Help! I am trying to unsubscribe to this list. I tried sending
LISTSERV@UGA and LISTSERV@UBVM UNSUB SPACE commands, but both say I am
not subscribed to the SPACE list. I even sent an UNSUB SPACE (GLOBAL
command which should go to every listserv, but I am still receiving
these digests. I don't want to be on the list!!!

Subject: Re: Skylab


I recently went to the Museum at Esperence Western Australia.  In this
tin shed ( and 44 degree C in the shade) there are many colonial
exhibits: ploughs, carts, lace work, and some of the remains of SkyLab!!!

Various bits and pieces are there: scorched electronics, a safe, broken
tanks.   But the best exhibit is a perfectly spherical tank about 80cm
diameter (< 3ft), showing not a dent or scratch (just a few scorch marks).
It is sitting on the floor of the old train shed, with a small hand written
sign on it saying "DONT TOUCH"!!!!   This thing survived reentry undamaged
and they are worried about a few finger!!!! (Somebody did touch it, a
teenager tried to roll it -> but he could not even shift it an inch!)

The description of the tank is "water tank".  If this is true it was
MASSIVELY over engineered.  Looking at the model they had there I think it
is more likely to be one of the Nitrogen tanks around the end of the
main cylindrical section.

Subject: Frequently asked SPACE questions

This list does change.

This is a list of frequently asked questions on SPACE (which goes back
before 1980).  It is in development.  Good summaries will be accepted
in place of the answers given here.  The point of this is to circulate
existing information, and avoid rehashing old answers.  Better to
build on top than start again.  Nothing more depressing than rehashing
old topics for the 100th time.  References are provided because they
give more complete information than any short generalization.

Questions fall into three basic types:
1) Where do I find some information about space?
Try you local public library first.  You do know how to use a library, don't
you?  Can't tell these days.  The net is not a good place to ask for
general information.  Ask individuals if you must.  There are other sources,
use them, too.  The net is a place for open ended discussion.

2) I have an idea which would improve space flight?
Hope you aren't surprised but 9,999 out of 10,000 have usually been
thought of before.  Again, contact a direct individual source for
evaluation.  NASA fields thousands of these each day.

3) Miscellanous queries.  Sorry, have to take them case by case.

Initially, this message will be automatically posted once per month
and hopefully, we can cut it back to quarterly.  In time questions and
good answers will be added (and maybe removed, nah).

1) What happen to Saturn V plans? What about reviving the Saturn V
as a heavy-lift launcher?

Possible but very expensive -- tools, subcontractors, plans, facilities
are gone or converted for the shuttle, and would need rebuilding,
re-testing, or even total redesign.

2) Where can I learn about space computers: shuttle, programming,
core memories?

Subject: Re: Galileo Update - 04/10/90

I'm curious about something w/r/t Gravity Assist maneuvers.  Are the
positions and gravitational influences of the satellites taken into
account?  In this case, do the Galileo calculations include Lunar
effects?  Do they really check to make sure it won't smack into the
moon?

Also, do mascons matter?  Or the exoatmosphere?

I'm just asking, someone on the net probably does three of these
calculation sets before breakfast. :-)

NASA Select TV is NASA's satellite feed of internal NASA video images.  Most
shuttle related video (launch, landing, and orbit) are broadcast on NASA
Select, as are other launches and missions.  Specific dates and times may be
obtained from the daily NASA Headline News that I post.  The frequency of
broadcasts is directly related to the number of ongoing missions.

Subject: Challenger Centers

In response to recent postings about the Challenger Centers, I am
posting this information which I received from the center:


Challenger Center for Space Science Education
1101 King Street, Suite 190
Alexandria, VA  22314
[phone]

Mission Statement:  The Challenger Cener strives, through innovatinve
teaching and learning experiences, to inspire and prepare our nation's
youth for the technological demands of the future.

