In a report dated Aug. 27, 2026, NASA said preparations were ongoing for a spacewalk planned for 8:30 a.m. EDT on Tuesday, Sept. 1. Flight engineer Sophie Adenot of ESA and station commander Jessica Meir of NASA were studying procedures for the roughly six-and-a-half-hour excursion, which was to include replacing a spacecraft navigational aid, preparing a cosmic particle detector for future upgrades and installing jumper cables to boost data-relay systems. The astronauts reviewed procedures with NASA flight engineers Anil Menon and Jack Hathaway.

The Expedition 75 crew also continued biomedical research. Meir scanned Menon's jugular veins with the Ultrasound 3 device and measured his blood pressure while researchers monitored in real time; Adenot exercised in the EasyMotion-2 suit, which sends electrical impulses to trigger muscle contractions; and Hathaway inventoried medical supply kits in the Human Research Facility-1 and -2 racks. Cosmonaut Anna Kikina completed a 24-hour monitoring session, and Meir later scanned Andrey Fedyaev's veins.

NASA reported that Northrop Grumman's Cygnus XL cargo spacecraft fired its thrusters for 20 minutes, 43 seconds while berthed to the Unity module, raising the station's orbit to the altitude needed for the rendezvous and docking of the Progress 96 resupply ship, due to launch in early September. Cosmonaut Pyotr Dubrov worked on life support maintenance.
