MISSION CONTROL STATUS REPORT
Report #2
Oct. 6, 1990
MET 00/15:45
CDT 10:30 p.m.
Following a successful deploy of the Ulysses spacecraft,
flight controllers are busy finalizing plans and preparing
messages for the second day of STS-41.
Ulysses was successfully deployed from Discovery's payload
bay about six hours after launch. The two Inertial Upper
Stage motors and the single Payload Assist Module then
started the spacecraft on its five-year journey to the sun.
The PAM burn accelerated Ulysses to a speed of more than
34,000 mph, the fastest a vehicle has left Earth orbit. By
using a gravity assist of Jupiter to fling Ulysses out of
the orbital plane, the spacecraft will travel through a
previously unexplored area of space.
The STS-41 crew currently has slightly more than three hours
remaining in its eight-hour sleep period with the
wakeup call scheduled for 1:47 a.m. CDT. The five-man crew
will have a busy day working with eight
of the nine secondary payloads. Secondary payload activities
include work with Chromex, Investigations into Polymer
Membrane Processing, the Voice Control System, the Solid
Surface Combustion Experiment and the Physiological Systems
Experiment. The crew also will activate and take the first
data takes with the Shuttle Solar Backscatter Ultraviolet
instrument, and will position the Remote Manipulator System
Arm to collect data with the IntelSat Solar Array Coupon.
During the sleep period flight controllers enjoyed numerous
Earth views from the four payload bay and two remote
manipulator system cameras. Controllers also took the
opportunity to inspect the payload bay and orbiter's wings as
the cameras were being exercised.
Discovery currently is in a 178 x 160 nautical mile orbit.
