STS-82 Day 1 Highlights
Return to STS-82 Mission Summary
- On Tuesday, February 11, 1997, 4:00 a.m. CST, STS-82 MCC Status Report # 1
- Right on time, Discovery and its seven astronauts lifted off from the
Kennedy Space Center to begin their chase to rendezvous with and
retrieve the Hubble Space Telescope for its second on-orbit servicing.
- Commander Ken Bowersox, Pilot Scott Horowitz and Mission Specialists
Joe Tanner, Steve Hawley, Greg Harbaugh, Mark Lee and Steve Smith
rocketed away from Launch Pad 39-A at 2:55 A.M. Central time, arcing
out over the Atlantic Ocean as the 12-ton Telescope soared over
Central Africa at an altitude of about 320 statute miles. Eight and a
half minutes later, Discovery reached orbit, returning to the Shuttle
fleet for the first time since the summer of 1995 when it was shipped
to California for a lengthy maintenance period.
- Later this morning, the astronauts plan to conduct the first of
several rendezvous burns of the Shuttle's maneuvering jets to begin to
close in on Hubble, which is scheduled to be retrieved by Discovery's
robot arm early Thursday morning. Lee, Smith, Harbaugh and Tanner,
working in teams, will then conduct four spacewalks to replace two of
Hubble's key scientific instruments and to install other upgraded
- The astronauts are scheduled to begin an eight-hour sleep period at
10:26 A.M. Central time and will be awakened just before 6:30 this
evening to begin their second day in orbit in which they will checkout
Discovery's robot arm and the spacesuits which will be worn during the
four servicing spacewalks.
- On Tuesday, February 11, 1997, 7:00 p.m. CST, STS-82 MCC Status Report # 2
- The STS-82 astronauts will spend the second day of the mission
preparing Discovery, their tools and even their own bodies for the
upcoming servicing of the Hubble Space Telescope.
- The crew's first activity tonight, after the post-sleep period, will
be to decrease the atmospheric pressure within the crew cabin to 10.2
psi. This slightly lower cabin pressure will help spacewalkers Mark
Lee, Steve Smith, Greg Harbaugh and Joe Tanner maintain the higher
level of oxygen in their bloodstream necessary to safely operate in
the even lower pressure of their spacesuits. It also will eliminate
the need for the spacewalkers."pre-breath" pure oxygen for several
- About the same time, Mission Specialist Steve Hawley will check out
the robot arm that he will use to snare the telescope from orbit early
Thursday morning. He will then use the arm to perform a survey of the
equipment in the payload bay that will be used during the spacewalks.
- Around midnight tonight, crew members will begin checking out the
tools they will use during the telescope servicing activities, and
preparing the airlock for the first the four extravehicular
activities. They will then inspect the tools needed for the rendezvous
itself. Astronauts will close out the day with a check of their
- The crew began its day at 6:25 p.m. with the song."Magic Carpet Ride"
- At the time of crew wake up, Discovery was about 3,100 n.m. behind the
telescope and was closing at a rate of 305 n.m. per orbit. The HST
control team will shortly begin to shut down the telescope's systems
to prepare it for the servicing mission. Capture of the telescope is
currently expected at 1:50 a.m. Thursday morning with the first
spacewalk taking place late that night. All systems on both spacecraft
are performing as expected.
