NASA reported on Sept. 9, 2026, that Expedition 75 crew members aboard the International Space Station carried out vein scans, ultra-hot physics work and Earth observations that Wednesday, alongside spacesuit and life support maintenance.

NASA astronauts Jessica Meir and Anil Menon joined Roscosmos cosmonauts Anna Kikina and Pyotr Dubrov in the Columbus laboratory module for scheduled vein scans using the Ultrasound 3 device. Meir acted as crew medical officer, operating the device with real-time guidance from doctors on the ground, and scanned Menon, then Kikina, then Dubrov. NASA said the insights would help promote healthy crews on long-duration missions to the Moon, Mars and beyond.

ESA flight engineer Sophie Adenot cleaned the Electrostatic Levitation Furnace inside the Kibo laboratory module, removing samples and cleaning components before installing new samples. NASA said the facility heats materials to over 2,000 degrees Celsius using lasers. Menon also swapped out a radio communications unit on a spacesuit in the Quest airlock, and NASA flight engineer Jack Hathaway continued replacing filters in Quest and the Unity and Tranquility modules.
