STS-80 Day 5 Highlights
Back to STS-80 Flight Day 04 Highlights:
- On Saturday, November 23, 1996, 6:00 a.m. CST, STS-80 MCC Status Report # 9
- With both of their free-flying satellites deployed, Columbia's
astronauts today will focus on maintaining formation and working with
in-cabin microgravity experiments.
- Following a successful NC7 maneuver overnight, Columbia is 70 miles in
front of the ORFEUS-SPAS ultraviolet telescope and pulling away by
about 4 miles each orbit. The Shuttle is 18 miles ahead of the Wake
Shield Facility and separating by 1.5 miles each revolution. The
saucer-shaped satellite is about 53 miles ahead of ORFEUS-SPAS and the
two are moving 1 mile closer to each other each time they orbit the
- Overnight, the Shuttle's payload bay cameras provided television
pictures of the two satellites trailing Columbia.
- The Orbiting and Retrievable Far and Extreme Ultraviolet
Spectrometer, riding its Shuttle Pallet Satellite, continues to make
observations of stars and galaxies. Wake Shield science operations are
to begin about 8 a.m. CST today. Scientists from the University of
Houston's Space Vacuum Epitaxy Center spent the night preparing
their spacecraft for its first STS-80 foray into thin film
- Commander Ken Cockrell, Pilot Kent Rominger and Mission Specialists
Tammy Jernigan, Tom Jones and Story Musgrave are scheduled to awaken
at 11:56 a.m. CST. Cockrell and Rominger will kick off the next
maneuver to maintain the proper distance from its deployed payloads
about 2:30 p.m.
- Later in the day, Jernigan and Rominger will work with the
Visualization in an Experimental Water Capillary Pumped Loop
(VIEW-CAPL) experiment, Musgrave will be interviewed by CBS News (at
5:41 p.m. CST) and Cockrell will check on the rodents being used to
study the role of calcium in blood pressure regulation.
- Columbia and its satellites continue to orbit the earth at an
altitude of 220 miles.
- On Saturday, November 23, 1996, 6:00 p.m. CST, STS-80 MCC Status Report # 10
- Columbia continued to fly in orbital formation with two science
satellites Saturday as the crew turned its attention toward secondary
experiments inside the cabin.
- The shuttle now leads the Wake Shield Facility (WSF) spacecraft by
about 27 miles and the ORFEUS-SPAS by about 68 miles. Commander Ken
Cockrell fired Columbia's steering jets briefly this afternoon to
maintain the distance between the orbiter and the two satellites, and
another such engine firing may be required around 1:30 a.m. Sunday.
- Ground controllers for the Wake Shield have begun growing thin films
on the back side, or wake side of the satellite. The first growth
began at 6:37 Saturday evening. The film growths are of advanced thin
film semiconductor material using the prototype factory satellite.
The film growths will continue throughout the next several days while
the Wake Shield flies free of Columbia. It is scheduled to be
retrieved and placed back in the payload bay late Monday night.
- Aboard the shuttle, Payload Commander Tammy Jernigan watched over
operations with the VIEW-CPL experiment, a study designed by students
at the University of Maryland. The experiment tests capillary pumped
loop technology that one day may be used for more reliable spacecraft
cooling systems. Also Saturday, Astronaut Story Musgrave took time
out from his work with Wake Shield for an interview with CBS News.
- The other satellite flying free from Columbia since launch day, the
ORFEUS-SPAS, continues science operations using three different
instruments -- the Interstellar Medium Absorption Profile Spectrograph
or IMAPS, the Extreme Ultraviolet Spectrograph or EUV, and the Far
Ultraviolet Spectrograph FUV. Science observations by the three
instruments has now totaled more than 100 since the spacecraft was
deployed on launch day. ORFEUS-SPAS is scheduled to be retrieved on
Dec. 3 and returned to Earth aboard Columbia.
- The crew will begin a sleep period at 4:56 a.m. CST Sunday and awaken
for Day 6 of STS-80 at 12:56 p.m. Sunday. Columbia is in excellent
condition in a 220 by 215 statute mile orbit.
