Subj: Mission Status Report #16
MISSION CONTROL CENTER
STS-61 Status Report #16
Thursday, December 9, 1993, 7 p.m. CST
With a successful space-walking work week over, the STS-61 crew is
scheduled to part company with the Hubble Space Telescope early
Friday.
Release is scheduled for 1:13 a.m. CST Friday (MET 7/21:46), but
Space Telescope Operations Control Center workers are investigating
some conflicting data relating to the operation of an HST data
interface unit that monitors telemetry from the telescope's
subsystems. In the meantime, shuttle flight controllers have
delayed a planned maneuver so that HST's solar arrays can remain
pointed at the Sun.
When the "go" for redeploy is given, the STOCC will prepare HST for
grapple by loading navigation tables into its computer, powering
down its solar arrays and powering up its reaction wheel assemblies
and magnetic torquers.
About 10 minutes later, Mission Specialist Claude Nicollier will
grapple the telescope with Endeavour's robot arm. Forty minutes
after that, the crew inside Endeavour will command the shuttle's
electrical umbilical to disconnect from HST, and open the berthing
latches holding HST on the cargo bay Flight Support System.
Nicollier will raise HST out of the payload bay into release
position.
Half an hour later, STOCC controllers will command HST's aperture
door to open, which is a 33-minute-long activity. Final release
preparations will take another half hour.
Immediately after Nicollier releases the robot arm's grapple
fixture, Commander Dick Covey and Pilot Ken Bowersox will fire
Endeavour's small maneuvering jets and move the shuttle slowly away
from the revitalized and reboosted orbiting observatory. Another
engine firing 20 minutes later will increase the rate of
separation.
Flight controllers awakened the crew at 5:57 p.m. CST Thursday for
Flight Day 9 with the song "Hard Day's Night," by The Beatles.
All systems on board the shuttle continue to perform well as
Endeavour circles the Earth every 96 minutes in a 321 by 320
nautical mile orbit.
