                            GALILEO STATUS REPORT
                              December 17, 1992

     The Galileo Spacecraft is operating normally in the dual-spin mode and
is transmitting coded telemetry at 7.68 Kbps (7680 bits/second).

     Yesterday, the Earth/Moon Conjuction movie was performed, as planned.
Also, the GOPEX experiment completed.  Real-time commands were sent to
turn the Plasma detector instrument off.  Continuous tracking was scheduled
over DSS-14 (Goldtstone 70 meter antenna), DSS-43 (Canberra 70 meter antenna)
and DSS-63 (Madrid 70 meter antenna).

     Today, December 17, 1992, the Earth/Moon Conjunction movie playback is
in progress.  Real-time commands are scheduled to disable the system fault
protection thruster firing all-clear response and to enable the Plasma detector
science alarm monitor.  Near continuous tracking is scheduled over DSS-14,
DSS-43 and DSS-63.

     Tomorrow, the playback of the Earth/Moon Conjunction movie will continue.
A routine RPM (Retro-Propulsion Module) thruster flushing maintainance activity
is also scheduled.  Continuous tracking is scheduled over DSS-14, DSS-43 and
DSS-63.

The Spacecraft continues to perform well in its Inner Cruise configuration
with downlink communications at 250 bps and uplink at 125 bps utilizing
the low gain antenna array.  Flight sequence C4 continues to clock out
through December 18.

The Electron Reflectometer and Payload Data Systems will be powered off
today.  Geotail measurement data taken by the Magnetometer/Electron
Reflectometer has been recorded on Digital Tape Recorders 1 and 3.  The
data recorded during Geotail measurement will be replayed during the C6
sequence in late January, after High Gain Antenna communications have
been established and higher playback data rates can be supported.

Over the course of last week, Standard Control Processor 1 experienced 3
Single-Event Upsets.  This is only slightly higher than the predicted rate
and is not considered a cause for concern by the spacecraft team.  The
Attitude, Articulation and Control Subsystem (AACS) experienced an unusually
large number of unidentified star transits during the transition to the new
star catalog for the second week in a row last week.  AACS engineers
believe the problem to be related to gyro scale factor growth during the
large star catalog/ephemeris-induced spacecraft attitude transitions in
preparation for transition to Outer Cruise configurations and operations.
Using this hypothesis, Spacecraft Team members have been successful in
replicating this phenomenon on the Verification Test Laboratory
spacecraft testbed and are planning command changes in the next star
catalog/ephemiris loads to insure that the spacecraft retains its internal
reference for star identification.

The Flight Software Version 7 Final Design Review is being held today at
JPL.

Today, the spacecraft is 27,169,270 km (16,882,201 miles) from Earth,
traveling at a velocity of 6.9548 kilometers per second (15,557 miles per
hour) with respect to Earth.  One way light time is approximately 91
seconds.

-     I would like to see the math that shows that TDRS could not be sent to
-Jupiter, remember that a TDRS has relatively large fuel tanks, in addition to
-fuel in the IUS.

I expect that the TDRS satellites have only very small rocket engines,
intended for slow maneuvering and stationkeeping. It might take a stronger
thrust over a shorter period of time to insert it into Jupiter orbit.

The impession I had was that there are several presidential airplanes,

Are you disputing that the modifications that must be made to the shuttle
to accomodate Centaur are non-trivial?  I.e., would *not* require a
major refit to an orbiter including special arrangements to handle venting? 

Sure, the EDO pallets are located in the cargo bay but they are permanent
plumbing, so to speak, that were added during another "major" refit and
modification.  And they certainly don't vent boil-off into the cargo bay.  But
I assume that the dewars which hold the EDO LH2 and LOX are better insulating 
than the tanks of a Centaur and therefore won't vent nearly as much during
the wait on the pad and during ascent (if at all)...
  
I suppose that once one is on orbit, and if Centaur is kept in the shade,
the boil-off problem diminishes rather rapidly thanks to the rather fine
insulating characteristics of vacuum.   

