Commander Fyodor Yurchikhin and Flight Engineer Clay Anderson will put 
on their U.S. spacesuits for Thursdayís dry run activities. Flight 
Engineer Oleg Kotov will test his robotic skills and maneuver the 
stationís robotic arm, Candarm2, to a pre-determined position. During 
Mondayís spacewalk one of Andersonís tasks is to jettison the 
1,400-pound Early Ammonia Servicer (EAS).

A docked Progress 25 cargo craft will fire its thrusters on July 21 and 
23 raising the International Space Stationís orbit. The reboost provides 
the proper phasing for an upcoming Progress 26 launch and docking. The 
Progress firing also clears the station after the EAS is jettisoned and 
provides flight day three rendezvous opportunities when space shuttle 
Endeavour arrives on mission STS-118.

The Progress 24 cargo craft will undock from the Pirs docking 
compartment on Aug. 1 and burn up in the Earthís atmosphere. Progress 26 
is scheduled for launch on Aug. 2 and will reach the station on Aug. 5. 
Two days later on Aug. 7, space shuttle Endeavour is targeted for launch 
with a station rendezvous and docking planned for Aug. 9.
