NASA reported on Aug. 4, 2026, that the Expedition 75 crew continued preparations for a spacewalk planned for that Thursday, Aug. 6, to augment the International Space Station's power system. NASA astronauts Jessica Meir, the station commander, and Anil Menon were to begin the roughly seven-hour spacewalk at 8:35 a.m. EDT, building a modification kit on the Starboard 6 truss segment where a roll-out solar array was to be installed later in 2026. NASA's report described the plan as of that date.

Flight engineers Jack Hathaway of NASA and Sophie Adenot of ESA reviewed procedures and were to assist the spacewalkers with their suits. Hathaway also tested the European Enhanced Exploration Exercise Device and installed ClimCam hardware, which analyzes real-time Earth imagery for weather and climate monitoring and was to be robotically placed outside the station. Roscosmos engineers Andrey Fedyaev and Pyotr Dubrov installed an imaging device in the Zvezda service module, NASA said.

NASA astronaut Chris Williams, who ended a 241-day mission on July 26, 2026, spoke at a post-flight news conference in Houston on Aug. 4.
