Current, Future ISS Crews Complete Active Workweek
The Expedition Six crewmembers have completed another busy workweek
aboard the International Space Station. Their major activity was a
spacewalk conducted by Commander Ken Bowersox and NASA ISS Science
Officer Don Pettit. During the spacewalk, they continued the external
outfitting of the station. 

On the science front, they conducted sessions with the Effects of EVA
and Long-Term Exposure to Microgravity on Pulmonary Function, or PuFF,
experiment and the Investigating the Structure of Paramagnetic
Aggregates from Colloidal Emulsions, or InSPACE, experiment. PuFF is
studying the effect of long-term exposure to microgravity and the
effects of extravehicular activity on lung function, and InSPACE is
studying how particles and clumps of particles respond to an external
magnetic field. 

Preparations continued for the Expedition Seven crew's arrival on April
28 and the Expedition Six crew's departure on May 3. Russian flight
controllers fired the Progress 10 cargo ship's engines Thursday to raise
the outpost's orbit by 2.6 kilometers (1.6 miles). The reboost maneuver
and one that occurred earlier in the month were performed to put the
station in the correct orbit for the Expedition Seven's arrival and
Expedition Six's undocking. 

Meanwhile, Expedition Seven Commander Yuri Malenchenko and Flight
Engineer Ed Lu went to Baikonur Cosmodrome, Kazakhstan, to inspect the
Soyuz TMA-2 spacecraft that will carry them to the station. Expedition
Seven is slated to launch at 10:35 p.m. CDT (0335 GMT) April 25. 

Expedition Seven Next ISS Crew
The International Space Station's next set of residents, the Expedition
Seven crew, is slated to arrive April 28 at 12:50 a.m. CDT (0550 GMT)
aboard the Soyuz TMA-2 spacecraft. The crew consists of Russian
Cosmonaut Yuri Malenchenko and U.S. Astronaut Ed Lu. Malenchenko and Lu
are scheduled to launch from Baikonur Cosmodrome, Kazakhstan, at 10:35
p.m. CDT April 25 (0335 GMT April 26).

Malenchenko, who will serve as commander, is a veteran of two
spaceflights -- Mir 16 and STS-106. Lu, who will serve as a flight
engineer and NASA ISS Science Officer, is a veteran of two shuttle
flights -- STS-84 and STS-106.

They will replace the Expedition Six crew, which has been at the station
since Nov. 25, 2002. Expedition Six Commander Ken Bowersox, Flight
Engineer Nikolai Budarin and NASA ISS Science Officer Don Pettit will
return to Earth on May 3 aboard the Soyuz TMA-1 spacecraft currently
docked to the station.
