Expedition
Six Spacewalks
The Expedition
Six crew conducted two spacewalks during its stay at the International
Space Station. Both were based out of the Quest Airlock, and the
spacewalkers used U.S. spacesuits, which are called Extravehicular
Mobility Units, or EMUs. The
crew was originally scheduled to conduct only one spacewalk, but
a second was added to the manifest for April 8 in order to prepare
for future assembly missions.
The two Expedition
Six extravehicular activities bring the total number of spacewalks
conducted in support of ISS assembly and maintenance to 51. Twenty-six
have been based out of the station, with 17 staged from Quest. Bowersox
and Pettit accumulated 13 hours and 17 minutes of spacewalking time
at the station.

Spacewalk
1
Ken Bowersox, Don Pettit
Time: 6 hours, 51 minutes
Start time: 6:50 a.m. CST (1250 GMT) Jan. 15, 2003
End time: 1:41 p.m. CST (1941 GMT) Jan. 15, 2003
Bowersox and
Pettit continued outfitting and activating the International Space
Station's newest component, the P1 (P-One) Truss. The P1's radiator
assembly was a major focus during the spacewalk. Bowersox and Pettit
released the remaining launch locks on the radiator assembly, which
allowed the radiator assembly to be deployed. Other scheduled tasks
completed included removing some debris that was on a sealing ring
on the Unity Module's Earth-facing docking port, and they tested
an ammonia reservoir on the station's P6 Truss. They were unable
to complete one scheduled task -- the installation of a light fixture
on one of the station's Crew and Equipment Translation Aid, or CETA,
carts. The fixture's attachment will be rescheduled for a future
spacewalk.
To complete
the spacewalk, Bowersox and Pettit cut away a thermal cover strap
that apparently interfered with the rotation of the Quest Airlock's
hatch and delayed the start of the extravehicular activity.

Ken Bowersox, Don Pettit
Time: 6 hours, 26 minutes
Start time: 7:40 a.m. CDT (1240 GMT) April 8, 2003
End time: 2:06 p.m. CDT (1906 GMT) April 8, 2003
Bowersox and
Pettit reconfigured cables on the S0 (S-Zero), S1 and P1 Trusses
for future Integrated Truss Structure component deliveries and replaced
a Power Control Module on the Mobile Transporter. They provided
Control Moment Gyro No. 2 with a redundant power channel capability
by rerouting cables. Then, they installed Spool Positioning Devices
on Destiny Laboratory heat exchangers and reinstalled a thermal
cover on an S1 Radiator Beam Valve Module. Bowersox and Pettit also
unfurled a light stanchion on the CETA cart that did not unfurl
properly during their first spacewalk.
