NASA is targeting a two-hour test window that opens at 3 p.m. EDT Thursday, March 18, for the second hot fire test of the core stage for the agency’s Space Launch System (SLS) rocket at NASA’s Stennis Space Center near Bay St. Louis, Mississippi.

NASA astronauts Victor Glover and Michael Hopkins concluded their spacewalk at 3:01 p.m. EST, 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 (PAPOS) 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.

NASA astronauts Victor Glover and Michael Hopkins have begun their spacewalk outside the International Space Station to service the station’s cooling system and communications gear.
The pair switched their spacesuits to battery power at 8:14 a.m. EST to begin the spacewalk, which is expected to last about six and a half hours.
Watch the spacewalk on NASA TV, the NASA app, and on the agency’s website.
Glover is extravehicular crew member 1 (EV 1), wearing a spacesuit bearing red stripes and using helmet camera #20. Hopkins is extravehicular crew member 2 (EV 2), wearing the unmarked spacesuit and helmet camera #22.
Glover and Hopkins will traverse out the station’s backbone truss structure to vent the early ammonia system before relocating one of its jumper lines. Hopkins will then connect cables for the Columbus Bartolomeo payload platform, continuing work from a Jan. 27 spacewalk, and Glover will replace a wireless antenna assembly on the Unity module. The pair will then work together to install hardware on the airlock’s thermal cover and route cables to two high-definition cameras on the port truss.
This is the 237th spacewalk in support of space station assembly.

NASA Television coverage of today’s spacewalk NASA astronauts Victor Glover and Michael Hopkins is now underway and is also available on the NASA app and the agency’s website.
The crew members of Expedition 64 are preparing to venture outside the International Space Station for a spacewalk expected to begin around 7:30 a.m. EST and last about six and a half hours.
The crew is in the airlock and have donned their suits in preparation to exit the airlock and begin today’s activities to service the station’s cooling system and communications gear.
Glover and Hopkins will begin work on the station’s port truss, where they will vent the early ammonia system jumper lines and relocate one of them to the outside of the airlock, followed by translating to the Columbus module to connect cables for the Bartolomeo payload platform and replace a cable for an amateur radio system. Then, the astronauts will replace a wireless antenna assembly on the Unity module, install a “stiffener” on the airlock’s thermal cover, and route cables to provide ethernet capabilities for two high-definition cameras on the station’s port truss.
Leading the Mission Control team today is Flight Director Chris Edelen with support from Art Thomason as the lead spacewalk officer.

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.
