STS-82 Day 2 Highlights
Back to STS-82 Flight Day 01 Highlights:
- On Wednesday, February 12, 1997, 6:30 a.m. CST, STS-82 MCC Status Report # 3
- Discovery's seven astronauts spent their first full day on orbit
preparing for tomorrow's retrieval of the Hubble Space Telescope by
checking out the Shuttle's robot arm, surveying the payload bay
worksites and testing the spacesuits that will be used for the four
planned spacewalks beginning Thursday night.
- Using the Shuttle's 50-foot remote manipulator system, Mission
Specialist Steve Hawley conducted a survey of the payload bay while
putting the arm through its paces to verify it's health in support the
capture of the telescope, which is scheduled at 1:50 A.M. Central
- The crew cabin's atmospheric pressure was lowered to reduce the
amount of time required to prebreathe oxygen prior to the spacewalks
to be conducted by Mark Lee, Steve Smith, Greg Harbaugh and Joe
Tanner. Those spacewalks are scheduled to occur on consecutive nights
beginning Thursday at about 10:20 p.m.
- To prepare for the spacewalks, the astronauts assembled on the
middeck to checkout all of the tools they will use while servicing the
telescope. They successfully tested the spacesuits they will wear
while working around and in Hubble in the open cargo bay.
- Commander Ken Bowersox and Pilot Scott Horowitz conducted additional
rendezvous maneuvers this morning, designed to adjust Discovery's
closing rate on the telescope so the Shuttle will arrive about 2400
feet below Hubble an hour before its scheduled retrieval in the
morning. At 6 A.M., Discovery was less than a thousand miles behind
the telescope and closing at the preplanned rate.
- The astronauts are scheduled to begin an eight hour sleep period at
about 9:30 this morning and will receive a wakeup call from Mission
Control at 5:25 this afternoon to begin rendezvous activities.
- Discovery continues to orbit the Earth at an altitude of 360 statute
miles will all of this systems in excellent shape.
- On Wednesday, February 12, 1997, 5:00 p.m. CST, STS-82 MCC Status Report # 4
- With its aperture door closed and antennas secure, the Hubble Space
Telescope is standing by to be plucked from its orbit for servicing by
the STS-82 crew.
- Tonight, Commander Ken Bowersox and Pilot Scott Horowitz will
perform the final series of thruster firings to bring the Space
Shuttle Discovery within robot arm's reach of the orbiting
telescope. The maneuver that signals the final stage of the
rendezvous, known as the Terminal Initiation or."TI burn," will occur
shortly after midnight in Houston. Then, as the orbiter approaches,
Bowersox will control firing of the steering jets to make sure they do
not contaminate the sensitive HST instruments.
- When Discovery and HST are close enough, Mission Specialist Steve
Hawley will use the orbiter's robot arm to gently capture the
telescope and pull it to its work platform in the payload bay. Grapple
is scheduled for 2:15 a.m. CST and berthing will occur at
approximately 3 a.m. Astronauts will then use the cameras on the robot
arm and in the payload bay to give Hubble's ground control team a
chance to inspect the exterior of the telescope for the first time
since the first servicing mission in 1993.
- The tools and systems needed for the rendezvous operations and the
four six-hour spacewalks were checked by crew members during the
second day of the mission. All systems are ready to support the
- The first of the spacewalks is set to begin at about 10:20
p.m. Thursday night with astronauts Mark Lee and Steve Smith serving
as the EVA crew members. Lee and Smith will perform the first and
third spacewalks while astronauts Greg Harbaugh and Joe Tanner perform
the second and fourth.
- The crew will start the third day of the mission at 5:25 p.m. CST as
Discovery moves 60 n.m. closer to HST every time it orbits the Earth.
