[e-mail] (Rich Kulawiec) says, in part:


This is ludicrous.  If you do not have the courage of your own convictions,
and are not willing to back those convictions up by using your own name,
why should anyone pay the slightest attention to you?  (I certainly won't)
Either you have the guts to back up what you say, or you don't; and if you
don't, then you should probably just be quiet.

Right.  So -- Anne Frank should have kept her kvetching trap shut, right,
right, Mr. Kulawiec?

I take great offense at the (fill in nasty characterization here) comparison
of an anonymous post of (fill in objections to post here) material with Anne
Frank under danger of death from the Nazis.

Anyone who would make such a comparison is a (fill in...no, I'll say it) a
moral defective.

Anne Frank did keep "her kvetching trap shut"; her diary was published
posthumously.  Not that there is any point of comparison between Anne
Frank and some rumor-spreading weenie on the Net.  Idiot.

I would argue that step 5, is permanent presence.



And then if So,  NASA should maintain  an orientation to an effective
manned space program.

Planetary science  really should be an NAS/NSF domain,   NASA should be
an engineering test/ build program.

Flyby is  important for first look,  but orbiters/landers are needed
for  in-situ science.   Somehow even if we get cheap/fast propulsion
I can't imagine  manned missions to Uranus.

Until we make some real big breakthroughs,  we are stuck  here in
Earth/Moon/ Mars/ ASteroid  space.

I can't see much point in manned missions to  Mercury, venus, jupiter. et al.
Not unless we have a big space faring economy.

The romans  built a massive empire  on square rigged sail.  The mongols
built their empire  without boats (llok what happened when they tried water).

But the British built a massive empire  based on mercantilism  and
Lateen sails.

We right now a land based society trying to explore with primitive
row-boats.  What we need is better boats   and reasons to go to sea.

Mandarin china built enormous fleets and burned them because their
society had no reason to go to sea.  Look where they ended up.

We should look at exploring the outer planets  because they are there, but they
should be funded  as on-going  projects.   NMT  2 billion/year
DDTE, OM and AR&D.   let the space science community then
prioritize on  orbiting telescopes (HST/SIRTF)  against  Orbiters
(Magellan/Cassini)  and  Landers (Cassinni, MESUR, CRAF)

Meanwhile  we should be looking at building the infra-structure for going
to space  to amke money.   I believe we should be there because we can
be there,  but we can't break the bank trying to fly to the stars.

We need to fund about 4-6 Billion a year on manned space,  but on
practical manned space.  DDTE  for a space station.  AR&D on life
support and work suits.  O&M  for lunar bases  and industrial
facilities.   Mission planning and support for ASteroid exploitation.
Permanent Mars Science station.  advanced propulsion.

Right Now NASA gets about 14 billion/year.   4 billion goes to shuttle.
2  goes to SSF.  3 billion goes to planetary and space science.
About 1 goes to Aero.  The remainig 4 goes to OH, G&A,.....

Right now,  we could transfer funds out of manned space ops  and into

the technologies that give us a win down the road, or we can stay
stuck at where we are.   Funding levels are adequate,  they are merely
mis-directed.

perhaps teh re-review of SSF will provide for a change in direction.

Subject: Galileo Earth-Moon Animation
Newsgroups: sci.space,sci.astro,alt.sci.planetary

                       ==============================
                        GALILEO EARTH-MOON ANIMATION
                               March 7, 1993
                       ==============================

     The Galileo Earth-Moon Conjunction animation is now available in
additional formats at the Ames Space Archives.  The animation was formed from
46 images taken by Galileo spaecraft shortly after its Earth flyby on
December 16, 1992.  The new formats are FLC and Quicktime.
The Quicktime version only needs 1MB of RAM to run.  The animation
is available using anonymous ftp to:

        ftp:      ames.arc.nasa.gov (128.102.18.3)
        user:     anonymous
        cd:       pub/SPACE/ANIMATION
        files:
                  emconj.flc        - Earth-Moon animation in FLC format
                  emconj.txt        - Caption file (see below)
                  Earth_Moon_qt.hqx - Earth-Moon animation, Quicktime format
                                      (Binhexed)
                  Earth_Moon_qt.cpt - Earth_Moon animation, Quicktime format
                                      (MacBinary)

     Software to run the FLC version is also available at Ames.  Play79
is used for the IBM PC, and a special version of the xanim program was
created to run the animation which runs under X-Windows on Unix.

        ftp:      ames.arc.nasa.gov (128.102.18.3)
        user:     anonymous
        cd:       pub/SPACE/SOFTWARE
        files:
                  play79.zip   - IBM PC
                  xanim.Z      - Unix
                  xanim.readme -
--------------------------------------------------------------------------
emconj.txt

Emconj.flc is in Autodesk Animator .fli format for MSDOS PCs and the X
windowing system. The file can be viewed using the play79 program for
MSDOS (available in the pub/SPACE/SOFTWARE directory on
ames.arc.nasa.gov) or the freely available xanim package for X.

This is part of a time-lapse sequence taken by the Galileo spacecraft on
December 16, 1992, eight days after its flyby of the Earth/Moon system
en route to Jupiter. The full color sequence utilized the 0.968, 0.727 and
violet filters; this reduced, black-and-white version was made with the 0.968
micron filter so that both vegetated and unvegetated land masses appear bright
in contrast to the oceans. The 46 frames span 15 hours of motion by the Earth,
Moon and spacecraft as viewed from the perspective of Galileo, with South at
the top. Visible are the Pacific basin, Australia, Southeast Asia, India, and
finally Arabia and the horn of Africa. A remarkable feature of this sequence
is the specular reflection or sun glint from the sea surface. Depending on the
roughness of the water the extent of specular reflection varies rapidly,
expanding over rough seas and contracting to a point over still oceanic pools
such as near the west coast of Australia.

This I realy had not heard before. I thought that so far moon littering was
confined to the immediate surroundings of the landing sites (Apollo, Luna
etc). Just how many man made objects are up there by now? Naturaly I'm talking
about Soviet-made ones too.

                       ================================
                        MAGELLAN VENUS GLOBE ANIMATION
                                March 7, 1993
                       ================================

     The Magellan Venus Globe animation is now available in additional
formats at the Ames Space Archives.  The animation consists of 72 frames
derived from the Magellan CD-ROMs.  A QuickTime version of the animation has
been created.  For those who have monochrome (black and white) Macintoshes
like the Mac Plus, SE, Classic, and so forth, a dithered version was created.
It is a PICS "stack" and works with the "PICS Player" module of After Dark.

The animation is available using anonymous ftp to:

        ftp:      ames.arc.nasa.gov (128.102.18.3)
