NASA reported on Aug. 19, 2026 that Expedition 75 crew members were cleaning up after a spacewalk that saw two astronauts remove an antenna outside the International Space Station. Flight engineers Anil Menon of NASA and Sophie Adenot of ESA had completed a six-hour and 23-minute spacewalk the previous day, disconnecting a failed high-speed antenna and securing it with a long-duration tie down on the station's Z1 truss segment. NASA said a spare antenna would be installed in its place during a future spacewalk.

According to the agency's account, Adenot spent part of the day inside the Quest airlock refilling spacesuit water tanks, later joined by station commander Jessica Meir to power down suit components, remove batteries and stow hardware. Menon conducted blood tests and vein scans with assistance from Meir and Jack Hathaway as part of the Venus Flow investigation into space-caused blood-flow risks.

The station's three Roscosmos cosmonauts continued their own science and maintenance. Andrey Fedyaev measured his blood pressure and photographed North American lakes, Anna Kikina tested artificial intelligence tools for transcribing crew reports, and Pyotr Dubrov completed a scheduled fitness assessment on a treadmill.
