The Expedition 15 crew aboard the International Space Station spent 
Friday working with scientific experiments and preparing for the arrival 
of a Progress cargo craft and space shuttle Endeavour in August.

Flight Engineer Clay Anderson packed items to be returned to Earth 
aboard Endeavour when it completes the STS-118 mission. He also gathered 
tools that will be used during that mission's three spacewalks. 
Endeavour is set to launch on Aug. 7 and dock with the station on Aug. 9.

Anderson also transferred and stowed the equipment for the Anomalous 
Long Term Effects in Astronauts' Central Nervous System payload, an 
experiment which measures the effect of the exposure of crew members to 
cosmic radiation.

Flight Engineer Oleg Kotov performed maintenance on the station's 
exercise treadmill, repairing its roller bearings, and conducted a 
repressurizaton of oxygen using the tanks in the docked ISS Progress 24 
cargo craft.

Progress 24 will undock from the Pirs docking compartment on Aug. 1, 
burning up in the Earth’s atmosphere as it deorbits. Progress 26 is 
scheduled for launch on Aug. 2 and will reach the station on Aug. 5.

On Monday, Anderson and Commander Fyodor Yurchikhin conducted a 7-hour, 
41 minute spacewalk. Anderson jettisoned a 1,400 pound, 
refrigerator-size ammonia reservoir known as the Early Ammonia Servicer 
by pushing it opposite of the station's direction of travel. Anderson 
and Yurchikhin also installed a television camera support or stanchion, 
reconfigured a power supply for an antenna assembly, and performed 
several get-ahead tasks.
