The main objective of this EVA was to retract a thermal radiator on the port truss. This radiator was supposed to be retracted during Expedition 45 EVA 2 (November 6, 2015) but was not completed. The radiator had been deployed on Expedition 33 EVA 1 (November 1, 2012) in an attempt to isolate a coolant leak. Additional completed tasks included installing HD Video Cameras on the port/outboard side of the station (one zenith, one nadir), applying additional torque to SARJ bolts, photographing the inside of the SARJ, tying back a protective blanket covering hardware which will be robotically manipulate later, and tying back Crew and Equipment Translation Aid (CETA) Cart brake handles to keep them out of the SARJ rotation envelope.[7][8][9]
