Expedition 55 Flight Engineers Drew Feustel and Ricky Arnold of NASA moved the Pump Flow Control Subassembly from a spare parts platform on the station’s truss to the Dextre Robotic Arm.
The Pump Flow Control Subassembly drives and controls the flow of ammonia through the exterior portions of the station’s cooling system.
The team then removed and replaced a camera group and a degraded Space to Ground Transmitter Receiver Controller, and was also able to complete several get-ahead tasks.
Spacewalkers have now spend a total of 54 days, 16 hours and 40 minutes working outside the station in support of assembly and maintenance of the orbiting laboratory.