Can anyone point to a detailed description of the Shuttle-Centaur mods
that were proposed long ago?   I guess back issues of AW&ST would provide
some info.  What about conference proceedings from somewhere?

When I understood right the guy in Tucson at the air museum any aircraft of

So there might not be only one B707 and one or two B747's, but still more.

 Nope. Just about everything on that mission could have been divied up
 and flown on other Shuttles. The Space Vision System on any flight which
 has the RMS. No RMS scheduled? Add it to a mission and then add SVS.
 USMP? That's one pallet. LAGEOS was another. What was Columbia carrying
 in the rest of the payload bay? Room for two more pallets, at least.
 Put differently, LAGEOS and USMP-1 could have been flown on any mission
 with space for one pallet in the payload bay. That's most missions.
 Even the TDRS/IUS flights have room for one more pallet or good-sized
 payload. 51L had TDRS/IUS and the Spartan satellite in the payload bay,
 so the capabilty is there. The LBNP? That's a middeck experiment, suitable
 for just about any Shuttle mission. The crew was too busy? Okay, then
 fly the EDO pallet for the mission and spread the work out over four or
 five more days. This was Columbia, afterall.
 
 By the way, now NASA is planning to fly STS-62 carrying ONLY the USMP.
 At least, that's all that appears on the manifest for the mission posted
 here a couple of weeks ago. How on Earth is NASA going to justify THAT?

As part of the process of developing the Lunar Resources Data 
Purchase Act (the "back to the Moon" bill), it will be necessary to
explain, in the introduction of the Act, the rationale for
establishing an immediate national requirement for lunar science data.
Congresspersons generally don't like to throw away money outside
their own districts without a good reason, so we need to explain,
in a compelling manner, why we need to go back to the Moon in
the 1990's to obtain a complete chemical map.
 
Why can't we wait for this information until the year 2000, or 2010,
or beyond? Why is it in the national interest to send probes *now* 
back to the Moon?
 
If you can develop a convincing rationale for an immediate exploration
of the Moon by a lunar polar orbiter, please forward me the Reader's
Digest version - the winner of this informal  contest gets their
verbage in the Back to the Moon bill, which is to be introduced in
the 103rd Congress.
 
The Lunar Resources Data Purchase Act would authorize the U.S. 
government to purchase lunar science data from private vendors, 
selected on the basis of competitive bidding. For more information
on the Act, please send E-Mail, or call 714/524-1674.

In honor of the achievements of the Mariner 2 mission, we

the planned shutdown of the operational Magellan spacecraft

We have only made a limited number of interplanetary spacecraft
and thus it seems almost criminal to shut off a spacecraft

good, practical ideas in there.  I know that NASA did take a more friendly 
attitude to ET development a few years ago and the concepts even made it into
Business Week.  What happened?  Is development still chugging along somewhere
or is ET use to remain forever a dream?  Did the SOFI (Spray On Foam Insulation)
prove fatal to orbital use or did the normal economic and political hurdles
kill the companies that wanted to work on this?

[Note:  I thought about calling the post "ET Phone home" but figured that would
be both too corny and too confusing.  It would have fit the nature of the post
perfectly though.]

This may have been mentioned before but my site has a nasty habit
of trashing some articles.

If a DC-type spacecraft can make a vertical landing, would it be
capable of lunar flight? (with proper fuel and provisions for the crew
considered of course)

Also, how would a DC cockpit be configured?  I assume that the crew
would be seated on their backs during launch or landing, but would
that make landings tricky?

You mixture ratios are off.  The oxygen/hydrogen mixture ratio
in the SSME is 6; in the Saturn J-2, 5.5.  At a ratio of 6
this would be about 43 tons of hydrogen and 257 of oxygen.
About 20 trips.

However, the launcher would almost certainly have fuels piped to it
directly from remote storage tanks, as NASA currently does at the
shuttle pads.

Actually he was given a look at a B-2 model while it was still a black
program.  His reported words were "Now I know why I got to live so long".
