The crew members of Expedition 68 are preparing to exit the International Space Station‘s Quest airlock for a spacewalk expected to begin about 7:25 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 3A power channel on the station’s starboard truss structure.
In addition to installing an iROSA, the spacewalkers will disconnect a cable to allow the 1B power channel to be reactivated after it was shut down due to a power trip in its electrical system. The disconnection of the cable will isolate the affected portion of the array and restore the channel to 75% of its normal operating capacity.
Cassada will serve as extravehicular crew member 1 (EV 1) and will wear a suit with red stripes. Rubio will serve as extravehicular crew member 2 (EV 2) and will wear the unmarked suit. The spacewalk will be the second for both Cassada and Rubio.
