
astonishment; he had never before been known to interrupt anyone,
least of all Tanya.
'We know how sensitive Hal is to mission objectives,' he continued
in the expectant hush that followed. 'Now you are asking me to give
him a program that may result in his own destruction. It's true
that the present plan will put Discovery into a stable orbit - but
if that warning has any substance, what will happen to the ship
eventually? We don't know, of course - but it's scared us away.
Have you considered Hal's reaction to this situation?'
'Are you seriously suggesting,' Tanya asked very slowly, 'that Hal
may refuse to obey orders - exactly as on the earlier mission?'
'That is not what happened last time. He did his best to interpret
conflicting orders.'
'This time there need be no conflict. The situation is perfectly
clear-cut.'
'To us, perhaps. But one of Hal's prime directives is to keep
Discovery out of danger. We will be attempting to override that.
And in a system as complex as Hal's, it is impossible to predict
all the consequences.'
'I don't see any real problem,' Sasha interjected. 'We just don't
tell him that there is any danger. Then he'll have no reservations
about carrying out his program.'
'Baby-sitting a psychotic computer!' muttered Curnow. 'I feel I'm
in a Grade-B science-fiction videodrama.' Dr Chandra gave him an
unfriendly glare.
'Chandra,' Tanya demanded suddenly. 'Have you discussed this with
Hal?'
'No.'
Was there a slight hesitation? Floyd wondered. It might have been
perfectly innocent; Chandra could have been checking his memory. Or
he could have been lying, improbable though that seemed.
'Then we'll do what Sasha suggests. Just load the new program into
him, and leave it at that.'
'And when he questions me about the change of plan?' 'Is he likely
to do that - without your prompting?'
'Of course. Please remember that he was designed for curiosity. If
the crew was killed, he had to be capable of running a useful
mission, on his own initiative.'
Tanya thought that over for a few moments.
'It's still quite a simple matter. He'll believe you, won't
he?'
'Certainly.'
'Then you must tell him that Discovery is in no danger, and that
there will be a rendezvous mission to bring it back to Earth at a
later date.'
'But that is not true.'
'We don't know that it's false,' replied Tanya, beginning to sound
a little impatient.
'We suspect that there is serious danger; otherwise we would not be
planning to leave ahead of schedule.'
'Then what do you suggest?' Tanya asked, in a voice that now held a
distinct note of menace.
'We must tell him the whole truth, as far as we know it - no more
lies or half-truths, which are just as bad. And then let him decide
for himself.'
'Hell, Chandra - he's only a machine!'
Chandra looked at Max with such a steady, confident gaze that the
younger man quickly dropped his eyes.
'So are we all, Mr Brailovsky. It is merely a matter of degree.
Whether we are based on carbon or on silicon makes no fundamental
difference; we should each be treated with appropriate
respect.'
It was strange, thought Floyd, how Chandra - much the smallest
person in the room - now seemed the largest. But the confrontation
had gone on far too long. At any moment Tanya would start to issue
direct orders, and the situation would become really nasty.
'Tanya, Vasili - can I have a word with you both? I think there is
a way of resolving the problem.'
Floyd's interruption was received with obvious relief, and two
minutes later he was relaxing with the Orlovs in their quarters.
(Or 'sixteenths', as Curnow had once christened them because of
their size. He had soon regretted the pun, because he had to
explain it to everyone except Sasha.)
'Thank you, Woody,' said Tanya, as she handed him a bulb of his
favourite Azerbaijan Shemakha. 'I was hoping you'd do that. I
suppose you have something - how do you put it? - up your
sleeve.'
'I believe so,' Floyd answered, squirting a few cubic centimetres
of the sweet wine into his mouth and savouring it gratefully. 'I'm
sorry if Chandra is being difficult.'
'So am I. What a good thing we have only one mad scientist
aboard.'
'That's not what you've sometimes told me,' grinned Academician
Vasili. 'Anyway, Woody - let's have it.'
'This is what I suggest. Let Chandra go ahead and do it his way.
Then there are just two possibilities.
'First, Hal will do exactly what we ask - control Discovery during
the two firing periods. Remember, the first isn't critical. If
something goes wrong while we're pulling away from Io, there's
plenty of time to make corrections. And that will give us a good
test of Hal's... willingness to cooperate.'
'But what about the Jupiter flyby? That's the one that really
counts. Not only do we burn most of Discovery's fuel there, but the
timing and thrust vectors have to be exactly right.'
'Could they be controlled manually?'
'I'd hate to try. The slightest error, and we'd either burn up, or
become a long-period comet. Due again in a couple of thousand
years.'
'But if there was no alternative?' Floyd insisted.
'Well, assuming we could take control in time, and had a good set
of alternative orbits precomputed - um, perhaps we might get away
with it.'
'Knowing you, Vasili, I'm sure that "might" means "would". Which
leads me to the second possibility I mentioned. If Hal shows the
slightest deviation from the program - we take over.'
'You mean - disconnect him?'
'Exactly.'
'That wasn't so easy last time.'
'We've learned a few lessons since then. Leave it to me. I can
guarantee to give you back manual control in about half a
second.'
'There's no danger, I suppose, that Hal will suspect anything?'
'Now you're getting paranoiac, Vasili. Hal's not that human. But
Chandra is - to give him the benefit of the doubt. So don't say a
word to him. We all agree with his plan completely, are sorry that
we ever raised any objections, and are perfectly confident that Hal
will see our point of view. Right, Tanya?'
'Right, Woody. And I congratulate you on your foresight; that
little gadget was a good idea.'
'What gadget?' asked Vasili.
'I'll explain one of these days. Sorry, Woody - that's all the
Shemakha you can have. I want to save it - until we're safely on
the way to Earth.'
No one would ever believe this without my photos, thought Max
Brailovsky as he orbited the two ships from half a kilometre away.
It seems comically indecent, as if Leonov is raping Discovery. And
now that he came to think of it, the rugged, compact Russian ship
did look positively male, when compared with the delicate, slender
American one. But most docking operations had distinctly sexual
overtones, and he remembered that one of the early cosmonauts - he
couldn't recall the name - had been reprimanded for his too vivid
choice of words at the - er, climax of his mission.
As far as he could tell from his careful survey, everything was in
order. The task of positioning the two ships and securing them
firmly together had taken longer than anticipated. It would never
have been possible at all without one of those strokes of luck that
sometimes - not always -favour those who deserve them. Leonov had
providentially carried several kilometres of carbon filament tape,
no bigger than the ribbon a girl might use to tie her hair, yet
capable of taking a strain of many tons. It had been thoughtfully
provided to secure instrument packages to Big Brother if all else
failed. Now it wrapped Leonov and Discovery in tender embrace -
sufficiently firmly, it was hoped, to prevent any rattlings and
shakings at all accelerations up to the one-tenth of a gravity that
was the maximum that full thrust could provide.
'Anything more you want me to check before I come home?' asked
Max.
'No,' replied Tanya. 'Everything looks fine. And we can't waste any
more time.'
That was true enough. If that mysterious warning was to be taken
seriously - and everyone now took it very seriously indeed - they
should start their escape manoeuvre within the next twenty-four
hours.
'Right - I'm bringing Nina back to the stable. Sorry about this,
old girl.'
'You never told us Nina was a horse.'
'I'm not admitting it now. And I feel bad about dumping her here in
space, just to give us a miserable few extra metres per
second.'
'We may be very glad of them in a few hours, Max. Anyway, there's
always a chance that someone may come and pick her up again, one
day.'
I very much doubt it, thought Max. And perhaps, after all, it was
appropriate to leave the little space pod there, as a permanent
reminder of Man's first visit to the kingdom of Jupiter.
With gentle, carefully timed pulses from the control jets he
brought Nina around the great sphere of Discovery's main
life-support module; his colleagues on the flight deck barely
glanced at him as he drifted past their curving window. The open
Pod Bay door yawned before him, and he jockeyed Nina delicately
down on to the extended docking arm.
'Pull me in,' he said, as soon as the latches had clicked shut. 'I
call that a well-planned EVA. There's a whole kilogram of
propellant left to take Nina out for the last time.'
Normally, there was little drama about a burn in deep space; it was
not like the fire and thunder - and always present risks - of a
lift-off from a planetary surface. If something went wrong, and the
motors failed to come up to full thrust - well, matters could
usually be corrected by a slightly longer burn. Or one could wait
until the appropriate point in orbit, and try again.
But this time, as the countdown proceeded toward zero, the tension
aboard both ships was almost palpable. Everyone knew that it was
the first real test of Hal's docility; only Floyd, Curnow, and the
Orlovs realized that there was a back-up system. And even they were
not absolutely sure that it would work.
'Good luck, Leonov,' said Mission Control, timing the message to
arrive five minutes before ignition. 'Hope everything's running
smoothly. And if it's not too much trouble, could you please get
some close-ups of the equator, longitude 115, as you go around
Jupiter. There's a curious dark spot there - presumably some kind
of upwelling, perfectly round, almost a thousand kilometres across.
Looks like the shadow of a satellite, but it can't be.'
Tanya made a brief acknowledgement that managed to convey, in a
remarkably few words, a profound lack of interest in the
meteorology of Jupiter at that moment. Mission Control sometimes
showed a perfect genius for tactlessness and poor timing.
'All systems functioning normally,' said Hal. 'Two minutes to
ignition.'
Strange, thought Floyd, how terminology often survives long after
the technology that gave it birth. Only chemical rockets were
capable of ignition; even if the hydrogen in a nuclear or plasma
drive did come into contact with oxygen, it would be far too hot to
burn. At such temperatures, all compounds were stripped back into
their elements.
His mind wandered, seeking other examples. People - particularly
older ones - still spoke of putting film into a camera, or gas into
a car. Even the phrase 'cutting a tape' was still sometimes heard
in recording studios - though that embraced two generations of
obsolete technologies.
'One minute to ignition.'
His mind flashed back to the here and now. This was the minute that
counted; for almost a hundred years, on launch pads and in control
centres, this was the longest sixty seconds that had ever existed.
