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.
