The tape of U.S. spacewalk 99 is the object. Not a second hull report. Where to watch. What the cameras were pointed at. NASA astronaut Jessica Meir and ESA astronaut Sophie Adenot went outside the International Space Station on Tuesday, 1 September 2026. NASA's own advance notice said live coverage would begin at 7 a.m. Eastern. The walk itself started when the suits went to battery power — Space.com and ESA put egress around 8:40 a.m. Eastern, about 12:40 UTC — and the station blog closed the clock at 3:29 p.m. Eastern after 6 hours and 49 minutes.
