NASA reported on Aug. 12, 2026, that preparations were under way aboard the International Space Station for a spacewalk planned for Tuesday, Aug. 18. According to the agency, flight engineers Anil Menon of NASA and Sophie Adenot of ESA were to work outside the station for about six-and-a-half hours to replace a high-speed data and communications antenna.

Menon, Adenot and NASA flight engineer Jack Hathaway reviewed the steps for removing a failed space-to-ground antenna, stowing it on an external platform and installing a spare on the station’s Z1 truss segment. Hathaway and NASA commander Jessica Meir were slated to help the spacewalkers in and out of their spacesuits and to operate the Canadarm2 robotic arm during the excursion.

The seven-member Expedition 75 crew also practiced emergency roles with mission controllers on Earth, using tablets to review procedures for scenarios such as a pressure leak, chemical leak or fire. Roscosmos flight engineers conducted inspections and maintenance tasks, including a photographic inspection of module windows and oxygen generator support.
