Spacewalk with NASA Astronauts Josh Cassada and Frank Rubio (Dec. 21)


NASA astronauts Josh Cassada and Frank Rubio are conducting a spacewalk on Wednesday, Dec. 21, to install the fourth International Space Station Roll-Out Solar Array (iROSA) to increase power generation on the station’s Port-4 truss structure. This spacewalk is the second of a pair this month to install the iROSAs and is scheduled to begin at 7:45 a.m. EST (12:45 UTC), when the astronauts switch on their spacesuit battery packs. The spacewalk is expected to last about seven hours.

Rubio (wearing the suit with red stripes) and Cassada (wearing the unmarked suit) are part of NASA’s SpaceX Crew-5 mission, which arrived at the station on Oct. 6, 2022. This is the third spacewalk for both astronauts.