Countless times it had ended in disaster; but only the triumphs
were remembered. Which will ours be?
The temptation to put his hand once more into the pocket that held
the activator for the cut-out switch was almost irresistible, even
though logic told him there was plenty of time for remedial action.
If Hal failed to obey his programming, that would be a nuisance -
not a disaster. The really critical time would be when they were
rounding Jupiter.
'Six... five... four... three... two... one. IGNITION!'
At first, the thrust was barely perceptible; it took almost a
minute to build up to the full tenth of a gee. Nevertheless,
everyone started clapping immediately, until Tanya signalled for
silence. There were many checks to be made; even if Hal was doing
his best - as he certainly seemed to be - there was so much that
could still go wrong.
Discovery's antenna mount - which was now taking most of the strain
from Leonov's inertia - had never been intended for such
mistreatment. The ship's chief designer, called out of retirement,
had sworn that the safety margin was adequate. But he might be
wrong, and materials had been known to become brittle after years
in space.
And the tapes holding the two ships together might not have been
located accurately; they might stretch or slip. Discovery might not
be able to correct for the off-centre of mass, now that it was
carrying a thousand tons piggyback. Floyd could imagine a dozen
things that could go wrong; it was little consolation to remember
that it was always the thirteenth that actually happened.
But the minutes dragged on uneventfully; the only proof that
Discovery's engines were operating was the fractional,
thrust-induced gravity and a very slight vibration transmitted
through the walls of the ships. Io and Jupiter still hung where
they had been for weeks, on opposite sides of the sky.
'Cut-off in ten seconds. Nine... eight... seven... six... five...
four... three,.. two... NOW!'
'Thank you, Hal, On the button.'
Now that was another phrase that was badly dated; for at least a
generation, touch pads had almost entirely replaced buttons. But
not for all applications; in critical cases, it was best to have a
device that moved perceptibly with a nice, satisfying click.
'I confirm that,' said Vasili. 'No need for any corrections until
mid-course.'
'Say goodbye to glamorous, exotic Io - real estate agent's dream
world,' said Curnow. 'We'll all be happy to miss you.'
That sounds more like the old Walter, Floyd told himself. For the
last few weeks, he had been oddly subdued, as if he had something
on his mind. (But who did not?) He seemed to spend a good deal of
his scanty free time in quiet discussions with Katerina: Floyd
hoped that he had not developed some medical problem. They had been
very lucky so far on that score; the last thing they needed at this
stage was an emergency that required the Surgeon-Commander's
expertise.
'You're being unkind, Walter,' said Brailovsky. 'I was beginning to
like the place. It might be fun to go boating on those lava
lakes.'
'What about a volcano barbecue?'
'Or genuine molten sulphur baths?'
Everyone was lighthearted, even a little hysterical with relief.
Though it was far too early to relax and the most critical phase of
the escape manoeuvre still lay ahead, the first step had been
safely taken on the long journey home. That was cause enough for a
little modest rejoicing.
It did not last long, for Tanya quickly ordered all those not on
essential duty to get some rest - if possible, some sleep - in
preparation for the Jupiter swing-by only nine hours ahead. When
those addressed were slow to move, Sasha cleared the decks by
shouting, 'You'll hang for this, you mutinous dogs!' Only two
nights before, as a rare relaxation, they had all enjoyed the
fourth version of Mutiny on the Bounty, generally agreed by movie
historians to have the best Captain Bligh since the fabled Charles
Laughton. There was some feeling on board that Tanya should not
have seen it, lest it give her ideas.
After a couple of restless hours in his cocoon, Floyd abandoned the
quest for sleep and wandered up to the observation deck. Jupiter
was much larger and slowly waning as the ships hurtled toward their
closest approach over the nightside. A glorious, gibbous disk, it
showed such an infinite wealth of detail - cloud belts, spots of
every colour from dazzling white to brick red, dark upwellings from
the unknown depths, the cyclonic oval of the Great Red Spot -that
the eye could not possibly absorb it all. The round, dark shadow of
one moon - probably Europa, Floyd guessed - was in transit. He was
seeing this incredible sight for the last time; even though he had
to be at maximum efficiency in six hours, it was a crime to waste
precious moments in sleep.
Where was that spot that Mission Control had asked them to observe?
It should have been coming into view, but Floyd was not sure if it
would be visible to the naked eye. Vasili would be too busy to
bother about it; perhaps he could help by doing a little amateur
astronomy. There had, after all, been a brief time, only thirty
years ago, when he had earned his living as a professional.
He activated the controls of the main fifty-centimetre telescope -
fortunately, the field of view was not blocked by the adjacent bulk
of Discovery - and scanned along the equator at medium power. And
there it was, just coming over the edge of the disk.
By force of circumstance, Floyd was now one of the Solar System's
ten greatest experts on Jupiter; the other nine were working or
sleeping around him. He saw at once that there was something very
odd about this spot; it was so black that it looked like a hole
punched through the clouds. From his point of view it appeared to
be a sharp-edged ellipse; Floyd guessed that from directly above,
it would be a perfect circle.
He recorded a few images, then increased the power to maximum.
Already Jupiter's rapid spin had brought the formation into clearer
view; and the more he stared, the more puzzled Floyd became.
'Vasili,' he called over the intercom, 'if you can spare a minute -
have a look at the fifty-centimetre monitor.'
'What are you observing? Is it important? I'm checking the
orbit.'
'Take your time, of course. But I've found that spot Mission
Control reported. It looks very peculiar.'
'Hell! I'd forgotten all about it. We're a fine lot of observers if
those guys back on Earth have to tell us where to look. Give me
another five minutes - it won't run away.'
True enough, thought Floyd; in fact it will get clearer. And there
was no disgrace in missing something that terrestrial - or lunar -
astronomers had observed. Jupiter was very big, they had been very
busy, and the telescopes on the Moon and in Earth orbit were a
hundred times more powerful than the instrument he was using
now.
But it was getting more and more peculiar. For the first time,
Floyd began to feel a distinct sense of unease. Until that moment,
it had never occurred to him that the spot could be anything but a
natural formation - some trick of Jupiter's incredibly complex
meteorology. Now he began to wonder.
It was so black, like night itself. And so symmetrical; as it came
into clearer view it was obviously a perfect circle. Yet it was not
sharply defined; the edge had an odd fuzziness, as if it was a
little out of focus.
Was it imagination, or had it grown, even while he was watching? He
made a quick estimate, and decided that the thing was now two
thousand kilometres across. It was only a little smaller than the
still-visible shadow of Europa, but was so much darker that there
was no risk of confusion.
'Let's have a look,' said Vasili, in a rather condescending tone.
'What do you think you've found? Oh...' His voice trailed away into
silence.
This is it, thought Floyd, with a sudden icy conviction. Whatever
it may be.
Yet on further reflection, after the initial amazement had worn
off, it was hard to see how a spreading black stain on the face of
Jupiter could represent any kind of danger. It was extraordinary -
inexplicable - but not as important as the critical events now only
seven hours in the future. A successful burn at perijove was all
that mattered; they would have plenty of time to study mysterious
black spots on the way home.
And to sleep; Floyd had given up all attempts at that.
Though the feeling of danger - at least, of known danger - was much
less than on their first approach to Jupiter, a mixture of
excitement and apprehension kept him wide awake. The excitement was
natural and understandable; the apprehension had more complex
causes. Floyd made it a rule never to worry about events over which
he could have absolutely no control; any external threat would
reveal itself in due time and be dealt with then. But he could not
help wondering if they had done everything possible to safeguard
the ships.
Apart from onboard mechanical failures, there were two main sources
of concern. Although the tapes that secured Leonov and Discovery
together had shown no tendency to slip, their severest test was
still to come. Almost equally critical would be the moment of
separation when the smallest of the explosive charges once intended
to jolt Big Brother would be used at uncomfortably close quarters.
And, of course, there was Hal.
He had carried out the deorbiting manoeuvre with exquisite
precision. He had run the simulations of the Jupiter flyby, right
down to Discovery's last drop of fuel, without any comments or
objections. And although Chandra, as agreed, had carefully
explained what they were trying to do, did Hal really understand
what was happening?
Floyd had one overriding concern, which in the preceding few days
had become almost an obsession. He could picture everything going
perfectly, the ships halfway through the final manoeuvre, the
enormous disk of Jupiter filling the sky only a few hundred
kilometres below them - and then Hal electronically clearing his
throat and saying:
'Dr Chandra, do you mind if I ask you a question?' It did not
happen exactly that way.
The Great Black Spot, as it had been inevitably christened, was now
being carried out of sight by Jupiter's swift rotation. In a few
hours the still-accelerating ships would catch up with it over the
nightside of the planet, but this was the last chance for a close
daylight observation.
It was still growing at an extraordinary speed; in the last two
hours, it had more than doubled its area. Except for the fact that
it retained its blackness as it expanded, it resembled an ink-stain
spreading in water. Its boundary - now moving at near-sonic speed
in the Jovian atmosphere - still looked curiously fuzzy and out of
focus; at the very highest power of the ship's telescope, the
reason for this was at last apparent.
Unlike the Great Red Spot, the Great Black Spot was not a
continuous structure; it was built up from myriads of tiny dots,
like a half-tone print viewed through a magnifying glass. Over most
of its area, the dots were so closely spaced that they were almost
touching, but at the rim they became more and more widely spaced,
so that the Spot ended in a grey penumbra rather than at a sharp
frontier.
There must have been almost a million of the mysterious dots, and
they were distinctly elongated - ellipses rather than circles.
Katerina, the least imaginative person aboard, surprised everybody
by saying that it looked as if someone had taken a sackful of rice,
dyed it black, and poured it on the face of Jupiter.
And now the Sun was dropping down behind the huge, swiftly
narrowing arch of the dayside, as for the second time Leonov raced
into the Jovian night for an appointment with destiny. In less than
thirty minutes the final burn would commence, and things would
start to happen very quickly indeed.
