MISSION CONTROL STATUS 6
MISSION CONTROL STATUS REPORT #6
7:45 P.M. CDT SUNDAY, OCT. 7, 1990
MET 1/13:00
All is quiet onboard the Space Shuttle Discovery as the
STS-41 crew sleeps following a busy second day in space.
Discovery is performing very well, and there are no major
system problems.
During Flight Day Two, crew members worked with eight of the
nine secondary payloads. At about 9 a.m. the crew began the
check-out of the remote manipulator system and eventually
raised the payload bay arm up to position the Intelsat Solar
Array Coupon. Intelsat was launched in March of this year and
became stranded in low Earth orbit. Plans are in work now for
the rescue of the international communications satellite by
the space shuttle in 1992. Investigators hope the coupon on
Discovery, which will stay in its current position until
Tuesday, will indicate the condition of the materials on the
stranded satellite's solar arrays.
Mission specialists Bill Shepherd and Bruce Melnick also
worked with the Voice Control System. The VCS, designed to
manuever cameras using verbal commands, will be exercised
again Monday and Tuesday. In today's test, Shepherd had some
difficulties manuevering the camera, but Melnick was more
successful with his test.
The Solid Surface Combustion Experiment was performed
successfully as was the Investigation into Polymer
Membrane Processing. Results of those two experiments will be
analyzed after Discovery returns to Earth Wednesday.
On Monday the crew will work with the Radiation Monitoring
Equipment, the Physiological Systems Experiment and Chromex.
Additional data regarding the Earth's ozone layer also will
be collected as part of the Shuttle Solar Backscatter
Ultraviolet experiment.
Ulysses controllers at the Jet Propulsion Laboratory report
that the spacecraft deployed yesterday from Discovery is
performing very well. Today the radial boom was deployed. The
high gain antenna will be positioned Wednesday, followed by
the first trajectory correction manuever scheduled for Oct.
13.
Discovery is currently in a 160 by 154 nautical mile orbit.
