                         November 19, 1990

     The health of the Galileo spacecraft continues to be excellent.  Today,
another delta DOR (Differential One-way Ranging) navigation activity was
successfully completed using the 70 meter antenna pairs at Goldstone/Spain and
Goldstone/Australia.  Playback of Venus science data is presently in process.
Today, recorded data on tracks 1 and 2 will be returned at 28.8 Kbps.  The
remainder of the data playback activity will be performed on November 20 and
21.  Tomorrow, a No-Op command will be sent to reset the command Loss Timer.

Subject: space news from Sept 10 AW&ST etc.

Titan 4 launch from the Cape June 8 is now thought to have carried four
small payloads instead of a single big one.  At least one has maneuvered
into a higher orbit.  This might perhaps be an advanced version of the
Navy's White Cloud ocean surveillance system, which is known to use a
mother satellite with several auxiliaries.

Heavyweight aircraft of the month:  British Aerospace and the Soviet
Ministry of Aviation Industry propose reviving Hotol [!], using an
Antonov Mriya to carry a rocket-powered version of Hotol aloft, avoiding
the need for an advanced airbreathing engine.  Estimated payload to a
low near-equatorial orbit is 7 tons, and costs are estimated to be
about $2000/kg, roughly a third of that for Ariane 5.  Re-engining
Mriya with Rolls-Royce engines is being kept as a reserve possibility
against the chance that Hotol will gain weight in development.  The
Soviets are investigating the carry and separation aspects, and also
the possibility of using Soviet oxyhydrogen engines in Hotol.  BA is
looking into the modified Hotol, plus support and economics.  Both
sides consider it promising, and estimate an operational date circa
2000 if all goes well and funding (perhaps $4.6G) can be found.

Magellan under control after early mishaps, with causes still being
investigated.

Japan's BS-3A broadcastsat has lost one of its four power supply sectors,
the resulting 1.1kW power output being only marginally adequate for its
full mission.  The solar arrays appear to have deployed fully and on
schedule Aug 31, and the nature of the failure is somewhat mysterious.
This may be a headache for Japan's broadcasting plans, as BS-2 is near the
end of its life and the next BS-3 will not go up until next summer, even
assuming that it is not delayed for redesign of power systems.

Astro launch scrubs Sept 5 due to yet another hydrogen leak.  Another
attempt will be made Sept 17; win or lose [the latter], that will push
the Ulysses launch several days past the opening of its window Oct 5
unless NASA's normal three-week gap for data assessment is waived to
give Ulysses as much margin as possible.  [I believe the gap was waived
but Ulysses was late anyway, due to some other problem.  However, it's
on its way.]

NASA worried about a leak in one of Discovery's cooling systems, as a
fix would make it impossible to get Ulysses off this year.  Managers
hoping that just topping it off before launch will do; the leak is small.
[That's what they did.]

[That's it for AW&ST; not much news that week.]

[18 July Flight International]
ESA Council approves the Huygens Titan probe as part of the Cassini mission,
and starts work on Artemis and DRS comsat projects.  Artemis is a technology
test for mobile communications and intersatellite communications, partly as
a preliminary for the Data Relay Satellite system, Europe's equivalent of
TDRS to support Columbus and Hermes.  Artemis will go up in 1994, DRS in
1996 if full funding is authorized next year.  Prime contractor for both
is Selenia Spazio of Italy.

US government tentatively states that it would approve export licenses
for US-build satellites being launched on Zenits from Cape York, and for
United Technologies to participate in Cape York development.  [Don't
remember whether AW&ST reported this or not.]

[1 Aug F.I.]
NASA's B-52 to commence tests of the shuttle drag chute system, to be
installed in Endeavour and retrofitted to the earlier orbiters.

Japan's NASDA announces plans for an unmanned space tug, for delivering
supplies to the Japanese section of the space station and maneuvering
other satellites.  Test launch possible in 1995.

Martin Marietta design bureau, er oops excuse me I mean Martin Marietta Inc,
awarded DoD contract to redesign the payload adapter for Titan IV/Centaur.
The Titan IV/IUS launches flown so far have revealed much higher levels
of shock and vibration than expected.  IV/C launches will be delayed.

You left out the most unique thing about the X-29--the wings are swept
forward, not back like ordinary aircraft.

You're right, of course, about its not replacing the Shuttle.

Why yes.  Starts on pg. 1135 in my version.  I quote:

   "Notice that this system is only invariant under transformation
    by a *constant* phase, i.e., f(x) -> exp(ia)f(x).  What happens
    if we try a transformation of the form f(x) -> exp(ia(x))f(x)?
    ...and by combining our phase transformation with our gauge
    transformation, we find that our Lagrangian is unchanged.  We
    will, throughout the rest of the Koran, be referring to this new
    transformation when we use the words, *gauge transformation*...
    so we see that the existence of the photon is neccesitated by
    requiring gauge invariance and quantizing the resulting connection
    field.  We call such particles gauge bosons..."

In the original version, the word y'khlari was used in place of gauge,
mosfrit in place of boson, etc.

Why do you suppose Lacrosse looks red?  I assume they would not have
painted it (and if they did, would you paint it a light absorbing
color like red?).   Are there solar panels that might reflect that
color?  Interesting.  I must admit, in many years of satellite tracking,
I don't recall ever having seen a color associated with a satellite,
so this is intriguing (I also have faith in Beresford's observations).

Pretty bizarre to think we've come 20 years, with CAD/CAE and materials
engineering and we can't build something which was put together in the '60s.
Kinda scary.

* MARS VISIBILITY *
===================
The planet Mars will be visible to those living on the east coast of the
United States.  The planet will appear as a reddish "star" in the eastern
sky.  Best viewing will begin around 8:00PM local time.  Mars will be
closest to Earth on Tuesday, when it will be about 48 million miles from
Earth.  Viewing should be equally good through early December.


* SALYUT-7 NEWS *
=================
The presently unused and long abandoned Soviet space station 'Salyut-7' is
tumbling uncontrollably and is predicted to re-enter the Earth's atmosphere
in mid-January.  Attempts to boost the 60 metric ton structure to a higher
orbit have failed.  Salyut-7 should produce quite a spectacular light show
if it re-enters the atmosphere away from sunlight.

Here is element set 633 for Salyut-7 as released by NASA on 14-Nov-90:

* PACSAT NEWS *
===============
Work continues on UO-14 and AO-16.  DOVE-1 will be reset shortly after
software testing on the other Microsats is complete.


* RS-14/RUDAK-2 NEWS *
======================
Reliable sources within the Soviet Union indicate that the launch of RS-14/
RUDAK-2 is now expected to happen on or about November 24, 1990.  UA3CR
requests the help of radio amateurs all over the world to collect telemetry
and send it via packet radio or via a SSB net to him.  The first day's worth
of telemetry will transmitted via a CW beacon at 20 WPM on 145.822 or on
145.948 MHz SSB and will be vitally important to ground controllers.  Later,
after ALL systems are working properly on the RUDAK-2 transponder,
PSK/BBS/MODE B operations will begin.
