     The five-crew members aboard the International Space 
Station are busy with handover briefings and scientific 
experiments following their arrival early last Wednesday. The 
outgoing Expedition 8 crew and incoming Expedition 9 crew 
held a Change of Command Ceremony today.
Expedition 9 Commander Gennady Padalka and NASA ISS Science 
Officer Mike Fincke docked their Soyuz spacecraft to the port 
of the Zarya Control Module at 1:01 a.m. EDT Wednesday April 
21. They opened hatches and boarded the Station about an hour 
later, beginning their six-month stay.
With them on the Soyuz was European Space Agency Astronaut 
Andre Kuipers of the Netherlands. He will spend nine days 
aboard the Station conducting scientific investigations. 
Kuipers will return to Earth with Expedition 8 Commander 
Michael Foale and Flight Engineer Alexander Kaleri. Foale and 
Kaleri arrived on the Station October 20, 2003.
The Expedition 8 Soyuz capsule is scheduled to undock from 
the Pirs Docking Compartment, where it has been during their 
mission, at 4:52 p.m. EDT, Thursday. The landing is scheduled 
for Thursday night at 9:09 p.m. EDT, on the steppes of 
Early last Thursday, during their Daily Planning Conference, 
crewmembers were told one of the Station's three operating 
Control Moment Gyroscopes, CMG 2, had gone off line at about 
4:20 p.m. EDT on Wednesday. The CMGs use power from the solar 
arrays to control the Station's orientation. Flight 
controllers traced the problem to a Remote Power Controller 
Module (RPCM), a kind of remotely controlled circuit breaker 
that had malfunctioned and cut off power to the gyroscope. 
The RPCM is mounted on the top of the Station's central truss 
segment, above the U.S. Laboratory Destiny.
Two CMGs continue to operate and are sufficient for 
controlling the Station's orientation until the RPCM is 
replaced. Flight controllers are planning a spacewalk. It 
will likely happen within the next month. Crewmen will 
replace the RPCM with a spare unit and restore operation of 
CMG-2. A spare RPCM is aboard the Station.
