NASA astronauts Victor Glover and Michael Hopkins concluded their spacewalk at 3:01 p.m., EST, March 13, 2021, after 6 hours and 47 minutes.
In the fifth spacewalk of the year outside the International Space Station, the two astronauts successfully completed tasks to service the station’s cooling system and communications gear.
The duo began their work on the station’s port truss, or “backbone,” completing tasks that were deferred from previous spacewalks. The spacewalkers successfully vented the early ammonia system, relocated one of its jumper lines, and serviced the Columbus Bartolomeo payload platform, including routing three of four cables on the Payload Position interface and configuring a cable for an amateur radio system. The astronauts deferred the task of installing clamps on Bartolomeo in order to route cables for high-definition cameras. The pair also replaced a wireless antenna assembly on the Unity module and installed hardware to provide additional structural integrity on the airlock.
This was the fourth career spacewalk for Glover and the fifth in Hopkins’s career. Glover has now spent a total of 26 hours and 7 minutes spacewalking. Hopkins now has spent a total of 32 hours and 1 minute spacewalking.
Space station crew members have conducted 237 spacewalks in support of assembly and maintenance of the orbiting laboratory. Spacewalkers have now spent a total of 62 days, 3 hours and 54 minutes working outside the station.
