NASA reported on Aug. 14, 2026, that Expedition 75 crew members closed out the week rehearsing Canadarm2 robotics maneuvers and reviewing procedures for a planned spacewalk to replace a space-to-ground antenna. Flight engineers Anil Menon of NASA and Sophie Adenot of ESA were preparing to swap an old high-speed data and communications antenna for a spare on the station's Z1 truss segment, a job described as about six-and-a-half hours in the vacuum of space.

According to the report, Jack Hathaway and station commander Jessica Meir would assist from inside the station, helping the spacewalkers with their suits and operating Canadarm2 with Menon attached. The four astronauts practiced simulated robotics maneuvers on a computer, reviewing the arm's movements, operating modes and safety procedures. The plan called for Menon and Adenot to uninstall the old antenna and temporarily stow it, retrieve a spare from an external platform and install it on Z1 using a tool designed for microgravity connections, then place the old antenna on the platform that held the spare.

NASA said the crew also carried out science and maintenance work that Friday. Menon took exams measuring visual and cognitive adaptation to weightlessness, and Adenot tested the EasyMotion-2 suit, which sends electrical impulses to trigger muscle contractions during exercise. Hathaway inspected hatch seals, Meir cleaned electronics gear and configured the Ultrasound 3 device, while Roscosmos engineers Pyotr Dubrov and Anna Kikina released two spheres of different sizes to study aerodynamic drag. Andrey Fedyaev inspected laptop computers and configured cameras.
