More #RealGravity images tonight as #Gravity is up for awards at the #Oscars2014: Expedition 35 Flight Engineers Chris Cassidy (pictured) and Tom Marshburn (out of frame) completed the 5-hour, 30-minute spacewalk on May 11, 2013 to inspect and replace a pump controller box on the International Space Station’s far port truss leaking ammonia coolant. A leak of ammonia coolant from the area near or at the location of a Pump and Flow Control Subassembly was detected on May 9, 2013, prompting engineers and flight controllers to begin plans to support the spacewalk. The device contains the mechanical systems that drive the cooling functions for the port truss.
