The crew members of Expedition 68 are preparing to exit the International Space Station‘s Quest airlock for a spacewalk expected to begin about 8:30 a.m. EST and last approximately seven hours.
NASA astronauts Josh Cassada and Frank Rubio will exit the station’s Quest airlock to install an International Space Station Roll-Out Solar Array (iROSA) to augment power generation for the 4A power channel on the station’s port truss structure. The iROSAs will increase power generation capability by up to 30%, increasing the station’s total available power from 160 kilowatts to up to 215 kilowatts.
Rubio will serve as extravehicular crew member 1 (EV 1) and will wear a suit with red stripes. Cassada will serve as extravehicular crew member 2 (EV 2) and will wear the unmarked suit. The spacewalk will be the third for both Cassada and Rubio.
