STS-114 MCC Status Report #12
Sunday, July 31, 2005 - 11:15 p.m. CDT
Mission Control Center, Houston, Texas
Now spacewalk veterans, Astronauts Soichi Noguchi and Steve Robinson will
step outside for the second of three planned spacewalks today at 3:14 a.m.
CDT. The sole objective of the 6 ½-hour excursion is to replace a failed
International Space Station attitude control gyroscope.
The pair will have about an hour of setup time after exiting Space Shuttle
Discovery's airlock and positioning themselves at the Station's Z1 truss
segment. Mission Control will shut down the failed Control Moment Gyroscope
1 (CMG1) about 4:09 a.m. CDT and then give a go for the spacewalkers to
start removing it about 15 minutes later. Mission Specialist Andy Thomas
will choreograph the activities from inside and relay information from
Mission Control to the spacewalkers.
Noguchi will take the failed CMG to Discovery's cargo bay while riding the
Station's robot arm. He will temporarily store it until the new gyro is
removed and the old one can be placed in its carrier with Robinson's help.
Noguchi will then carry the new gyro at the end of the robot arm to the Z1
truss. Discovery Pilot Jim Kelly and Mission Specialist Wendy Lawrence will
operate Canadarm2 for the spacewalk.
After it is installed, Station flight controllers will power up and check
out the new gyroscope about 8:14 a.m. CDT and start it up at 8:39 a.m. CDT.
With CMG1 replaced, the full complement of four gyroscopes will be available
for Station operations. CMG2 has operated well since the spacewalkers
restored power to it in the first spacewalk Saturday.
Inside the orbiting complex, Station residents Sergei Krikalev and John
Phillips and Discovery Commander Eileen Collins and Mission Specialist
Charlie Camarda will continue transferring equipment and supplies between
the two vehicles. Collins will focus on collecting byproduct water from
Discovery's power generation system for transfer to Station.
Discovery's crew was awakened at 10:09 p.m. CDT by the song "Walk of
Life," by Dire Straits for Robinson. The Space Station crew was
awakened at 10:39 p.m. CDT by a tone onboard.
The crews of Discovery and the Space Station are scheduled to go to sleep
about 2:09 p.m. CDT.
The next STS-114 mission status report will be issued Monday afternoon, or
earlier, if events warrant.