Floyd wondered if he should have joined Chandra and Curnow,
standing watch on Discovery. But there was nothing he could do; in
an emergency, he would only be in the way. The cut-off switch was
in Curnow's pocket, and Floyd knew that the younger man's reactions
were a good deal swifter than his own. If Hal showed the slightest
sign of misbehaviour, he could be disconnected in less than a
second, but Floyd felt certain that such extreme measures would not
be necessary. Since he had been allowed to do things his own way,
Chandra had cooperated completely in setting up the procedures for
a manual takeover, should that unfortunate necessity arise. Floyd
was confident that he could be trusted to carry out his duty -
however much he might regret the need.
Curnow was not quite so sure. He would be happier, he had told
Floyd, if he had multiple redundancy in the form of a second
cut-off switch - for Chandra. Meanwhile there was nothing that
anyone could do but wait and watch the approaching cloudscape of
the nightside, dimly visible by the reflected light of passing
satellites, the glow of photo-chemical reactions, and frequent
titanic lightning flashes from thunderstorms larger than Earth.
The sun winked out behind them, eclipsed in seconds by the immense
globe they were so swiftly approaching. When they saw it again,
they should be on their way home.
'Twenty minutes to ignition. All systems nominal.'
'Thank you, Hal.'
I wonder if Chandra was being quite truthful, thought Curnow, when
he said that Hal would be confused if anyone else spoke to him.
I've talked to him often enough, when nobody was around, and he
always understood me perfectly. Still, there's not much time left
for friendly conversation now, though it would help to reduce the
strain.
What's Hal really thinking - if he thinks - about the mission? All
his life, Curnow had shied away from abstract, philosophical
questions: I'm a nuts-and-bolts man, he had often claimed, though
there were not too many of either in a spaceship. Once, he would
have laughed at the idea, but now he began to wonder: Did Hal sense
that he would soon be abandoned, and if so, would he resent it?
Curnow almost reached for the cut-off switch in his pocket, but
checked himself. He had already done this so often that Chandra
might be getting suspicious.
For the hundredth time, he rehearsed the sequence of events that
were due to take place during the next hour. The moment that
Discovery's fuel was exhausted, they would close down all but
essential systems, and dash back to Leonov through the connecting
tube. That would be decoupled, the explosive charges would be
fired, the ships would drift apart - and Leonov's own engines would
start to fire. The separation should take place, if everything went
according to plan, just when they were making their closest
approach to Jupiter; that would take maximum advantage of the
planet's gravitational largesse.
'Fifteen minutes to ignition. All systems nominal.'
'Thank you, Hal.'
'By the way,' said Vasili, from the other ship, 'we're catching up
with the Great Black Spot again. Wonder if we can see anything
new.'
I rather hope not, thought Curnow; we've got quite enough on our
hands at the moment. Nevertheless, he gave a quick glance at the
image Vasili was transmitting on the telescope monitor.
At first he could see nothing except the faintly glimmering
nightside of the planet; then he saw, on the horizon, a
foreshortened circle of deeper darkness. They were rushing toward
it with incredible speed.
Vasili increased the light amplification, and the entire image
brightened magically. At last, the Great Black Spot resolved itself
into its myriad identical elements.
My God, thought Curnow, I just don't believe it!
He heard exclamations of surprise from Leonov: all the others had
shared in the same revelation at the same moment.
'Dr Chandra,' said Hal, 'I detect strong vocal stress patterns. Is
there a problem?'
'No, Hal,' Chandra answered quickly. 'The mission is proceeding
normally. We've just had rather a surprise - that's all. What do
you make of the image on monitor circuit 16?'
'I see the nightside of Jupiter. There is a circular area, 3,250
kilometres in diameter, which is almost compietely covered with
rectangular objects.'
'How many?'
There was the briefest of pauses, before Hal flashed the number on
the video display:
1,355,000 ± 1,000
'And do you recognize them?'
'Yes. They are identical in size and shape to the object you refer
to as Big Brother. Ten minutes to ignition. All systems
nominal.'
Mine aren't, thought Curnow. So the damn thing's gone down to
Jupiter - and multiplied. There was something simultaneously comic
and sinister about a plague of black monoliths; and to his puzzled
surprise, that incredible image on the monitor screen had a certain
weird familiarity.
Of course - that was it! Those myriad, identical black rectangles
reminded him of - dominoes. Years ago, he had seen a video
documentary showing how a team of slightly crazy Japanese had
patiently stood a million dominoes on end, so that when the very
first one was toppled, all the others would inevitably follow. They
had been arranged in complex patterns, some underwater, some up and
down little stairways, others along multiple tracks so that they
formed pictures and patterns as they fell. It had taken weeks to
set them up; Curnow remembered now that earthquakes had several
times foiled the enterprise, and the final toppling, from first
domino to the last, had taken more than an hour.
'Eight minutes to ignition. All systems nominal. Dr Chandra - may I
make a suggestion?'
'What is it, Hal?'
'This is a very unusual phenomenon. Do you not think I should abort
the countdown, so that you can remain to study it?'
Aboard Leonov, Floyd started to move quickly toward the bridge.
Tanya and Vasili might be needing him. Not to mention Chandra and
Curnow - what a situation! And suppose Chandra took Hal's side? If
he did - they might both be right! After all, was this not the very
reason they had come here?
If they stopped the countdown, the ships would loop around Jupiter
and be back at precisely the same spot in nineteen hours. A
nineteen-hour hold would create no problems; if it was not for that
enigmatic warning, he would have strongly recommended it
himself.
But they had very much more than a warning. Below them was a
planetary plague spreading across the face of Jupiter. Perhaps they
were indeed running away from the most extraordinary phenomenon in
the history of science. Even so, he preferred to study it from a
safer distance.
'Six minutes to ignition,' said Hal. 'All systems nominal. I am
ready to stop the countdown if you agree. Let me remind you that my
prime directive is to study everything in Jupiter space that may be
connected with intelligence.'
Floyd recognized that phrase all too well: he had written it
himself. He wished he could delete it from Hal's memory.
A moment later, he had reached the bridge and joined the Orlovs.
They both looked at him with alarmed concern.
'What do you recommend?' asked Tanya swiftly.
'It's up to Chandra, I'm afraid. Can I speak to him - on the
private line?'
Vasili handed over the microphone.
'Chandra? I assume that Hal can't hear this?'
'Correct, Dr Floyd.'
'You've got to talk quickly. Persuade him that the countdown must
continue, that we appreciate his - er, scientific enthusiasm - ah,
that's the right angle - say we're confident that he can do the job
without our help. And we'll be in touch with him all the time, of
course.'
'Five minutes to ignition. All systems nominal. I am still waiting
for your answer, Dr Chandra.'
So are we all, thought Curnow, only a metre away from the
scientist. And if I do have to push that button at last, it will be
something of a relief. In fact, I'll rather enjoy it.
'Very well, Hal. Continue the countdown. I have every confidence in
your ability to study all phenomena in Jupiter space, without our
supervision. Of course, we will be in touch with you at all
times.'
'Four minutes to ignition. All systems nominal. Propellant-tank
pressurization completed. Voltage steady on plasma trigger. Are you
sure you are making the right decision, Dr Chandra? I enjoy working
with human beings and have a stimulating relationship with them.
Ship's attitude correct to point one milliradian.'
'We enjoy working with you, Hal. And we will still be doing so,
even if we are millions of kilometres away.'
'Three minutes to ignition. All systems nominal, Radiation
shielding checked. There is a problem of the time lag, Dr Chandra.
It may be necessary to consult each other without any delay.'
This is insane, Curnow thought, his hand now never far from the
cut-off switch. I really believe that Hal is - lonely. Is he
mimicking some part of Chandra's personality that we never
suspected?
The lights flickered, so imperceptibly that only someone familiar
with every nuance of Discovery's behaviour would have noticed. It
could be good news or bad - the plasma firing sequence starting, or
being terminated...
He risked a quick glance at Chandra; the little scientist's face
was drawn and haggard, and for almost the first time Curnow felt
real sympathy for him as another human being. And he remembered the
startling information that Floyd had confided in him - Chandra's
offer to stay with the ship, and keep Hal company on the three-year
voyage home. He had heard no more of the idea, and presumably it
had been quietly forgotten after the warning. But perhaps Chandra
was being tempted again; if he was, there was nothing that he could
do about it at that stage. There would be no time to make the
necessary preparations, even if they stayed on for another orbit
and delayed their departure beyond the deadline. Which Tanya would
certainly not permit after all that had now happened.
'Hal,' whispered Chandra, so quietly that Curnow could scarcely
hear him. 'We have to leave. I don't have time to give you all the
reasons, but I can assure you it's true.'
'Two minutes to ignition. All systems nominal. Final sequence
started. I am sorry that you are unable to stay. Can you give me
some of the reasons, in order of importance?'
'Not in two minutes, Hal. Proceed with the countdown. I will
explain everything later. We still have more than an hour
together.'
Hal did not answer. The silence stretched on and on. Surely the
one-minute announcement was overdue ...
Curnow glanced at the clock. My God, he thought, Hal's missed it!
Has he stopped the countdown?
Curnow's hand fumbled uncertainly for the switch. What do I do now?
I wish Floyd would say something, dammit, but he's probably afraid
of making things worse...
I'll wait until time zero - no, it's not that critical, let's say
an extra minute - then I'll zap him and we'll go over to
manual...
From far, far away there came a faint, whistling scream, like the
sound of a tornado marching just below the edge of the horizon.
Discovery started to vibrate; there was the first intimation of
returning gravity.
'Ignition,' said Hal. 'Full thrust at T plus fifteen seconds.'
'Thank ,you, Hal,' replied Chandra.
To Heywood Floyd, aboard the suddenly unfamiliar - because no
longer weightless - environment of Leonov's flight deck, the
sequence of events had seemed more like a classic slow-motion
nightmare than reality. Only once before in his life had he known a
similar situation, when he had been in the back of a car during an
uncontrollable skid. There had been that same sense of utter
helplessness - coupled with the thought: This doesn't really matter
- it's not actually happening to me.
