Default ISS Status Report No. 04 - 2004

International Space Station Status Report #04-4
4 p.m. CST, Friday, Jan. 16, 2004
Expedition 8 Crew

In an effort to gather more data regarding normal air pressure fluctuations
onboard the International Space Station, Expedition 8 Commander Mike Foale
and Flight Engineer Alexander Kaleri ended their week by closing several
interior hatches.

Foale and Kaleri will spend most of the weekend in a smaller portion of the
station than usual, primarily the Zvezda living quarters module. Foale and
Kaleri floated into the Zvezda shortly after 2 p.m. Central time, closing
several hatches behind them. Flight controllers will monitor air pressure in
the station modules during that time to verify that the pressure aboard is
stable and to gather baseline data on normal air pressure fluctuations in
the complex.

For the data gathering session, the Station cabin has been divided into four
sections. The one where the crew is staying includes Zvezda, the Soyuz
spacecraft, the Pirs docking compartment and the Progress cargo vehicle.
Another section includes the Unity connecting node and the Quest airlock. A
third section is the Zarya control module and Pressurized Mating Adapter 1.
The fourth section is the Destiny laboratory.

All of the hatches will be reopened Sunday afternoon.

On Jan. 11, Foale tracked down the probable cause of a slight pressure decay
that had been detected aboard the station since late December. Foale found a
leaking flex hose that is part of a system that prevents fogging within
Destiny's window. The hose was removed and the leak stopped. Engineers are
evaluating plans to launch a replacement hose on the next Progress supply
vehicle on Jan. 29.

Earlier this week, Kaleri replaced a liquid separation unit for the Russian
Elektron oxygen generation system, restoring that system to full function.
The week also included a number of science and medical experiment activities
for the crew. Kaleri performed an assessment of the effects of
weightlessness on the inner ear using a special Russian suit and collected
air samples as part of another Russian program designed to help assess the
microbial environment aboard the ISS.

Foale conducted his second session with the Foot/Ground Reaction Forces
During Spaceflight (FOOT) experiment, gathering several hours of additional
data. For the experiment, Foale dons a special pair of instrumented leggings
that allow researchers to measure forces on the feet, joint angles and
muscle activity. Foale also participated in a Hand Posture Analyzer
investigation, which uses a special glove to assess the changes in how
humans reach, grasp, manipulate and transport objects during long periods in
weightlessness.

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:

Details on Station science operations can be found on an Internet site
administered by the Payload Operations Center at NASA's Marshall Space
Flight Center in Huntsville, Ala., at:

The next ISS status report will be issued on Friday, Jan. 23, or earlier if
events warrant.
