Expedition 70 Flight Engineers Oleg Kononenko (suit with red stripes) and Nikolai Chub (suit with blue stripes), from Russia's space agency Roscosmos, are pictured during a spacewalk to inspect a backup radiator, deploy a nanosatellite, and install communications hardware on the International Space Station's Nauka science module.

Oleg and Nikolai concluded their spacewalk Oct. 25, 2023, at 9:30 p.m. EDT after 7 hours and 41 minutes. During the spacewalk, Kononenko and Chub inspected and photographed an external backup radiator on the Nauka multipurpose laboratory module. They also isolated the radiator from Nauka’s cooling system.

Furthermore, the two cosmonauts released a nanosatellite to test solar sail technology. Additionally, the cosmonauts installed a synthetic radar communications system. This was the sixth spacewalk in Kononenko’s career, and the first for Chub. It is the 268th spacewalk for space station assembly, maintenance, and upgrades.

On Nov. 1, 2023, NASA astronauts Loral O’Hara and Jasmin Moghbeli are scheduled to exit the station’s Quest airlock. U.S. Spacewalk 89 will be the first for both Moghbeli and O’Hara. Moghbeli will serve as extravehicular activity crew member 1 and will wear a suit with red stripes. O’Hara will serve as extravehicular crew member 2 and will wear an unmarked suit.
