NASA reported on Aug. 7, 2026, that astronauts Jessica Meir and Anil Menon finished a 6-hour, 27-minute spacewalk outside the International Space Station on Aug. 6. They prepared the 3B power channel for a future roll out solar array installation.

Toward the end of that spacewalk, a carbon dioxide sensor on Menon's spacesuit gave an unexpected data reading. Menon reported no other issues, and the sensor returned to normal after the suit was removed. Ground engineers planned to keep evaluating over the following days whether to change suits for the next spacewalk. NASA said it would therefore move the spacewalk to replace a Space-to-Ground antenna to Tuesday, Aug. 18. As of the report, the third planned spacewalk that month remained scheduled for Tuesday, Aug. 25, with more details to come early the following week.

The agency said astronaut Jack Hathaway studied Canadarm2 operations intended to support the next spacewalk and that the spacewalkers for the antenna replacement would soon be named. ESA astronaut Sophie Adenot worked on exercise research, and three Expedition 75 cosmonauts carried out science and maintenance tasks.
