NASA reported on September 8, 2026, that the Expedition 75 crew aboard the International Space Station focused that Tuesday on astronaut health research and photography of the Moon and Earth, while continuing life support maintenance after a cargo spacecraft departed the day before.

Station commander Jessica Meir of NASA assisted ESA flight engineer Sophie Adenot in the Columbus laboratory module during the PhysioTool experiment, which monitors blood flow, mental condition and sleep quality. According to the report, Adenot measured her blood pressure and completed cognitive tasks on a computer, after which NASA flight engineer Jack Hathaway measured her muscles and tendons as part of the Myotones investigation. Meir wore a smartwatch for the RelaxPro sleep study and later used a visual field device to measure her peripheral vision.

Hathaway replaced filters in the Destiny and Harmony modules, and Anil Menon of NASA stowed spacewalking gear and spacesuit batteries, configured a free-flying camera and inspected the exercise device before photographing the Moon from the cupola. Roscosmos flight engineers Andrey Fedyaev, Anna Kikina and Pyotr Dubrov carried out balance tests, biomedical equipment checks and automated Earth imagery. NASA stated that the Progress 94 cargo spacecraft undocked on Monday and reentered Earth's atmosphere less than four hours later over the South Pacific Ocean.
