Feustel is wearing the suit bearing the red stripes, and Arnold’s suit has no stripes. Views from a camera on Feustel’s helmet are designated with the number 17, and Arnold’s is labeled with the number 18. Feustel is designated extravehicular crew member 1 (EV1) for this spacewalk, the eighth of his career. Arnold, embarking on his fourth spacewalk, is extravehicular crew member 2 (EV2).
Expedition 55 Flight Engineers Drew Feustel and Ricky Arnold of NASA completed the fifth spacewalk of this year at 2:10 p.m. EDT, lasting 6 hours, 31 minutes. The two astronauts moved the Pump Flow Control Subassembly (PFCS) from a spare parts platform on the station’s truss to the Dextre robotic arm. The PFCS 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 spent a total of 54 days, 16 hours and 40 minutes working outside the station in support of assembly and maintenance of the orbiting laboratory.