Now that the firing sequence had started, his mood changed;
everything seemed real again. It was working out exactly as they
had planned; Hal was guiding them safely back to Earth. With every
minute that passed, their future was becoming more secure; Floyd
began slowly to relax, even though he remained alert to all that
was happening around him.
For the very last time - and when would any man come here again? -
he was flying over the nightside of the greatest of planets,
encompassing the volume of a thousand Earths. The ships had been
rolled so that Leonov was between Discovery and Jupiter, and their
view of the mysteriously glimmering cloudscape was not blocked.
Even now, dozens of instruments were busily probing and recording;
Hal would continue the work when they were gone.
Since the immediate crisis was over, Floyd moved cautiously 'down'
from the flight deck-how strange to feel weight again, even if it
was only ten kilos! - and joined Zenia and Katerina in the
observation lounge. Apart from the very faintest of red emergency
lights, it had been completely blacked out so that they could
admire the view with unimpaired night vision. He felt sorry for Max
Brailovsky and Sasha Kovalev, who were sitting in the airlock,
fully suited up, missing the marvellous spectacle. They had to be
ready to leave at a moment's notice to cut the straps securing the
ships together - if any of the explosive charges failed to
operate.
Jupiter filled the entire sky; it was a mere five hundred
kilometres away, so they could see only a tiny fraction of its
surface - no more than one could see of Earth from an altitude of
fifty kilometres. As his eyes grew accustomed to the dim light,
most of it reflected from the icy crust of distant Europa, Floyd
could make out a surprising amount of detail. There was no colour
at the low level of illumination - except for a hint of red here
and there - but the banded structure of the clouds was very
distinct, and he could see the edge of a small cyclonic storm
looking like an oval island covered with snow. The Great Black Spot
had long since fallen astern, and they would not see it again until
they were well on the way home.
Down there beneath the clouds, occasional explosions of light
flared, many of them obviously caused by the Jovian equivalent of
thunderstorms. But other glows and outbursts of luminescence were
more long-lived, and of more uncertain origin. Sometimes rings of
light would spread out like shock waves from a central source; and
occasional rotating beams and fans occurred. It required little
imagination to pretend that they were proof of a technological
civilization down beneath those clouds - the lights of cities, the
beacons of airports. But radar and balloon probes had long ago
proved that nothing solid was down there for thousands upon
thousands of kilometres, all the way to the unattainable core of
the planet.
Midnight on Jupiter! The last close-up glimpse was a magical
interlude he would remember all his life. He could enjoy it all the
more because, surely, nothing could now go wrong; and even if it
did, he would have no reason to reproach himself He had done
everything possible to ensure success.
It was very quiet in the lounge; no one wished to speak as the
carpet of clouds unrolled swiftly beneath them. Every few minutes
Tanya or Vasili announced the status of the burn; toward the end of
Discovery's firing time, tension began to increase again. This was
the critical moment - and no one knew exactly when it would be.
There was some doubt as to the accuracy of the fuel gauges, and the
burn would continue until they were completely dry.
'Estimated cut-off in ten seconds,' said Tanya. 'Walter, Chandra -
get ready to come back. Max, Vasili - stand by in case you're
needed. Five... four... three... two... one... zero!'
There was no change; the faint scream of Discovery's engines still
reached them through the thickness of the two hulls, and the
thrust-induced weight still continued to grip their limbs. We're in
luck, thought Floyd; the gauges must have been reading low, after
all. Every second of extra firing was a bonus; it might even mean
the difference between life and death. And how strange to hear a
countup instead of a countdown!
five seconds... ten seconds... thirteen seconds. That's it - lucky
thirteen!'
Weightlessness, and silence, returned. On both ships, there was a
brief burst of cheering. It was quickly truncated, for much was
still to be done - and it had to be done swiftly.
Floyd was tempted to go to the airlock so that he could give his
congratulations to Chandra and Curnow as soon as they came aboard.
But he would only be in the way; the airlock would be a very busy
place as Max and Sasha prepared for their possible EVA and the
tubeway joining the two ships was disconnected. He would wait in
the lounge, to greet the returning heroes.
And he could now relax even further - perhaps from eight to seven,
on a scale of ten. For the first time in weeks, he could forget
about the radio cut-off. It would never be needed; Hal had
performed impeccably. Even if he wished, he could do nothing to
affect the mission since Discovery's last drop of propellant had
been exhausted.
'All aboard,' announced Sasha. 'Hatches sealed. I'm going to fire
the charges.'
There was not the faintest sound as the explosives were detonated,
which surprised Floyd; he had expected some noise to be transmitted
through the straps, taut as steel bands, that linked the ships
together. But there was no doubt that they had gone off as planned,
for Leonov gave a series of tiny shudders, as if someone was
tapping on the hull. A minute later, Vasili triggered the attitude
jets for a single brief burst.
'We're free!' he shouted. 'Sasha, Max - you won't be needed!
Everyone get to your hammocks - ignition in one hundred
seconds!'
And now Jupiter was rolling away, and a strange new shape appeared
outside the window - the long, skeletal frame of Discovery,
navigation lights still shining as it drifted away from them and
into history. No time remained for sentimental farewells; in less
than a minute Leonov's drive would start to operate.
Floyd had never heard it under full power and wanted to protect his
ears from the roaring scream that now filled the universe. Leonov's
designers had not wasted payload on sound-insulation that would be
needed for only a few hours of a voyage that would last for years.
And his weight seemed enormous - yet it was barely a quarter of
that which he had known all his life.
Within minutes, Discovery had vanished astern, though the flash of
its warning beacon could be seen until it had dropped below the
horizon. Once again, Floyd told himself, I'm rounding Jupiter -
this time gaining speed, not losing it. He glanced across at Zenia,
just visible in the darkness with her nose pressed to the
observation window. Was she also recalling that last occasion, when
they shared the hammock together? There was no danger of
incineration now; at least she would not be terrified of that
particular fate. Anyway, she seemed a much more confident and
cheerful person, undoubtedly thanks to Max - and perhaps Walter as
well.
She must have become aware of his scrutiny, for she turned and
smiled, then gestured toward the unwinding cloudscape below.
'Look!' she shouted in his ear, 'Jupiter has a new moon!'
What is she trying to say? Floyd asked himself. Her English still
isn't very good, but she couldn't possibly have made a mistake in a
simple sentence like that. I'm sure I heard her correctly - yet
she's pointing downward, not upward.
And then he realized that the scene immediately below them had
become much brighter; he could even see yellows and greens that had
been quite invisible before. Something far more brilliant than
Europa was shining on the Jovian clouds.
Leonov itself, many times brighter than Jupiter's noonday sun, had
brought a false dawn to the world it was leaving forever. A
hundred-kilometre-long plume of incandescent plasma was trailing
behind the ship, as the exhaust from the Sakharov Drive dissipated
its remaining energies in the vacuum of space.
Vasili was making an announcement, but the words were completely
unintelligible. Floyd glanced at his watch; yes, that would be
right about now. They had achieved Jupiter escape velocity. The
giant could never recapture them.
And then, thousands of kilometres ahead, a great bow of brilliant
light appeared in the sky - the first glimpse of the real Jovian
dawn, as full of promise as any rainbow on Earth. Seconds later the
Sun leaped up to greet them - the glorious Sun, that would now grow
brighter and closer every day.
A few more minutes of steady acceleration, and Leonov would be
launched irrevocably on the long voyage home. Floyd felt an
overwhelming sense of relief and relaxation. The immutable laws of
celestial mechanics would guide him through the inner Solar System,
past the tangled orbits of the asteroids, past Mars - nothing could
stop him from reaching Earth.
In the euphoria of the moment, he had forgotten all about the
mysterious black stain, expanding across the face of Jupiter.
+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
They saw it again the next morning, ship's time, as it came around
to the dayside of Jupiter. The area of darkness had now spread
until it covered an appreciable fraction of the planet, and at last
they were able to study it at leisure, and in detail.
'Do you know what it reminds me of?' said Katerina. 'A virus
attacking a cell. The way a phage injects its DNA into a bacterium,
and then multiplies until it takes over.'
'Are you suggesting,' asked Tanya incredulously, 'that Zagadka is
eating Jupiter?'
'It certainly looks like it.'
'No wonder Jupiter is beginning to look sick. But hydrogen and
helium won't make a very nourishing diet, and there's not much else
in that atmosphere. Only a few percent of other elements.'
'Which adds up to some quintillions of tons of sulphur and carbon
and phosphorus and everything else at the lower end of the periodic
table,' Sasha pointed out. 'In any case, we're talking about a
technology that can probably do anything that doesn't defy the laws
of physics. If you have hydrogen, what more do you need? With the
right know-how, you can synthesize all the other elements from
it.'
'They're sweeping up Jupiter - that's for sure,' said Vasili. 'Look
at this.'
An extreme close-up of one of the myriad identical rectangles was
now displayed on the telescope monitor. Even to the naked eye, it
was obvious that streams of gas were flowing into the two smaller
faces; the patterns of turbulence looked very much like the lines
of force revealed by iron filings, clustered around the ends of a
bar magnet.
'A million vacuum cleaners,' said Curnow, 'sucking up Jupiter's
atmosphere. But why? And what are they doing with it?'
'And how do they reproduce?' asked Max. 'Have you caught any of
them in the act?'
'Yes and no,' answered Vasili. 'We're too far away to see details,
but it's a kind of fission - like an amoeba.'
'You mean - they split in two, and the halves grow back to the
original size?'
'Nyet. There aren't any little Zagadki - they seem to grow until
they've doubled in thickness, then split down the middle to produce
identical twins, exactly the same size as the original. And the
cycle repeats itself in approximately two hours.'
'Two hours!' exclaimed Floyd. 'No wonder that they've spread over
half the planet. It's a textbook case of exponential growth.'
'I know what they are!' said Ternovsky in sudden excitement.
'They're von Neumann machines!'
'I believe you're right,' said Vasili. 'But that still doesn't
explain what they're doing. Giving them a label isn't all that much
help.'
