INTERNATIONAL SPACE STATION STATUS REPORT: SS07-16

HOUSTON - The Expedition 14 crew of the International Space Station
was busy this week performing fitness evaluations, working on
scientific experiments and preparing for the arrival of the
Expedition 15 crew.

Cosmonauts Fyodor Yurchikhin, Expedition 15 commander, and Oleg Kotov,
Expedition 15 flight engineer, and spaceflight participant Charles
Simonyi, a U.S. businessman, are scheduled to launch from the
Baikonur Cosmodrome in Kazakhstan at approximately 12:30 p.m. CDT
Saturday. Their Soyuz TMA-10 spacecraft is scheduled to dock with the
station at approximately 2:12 p.m. Monday.

The Expedition 14 crew, Commander Michael Lopez-Alegria and Flight
Engineer Mikhail Tyurin, will return to Earth with Simonyi on April
20. In preparation for their departure, Lopez-Alegria and Tyurin
reviewed descent procedures.

Suni Williams, who joined Expedition 14 in progress, will remain on
the station as an Expedition 15 crew member for the first part of its
increment. The two crews held a space-to-ground conference on
Wednesday discussing upcoming mission activities.

On Monday, Lopez-Alegria set a new U.S. single-mission spaceflight
record, passing the 196-day mark previously set by station crew
members Dan Bursch and Carl Walz in 2001 and 2002.

The Expedition 14 crew performed periodic fitness evaluations this
week. Additionally, they worked on a video tape recorder and on a
faulty light of an ophthalmoscope that was used during a health
check. They downloaded information from the Internal Wireless
Instrumentation System, or IWIS, which monitors the health of the
station’s systems.

The crew continued scientific activities aboard the station. Williams
tested a bacteria detection instrument developed by researchers at
Marshall Spaceflight Center in Huntsville, Ala., and industry
partners. The device, Lab-On-a-Chip Application Development Portable
Test System (LOCAD-PTS) is a portable bacteria detection system small
enough to fit into a compact ice cooler. Four more sessions with
LOCAD-PTS are planned for upcoming weekend science sessions.

Lopez-Alegria and Tyurin tested their hand-eye coordination by
completing their sixth sessions with the Test of Reaction and
Adaptation Capability (TRAC) experiment. The experiment studies
whether the decline of motor skills during spaceflight is a result of
the brain adapting to space. The hand-eye coordination test is
performed before, during and after the mission.

The crew also continued their work with the Anomalous Long-Term
Effects in Astronauts’ Center Nervous System (ALTEA) experiment.
Using an instrumented helmet, the experiment measures the cosmic
radiation that passes through a crew member’s head, brain activity
and visual perception. The experiment should help researchers better
understand what levels of cosmic radiation crew members are exposed
to and develop countermeasures for future long-duration spaceflights.

The next station status report will be issued following the launch of
Soyuz TMA-10 on Saturday or earlier if events warrant.
