Outside the International Space Station, Expedition 35 Flight Engineers Chris Cassidy and Tom Marshburn of NASA conducted a 5-hour, 30-minute spacewalk on the station’s P6 truss to replace a suspect pump controller box which distributes coolant to the station’s thermal control system. The quick-turnaround spacewalk was mounted just 48 hours after an ammonia coolant leak developed on P6. After installing the spare pump, power was turned on, and the system appeared to be working properly with no indications of ammonia leaking from the pump.
