NASA reported on August 21, 2026, that Expedition 75 crew members spent that Friday preparing for a spacewalk scheduled for 8:35 a.m. EDT on Tuesday. Flight engineers Anil Menon of NASA and Sophie Adenot of ESA (European Space Agency) organized tools, configured tethers and staged equipment inside the Quest airlock.

According to the agency, the spacewalkers planned to install a spare space-to-ground antenna on the Z1 truss segment above the station's Unity module, then move the failed antenna to the same external platform that held the spare. They also planned to replace a retroreflector on the Harmony module's forward port if time allowed. NASA astronauts Jack Hathaway and Jessica Meir were to assist, including with Canadarm2 maneuvers.

The crew also conducted research on exercise techniques for muscle and bone health in microgravity, and flight engineer Andrey Fedyaev wore an acoustic sensor to help study how weightlessness affects the respiratory system. Other crew members performed maintenance and Earth observation work. The report is a snapshot as of its publication date.