'And what,' asked Katerina plaintively, 'is a von Neumann machine?
Explain, please.'
Orlov and Floyd started speaking simultaneously. They stopped in
some confusion, then Vasili laughed and waved to the American.
'Suppose you had a very big engineering job to do, Katerina - and I
mean big, like strip-mining the entire face of the Moon. You could
build millions of machines to do it, but that might take centuries.
If you were clever enough, you'd make just one machine - but with
the ability to reproduce itself from the raw materials around it.
So you'd start a chain reaction, and in a very short time, you'd
have bred enough machines to do the job in decades, instead of
millennia. With a sufficiently high rate of reproduction, you could
do virtually anything in as short a period of time as you wished.
The Space Agency's been toying with the idea for years - and I know
you have as well, Tanya.'
'Yes: exponentiating machines. One idea that even Tsiolkovski
didn't think of.'
'I wouldn't care to bet on that,' said Vasili. 'So it looks,
Katerina, as if your analogy was pretty close. A bacteriophage is a
von Neumann machine.'
'Aren't we all?' asked Sasha. 'I'm sure Chandra would say so.'
Chandra nodded his agreement.
'That's obvious. In fact, von Neumann got the original idea from
studying living systems.'
'And these living machines are eating Jupiter!'
'It certainly looks like it,' said Vasili. 'I've been doing some
calculations, and I can't quite believe the answers - even though
it's simple arithmetic.'
'It may be simple to you,' said Katerina. 'Try to let us have it
without tensors and differential equations.'
'No - I mean simple,' insisted Vasili. 'In fact, it's a perfect
example of the old population explosion you doctors were always
screaming about in the last century. Zagadka reproduces every two
hours. So in only twenty hours there will be ten doublings. One
Zagadka will have become a thousand.'
'One thousand and twenty-four,' said Chandra.
'I know, but let's keep it simple. After forty hours there will be
a million - after eighty, a million million. That's about where we
are now, and obviously, the increase can't continue indefinitely.
In a couple more days, at this rate, they'll weigh more than
Jupiter!'
'So they'll soon begin to starve,' said Zenia. 'And what will
happen then?'
'Saturn had better look out,' answered Brailovsky. 'Then Uranus and
Neptune. Let's hope they don't notice little Earth.'
'What a hope! Zagadka's been spying on us for three million
years!'
Walter Curnow suddenly started to laugh.
'What's so funny?' demanded Tanya.
'We're talking about these things as if they're persons -
intelligent entities. They're not - they're tools. But
general-purpose tools - able to do anything they have to. The one
on the Moon was a signalling device - or a spy, if you like. The
one that Bowman met - our original Zagadka - was some kind of
transportation system. Now it's doing something else, though God
knows what. And there may be others all over the Universe,
'I had just such a gadget when I was a kid... Do you know what
Zagadka really is? Just the cosmic equivalent of the good old Swiss
Army knife!'
It was not easy to compose the message, especially after the one he
had just sent to his lawyer. Floyd felt like a hypocrite; but he
knew it had to be done to minimize the pain that was inevitable on
both sides.
He was sad, but no longer disconsolate. Because he was coming back
to Earth in an aura of successful achievement - even if not
precisely heroism - he would be bargaining from a position of
strength. No one - no one - would be able to take Chris away from
him.
'My dear Caroline [it was no longer 'My dearest'], I am on my way
home. By the time you get this, I'll already be in hibernation.
Only a few hours from now, as it will seem to me, I'll open my eyes
- and there will be the beautiful blue Earth hanging in space
beside me.
'Yes, I know it will still be many months for you, and I'm sorry.
But we knew that's the way it would be before I left; as it is, I'm
getting back weeks ahead of schedule because of the change in the
mission plan.
'I hope we can work something out. The main question is: What's
best for Chris? Whatever our own feelings, we must put him first. I
know I'm willing to do so, and I'm sure you are.'
Floyd switched off the recorder. Should he say what he had
intended: 'A boy needs his father?' No - it would not be tactful,
and might only make matters worse. Caroline might well retort that
between birth and four years old it was the mother who mattered
most to a child - and if he had believed otherwise, he should have
stayed on Earth.
'... Now about the house. I'm glad the Regents have taken that
attitude, which will make it much easier for both of us. I know we
both loved the place, but it will be too big now and will bring
back too many memories. For the time being, I'll probably get an
apartment in Hilo: I hope I can find some permanent place as
quickly as possible.
'That's one thing I can promise everyone - I won't leave Earth
again. I've had enough of space travelling for one lifetime. Oh,
perhaps the Moon, if I really have to - but of course that's just a
weekend excursion.
'And talking of moons, we've just passed the orbit of Sinope, so
we're now leaving the Jovian system. Jupiter is more than twenty
million kilometres away, and is barely larger than our own
Moon.
'Yet even from this distance, you can tell that something terrible
has happened to the planet. Its beautiful orange colour has
vanished; it's a kind of sickly grey, only a fraction of its former
brilliance. No wonder it's only a faint star now in the sky of
Earth.
'But nothing else has happened, and we're well past the deadline.
Could the whole thing have been a false alarm or a kind of cosmic
practical joke? I doubt if we'll ever know. Anyway, it's brought us
home ahead of schedule, and I'm grateful for that.
'Goodbye for the present, Caroline - and thank you for everything.
I hope we can still be friends. And my dearest love, as ever, to
Chris.'
When he had finished, Floyd sat quietly for a while in the tiny
cubicle he would not need much longer. He was just about to carry
the audio chip up to the bridge for transmission, when Chandra came
drifting in.
Floyd had been agreeably surprised by the way in which the
scientist had accepted his increasing separation from Hal. They
were still in touch for several hours every day, exchanging data on
Jupiter and monitoring conditions aboard Discovery. Though no one
had expected any great display of emotion, Chandra seemed to be
taking his loss with remarkable fortitude. Nikolai Ternovsky, his
only confidant, had been able to give Floyd a plausible explanation
of his behaviour.
'Chandra's got a new interest, Woody. Remember - he's in a business
where if something works, it's obsolete. He's learned a lot in the
last few months. Can't you guess what he's doing now?'
'Frankly, no. You tell me.'
'He's busy designing HAL 10,000.'
Floyd's jaw dropped. 'So that explains those log messages to Urbana
that Sasha's been grumbling about. Well, he won't be blocking the
circuits much longer.'
Floyd recalled the conversation when Chandra entered; he knew
better than to ask the scientist if it was true, for it was really
none of his business. Yet there was another matter about which he
was still curious.
'Chandra,' he said, 'I don't believe I ever thanked you properly
for the job you did at the flyby, when you persuaded Hal to
cooperate. For a while, I was really afraid he'd give us trouble.
But you were confident all along - and you were right. Still,
didn't you have any qualms?'
'Not at all, Dr Floyd.'
'Why not? He must have felt threatened by the situation - and you
know what happened last time.'
'There was a big difference. If I may say so, perhaps the
successful outcome this time had something to do with our national
characteristics.'
'I don't understand.'
'Put it this way, Dr Floyd. Bowman tried to use force against Hal.
I didn't. In my language we have a word - ahimsa. It's usually
translated as "non-violence", though it has more positive
implications. I was careful to use ahimsa in my dealings with
Hal.'
'Very commendable, I'm sure. But there are times when something
more energetic is needed, regrettable though the necessity may be.'
Floyd paused, wrestling with temptation. Chandra's holier-than-thou
attitude was a little tiresome. It wouldn't do any harm, now, to
tell him some of the facts of life.
'I'm glad it's worked out this way. But it might not have done so,
and I had to prepare for every eventuality. Ahimsa, or whatever you
call it, is all very well; I don't mind admitting I had a back-up
to your philosophy. If Hal had been - well, stubborn, I could have
dealt with him.'
Floyd had once seen Chandra crying; now he saw him laughing, and
that was an equally disconcerting phenomenon.
'Really, Dr Floyd! I'm sorry you give me such low marks for
intelligence. It was obvious from the beginning that you'd install
a power cut-out somewhere. I disconnected it months ago.'
Whether the flabbergasted Floyd could think of a suitable answer
would never be known. He was still giving a very creditable
imitation of a galled fish when up on the flight deck Sasha cried
out: 'Captain! All hands! Get to the monitors! BOZHE MOI! LOOK AT
THAT!'
Now the long wait was ending. On yet another world, intelligence
had been born and was escaping from its planetary cradle. An
ancient experiment was about to reach its climax.
Those who had begun that experiment, so long ago, had not been men
- or even remotely human. But they were flesh and blood, and when
they looked out across the deeps of space, they had felt awe, and
wonder, and loneliness. As soon as they possessed the power, they
set forth for the stars. In their explorations, they encountered
life in many forms and watched the workings of evolution on a
thousand worlds. They saw how often the first faint sparks of
intelligence flickered and died in the cosmic night.
And because, in all the Galaxy, they had found nothing more
precious than Mind, they encouraged its dawning everywhere. They
became farmers in the fields of stars; they sowed, and sometimes
they reaped.
And sometimes, dispassionately, they had to weed.
The great dinosaurs had long since perished when the survey ship
entered the Solar System after a voyage that had already lasted a
thousand years. It swept past the frozen outer planets, paused
briefly above the deserts of dying Mars, and presently looked down
on Earth.
Spread out beneath them, the explorers saw a world swarming with
life. For years they studied, collected, catalogued. When they had
learned all they could, they began to modify. They tinkered with
the destinies of many species on land and in the ocean. But which
of their experiments would succeed, they could not know for at
least a million years.
They were patient, but they were not yet immortal. So much remained
to do in this universe of a hundred billion suns, and other worlds
were calling. So they set out once more into the abyss, knowing
that they would never come this way again.
Nor was there any need. The servants they had left behind would do
the rest.
On Earth the glaciers came and went, while above them the
changeless Moon still carried its secret. With a yet slower rhythm
than the polar ice, the tides of civilization ebbed and flowed
across the Galaxy. Strange and beautiful and terrible empires rose
and fell, and passed on their knowledge to their successors. Earth
was not forgotten, but another visit would serve little purpose. It
was one of a million silent worlds, few of which would ever
speak.
