INTERNATIONAL SPACE STATION STATUS REPORT: SS07-11

HOUSTON - The International Space Station's Expedition 14 crew
continued work this week on scientific experiments, station
maintenance and clean up following a Feb. 22 Russian spacewalk.

An altitude reboost engine firing planned for Friday was postponed
following the launch delay of Space Shuttle Atlantis earlier this
week. The STS-117 mission was targeted for liftoff on March 15. The
shuttle mission was put on hold following a hail storm Monday. The
storm caused damage requiring repair to the shuttle's external fuel
tank foam.

Russian flight controllers now plan two engine firings on March 16 and
28 to increase the station's altitude, which will place the station
in the desired orbit for arrival of a Soyuz spacecraft due to launch
April 7. The Soyuz will bring Expedition 15 Commander Fyodor
Yurchikhin, Flight Engineer Oleg Kotov and spaceflight participant
Charles Simonyi to the station. Docking to the station is due April
9. Expedition 14 Commander Mike Lopez-Alegria, Flight Engineer
Mikhail Tyurin and Simonyi plan to land in Kazakhstan April 19.

Space station managers are reviewing the work planned aboard the
station for the remaining weeks of Expedition 14 and for Expedition
15 in light of the shuttle launch delay. The review seeks to optimize
use of the crews' time due to the shuttle's delay.

The station crew Thursday was awakened briefly by a caution signal
when the starboard Thermal Radiator Rotary Joint (TRRJ) experienced a
dropout in commands from the Rotary Joint Motor Controller. The TRRJ
automatically defaulted to another command link, and there was no
impact to operations. Engineers are analyzing what may have caused
the problem. The rotary joint turns the radiator to provide the best
possible cooling.

Flight Engineer Suni Williams practiced on a laptop computer
simulation Wednesday to maintain her skill in using the station's
Canadarm2 robotic arm. She also joined her fellow crewmates in the
Test of Reaction and Adaptation Capabilities (TRAC) experiment to
gather hand-eye coordination data before, during and after their
mission. TRAC Principal Investigator Dr. Otmar Bock of the German
Sport University in Cologne, Germany, hopes to better understand how
the brain adapts during spaceflight. The experiment will be performed
during both Expedition 14 and Expedition 15.
