Expedition 53 Commander Randy Bresnik and Flight Engineer Joe Acaba of NASA completed a 6 hour, 49 minute spacewalk at 2:36 p.m. EDT. The two astronauts installed a new camera system on the Canadarm2 robotic arm’s latching end effector, an HD camera on the starboard truss of the station and replaced a fuse on the Dextre robotic arm extension.

The duo worked quickly and were able to complete several “get ahead” tasks. Acaba greased the new end effector on the robotic arm. Bresnik installed a new radiator grapple bar. Bresnik completed prep work for one of two spare pump modules on separate stowage platforms to enable easier access for potential robotic replacement tasks in the future. He nearly finished prep work on the second, but that work will be completed by future spacewalkers.

This was the fifth spacewalk of Bresnik’s career (32 hours total spacewalking) and the third for Acaba (19 hours and 46 minutes total spacewalking). Space station crew members have conducted 205 spacewalks in support of assembly and maintenance of the orbiting laboratory. Spacewalkers have now spent a total of 53 days, 6 hours and 25 minutes working outside the station.
