As reported by NASA on Aug. 26, 2026, Expedition 75 crew members spent that Wednesday cleaning up and relaxing after a spacewalk the previous day to install a high-speed space-to-ground antenna outside the International Space Station. NASA flight engineers Anil Menon and Sophie Adenot of ESA completed the six-hour and 30-minute spacewalk on Tuesday. The crew then cleaned the Quest airlock, refilled spacesuit water tanks and recharged suit batteries, and held a post-spacewalk conference with mission specialists.

At that time, the next spacewalk was scheduled for Tuesday, Sept. 1, with Adenot and Meir planning about six hours and 30 minutes of maintenance. The stated plan called for replacing a visiting spacecraft navigational aid, installing jumper cables for data-relay systems, preparing the Alpha Magnetic Spectrometer for future upgrades and replacing a high-definition camera.

NASA also described human research that week. Menon filled out a questionnaire and collected saliva and hair samples for the RelaxPro investigation on mindfulness and relaxation during long-term spaceflight. Meir assisted as Menon collected and processed a blood sample for the Venus Flow investigation on circulatory health, then took part in an eye exam imaging his retina, cornea and lens. Other crew members carried out maintenance and monitoring tasks, including a 24-hour heart rate session by Roscosmos flight engineer Pyotr Dubrov.
