International Space Station Status Report #03-2

Expedition Six Crew

Preparations continue in orbit for the 50th spacewalk dedicated to
assembly and maintenance of the International Space Station. Commander
Ken Bowersox and NASA ISS Science Officer Don Pettit are scheduled to
step outside Wednesday about 6:30 a.m. CST. 

The crewmembers spent this week reviewing the timeline and procedures,
organizing tools, and preparing the spacesuits and the Quest airlock for
the 6½-hour spacewalk. During the outing, Bowersox and Pettit will
release launch restraints to permit deployment of a cooling radiator on
the Port 1 truss segment and clean the attach point on the Unity Node for
station cargo modules. They also will install a work light and a foot
restraint on an astronaut handcar for future spacewalking construction
workers to use. Flight Engineer Nikolai Budarin will provide support for
Bowersox and Pettit from inside the station. NASA television spacewalk
coverage starts at 5 a.m. CST Wednesday. 

Bowersox provided data to scientists for the FOOT (Foot/Ground Reaction
Forces During Spaceflight) experiment, which looks at how the arms, hips,
knees, legs and feet move in the absence of gravity, and at what changes
occur in bones and muscles during spaceflight. Bowersox wore a special
pair of cycling pants with 20 sensors on his legs and additional sensors
on his arms that took electrical impulse measurements throughout his
workday Tuesday. 

All three crewmembers participated in a monthly lung-function test, to
study the effects of weightlessness. The crewmembers forcefully exhaled
into a device which stored lung capacity measurements in an onboard
medical computer. The session served as the pre-spacewalk reading for
Bowersox and Pettit, while the experiment also studies how wearing
low-pressure spacesuits affects lung performance. They will participate
in another session after the spacewalk. 

Thursday, Bowersox and Pettit operated the space station robotic arm,
Canadarm2, to do camera surveys of exterior hardware in the station's
expanding thermal control system. They maneuvered Canadarm2 into
positions to inspect the location of thermal blankets on cooling lines
and the S1 and S0 trusses and also survey the condition of the radiator
on the P6 truss. Engineers on the ground will review the footage for any

launch dates, as well as station sighting opportunities from anywhere on
the Earth, is available on the Internet at:

The next station status report will be issued Wednesday, Jan. 15, after
the ISS spacewalk, or sooner if events warrant.
