Note, though, that they spent a good bit of their own money on it while
it was going.  I.e., it looked like a serious possibility.  If they'd had
all the flight opportunities they wanted, when they wanted them, the end
of the story might have been different.

Note that although Trump is unimaginably rich, and unquestioniably the most
famous billionaire in America today, his personal fortune is estimated at
"only" around $ 1.7 billion.  While this is an incredible amount of money,
it's not enough to run a personal space program.

Trump has made a name for himself as an effective manager of big projects,
though, and perhaps this is where he'd be most useful.

'dja ever notice how everybody refers to it as _THE_ station?  Why only
one, huh?  If DoD wants one, give it to 'em; if we need one for medical
research, dedicate a station for the purpose; if the exotic materials
people require better microgravity than DoD can guarantee in _its_
station, we'll build a separate station (compact, for the low gravity
gradient) for materials research.

Putting all our eggs in the basket of one space station sounds about
as smart as depending on one launch system (remember the Shuttle?).
Look at some of the problems caused by having only one station:

1) It has to be _perfect_ the first time around.  Of course, this isn't
   a real practical attitude.

2) It has to do everything!  Multipurpose tools aren't always useful;
   the classic example is the 100-bladed Swiss army knife.

Besides, It may look like it would cost more to build several smaller
stations, but the synergy among multiple program teams (exchange of
personnel, and (hopefully) good-natured competition) would be better
than having a single, humongous program office pronouncing the One True
Way (tm) of conquering space.

>Our real space efforts--planetary exploration, new technology, microgravity
>research, privatization, etc. etc.--do not at all rely on the Station.

I tend to agree, but by now it's politically infeasible to change horses
in midstream.

Yes. The Taurus (MX plus Pegasus) now under development for DARPA "would
be capable of sending 925 lb payloads on Earth escape trajectories to
the Moon."
 "JPL has begun examining the type of small spacecraft that could be
used in the 21st century for such high velocity, low cost missions to
the planets." (AW&ST, 18-9-89, p.50)
 Sounds like Dyson's "Astrochicken" to me.

Apollo was mounted within 5-10 years of proposal. It can be done if
the political will exists.

No they haven't. There is an article in the current Economist which gives
figures but the partners are spending billions on the station.

I've got news for you, Nick:  they're spending their own billions on it,
and the US gets quite a bit of use of the facilities they're supplying.
On terms that they aren't too happy about, either.

Subject: Soviet commercial space groups

We have been setting up some space services deals with the Soviets
and had been dealing with Glavcosmos. The Soviets have just informed
us that they have created two agencies, the Estonian Aero-Space
Agency and the Dniepepotrovsk Rocket and Space Scientific Test Centre
to deal with commercial space projects. We are to deal with these
groups instead of Glavcosmos. I am assuming these groups existed
before, and are now being utilized for this new purpose. I will update
as I get more info.

Subject: Leap Second
X-Vms-Mail-To: EXOS%"[e-mail]"

Information from Herb Royden here which may be useful to you folk
with ephemeris programs, or super-accurate system clocks:

----------------------------------------------------------------

The International Earth Rotation Service (IERS) has announced that a positive
leap second will occur at the end of December 1989. Details are given in IERS
Bulletin C (11 September 1989), as follows:


              UTC TIME STEP on the 1st of January 1990

A positive leap second will be introduced at the end of December 1989.
The sequence of dates of the UTC second markers will be :
                 1989 December 31,   23h 59m 59s
                 1989 December 31,   23h 59m 60s
                 1990 January   1,    0h  0m  0s
The difference between UTC and the International Atomic Time TAI is :
from 1988 January 1, 0h UTC, to 1990 January 1, 0h UTC    : UTC-TAI = - 24s
from 1990 January 1, 0h UTC, until further notice    : UTC-TAI = - 25s


This UTC step will be incorporated into future STOIC output files (UniSys
elements) starting with last Monday's, having

TIMPOL='STOIC.LD890929/PT891023 .LAST DATUM 890929 PREDICTS TO 891023.   ',

as the first record. The value of TAI - UTC will increase from exactly 24 sec
(88/01/0189/12/31) to exactly 25 sec (90/01/01). The value of UT1 - UTC will
jump from roughly -0.7 to +0.3 sec. The value of ET - UTC will increase from
approximately 56.184 to 57.184 sec.

Subject: MARS OBSERVER INSTRUMENTS

AVIATION WEEK -- just broke down and finally got a subscription, since
I like aircraft too IT'S ALL GRAVY! -- in their latest issue did some
closeups on future American space probes; great article on Mars
observer, which however leaves me with some questions about the
instrumentation payload:

  * Gamma ray spectrometer:  No problem there, detects elemental
    composition and distribution of planetary surface by sensing
    gamma rays due to fluorescence of the surface under cosmic-ray
    bombardment.  (Operating principles unkown.)

  * Laser altimeter:  Probably uses radar-like action, using laser
    light instead of radio waves.

  * Pressure modulator infrared radiometer: Huh?

  * Thermal emission spectrometer:  An IR spectrometer?

  * Camera.

  * Electron reflectometer: Say what?

  * Magnetometers:  Magnetic field sensors, probably using an
    inductive pickup.

Anybody who can elaborate on, clarify, correct, or otherwise enlighten
me on these nice toys would have my appreciation.  Please email unless
you feel your response would be of general interest ...
