This is kind of a shame.  Voyager was the CAMERA of the decade.
The JPL imaging team are the PHOTOGRAPHERS of the decade...

Ah, I see.  The apology makes everything all right.  I wonder if the
mujahidin would agree, though, since the (Soviet-backed) Afghan government
is continuing the slaughter without apology.

Has Uncle Gorby apologized for the Gulag yet?

For some reason, I find it difficult to be horrified at a few months'
smugness about a few thousand deaths while dismissing most of a decade's
smugness about the mass slaughter and systematic devastation in Afghanistan.
Between the dead and the refugees, Afghanistan's population dropped 25-30%
in the last decade.  Its economy is in ruins, to put it mildly.  Nasty little
legacies like millions of unmarked land mines will be there for decades.
And the war continues.  In most ways, China is paradise by comparison.
The consequences of Afghanistan were not particularly hard; the West's
economic expediency came through for the USSR despite the initial fuss.
And now that Gorbachev has apologized, let's let bygones be bygones?

I have tried to convince myself that the protest/sanctions/embargo/etc
uproar over China is not just the latest trendy cause, endorsed by the
same people who were outraged about US policies in Central America but
changed the subject whenever the word "Afghanistan" was heard, and
that there is some rational reason for drastic response to ugly and
vicious but comparatively minor repression... but I can't.

Being a little less cynical for the moment...  Trade policy should not be
based on the whims of the moment; consistency and continuity are important.
The space industry has been particularly plagued by policy-of-the-week
decision-making in recent years.  Encouraging though the fresh air in
Eastern Europe is, and disgusting though the graveyard stench in China is,
both are very recent developments.  Next year things may well be reversed.
It would be reasonable to discourage new Long March launch agreements
until trends in China are clearer, but existing agreements which have
already received formal approval should not be retroactively disapproved
(especially without compensation) except in a dire emergency.

The F-15 based weapon is called the "Homing Vehicle".  The spiderweb-like thing
was used in the "Homing Overlay Experiment".  These are completely different
machines, but they both demonstrate that the "hit a bullet with a bullet"
argument against ABM has been made impotent and obsolete by semiconductor
silicon.  Though SSI and MSI digital logic were available to the designers
of the last ABM's before the treaty, that's nothing compared to what we have
today.

A couple of years ago OMNI magazine had a brief report on continuing
anti-gravity research in Australia ( if I remember correctly ). The
report said that there is a direct corrolation between electro-
negativity and the masses response to gravity. It seems that materials
in a certain group ( charge-wise ) don't fall as fast as all others.
The results were obtained by dropping objects inside an outrageously
long vacuum tube mounted inside a deep cavern. Rate differences where
often less than 0.1%, but they were convinced they were on to something.
On the other hand, can you believe a report in a sci-fi magazine?

Daily Status/KSC Payload Management and Operations 12-20-89


- STS-31R HST (at VPF) -

Began yesterday with construction of "wasp tent" to support
Wide Field Planetary Camera (WF/PC) installation.  WF/PC
installation is planned for today.  The every four hour wasp
inspection of the VPF highbay is continuing and will work through
the holiday week to ensure the problem has been resolved prior
to picking up with HST operations in January.

- STS-32R SYNCOM (at Pad A) -

Battery conditioning will continue through 23 December and will
pick back up again on 29 December.

- STS-35 ASTRO-1/BBXRT (at O&C) -

Software validation continues.  ASTRO-1 was successfully moved
from test stand 3 to cite test stand four.  There were no problems
encountered during the move.  Access platforms are being
installed followed by the cabling configuring of ASTRO-1 for cite
testing.

- STS-40 SLS-1 (at O&C) -

Rack pyrell foam replacement worked yesterday.  Rack 7 upper
mods, rack 9, 11, & 13 front mods were worked yesterday.  Module
pyrell foam replacement continues.

- STS-42 IML (at O&C) -

No activity.  Plan to pick up with rack mod work and staging
today.