Challenger Center is the manifestation of a vision held by the families
of the shuttle Challenger astronauts--that the educational mission their
loved ones valued so highly would continue, that it would serve the
nation as they did.  That mission is to teach and to inspire our
youngsters to pursue paths of discovery and to explore new frontiers.

Challenger Center designs state-of-the-art programs to help invigorate
the interactive learning process between teachers and students and to
increase the effectiveness of technology-oriented education for a world
increasingly dependent on those students.

Challenger Center emphasizes teh pursuit of individual excellence eithin
a cooperative team environment; its programs provide approaches to
problem so9lving that will stay with children into their adult life.

Challenger Center aims to reach as many students as possible--at an age
when they are most receptive.  The Center reaches them physically,
through its grassroots programs, and emotionally, by using the human
fascination with space as a way to spark their interest.

What Does Challenger Center Do?

Inspire grade school students through various educational programs
targeted directly at students and at teachers.  Over 400,000 students
and 5,000 teachers will benifit from Challenger Center programs during
1990.

Conduct regional teacher workshops and conferences across teh country to
provide teachers with stimulating tools and methods that will energize
the learning process.  Over 100 workshops are scheduled during 1990.

Manage a network of hands-on educational facilities called Learning
Sites, where children learn about math, science, technology,
communications, teamwork and problem solving through realistic space
flight simulations.  Three are in operation with seven more due to open
in 1990.

Assist outstanding teachers through an annual fellowship program,
helping them initiate innovative projects, sending a signal to educators
that their work makes a difference.

Conduct educational classroom teleconferences that operate on a
grassroots level to allow children across the country to participate in
exciting, high-technology learning activities.  The January 26, 1990
broadcast reacfhed over 175,000 children in more than 900 schools.



    Once again, this comes directly from a letter from the Challenger
Center.  Disclaimer:  I don not represent the Challenger Center in any
capacity, and ant typographical errors in this posting are mine.  I
simply feel that more people should know about the Centers.  We all know
that the quality of math and science education in this country has been
declining, and the Challenger Centers are fighting this decline.  I
certainly wish something like this was around while I was in school.  I
hope this has inspired some of you out there to seek more information.
Contributions may be sent to the address listed at the beginning of this
post.

  My recollections of attempts to do a test launch from an operational silo
were that they were all quashed due to the prospect of the multi-ton first
stage coming down somewhere in the U.S. , possibly on the head of some
tax-paying (and probably litigating) citizen.  I was involved in the other leg
of the triad and we did regular test launches from operational silos
(submarine missile launch tubes) which worked reliably a large percentage of
the time.

Subject: Voyager/Neptune images request.


I am interrested in obtaining the images from the Voyager Neptune flyby from
last summer. Could somebody please let me know how I go about obtaining these?
Also, does anybody know the format of the data files? I have a 386 AT with a
VGA card and am wondering what sort of viewer I will need to write.

    Thanks in advance.

Subject: Early Release of HST Images (Forwarded)

THE WASHINGTON POST -- APRIL 10

"EARLY RELEASE OF TELESCOPE DATA SET"  By Kathy Sawyer

"NASA Officials said today they will release raw 'engineering'
images from the pioneering Hubble Space Telescope a few days
after it is launched rather than keeping with the original plan
of waiting two weeks or more for electronically processed
'pretties.'"

The decision, the POST reports, came as the countdown
was proceeding smoothly toward a Tuesday morning launch and
apparently under pressure from news organizations.

NASA's Charles Pellerin declared that images from a focus test
performed on the fourth day of flight will be shown in black and
white at NASA's Goddard Space Flight Center, Though he termed
them "engineering pictures.  Pellerin emphasized.  'We  didn't
want to hype this as the first picture because it isn't a scien-
tific picture,'" and may include blemishes, the POST
reported.

"True 'first light' pictures, thoroughly processed and indicative
of what the telescope will be capable of, are to be released
about two weeks after launch by NASA Administrator Richard H.
Truly."
