Randy,

I have been trying to find a gateway between Internet or Bitnet
to Telenet or Tymnet.  So far I have had no luck.  Telenet said
one doesn't exist; Tymnet was working on it but from Tymnet to
Internet only.

If you get any info about the Telene gateway, I'd appreciate a
copy.  Thanks.

Steve

P.S.  There is a Randy Miller who is a DJ in Kansas City.  Pretty
      wild show.  Any relation?

                     GALILEO MISSION STATUS
                           May 3, 1990

     The Galileo spacecraft is about 94 million miles from Earth,
and 89.3 million miles from the Sun.  It is travelling around the
Sun at a speed of almost 69,000 mph, and it has gone almost 391
million miles since launch.

     The spacecraft health continues to be excellent.  Current
activities include routine Sun-pointing about every other day,
and other housekeeping tasks.  Science activities include
measurements of the interplanetary environment by the
magnetometer, dust detector, and ultraviolet instruments, which
are stored in a computer memory and read out to the Earth about
twice a week.

     The Galileo flight team is preparing for the next
trajectory correction maneuver, scheduled for Friday and
Saturday, May 11-12.

ASSOCIATED PRESS, MAY 3, 1990

"HUBBLE TELESCOPE"
By Harry F. Rosenthal

"An error by a ground controller put the Hubble Space
Telescope to sleep again overnight but the $1.5 billion
instrument was re-awakened Wednesday and was
functioning normally again."

The telescope went into a "safe-mode" when the 10-
foot diameter aperture cover closed and its motion
triggered the shut-down.  Ground controllers failed to
tell the telescope not to close its protective cover
during a test, the AP reported.

NASA said the spacecraft operated just as it should
for 72 hours without ground control and it has
now functioned three times:  When the door was first
opened, when an errant cable caused resistance to one
of the the high-gain antenna's movements and the
during the latest test.

While 10 hours in the lengthy start up process were
lost, no delay was expected in getting the first pictures
from the telescope early Saturday.   The AP reported
NASA saying that "problems of that nature are ex-
pected during a start-up process that will take more
than six months before the first real scientific re-
turns."

Subject: address for "Plymouth" letters

A posting on 1 May (item 2174) mentioned the ABC TV-film project "Plymouth" and
called for letters of support.  For those of you interested in this story about
a new town on the moon (which could become a weekly series if enough interest
is expressed) here is the mailing address for comments.

Subject: The PIONEER Plaque and VOYAGER Record


    >> "Do you think, that they will think, his arm is permanently
    >> attached in this position?" --- Laurie Anderson (about the picture on
    >>                          the golden disc aboard the Voyagers)

        I believe Ms. Anderson was referring to the depiction of the
    male human on the PIONEER 10 and 11 plaque.  The "golden disc" on
    VOYAGER 1 and 2 (which houses the Interstellar Record) has no such
    engraving on it.

        On the PIONEER plaque, there is a representative nude male and
    female human drawn in front of a schematic of the PIONEER probe (to
    help indicate our size in relation to the craft).  The man is exten-
    ding his right arm upward in what will hopefully be interpreted by
    whomever finds the spacecraft as a friendly salutation.  The woman
    is standing next to him with both of her arms down.  The plaque's
    designers did not want both people to raise there arms, lest the
    beings who find it (presumably non-human) think that all humans
    have their right arms in that position.

        In one of the images on the VOYAGER record, though, there is a
    reproduction of the nude man and woman from the PIONEER plaque, but
    this time it is the woman who is raising her arm in greeting and the
    man who is "merely" standing there.

        PIONEER 10 was launched to Jupiter in 1972.  PIONEER 11 was
    launched to Jupiter and Saturn in 1973.  VOYAGER 1 and 2 were
    launched to study Jupiter, Saturn, Uranus, and Neptune in 1977.

Subject: Re: Fermi paradox

Recent posts have put forward various unknown probabilities, whose
product is the probability of life somewhere/anywhere.

However, the list of unknowns was fairly old. I believe that
planetary science has moved on, and the list must now be longer. For
example:

Bombardment: Earth gets occasional hits from major solid objects.
This can have a major effect on evolution - both by destruction, and
by allowing minority creatures (mammals?) to move into previously
filled niches. What would be the effect of more bombardment, or of
less?  Gee, good question.

Magnetic field: This shields us from a lot of solar radiation.  Is
the Earth's field unusual? Who knows? It seems to have a connection
with:

Continental Drift: This is important because it recycles the ocean
floor.  Neither Mars nor Venus have continental drift, so we can't
blithely assume that it's common on rocky planets.

Solar stability: Perhaps Sol is unusually quiet. If its output were
to grow or to shrink by various percentage points, then the Earth's
biosphere-as-we-know-it would collapse. So, long-term stability is
important.  And what about major flares?

Hello,
  Does anyone have any information on the United States Space Camp
in Alabama and/or Florida?  My SO and I were considering going, but
we didn't want to get mixed into something that is "just for kids".

  We are both technoweenies, she working for Lockheed Missiles and
Space, and I with an avid interest in aerospace and space (but working
for a telecomm company, natch) and we'd hate to spend that much money
to be taught stuff that's aimed at kids.

  Any comments, or suggestions as to alternate sources of this kind of
experience?  Please email, or post to this group if it bounces...

  Thanks!

    Okay, wait a minnit..... you know about the inferno?
    You know that its the hottest terrestrial planet?
    Do you know that the longest any UNMANNED craft has
    survived is a few hours?

    The Russians have been sending their Venera landers
    there for years.  The best they've been able to do
    is 46 hours with Venera 16 (Vega 2) in 1985.

    What makes you think that we could withstand the 460C
    temperatures that machines could not?

>- The athmosphere of Venus has the same quantity of oxygen as here.

    It's not the oxygen.  Venus's atmosphere is composed
    of 3.5% Nitrogen, as opposed to Earth's 80%.
    What little oxygen there is shares the same 5% of
    Venus's atmosphere as the sulfuric & hydrochloric
    acid present.  And, lest we forget, 96% CO2!
    If that wasn't enough, recall that the clouds
    on Venus are made up largely of sulphuric acid.

    Of course, if you *do* find someone to build
    you a suit to withstand that, it will have to
    withstand an atmospheric pressure 90 times
    that of Earth.

    If you find one of those, it might be wiser to
    sell it to alt.flamers......

I think that you've got a point. What is the feasiblity and possibility of
working a shuttle rendezvous to pick up a satellite which has been
in orbit for quite a while? Maybe there are a couple of old Big Birds which
would be nice to deorbit?

ALSO, what would be be possibility of "flying back" an old space probe
into LEO, rather than letting them drift around for years and years. You'd
need some propellant leftover and some communications capabilities to
tell it what to do, but I'm amazed as to what one can do with a couple
of large planets for assistance....