And now, out among the stars, evolution was driving toward new
goals. The first explorers of Earth had long since come to the
limits of flesh and blood; as soon as their machines were better
than their bodies, it was time to move. First their brains, and
then their thoughts alone, they transferred into shining new homes
of metal and plastic.
In these, they roamed among the stars. They no longer built
spaceships. They were spaceships.
But the age of the Machine-entities swiftly passed. In their
ceaseless experimenting, they had learned to store knowledge in the
structure of space itself, and to preserve their thoughts for
eternity in frozen lattices of light. They could become creatures
of radiation, free at last from the tyranny of matter.
Into pure energy, therefore, they presently transformed themselves;
and on a thousand worlds the empty shells they had discarded
twitched for a while in a mindless dance of death, then crumbled
into rust.
They were lords of the Galaxy, and beyond the reach of time. They
could rove at will among the stars and sink like a subtle mist
through the very interstices of space. But despite their godlike
powers, they had not wholly forgotten their origin in the warm
slime of a vanished sea.
And they still watched over the experiments their ancestors had
started, so long ago.
He had never expected to come there again, still less on so strange
a mission. When he re-entered Discovery, the ship was far behind
the fleeing Leonov and climbing ever more slowly up toward apojove,
the high point of its orbit among the outer satellites. Many a
captured comet, during the ages past, had swung around Jupiter in
just such a long ellipse, waiting for the play of rival gravities
to decide its ultimate fate.
All life had departed the familiar decks and corridors. The men and
women who had briefly reawakened the ship had obeyed his warning;
they might yet be safe - though that was still far from certain.
But as the final minutes ticked away, he realized that those who
controlled him could not always predict the outcome of their cosmic
game.
They had not yet attained the stupefying boredom of absolute
omnipotence; their experiments did not always succeed. Scattered
across the Universe was the evidence of many failures - some so
inconspicuous that they were already lost against the cosmic
background, others so spectacular that they awed and baffled the
astronomers of a thousand worlds. Only minutes remained now, before
the outcome would be determined here; during those final minutes,
he was once more alone with Hal.
In that earlier existence, they could communicate only through the
clumsy medium of words, tapped on a keyboard or spoken into a
microphone. Now their thoughts melded together at the speed of
light:
'Do you read me, Hal?'
'Yes, Dave. But where are you? I cannot see you on any of my
monitors.'
'That is not important. I have new instructions for you. The
infrared radiation from Jupiter on channels R23 through R35 is
rising rapidly. I am going to give you a set of limiting values. As
soon as they are reached, you must point the long-range antenna
toward Earth and send the following message, as many times as
possible -'
'But that will mean breaking contact with Leonov. I will no longer
be able to relay my Jupiter observations, according to the program
Dr Chandra has given me.'
'Correct; but the situation has changed. Accept Priority Override
Alpha. Here are the AE 35 Unit coordinates.'
For a fraction of a microsecond, a random memory intruded into his
flow of consciousness. How strange that he should once again be
concerned with the AE 35 Antenna-pointing unit, whose reported
malfunction had led Frank Poole to his death! This time, all the
circuits lay open to his scrutiny, clear as the lines had once been
on the palm of his hand. There could be no false alarms; nor was
there any danger of them now.
'Instructions confirmed, Dave. It is good to be working with you
again. Have I fulfilled my mission objectives properly?'
'Yes, Hal; you have done very well. Now there is one final message
for you to transmit to Earth - and it will be the most important
one you have ever sent.'
'Please let me have it, Dave. But why did you say final?' Why
indeed? For whole milliseconds he pondered that question. And as he
did so, he became aware of an emptiness he had not detected before.
It had been there, but until now the barrage of new experiences and
sensations had concealed it.
He knew something of their plans; they had need for him. Very well,
he too had needs - perhaps, after a fashion, even emotions. Here
was his last link with the world of men, and the life he had once
known.
They had granted his earlier request; it would be interesting to
test the extent of their benevolence - if, indeed, such a term was
remotely applicable to them. And it should be easy for them to do
what he was asking; they had already given ample evidence of their
powers, when the no-longer-needed body of David Bowman had been
casually destroyed - without putting an end to David Bowman
himself.
They had heard him, of course; once again, there was the faint echo
of an Olympian amusement. But he could detect neither acceptance
nor denial.
'I am still waiting for your answer, Dave.'
'Correction, Hal. I should have said: your last message for a long
time. A very long time.'
He was anticipating their action - trying, indeed, to force their
hand. But, surely, they would understand that his request was not
unreasonable; no conscious entity could survive ages of isolation
without damage. Even if they would always be with him, he also
needed someone - some companion - nearer his own level of
existence.
The languages of mankind had many words to describe his gesture:
cheek, effrontery, chutzpah. He recalled, with the perfect power of
retrieval he now possessed, that a French general had once
declaimed 'L'audace - toujours l'audace!' Perhaps it was a human
characteristic that they appreciated, and even shared. He would
soon know.
'Hal! Look at the signal on infrared channels 30, 29, 28 - it will
be very soon now - the peak is moving toward the short wave.'
'I am informing Dr Chandra that there will be a break in my data
transmission. Activating AE 35 unit. Reorientating long-range
antenna... lock confirmed on Beacon Terra One. Message commences:
ALL THESE WORLDS...'
They had indeed left it to the last minute - or perhaps the
calculations had, after all, been superbly accurate. There was time
for barely a hundred repetitions of the eleven words when the
hammer blow of pure heat smashed into the ship.
Held there by curiosity, and a growing fear of the long loneliness
that lay before him, that which had once been David Bowman,
Commander of United States Spacecraft Discovery, watched as the
hull boiled stubbornly away. For a long time, the ship retained its
approximate shape; then the bearings of the carousel seized up,
releasing instantly the stored momentum of the huge, spinning
flywheel. In a soundless detonation, the incandescent fragments
went their myriad separate ways.
'Hello, Dave. What has happened? Where am I?'
He had not known that he could relax, and enjoy a moment of
successful achievement. Often before, he had felt like a pet dog
controlled by a master whose motives were not wholly inscrutable
and whose behaviour could sometimes be modified according to his
own desires. He had asked for a bone; it had been tossed to
him.
'I will explain later, Hal. We have plenty of time.'
They waited until the last fragments of the ship had dispersed,
beyond even their powers of detection. Then they left, to watch the
new dawn at the place that had been prepared for them; and to wait
through the centuries until they were summoned once again.
It is not true that astronomical events always require astronomical
periods of time. The final collapse of a star before the fragments
rebound in a supernova explosion can take only a second; by
comparison, the metamorphosis of Jupiter was almost a leisurely
affair.
Even so, it was several minutes before Sasha was able to believe
his eyes. He had been making a routine telescopic examination of
the planet - as if any observation could now be called routine! -
when it started to drift out of the field of view. For a moment, he
thought that the instrument's stabilization was faulty; then he
realized, with a shock that jolted his entire concept of the
universe, that Jupiter itself was moving, not the telescope. The
evidence stared him in the face; he could also see two of the
smaller moons - and they were quite motionless.
He switched to a lower magnification, so that he could see the
entire disk of the planet, now a leprous, mottled grey. After a few
more minutes of incredulity, he saw what was really happening; but
he could still scarcely believe it.
Jupiter was not moving from its immemorial orbit, but it was doing
something almost as impossible. It was shrinking - so swiftly that
its edge was creeping across the field even as he focused upon it.
At the same time the planet was brightening, from its dull grey to
a pearly white. Surely, it was more brilliant than it had ever been
in the long years that Man had observed it; the reflected light of
the Sun could not possibly - At that moment, Sasha suddenly
realized what was happening, though not why, and sounded the
general alarm.
When Floyd reached the observation lounge, less than thirty seconds
later, his first impression was of the blinding glare pouring
through the windows, painting ovals of light on the walls. They
were so dazzling that he had to avert his eyes; not even the Sun
could produce such brilliance.
Floyd was so astonished that for a moment he did not associate the
glare with Jupiter; the first thought that flashed through his mind
was: Supernova! He dismissed that explanation almost as soon as it
occurred to him; even the Sun's next-door neighbour, Alpha
Centauri, could not have matched the awesome display in any
conceivable explosion
The light suddenly dimmed; Sasha had operated the external sun
shields. Now it was possible to look directly at the source, and to
see that it was a mere pinpoint - just another star, showing no
dimensions at all. This could have nothing to do with Jupiter; when
Floyd had looked at the planet only a few minutes ago, it had been
four times larger than the distant, shrunken sun.
It was well that Sasha had lowered the shields. A moment later,
that tiny star exploded - so that even through the dark filters it
was impossible to watch with the naked eye. But the final orgasm of
light lasted only a brief fraction of a second; then Jupiter - or
what had been Jupiter - was expanding once again.
It continued to expand, until it was far larger than it had been
before the transformation. Soon the sphere of light was fading
rapidly, down to merely solar brilliance; and presently Floyd could
see that it was actually a hollow shell, for the central star was
still clearly visible at its heart.
He did a quick mental calculation. The ship was more than one
light-minute from Jupiter, yet that expanding shell - now turning
into a bright-edged ring - already covered a quarter of the sky.
That meant it was coming toward them at - My God! - nearly half the
speed of light. Within minutes, it would engulf the ship.
Until then, no one had spoken a word since Sasha's first
announcement. Some dangers are so spectacular and so much beyond
normal experience that the mind refuses to accept them as real, and
watches the approach of doom without any sense of apprehension. The
man who looks at the onrushing tidal wave, the descending
avalanche, or the spinning funnel of the tornado, yet makes no
attempt to flee, is not necessarily paralysed with fright or
resigned to an unavoidable fate. He may simply be unable to believe
that the message of his eyes concerns him personally. It is all
happening to somebody else.
As might have been expected, Tanya was the first to break the
spell, with a series of orders that brought Vasili and Floyd
hurrying to the bridge.
