Expedition 75 crew members aboard the International Space Station worked on circuit board soldering, spacesuit maintenance and cargo mission preparations on Thursday, Sept. 17, 2026, NASA reported that day. The schedule also included cardiac research, virtual reality tests and housekeeping.

NASA flight engineer Anil Menon continued the MIYOKA experiment, using a lead-free soldering technique on circuit board components intended for return to Earth and comparison with identical ground-soldered samples. The agency said results may inform future crews travelling to the Moon, Mars and beyond, reducing reliance on resupply missions. Station commander Jessica Meir and flight engineer Jack Hathaway inspected and checked spacesuit cooling systems in the Quest airlock. Sophie Adenot of ESA took part in the RelaxPro investigation on stress and sleep, and Roscosmos flight engineers Pyotr Dubrov and Anna Kikina tested the Zvezda module's remote-control rendezvous unit ahead of Progress 96's planned automatic docking at the Poisk module.

According to the report, Progress 96 launched from Kazakhstan on Wednesday carrying 2.8 tons of food, fuel and supplies. Dubrov and Kikina also measured blood pressure to document microgravity's effects on the microcirculatory system and used virtual reality headsets for the Teledroid investigation.
