There's one on each side. This has been done on one or two other rockets
of similar vintage; I think the Thor did it that way, and there are vernier
engines among the clutter of nozzles at the base of the Russian "A" booster.
They were for roll control, especially after booster-engine dropoff when
there was only one main engine still firing, and for final trajectory
adjustments. At the time Atlas was built, they weren't confident of
being able to shut main engines down very precisely, and ICBMs need a
very precise final velocity vector.
I believe one of GD's improved-Atlas designs now in the works finally
gets around to deleting them. The precision issue is unimportant now
that there is always an upper stage doing the final boost. They must
be doing something about roll control, but I imagine it's a lot smaller
and lighter.

No, it just means they asked some pedantic twit of a rocket engineer.
He wasn't even entirely right.
There is a peculiar belief in some rocket-engineering circles that what
really defines an "engine" is not combustion chamber or nozzle but pumps.
So if two engines share pumps, they are really only one engine.
Ignoring a few of the very earliest test flights (which had no sustainer
engine), all Atlases have three main engines: two boosters and a sustainer.
*Some* (not all!) versions of Atlas have the two booster engines sharing
pumps. I don't know, offhand, which way the currently-operational Atlas
variants do it.

We're talking about a mission out to infinity (well, pretty much) with
no orbital phase. Clearly, at some point the thing will have just enough
velocity to make orbit, if that's what you were trying to do. However,
there is no requirement that this be at a stage break. The question is
not whether T4+C can put a Centaur into orbit, but whether T4+C+C gives
higher final velocity than T4+C. You lose some because the earlier
stages are pushing a heavier load, perhaps enough that the second
Centaur starts firing before orbital velocity is reached. You gain
some from having another high-energy stage; PFF *is* a rather flyweight
payload for this big booster, and putting some more mass into another
stage might be a net win.
>Regardless, the Titan IV was not structurally designed to carry that much

I'm sure the Titan II designers would make the same comment about the
poor little slightly-uprated Titan II that sits in the middle of the
Titan IV. Doesn't mean it can't be done, only that you have to think
about it hard before deciding.
However, this is a good question, and the answer is probably "no", because
Titan IV is structurally a rather marginal design, I'm told. Reportedly,
only about 90 days a year have sufficiently mild high-altitude winds for
a Titan IV launch to be permissible.

Hmm... Interesting... I did not know that he was assassinated. Look what
I got from the book SPACE, Canada in the 20th Century by Christopher
G. Trump;
"In [Gerald Bull] own words: 'I had been given U.S. citizenship by an
act of Congress and was then accused of treason for trying to sell my
output to the Saudi Arabians. But I am still a Canadian - I will always be a
Canadian. They allowed to plead guilty in the U.S. court for selling a 60
year-old Caribbean radar set to South Africa. After that they sent me to
that "gulag" (prison camp) in Allentown, PA, where I served three
months.'
"An irrepressible man", the book continues, "Bull still maintains a
home in Quebec, but also does most of his business in Spain and
Belegium. He also has a major rocket research programme underway
in China."
Since the book was published in 1987 I do not doubt that Bull was
subsequently assassinated...

The "Ram Tube" as Dave Stephenson called it is actually the "Ram Accelerator"
being developed at the Univ. of Washington since 1984. The ram accelerator
is also being developed at the Army Research Lab in Aberdeen, MD (120mm
diam. bore), Eglin Air Force Base (93mm) and at the Institute de Saint Louis in
France (90mm and 20 mm).
Except for the Eglin facility, all are working and producing interesting results
(Eglin's facility is not yet completed). No one has yet scaled the device up to
space-launch usable (> 1 meter diam.) dimensions yet though.
Current feelings are that the ram accelerator is capable of 7 Km/s which is
good enough to get to LEO.
Additional note,
John? Hunter at Livermore is using a scaled-up two-stage light gas gun to get
projectiles up to high velocities to put payloads into LEO, but the drawback
to this method is high g loading of the payload (>50,000 g's).
The ram accelerator has the
ability to "soft launch" projectiles (meaning peak g loading under 10,000 g's)
theoretically and is one of it's major advantages over other technologies.
The advantage of the light gas gun is that it is simple technolgy that is just
scaled up in size. The disadvantage of scaling up a light gas gun is that it
suffers from the "squared-cubed" law of scaling and hence does not scale
well.
Recently Hunter's group was given a set back when their breech or pump tube
ruptured when the pressure inside it rose too high from unexpectedly
rapid combustion. He is rebuilding though.

I've wondered about this for a long time. For space missions lasting
months or years, wouldn't it be more efficient to use small astronauts?
The beds and other equipment can be smaller or, in the case of
off-the-shelf equipment, the astronauts would get less claustrophobic.
Food requirements would be less (somebody help me out on this). Anything
in space flight that now requires classical human muscle could be done
by a machine. The limiting factor (for colony flights!) would probably
be the size at which a woman can deliver a baby without complications.
Large astronauts seem to come from (1) SF magazines that wanted heroic
types and (2) current pilot-training requirements, which evolved from
the military. Neither of those reasons is carved in stone.

Subject: Space Station Aldrin
Newsgroups: sci.space
This is a summary of a Feb 15 article in the New York Times.
From the MIT Tech Talk:
Edwin E. (Buzz) Aldrin Jr., the MIT alumnus (ScD, 1963) who walked on the moon
as an astronaut in 1969, has received a patent for a permanent space station
he designed in his office at home.
The New York Times (Feb 15) reported that Dr. Aldrin, who went to the moon with
Neil Armstrong on the Apollo 11 mission, wants his space station to be the core
of a "complete family of spacecraft that support it."
The story continued: "Mr. Aldrin's design, though large enough for a crew of
8 to 10 astronauts, can be launched in one piece and then unfolded in space."
Because it would rely on a large rocket like the Saturn 5, which the US no
longer uses, he hopes for eventual cooperation with the Russian space
program, which still has a powerful rocket capable of putting a heavy
payload into space.