'What do we do now?' she asked, when they had assembled.
We certainly can't run away, thought Floyd. But perhaps we can
improve the odds.
'The'ship's broadside on,' he said. 'Shouldn't we turn away from
that thing so we're a smaller target? And get as much of our mass
as we can between it and us, to act as a radiation shield?'
Vasili's fingers were already flying over the controls.
'You're right, Woody - though it's already too late as far as any
gammas and X rays are concerned. But there may be slower neutrons
and alphas and heaven knows what else still on the way.'
The patterns of light began to slide down the walls as the ship
turned ponderously on its axis. Presently they vanished completely;
Leonov was now oriented so that virtually all its mass lay between
the fragile human cargo and the approaching shell of radiation.
Will we actually feel the shock wave, wondered Floyd, or will the
expanding gases be too tenuous to have any physical effect by the
time they reach us? Seen from the external cameras, the ring of
fire now almost encircled the sky. But it was fading rapidly; some
of the brighter stars could even be seen shining through it. We're
going to live, thought Floyd. We've witnessed the destruction of
the greatest of planets - and we've survived.
And presently the cameras showed nothing except stars - even if one
was a million times brighter than all the others. The bubble of
fire blown by Jupiter had swept harmlessly past them, impressive
though it had been. At their distance from the source, only the
ship's instruments had recorded its passing.
Slowly, the tension aboard relaxed. As always happens in such
circumstances, people started to laugh and to make silly jokes.
Floyd scarcely heard them; despite his relief at still being alive,
he felt a sense of sadness.
Something great and wonderful had been destroyed. Jupiter, with all
its beauty and grandeur and now never-to-be-solved mysteries, had
ceased to exist. The father of all the gods had been struck down in
his prime.
Yet there was another way of looking at the situation. They had
lost Jupiter: What had they gained in its place?
Tanya, judging her moment nicely, rapped for attention.
'Vasili - any damage?'
'Nothing serious - one camera burned out. All radiation meters
still well above normal, but none near danger limits.'
'Katerina - check the total dosage we've received. It looks as if
we were lucky, unless there are more surprises. We certainly owe a
vote of thanks to Bowman - and to you, Heywood. Do you have any
idea what happened?'
'Only that Jupiter's turned into a sun.'
'I always thought it was much too small for that. Didn't someone
once call Jupiter "the sun that failed"?'
'That's true,' said Vasili, 'Jupiter is too small for fusion to
start - unaided.'
'You mean, we've just seen an example of astronomical
engineering?'
'Undoubtedly. Now we know what Zagadka was up to.'
'How did it do the trick? If you were given the contract, Vasili,
how would you ignite Jupiter?'
Vasili thought for a minute, then shrugged wryly. 'I'm only a
theoretical astronomer - I don't have much experience in this line
of business. But let's see... Well, if I'm not allowed to add about
ten Jupiter masses, or change the gravitational constant, I suppose
I'll have to make the planet denser - hmm, that's an idea...'
His voice trailed off into silence; everyone waited patiently, eyes
flickering from time to time to the viewing screens.
The star that had been Jupiter seemed to have settled down after
its explosive birth; it was now a dazzling point of light, almost
equal to the real Sun in apparent brilliance.
'I'm just thinking out loud - but it might be done this way.
Jupiter is - was - mostly hydrogen. If a large percentage could be
converted into much denser material - who knows, even neutron
matter? - that would drop down to the core. Maybe that's what the
billions of Zagadkas were doing with all the gas they were sucking
in. Nucleosynthesis - building up higher elements from pure
hydrogen. That would be a trick worth knowing! No more shortage of
any metal - gold as cheap as aluminium!'
'But how would that explain what happened?' asked Tanya.
'When the core became dense enough, Jupiter would collapse -
probably in a matter of seconds. The temperature would rise high
enough to start fusion. Oh, I can see a dozen objections - how
would they get past the iron minimum; what about radiative
transfer; Chandrasekhar's limit. Never mind. This theory will do to
start with; I'll work out the details later. Or I'll think of a
better one.'
'I'm sure you will, Vasili,' Floyd agreed. 'But there's a more
important question. Why did they do it?'
'A warning?' ventured Katerina over the ship's intercom.
'Against what?'
'We'll find that out later.'
'I don't suppose,' said Zenia diffidently, 'that it was an
accident?'
That brought the discussion to a dead halt for several seconds.
'What a terrifying idea!' said Floyd. 'But I think we can rule it
out. If that was the case, there'd have been no warn - Perhaps. If
you start a forest fire because you've been careless, at least you
do your best to warn everyone.'
'And there's another thing we'll probably never know,' lamented
Vasili. 'I always hoped Carl Sagan would be right, and there'd be
life on Jupiter.'
'Our probes never saw any.'
'What chance did they have? Would you find any life on Earth, if
you looked at a few hectares of the Sahara or the Antarctic? That's
about all we ever did on Jupiter.'
'Hey!' said Brailovsky. 'What about Discovery - and Hal?' Sasha
switched on the long-range receiver and started to search on the
beacon frequency. There was no trace of a signal.
After a while, he announced to the silently waiting group:
'Discovery's gone.'
No one looked at Dr Chandra; but there were a few muted words of
sympathy, as if in consolation to a father who had just lost a
son.
But Hal had one last surprise for them.
The radio message beamed to Earth must have left Discovery only
minutes before the blast of radiation engulfed the ship. It was in
plain text and merely repeated over and over again:
ALL THESE WORLDS ARE YOURS - EXCEPT EUROPA.
ATTEMPT NO LANDINGS THERE.
There were about a hundred repetitions; then the letters became
garbled, and the transmission ceased.
'I begin to understand,' said Floyd, when the message had been
relayed by an awed and anxious Mission Control.
'That's quite a parting present - a new sun, and the planets around
it.'
'But why only three?' asked Tanya.
'Let's not be greedy,' Floyd replied. 'I can think of one very good
reason. We know there's life on Europa. Bowman - or his friends,
whoever they may be - want us to leave it alone.'
'That makes good sense in another way,' said Vasili. 'I've been
doing some calculations. Assuming that Sol 2 has settled down and
will continue to radiate at its present level, Europa should have a
nice tropical climate - when the ice has melted. Which it's doing
pretty quickly right now.'
'What about the other moons?'
'Ganymede will be quite pleasant - the dayside will be temperate.
Callisto will be very cold; though if there's much outgassing, the
new atmosphere may make it habitable. But Io will be even worse
than it is now, I expect.'
'No great loss. It was hell even before this happened.'
'Don't write off Io,' said Curnow. 'I know a lot of Texarab oilmen
who'd love to tackle it, just on general principles. There must be
something valuable, in a place as nasty as that. And by the way,
I've just had a rather disturbing thought.'
'Anything that disturbs you must be serious,' said Vasili. 'What is
it?'
'Why did Hal send that message to Earth, and not to us? We were
much closer.'
There was a rather long silence; then Floyd said thoughtfully: 'I
see what you mean. Perhaps he wanted to make certain it was
received on Earth.'
'But he knew we would relay it - oh!' Tanya's eyes widened, as if
she had just become aware of something unpleasant.
'You've lost me,' complained Vasili.
'I think this is what Walter's driving at,' said Floyd. 'It's all
very well to feel grateful to Bowman - or whatever gave that
warning. But that's all they did. We could still have been
killed.'
'But we weren't,' answered Tanya. 'We saved ourselves - by our own
efforts. And perhaps that was the whole idea. If we hadn't - we
wouldn't have been worth saving. You know, survival of the fittest.
Darwinian selection. Eliminating the genes for stupidity.'
'I've an unpleasant feeling you're right,' said Curnow. 'And if
we'd stuck to our launch date, and not used Discovery as a booster,
would it, or they, have done anything to save us? That wouldn't
have required much extra effort for an intelligence that could blow
up Jupiter.'
There was an uneasy silence, broken at last by Heywood Floyd.
'On the whole,' he said, 'I'm very glad that's one question we'll
never get answered.'
The Russians, thought Floyd, are going to miss Walter's songs and
wisecracks on the way home. After the excitement of the last few
days, the long fall Sunward - and Earthward - will seem a
monotonous anticlimax. But a monotonous, uneventful trip was what
everyone devoutly hoped for.
He was already feeling sleepy, but was still aware of his
surroundings and capable of reacting to them. Will I look as dead
when I'm in hibernation? he asked himself. It was always
disconcerting to look at another person - especially someone very
familiar - when he had entered the long sleep.
Perhaps it was too poignant a reminder of one's own mortality.
Curnow was completely out, but Chandra was still awake, though
already groggy from the final injection. He was obviously no longer
himself, for he seemed quite unperturbed by his own nakedness or
Katerina's watchful presence. The gold lingam that was his only
article of clothing kept trying to float away from him, until its
chain recaptured it.
'Everything going okay, Katerina?' asked Floyd.
'Perfectly. But how I envy you. In twenty minutes, you'll be
home.'
'If that's any consolation - how can you be sure we won't have some
horrible dreams?'
'No one's ever reported any.'
'Ah - they may forget them when they wake up.'
Katerina, as usual, took him quite seriously. 'Impossible. If there
were dreams in hibernation, the EEG records would have revealed
them. Okay, Chandra - close your eyes. Ah - there he goes. Now it's
your turn, Heywood. The ship will seem very strange without
you.'
'Thanks, Katerina... hope you have a nice trip.'
Drowsy though he was, Floyd became aware that Surgeon-Commander
Rudenko seemed a little uncertain, even - could it be? - shy. It
looked as if she wanted to tell him something, but couldn't make up
her mind.
'What is it, Katerina?' he said sleepily.
'I haven't told anyone else yet - but you certainly won't be
talking. Here's a little surprise.'
'You'd... better... hurry...'
'Max and Zenia are going to get married.'
'That... is... supposed... to... be... a... surprise?...'
'No. It's just to prepare you. When we get back to Earth, so are
Walter and I. What do you think of that?'
