NASA's Space to Ground: Resetting the Schedule: Week of Oct. 13, 2023

NASA's Space to Ground is your weekly update on what's happening aboard the International Space Station. 

Two United States operating segment spacewalks outside the International Space Station have been rescheduled for no earlier than Thursday, Oct. 19, 2023, and Monday, Oct. 30, as a result of ongoing review by NASA managers and engineers after a coolant leak from a backup radiator on the station’s Nauka multipurpose laboratory module.

The spacewalks were deferred from their original target dates to allow engineers additional time to complete their analysis of the coolant leak, which occurred on Oct. 9 and has now stopped.

During the first spacewalk NASA astronaut Loral O’Hara and European Space Agency (ESA) astronaut Andreas Mogensen will exit the station’s Quest airlock to collect samples for analysis to see whether microorganisms may exist on the exterior of the orbital complex. They also will replace a high-definition camera on the port truss of the station and conduct other maintenance work to prepare for future spacewalks.

O’Hara will serve as extravehicular activity (EVA) crew member 1 and will wear a suit with red stripes. Mogensen will serve as extravehicular crew member 2 and will wear an unmarked suit. U.S. Spacewalk 89 will be the first spacewalk for both crew members.

During the second spacewalk, O’Hara and Jasmin Moghbeli will complete the removal of a faulty electronics box, called a Radio Frequency Group, from a communications antenna bracket and replace one of twelve Trundle Bearing Assemblies on the port truss Solar Alpha Rotary Joint. The bearings enable the station’s solar arrays to rotate properly to track the sun as the station orbits the Earth. During this spacewalk, Moghbeli will serve as EVA crew member 1 and O’Hara will serve as EVA crew member 2. U.S. Spacewalk 90 will be the first spacewalk for Moghbeli and second for O’Hara.