Matthew, you missed the entire point of my posting. Please go read it again.
I'm not suggesting that these relatively small initial ventures will, by
themselves, make a big difference to the Russian economy. Ultimately, the
Russians are going to have to sort most of it out themselves. That will
not be easy. Holding a political consensus together long enough to do it
will not be easy either. The West can contribute far more in hope and
incentive -- things to look forward to if people sweat and struggle for a
few years -- than it can in money. But vague mumblings from the White
House or Brussels, or vague half-disbelieved notions of how the West lives,
are not enough.
As a non-space example, the single biggest thing the European Common
Market could do to help the ex-satellite nations, and even the CIS states
themselves, would not involve a single penny of cross-border cash flow:
far more valuable than any form of direct aid would be a firm commitment
to a specific set of unambiguous requirements for allowing those nations
into the Common Market.
The aim of cooperative ventures in the near future should not be to prop
up the Russian economy, but to establish the possibility of more ("we *are*
willing to cut real deals, not just charity") and to make it clear how that
would happen ("but you're going to have to fix this, this, and this first").

The relevant export rules are set in Ottawa, not in Washington.
However, with occasional exceptions (e.g. trade with Cuba, where Canada
didn't share the US's hysterical reaction to Castro), Canadian export
rules tend to be pretty similar to US ones.
It is also possible for US rules to apply to Canadian exports because
there is significant US content in the product being exported, and the
export of those bits to Canada was conditional on any re-export complying
with US rules. (This sort of thing is why the US has such clout in the
question of who is allowed to launch Western commercial satellites --
it's rare to find such a bird that lacks significant US technology.)

TOPEX/POSEIDON OBSERVES GIANT WAVES IN STORM OF THE CENTURY
As the "storm of the century" hit the eastern part of the United States
on March 14, giant waves measuring up to approximately 40 feet (12 meters) high
were observed in the North Atlantic by the U.S.-French TOPEX/POSEIDON
satellite.
The highest waves measured by the radar altimeter onboard the satellite
were observed halfway between the United States and Europe at the latitude of
New York City - approximately 41 degrees North. Strong winds of 45 miles per
hour (20 meters per second) also were recorded in the high waves vicinity.
"The TOPEX/POSEIDON mission studies the dynamics of the world's
ocean currents by measuring the shape of the sea surface using a radar
altimeter," said Dr. Lee Fu, Project Scientist at NASA's Jet Propulsion
Laboratory, Pasadena, Calif.
"The height of the waves and the speed of the wind over the ocean also
are measured by the radar as byproducts of the mission," he continued.
Measuring sea level allows oceanographers to study changes in ocean currents
and global circulation and to determine how those changing currents affect
world climate.
In related activities, scientists at the Naval Research Laboratory in
Mississippi report that their recent analysis of TOPEX/POSEIDON data, as well
as measurement taken by tide gauges and buoys confirms that the Kelvin wave
pulse that they predicted in February has arrived at the South American coast
as they anticipated.
A Kelvin wave is a large warm water mass that moves along the equator
in the Pacific Ocean. These pulses sometimes contribute to El Nino conditions
in the eastern equatorial Pacific.
JPL manages the NASA portion of the TOPEX/POSEIDON mission for
NASA's Office of Mission to Planet Earth. Launched Aug. 10, 1992 from Kourou,
French Guiana, TOPEX/POSEIDON is the second satellite in the Mission to
Planet Earth Program, NASA's long-term effort to study Earth as a global
environmental system.

If you're going to have to live inside domes -- especially such massive

is little point to large-scale meddling with Venus unless it can be

WORKSHOP ON SOFTWARE FOR SATELLITE AUTONOMY
ALBUQUERQUE, NM
JUNE 22-25, 1993
The American Institute of Aeronautics and Astronautics (AIAA) is sponsoring a
workshop on software technologies for satellite autonomy with support by the
Air Force Phillips Laboratory. The purpose of the workshop is to gather
information and facilitate communication amongst industry and other government
organizations regarding candidate technologies which may have applicability in
the development of increasingly autonomous spacecraft. It is anticipated that
the workshop will develop a roadmap which will include objectives, goals, and
timelines for further government/industry efforts in satellite autonomy. It is
further hoped that a baseline will be established for future cooperative
government/industry research efforts to increase spacecraft autonomy in areas
such as navigation, health and status monitoring, anomaly resolution, and
threat assessment/response.
A small registration fee (approximately $100) will be asked.
POSITION PAPER SUBMISSION: Workshop attendance will be based on position
paper submissions. Interested participants should submit a short paper
(not to exceed 1000 words) describing their position and interests regarding
software technologies applicable to spacecraft autonomy. Position papers
should include no proprietary or classified information and should be
suitable for publication in the proceedings with permission to print.
Some participants will be chosen to present their positions at the
workshop. Interested parties should submit their position papers no later
than 30 April 1993 to:

I think a lot of the economics going around these days is at the
equivalent level that medicine was in when it was unneccesary for
a medical student (who were the _medical professionals_ as opposed
to midwives given the job) to wash his hand between disecting the
corpse of a leper and assisting a woman in labor (although I wonder:
was he just there to make sure the kid caught something and died,
before he moved on to the next patient? I mean, what good could he
do, compared to the bad he was doing? The Nineteenth century in
Europe, because of this practice, had an abnormally high infant
mortality rate).
Getting back to economics, many people in both parties seem to be
operating at the level of the "broken window" fallacy, or worse.