Subject: Livermore space station query...

Several weeks ago, there was a posting citing a study done by Lawerence
Livermore laboratories stating that an inflatable Kevlar space station
could be produced and flown for $40 million.

Could someone send me enough information for me to get a copy of this
from them for myself?
( Like the real title, who wrote it, who it was presented to, who
commisioned it, etc??? )

Anything will be appreciated.

Thanx in advance.

                     GALILEO MISSION STATUS
                        December 20, 1989

     The Galileo spacecraft is 11.3 million miles or just over 1
light-minute from Earth today.  It is just over halfway (or about
93 million miles) along its path to Venus encounter, and is going
67,104 mph in its orbit. The spin configuration is in cruise mode,
with the upper part of the spacecraft spinning at 3.15 rpm around the
axis pointed within a couple of degrees of the Sun, and the lower part
despun, fixed in orientation.

     The EV-4 (Earth-Venus #4) sequence is currently in effect,
defining spacecraft operating states and functions. The celestial reference
loss and science alarm monitors are disabled as planned. The
telemetry rate is 1200 bits per second, and telemetry indicates
that all temperatures and pressures are at acceptable levels.
The spacecraft's attitude sun point angle is currently at 1.87 degrees,
plus or minus 0.3 degrees.

     The spacecraft DC voltage imbalance measurement, which
indicates the potential difference between the power busbars and
the spacecraft chassis, has been fluctuating. The DC bus voltage imbalance
has been slowly increasing and has reach nearly 17.3 volts. This does not
reflect a fluctuation in spacecraft electrical power, which
continues to show the normal margin.  Nor does it pose any hazard
to the spacecraft, which was designed to function at any level of
imbalance up to short-to-chassis; Voyager 1 has been operating
acceptably since early 1988 in this condition.

     On Friday the Galileo spacecraft will perform its
second trajectory change, moving the Venus closest approach
point to the desired 10,000 miles from planet center (about
6,200 miles above the cloud tops).  Closest approach will
occur about 10 p.m. PDT February 9.  At injection, the aim
point was biased out to several hundred miles from Venus.
This maneuver, will thrust mostly at right angles to the sun
line, with a magnitude of about 3/4 of 1 meter per second
(about 1/20 the first maneuver).  It will be done in four
segments or pulse chains, taking about 2-1/4 hours in all.

     All of the orbiter science instruments are off except for the
magnetometer and HIC.  Next week all the orbiter science instruments will
be checked out in a four-day programmed sequence, preparing
for Venus encounter.

A production system probably would work exactly that way. To hit an
orbiting body, your missile has to be at the right place at the right
time. (ie it has to intercept). Acheiving orbital velocity will not
aid this goal, and could make it more difficult.

It's definitely *cheaper* to just throw something "in front" of the
satellite.

There was one serious burial-in-space proposal.  It specified use of a
medium-altitude orbit, long-lived and in the thick of the Van Allen belts
where nobody else wants to operate.

Considering the enormous volume of natural debris already flying around
the solar system with unknown trajectories, it is unlikely that this would
be a significant issue.

This is, in fact, exactly what was done.  It's somewhat demanding for the
guidance system, but it is *much* easier to boost a payload to orbital
altitude than to get it to orbital speed, and the relative velocity is
high enough that you don't need a warhead.  The projectile was an infrared
seeker system with a ring of rocket motors around it, boosted by one or
two stages of big solid rocket after being dropped from a tuned-up F-15
in a steep supersonic climb.  It was quite a sensible design for an
antisatellite system, since you could hit any low orbit on a few hours'
notice by flying the F-15 to the right place.

Louis Friedman of the self-styled Planetary Society, writing in Aviation
Week a couple of years ago.  Exact reference can be dug up if needed.
Actually, almost any statement by the Planetary Society's overlords --
Sagan, Murray, Friedman -- in which they deign to mention the Moon
at all says the same thing:  "no further exploration worth doing at
this time -- ON TO MARS!".
