When Galileo does it's Earth fly-by on 8 December, will the Shuttle be
able to see it? I'm assuming the Shuttle will be up on that day, but
if it isn't, don't flame me, OK? Thanx! (-:

Astro 1 Mission Report #30
08:15 a.m. CST, December 7, 1990
5/07:25 MET
Spacelab Mission Operations Control
Marshall Space Flight Center
"This is the proudest moment of the mission to date!" exclaimed
Astro Assistant Mission Manager Stu Clifton as he came out of a
shift briefing. "Following the loss of the Data Display System,
Astro has recovered substantially in less than 22 hours. All
experiments are recording excellent data."
At approximately 5:35 a.m. CST, all three ultraviolet instruments
got scientific data on a target known by astronomers as Q1821. This
radio-quiet quasar is one of the most luminous objects in the
universe, brighter than many galaxies combined.
According to HUT Assistant Project Scientist Gerard Kriss: "It is
thought that Q1821's enormous radiation emission is powered by
matter falling into a black hole in its center -- an area more than
a hundred million times the mass of the Sun. Gas stripped from
nearby stars in the host galaxy of this quasar should get hot as it
falls into the black hole, forming a swirling disk, much like water
draining down a sink. Astro scientists are looking for the
characteristic radiation that would be emitted by this hot gas.
This would provide some of the first hard evidence for the existence
of such super-massive black holes."
When asked to comment about the status of the mission, Project
Scientist Geoff Clayton eagerly replied: "I am really happy that we
are back observing! Twelve hours ago we weren't really sure what
was going to happen. But we got back to observing much faster than
we thought we were going to, and we really feel like it's all gravy
now. We are observing most of the time now, and we're doing a much
simpler operation that will get better and better as we continue
observing in this mode."

This is NASA Headline News for Friday, December 7, 1990
The Space Classroom became a reality today, as the Astro-1 science crew
conducted lessons from space this morning. The lesson, entitled
"Assignment: The Stars", is part of a NASA effort to bring the
excitement of real space science to students and teachers and to
encourage interest in mathematics, science and technology.
Astronauts Samuel T. Durrance and Jeffrey A. Hoffman, conducted the
lesson from orbit which focused on the invisible and the visible
universe -- the electromagnetic spectrum and how Astro-1 extends our
vision of the many kinds of celestial bodies and events. Astronauts
Ronald Parise and Robert Parker joined in the second session, the
question and answer period of the program. Students and teachers in
classrooms at Marshall and Goddard Space Flight Centers received a
ground-based lesson from teacher Karen Widenhofer from Marshall
following the initial session from Columbia.
Back in business, the Astro-1 observatory aboard the Space Shuttle
Columbia resumed its astronomical activities last night, following the
loss of a computer terminal yesterday. The efforts of the Columbia
crew and ground teams at Marshall and Johnson Space Flight Centers
transformed what look like a dismal situation for the Astro-1 mission,
into near routine science gathering. A procedure for commanding the
three ultraviolet telescopes, and taking observations which integrate
operations at JSC, MSFC and aboard Columbia, came together more quickly
than anticipated, and a "good lock" was made on Supernova 1987A shortly
before 6:00 pm yesterday.
The team worked through the night to refine the operation, and in the
early morning hours today, a radio-quiet quasar, Q1821, was targeted
and observed in minimum time. Prime telescope for observations last
night was the Ultraviolet Imaging Telescope, which observed NGC 1633.
After solving earlier alignment problems, the Broad Band X-ray
telescope came on line to make two observations of NGC 1399 in the
constellation Fornax, Q1821+64, and Abell 2256, a spiral-poor galaxy
cluster.
Gaining a gravitational boost on its six-year journey to Jupiter, the
Galileo spacecraft will zip by Earth tomorrow, some 680 miles from its
surface. It will reach its closest approach at about 3:35 Eastern
time. Galileo's next fly-by of Earth is in early December, 1992, the
last gravity assist required to hurl it to Jupiter. Following
tomorrow's fly-by, Galileo will pass within 600 miles of the asteroid
Gaspra in the autumn of 1991.

Subject: galileo & the shuttle
Well, now that we've got the shuttle up there, and the
Galileo spacecraft speeing toward Earth, what's the
chances that the shuttle personnel will be able to
directly view the Galileo and/or get some pix of its
approach? Also, aren't there some personnel in Mir at
this time? What are their chances of viewing the Galileo?
