Expedition 15 Commander Fyodor Yurchikhin and Flight Engineer Clay Anderson this week finished preparing their spacesuits for a planned July 23 spacewalk. Yurchikhin and Flight Engineer Oleg Kotov also continued evaluating the computers on the Russian segment of the International Space Station.

During the U.S. spacewalk, Yurchikhin and Anderson will jettison a support post for an exterior video camera and a 1,400-pound, refrigerator-sized tank that is no longer needed. The tank, known as the Early Ammonia Servicer, was designed to replenish ammonia to the temporary cooling system on the station in the event of a coolant leak.
