1.)    It depends.
2.)    Most of its volume would be tankage and the crew's
    pressurized volume.  You would not be able to make
    a very big one fit in the Shuttle cargo bay.
3.)    Probably not.  Among other things, the Shuttle is not
    safe to use for transporting liquid fuels, so loads
    of fuel must go up on expendables.  The lunar shuttle
    might as well go up on one too, which then frees it
    from many Shuttle limitations on size.

That would be a design criterion, hinging on the results of
a feasibility and cost analysis.  I'm not going to draw
blueprints for the machine to go to the moon.  My only
purpose was to demonstrate that sending a Shuttle orbiter
to the moon is like trying to race a garbage truck in the
Indy 500; it's designed for a specific purpose, and won't
do very well when asked to serve a radically different one.
Even a simple analysis shows greater potential elsewhere.

                    PIONEER 11 STATUS REPORT
                      December 18, 1990

     On November 8, several commands failed to execute on the Pioneer 11
spacecraft, including receiver switch commands.  The USC/UV off command,
and the ARC/PA configuration commands also were not executed.  In an attempt
to evaluate these intermittent command failures, several benign status change
commends are included in the command sequences.  The lack of tracks one
roundtrip time after commanding, makes a determination of the success or
failure of the commands difficult.  Superior Conjunction will occur today.
The minimum Earth Probe Sun angle will be 0.47 degrees.

  I know this question probably keeps on poping up, but I keep on
  missing the discussion on .

  So if somebody could let me know if there are any space GIF images
  available for FTP, it would help me out a lot.  I would like to know
  location, etc, etc...

  Thanks for the help!

HST INVESTIGATION BOARD -- STATUS REPORT #1
July 6, 1990

The Hubble Space Telescope (HST) Optical Systems Board of Investigation met
for the first time July 5-6 in Washington, D.C.

Testimony was given by officials of NASA's Marshall Space Flight Center
(MSFC) and Hughes Danbury Optical Systems.

The MSFC personnel summarized the current status of HST systems and Hughes
Danbury representatives gave an overview of the manufacture and test
procedures for the HST primary and secondary mirrors and the Optical
Telescope Assemby (OTA). The presentations were general in nature due to
the impoundment of original pertinent data under the provisions of the HST
Contingency Plan.

The next meeting of the board is tentatively scheduled for July 25-26 at
Hughes in Danbury, CT. In the next two weeks activities will be carried out
in three areas:

* examination and analysis of pertinent data.

* preliminary interviews of knowledgeble individuals, and

* design and preparation of appropriate tests.

The board has modified the impoundment procedures sufficiently to permit
the activites above to begin while taking active steps, including
independent supervision, to ensure the integrity of the pertinent data and
hardware.

At the conclusion of the meeting, Chairman Lew Allen said, "The board now
has a good base of information from which to proceed with its
investigation."

In 1990 the Princeton Planetary Society published the first edition of
"Space Jobs:  The Guide to Careers in Space-Related Fields."  The publication
was enormously successful:  we distributed 2000 copies to space enthusiasts
across the country and even sent a few to people in Great Britain, Australia,
and Ecuador.  Due to the tremendous response to the first edition, PPS has
published an expanded, up-to-date second edition of the guide.

The 40-page publication boasts 69 listings for usmmer and full-time job
opportunities as well as graduate school programs.  The second edition
of "Space Jobs" features strategies for entering the space field and
describes positions at consulting and engineering firms, NASA, and non-profit
organizations.  The expanded special section on graduate schools highlights
a myriad of programs ranging from space manufacturing to space policy.
Additional sections include tips on becoming an astronaut and listings
of NASA Space Grant Fellowships and Consortia, as well as NASA Centers for
the Commercial Development of Space.

  The 'press agency' is calling it a hoax ? Oh great...now our news agencies
  are calling theirs to find out what's going on. I can see it now...

  "Good day Mr. Gumbel. This is Alexander Strobinslovac from the Soviet news
  agency Tass. I was wondering if either you or Ms. Norville would care
  to comment on the recent move by the Fed to lower interest rates. No ?
  What's that ? Mr. Scott will be briefing the press later this morning ?"

  If there's one thing I've learned in the last few years--and there is, I
  assure you--it's that second hand news reports are iffy at best.

  I'm keeping an open mind on this thing until I hear someone with some
  credibility comment on the situation. Once I hear a rock solid report
  from a more credible source than the local evening news or Good Morning
  America, then I'll start sending in my 3x5 cards.

  Yes, that's right, you guessed it...I'm waiting for the full up-to-date
  official word from where else--Aviation Week.

  Of course Space News has to confirm the story, you understand.

  But seriously folks...why is everyone so cynical ? Isn't this just what a
  whole lot of folks here on the net have been suggesting/hoping for/waiting
  for ? Why is this any harder to believe than the fact that the Japanese
  would send up a chain smoking, space sickness prone television reporter
  for $12 million ?

Okay, sounds reasonable.  Once you get the detector out into vacuum, you
bake it to outgas all the contaminants.  But HST has been up there for
a while, using these CCDs to take images of Saturn and lots of other things.
Why now - after x months - do you thermal-cycle them again?  Presumably it
was done when they were first activated in vacuum, if I understood your
explanation.  Do "deeper" contaminants migrate to the surface over time?
Ron's original posting said "contaminants which may have COLLECTED there
while the power was turned off" (my emphasis - the implication to me was
an external source of contamination).  And what does the power have to do
with this?  Sorry if these are silly questions. I'm just curious.