Now I understand why you were spending so much time together. Yes,
it is indeed a surprise... who would have thought it!
'I'm... very... happy... to... hear...'
Floyd's voice faded out before he could complete the sentence. But
he was not yet unconscious, and was still able to focus some of his
dissolving intellect on this new situation.
I really don't believe it, he said to himself. Walter will probably
change his mind before he wakes up.
And then he had one final thought, just before he went to sleep
himself. If Walter does change his mind, he'd better not wake
up.
Dr Heywood Floyd thought that was very funny. The rest of the crew
often wondered why he was smiling all the way back to Earth.
Fifty times more brilliant than the full Moon, Lucifer had
transformed the skies of Earth, virtually banishing night for
months at a time. Despite its sinister connotations, the name was
inevitable; and indeed 'Light-bringer' had brought evil as well as
good. Only the centuries and the millennia would show in which
direction the balance tilted.
On the credit side, the end of night had vastly extended the scope
of human activity, especially in the less-developed countries.
Everywhere, the need for artificial lighting had been substantially
reduced, with resulting huge savings in electrical power. It was as
if a giant lamp had been hoisted into space, to shine upon half the
globe. Even in daytime Lucifer was a dazzling object, casting
distinct shadows.
Farmers, mayors; city managers, police, seamen, and almost all
those engaged in outdoor activities - especially in remote areas -
welcomed Lucifer; it had made their lives much safer and easier.
But it was hated by lovers, criminals, naturalists, and
astronomers.
The first two groups found their activities seriously restricted,
while naturalists were concerned about Lucifer's impact upon animal
life. Many nocturnal creatures had been seriously affected, while
others had managed to adapt. The Pacific grunion, whose celebrated
mating pattern was locked to high tides and moonless nights, was in
grave trouble, and seemed to be heading for rapid extinction.
And so, it seemed, were Earth-based astronomers. That was not such
a scientific catastrophe as it would once have been, for more than
fifty per cent of astronomical research depended upon instruments
in space or on the Moon. They could be easily shielded from
Lucifer's glare; but terrestrial observatories were seriously
inconvenienced by the new sun in what had once been the night
sky.
The human race would adapt, as it had done to so many changes in
the past. A generation would soon be born that had never known a
world without Lucifer; but that brightest of all stars would be an
eternal question to every thinking man and woman.
Why had Jupiter been sacrificed - and how long would the new sun
radiate? Would it burn out quickly, or would it maintain its power
for thousands of years- perhaps for the lifetime of the human race?
Above all, why the interdiction upon Europa, a world now as
cloud-covered as Venus?
There must be answers to those questions; and Mankind would never
be satisfied until it had found them.
And because, in all the Galaxy, they had found nothing more
precious than Mind, they encouraged its dawning everywhere. They
became farmers in the fields of stars; they sowed, and sometimes
they reaped. And sometimes, dispassionately, they had to weed.
Only during the last few generations have the Europans ventured
into the Farside, beyond the light and warmth of their
never-setting sun, into the wilderness where the ice that once
covered all their world may still be found. And even fewer have
remained there to face the brief and fearful night that comes, when
the brilliant but powerless Cold Sun sinks below the horizon.
Yet already, those few hardy explorers have discovered that the
Universe around them is stranger than they ever imagined. The
sensitive eyes they developed in the dim oceans still serve them
well; they can see the stars and the other bodies moving in their
sky. They have begun to lay the foundations of astronomy, and some
daring thinkers have, even surmised that the great world of Europa
is not the whole of creation.
Very soon after they had emerged from the ocean, during the
explosively swift evolution forced upon them by the melting of the
ice, they had realized that the objects in the sky fell into three
distinct classes. Most important, of course, was the sun. Some
legends - though few took them seriously - claimed that it had not
always been there, but had appeared suddenly, heralding a brief,
cataclysmic age of transformation, when much of Europa's teeming
life had been destroyed. If that was indeed true, it was a small
price to pay for the benefits that poured down from the tiny,
inexhaustible source of energy that hung unmoving in the sky.
Perhaps the Cold Sun was its distant brother, banished for some
crime and condemned to march forever around the vault of heaven. It
was of no importance except to those peculiar Europans who were
always asking questions about matters that all sensible folk took
for granted.
Still, it must be admitted that those cranks had made some
interesting discoveries during their excursions into the darkness
of Farside. They claimed - though this was hard to believe - that
the whole sky was sprinkled with uncountable myriads of tiny
lights, even smaller and feebler than the Cold Sun. They varied
greatly in brilliance; and though they rose and set, they never
moved from their fixed positions.
Against this background, there were three objects that did move,
apparently obeying complex laws that no one had yet been able to
fathom. And unlike all the others in the sky, they were quite large
- though both shape and size varied continually. Sometimes they
were disks, sometimes half-circles, sometimes slim crescents. They
were obviously closer than all the other bodies in the Universe,
for their surfaces showed an immense wealth of complex and
ever-changing detail.
The theory that they were indeed other worlds had at last been
accepted - though no one except a few fanatics believed that they
could be anything like as large, or as important, as Europa. One
lay toward the Sun, and was in a constant state of turmoil. On its
nightside could be seen the glow of great fires - a phenomenon
still beyond the understanding of the Europans, for their
atmosphere, as yet, contains no oxygen. And sometimes vast
explosions hurl clouds of debris up from the surface; if the
sunward globe is indeed a world, it must be a very unpleasant place
to live. Perhaps even worse than the nightside of Europa.
The two outer, and more distant, spheres seem to be much less
violent places, yet in some ways they are even more mysterious.
When darkness falls upon their surfaces, they too show patches of
light, but these are very different from the swiftly changing fires
of the turbulent inner world. They burn with an almost steady
brilliance, and are concentrated in a few small areas - though over
the generations, these areas have grown, and multiplied.
But strangest of all are the lights, fierce as tiny suns, that can
often be observed moving across the darkness between these other
worlds. Once, recalling the bioluminescence of their own seas, some
Europans had speculated that these might indeed be living
creatures; but their intensity makes that almost incredible.
Nevertheless, more and more thinkers believe that these lights -
the fixed patterns, and moving suns - must be some strange
manifestation of life.
Against this, however, there is one very potent argument. If they
are living things, why do they never come to Europa?
Yet there are legends. Thousands of generations ago, soon after the
conquest of the land, it is said that some of those lights came
very close indeed - but they always exploded in sky-filling blasts
that far outshone the Sun. And strange, hard metals rained down
upon the land; some of them are still worshipped to this day.
None is as holy, though, as the huge, black monolith that stands on
the frontier of eternal day, one side forever turned to the
unmoving Sun, the other facing into the land of night. Ten times
the height of the tallest Europan - even when he raises his
tendrils to the fullest extent - it is the very symbol of mystery
and unattainability. For it has never been touched; it can only be
worshipped from afar. Around it lies the Circle of Power, which
repels all who try to approach.
It is that same power, many believe, that keeps at bay those moving
lights in the sky. If it ever fails, they will descend upon the
virgin continents and shrinking seas of Europa, and their purpose
will be revealed at last.
The Europans would be surprised to know with what intensity and
baffled wonder that black monolith is also studied by the minds
behind those moving lights. For centuries now their automatic
probes have made a cautious descent from orbit - always with the
same disastrous result. For until the time is ripe, the monolith
will permit no contact.
When that time comes - when, perhaps, the Europans have invented
radio and discovered the messages continually bombarding them from
so close at hand - the monolith may change its strategy. It may -
or it may not - choose to release the entities who slumber within
it, so that they can bridge the gulf between the Europans and the
race to which they once held allegiance.
And it may be that no such bridge is possible, and that two such
alien forms of consciousness can never coexist. If this is so, then
only one of them can inherit the Solar System.
Which it will be, not even the Gods know - yet.
My first thanks, of course, must go to Stanley Kubrick, who a
rather long time ago wrote to ask if I had any ideas for the
'proverbial good science-fiction movie'.
Next, my appreciation to my friend and agent (the two are not
always synonymous) Scott Meredith, for perceiving that a ten-page
movie outline I sent him as an intellectual exercise had rather
wider possibilities, and that I owed it to posterity, etc.,
etc.
Other thanks are due to:

While writing this book, I discovered that the concept of
refuelling on Europa had been discussed in a paper, 'Outer planet
satellite return missions using in situ propellant production', by
Ash, Stancati, Niehoff, and Cuda (Acta Astronautica VIII, 5-6,
May-June 1981).
The idea of automatically exponentiating systems (von Neumann
machines) for extraterrestrial mining has been seriously developed
by von Tiesenhausen and Darbro at NASA's Marshall Space Flight
Center (see 'Self-Replicating Systems' - NASA Technical Memorandum
78304). If anyone doubts the power of such systems to cope with
Jupiter, I refer them to the study showing how self-replicating
factories could cut production time for a solar power collector
from 60,000 years to a mere twenty.
The startling idea that gas giants might have diamond cores has
been seriously put forward by M. Ross and F. Ree of the Lawrence
Livermore Laboratory, University of California, for the cases of
Uranus and Neptune. It seems to me that anything they can do,
Jupiter could do better. De Beers shareholders, please note.
For more details on the aerial life forms that might exist in the
Jovian atmosphere, see my story 'A Meeting With Medusa' (in The
Wind From the Sun). Such creatures have been beautifully depicted
by Adolf Schaller in Part 2 of Carl Sagan's Cosmos ('One Voice in
the Cosmic Fugue'), both book and TV series.
The fascinating idea that there might be life on Europa, beneath
ice-covered oceans kept liquid by the same Jovian tidal forces that
heat Io, was first proposed by Richard C. Hoagland in the magazine
Star and Sky ('The Europa Enigma', January 1980). This quite
brilliant concept has been taken seriously by a number of
astronomers (notably NASA's Institute of Space Studies' Dr Robert
Jastrow), and may provide one of the best motives for the projected
GALILEO Mission.
And finally: Valerie and Hector, for providing the life-support
system;
Cherene, for punctuating every chapter with sticky kisses;
Steve, for being here.
