Astronauts Take Day Off Following Spacewalk

Four Expedition 68 crew members took Monday off following a busy weekend of spacewalk activities. The rest of the International Space Station crew focused on electronics, life support, and Orlan spacesuit maintenance.

NASA astronauts Josh Cassada and Frank Rubio are relaxing today following a spacewalk on Saturday that saw the successful installation of a roll-out solar array on the station’s Starboard-4 truss segment. The duo then spent Sunday cleaning up after the spacewalk in the Quest airlock and discussing the results of the excursion with specialists on the ground. Flight Engineers Nicole Mann of NASA and Koichi Wakata of the Japan Aerospace Exploration Agency (JAXA) also took Monday off having assisted the spacewalkers over the weekend.

The next spacewalk is planned later this month to relocate a radiator from the Rassvet module to the Nauka multipurpose laboratory module. Commander Sergey Prokopyev and Flight Engineer Dmitri Petelin are replacing pumps inside their Orlan spacesuits today as they prepare for that spacewalk.

Flight Engineer Anna Kikina spent the day servicing a variety of electronics and life support hardware aboard the orbiting lab. She replaced gear and reconfigured cables then worked on the Nauka module’s ventilation system.

Spacewalkers Complete New Solar Array Installation on Station

Expedition 68 Flight Engineers Josh Cassada and Frank Rubio of NASA concluded their spacewalk at 2:21 p.m. EST after 7 hours and 5 minutes.

Cassada and Rubio completed their major objectives for today to install an International Space Station Roll-Out Solar Array (iROSA) and disconnect a cable to ensure the 1B channel can be reactivated. They also completed an additional task to release several bolts for the upcoming iROSA installation on the 4A power channel on the port truss.

It was the 256th spacewalk in support of space station assembly, upgrades and maintenance, and was the second spacewalk for both astronauts. Cassada and Rubio are in the midst of a planned six-month science mission living and working aboard the microgravity laboratory to advance scientific knowledge and demonstrate new technologies for future human and robotic exploration missions, including lunar missions through NASA’s Artemis program.

The next U.S. spacewalk is scheduled for Monday, Dec. 19, to install an iROSA on the 4A power channel on the port truss. This will be the fourth iROSAs out of a total six planned for installation. 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.

Spacewalkers Exit Station to Install Roll-Out Solar Array

Expedition 68 Flight Engineers Josh Cassada and Frank Rubio of NASA began a spacewalk at 7:16 a.m. EST 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, designated extravehicular crew member 1 (EV1), is wearing a suit with red stripes. Rubio, designated extravehicular crewmember 2 (EV 2), is in an unmarked suit. Coverage of the spacewalk continues on NASA Television, the NASA app, and the agency’s website.
