*Expedition 12 Crew*
The International Space Station crew this week installed an upgrade that
will conserve oxygen during spacewalks, moved the station robotic arm to
prepare for their next spacewalk, and began an experiment that studies
body movements.
Expedition 12 Commander Bill McArthur and Flight Engineer Valery Tokarev
had Monday off to observe the end of the Russian Christmas holidays.
Completing an important upgrade to the station's spacewalk preparation
systems, McArthur and Tokarev installed the Recharge Oxygen Orifice
Bypass Assembly (ROOBA) later in the week. The assembly will conserve
station oxygen during spacewalk preparations when the space shuttle is
docked to the complex. It allows crew members to prebreathe oxygen from
the shuttle rather than use oxygen from station tanks as they prepare
for a spacewalk. Crew members must prebreathe pure oxygen for an
extended period before beginning a spacewalk to prevent decompression
sickness. The new system will be used during the next shuttle mission.
Initiating work with the scientific investigation for Expedition 12,
McArthur put on customized Lycra cycling tights this week for a session
of the Foot/Ground Reaction Forces during Spaceflight, or FOOT
experiment. FOOT investigates the differences between use of the body's
lower extremities on Earth and in space. McArthur wore the instrumented
garb to measure joint angles, muscle activity and forces on his feet
during daily activities.
On Thursday, McArthur maneuvered the station's Canadarm2 robotic arm to
provide television views of an Interface Umbilical Assembly (IUA). The
assembly houses a contingency cable cutter for a line that provides
power, data and video to the station's Mobile Transporter. The Mobile
Transporter is a rail car on which the arm may travel along the
station's truss. A second, identical assembly on the other side of the
transporter inadvertently cut a backup cable for the system last month.
The camera views allowed engineers to survey the remaining intact
assembly and cable. McArthur and Tokarev will install a safing bolt in
the intact system during a Feb. 2 spacewalk.
On Friday, McArthur again maneuvered the arm, positioning cameras to
survey the seal on a station port where cargo modules carried aboard the
shuttle can be docked. Engineers used the view to inspect the Common
Berthing Mechanism on the Unity module for possible debris. Following
that, the arm was moved to another position where it will remain to
provide views of the upcoming spacewalk.
The Elektron oxygen-generation system was activated this week by Tokarev
after being deliberately shut off since mid-December. The Elektron was
off to allow oxygen supplies from the unpiloted Progress 19 cargo
carrier to be used. Tokarev also worked on a number of Russian science
projects throughout the week.
Via ham radio, McArthur answered questions from students at Peterson
Elementary School in his hometown of Red Springs, N.C.; and at the St.
Albert the Great School in North Royalton, Ohio. He also talked with
high school students in Hiroshima, Japan.
Information on the crew's activities aboard the Space Station, future
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 on Friday, Jan. 20, or
earlier if events warrant.
