HOUSTON, July 23 (UPI) -- Two International Space Station crew members Monday successfully conducted a 7-hour, 41-minute spacewalk.
Astronaut Clay Anderson and Cmdr. Fyodor Yurchikhin removed and jettisoned a refrigerator-sized ammonia reservoir, installed a television camera stanchion, reconfigured a power supply for an antenna assembly, and performed several other tasks.
Riding on the end of the space station's robotic arm maneuvered by cosmonaut Oleg Kotov, Anderson jettisoned the ammonia unit by shoving it away from the station's direction of travel.
After the spacewalk, the docked Progress 25 cargo craft's thrusters were fired, raising the station's orbit. National Aeronautics and Space Administration controllers in Houston said that provided the proper phasing for an upcoming Progress 26 docking, as well as the arrival next month of space shuttle Endeavour and its STS-118 crew.
