NASA astronauts Victor Glover and Michael Hopkins are scheduled to exit the International Space Station’s Quest airlock Saturday to complete tasks that were deferred from earlier spacewalks to allow for the successful installation of modification kits in preparation for future solar array upgrades.
The pair will set their spacesuits to battery power about 7:30 a.m. EST tomorrow, signifying the start of their spacewalk, which is expected to last about six and a half hours. NASA will begin its live coverage on NASA Television, the NASA app, and the agency’s website at 6 a.m.
During the spacewalk, Glover and Hopkins will vent early ammonia system jumper cables and relocate one outside the Quest airlock. The duo also will connect cables for the Columbus Bartolomeo payload platform, continuing work from a Jan. 27 spacewalk, and replace a cable for an amateur radio system. Additionally, the astronauts will replace a wireless antenna assembly on the Unity module, install a “stiffener” on the airlock’s thermal cover to provide additional structural integrity, and route cables to enable ethernet capabilities for two high-definition cameras on the station’s port truss, or “backbone.”
This will be the 237th spacewalk in support of space station assembly. Glover will be designated extravehicular crew member 1 (EV 1) and wear a spacesuit bearing red stripes. Hopkins will be extravehicular crew member 2 (EV 2), wearing an unmarked suit.
Glover and Hopkins both arrived at the space station in November as part of NASA’s SpaceX Crew-1 mission. This will be the fourth career spacewalk for Glover, and the fifth for Hopkins.
