In a report published September 3, 2026, NASA said the Expedition 75 crew spent that Thursday stowing tools and tethers used during a September 1 spacewalk. Station commander Jessica Meir of NASA and ESA flight engineer Sophie Adenot worked in the Quest airlock. Meir later underwent a retinal, corneal and lens eye exam guided by NASA flight engineer Jack Hathaway, while Adenot tested the EasyMotion-2 suit, which sends electrical impulses and measures muscle contractions.

Hathaway moved cargo into and out of Northrop Grumman's Cygnus XL spacecraft and cleaned the Mochii electron microscope and parts of the MUSES Earth-imaging system. Anil Menon removed Earth-observation equipment in the Kibo laboratory. Roscosmos engineers Anna Kikina and Andrey Fedyaev installed gear to photograph Earth landmarks during the crew's sleep shift; Kikina also measured her blood pressure for a cardiovascular study. Pyotr Dubrov loaded trash into Progress 94, planned to undock September 7, with Progress 96 scheduled to launch September 9 and dock two days later.
