*International Space Station Status Report #05-45*
*1 p.m. CDT Friday, September 16, 2005*
*Expedition 11 Crew*
The installation of a replacement part for an oxygen-generating system,
unpacking a recently arrived cargo carrier and the disassembly of a
radiation-detection experiment highlighted this week's activities aboard
the International Space Station.
Expedition 11 Commander Sergei Krikalev and NASA Science Officer John
Phillips are scheduled to activate the Elektron oxygen-generation system
with its new liquids unit on Monday. The Elektron breaks down water into
oxygen for use in the station's atmosphere. The Elektron has not
functioned for several months. Adequate oxygen supplies are available on
the station from tanks and Solid Fuel Oxygen Generators.
The new liquids unit arrived aboard the ISS Progress 19 cargo craft,
which docked to the complex at 9:42 a.m. CDT Saturday. The Progress
craft brought 2.6 tons of cargo to the station. Krikalev and Phillips
began unloading the cargo on Sunday.
The Progress brought more than 2,700 pounds of dry cargo to the station,
including food, equipment, supplies, clothing and components of
scientific experiments. The rest of the cargo included fuel for the
station's thrusters, water and oxygen. Unloading continued
intermittently through the week.
After a light-duty day Monday, the crew transferred Progress cargo and
entered the items into the station's computerized, bar-coded inventory
management system on Tuesday. Much of Wednesday was devoted to
disassembly of the Matroshka radiation experiment, retrieved from the
exterior of the station during an August spacewalk, for return to Earth.
A major part of the European Space Agency Matroshka experiment,
developed and built in Germany and operated through the German Space
Agency's Microgravity User Support Center in Cologne, is a
human-torso-like device. It was launched on a Progress in January 2004
and installed on the outside of the Zvezda Service Module the following
month.
Its interior is similar in density to a human's, and 20 radiation
detectors are mounted in positions of major human organs. Other
detectors inside the station also gathered data for transmission to
Earth and station computers. The experiment is designed to better
understand the exposure of astronauts, including those making
spacewalks, to radiation.
In addition to the Elektron liquids unit replacement, Thursday work
included setup of hardware for the Foot/Ground Reaction Forces During
Spaceflight (Foot) experiment. Phillips put on customized Lycra cycling
tights for his fifth and final session of the experiment. Foot
investigates the differences between use of the body's lower extremities
on Earth and in space, as well as changes in the musculoskeletal system
during spaceflight.
During the session, Phillips wore the instrumented Lower Extremity
Monitoring Suit, or LEMS, which measures joint angles, muscle activity
and forces on the feet while exercising. During the final run, a special
exercise protocol was used to measure forces Phillips experiences on the
cycle ergometer and the Resistive Exercise Device.
Taking force measurements while running through the range of settings
with each piece of exercise equipment helps determine the settings
necessary to match the forces that bones experience during exercise on
Earth. Matching those forces during exercise is critical to reducing the
amount of bone lost while in weightlessness.
Also this week, flight controllers and engineers in Houston assisted
with the transition aboard the station to a faster advanced portable
computer software. The transition was completed Wednesday. Flight
controllers also maneuvered station cameras to capture images of
Hurricane Ophelia several times this week as it approached the Carolina
coast.

launch dates, and station sighting opportunities from anywhere on the

The next station status report will be issued on Thursday, Sept. 22, or
earlier if events warrant.
