NASA Delays Crew-7 Launch Until Saturday

NASA and SpaceX are targeting 3:27 a.m. EDT Saturday, Aug. 26, for launch of the agency’s Crew-7 mission to the International Space Station.

Mission managers met on Thursday to discuss the status toward final readiness for a Friday launch opportunity. After performing an extra data review, teams decided to take additional time to reconfirm required factors of safety and operational margin on one of the Dragon spacecraft’s environmental control and life support system (ECLSS) components.

The new launch date provides teams additional time to complete the analysis and thoroughly review the necessary data ahead of launch. All ECLSS valves on the Crew-7 and Crew-6 Dragon spacecraft are performing normally, and performed as expected in all preflight testing. Safety continues to be the team’s top priority.

The Falcon 9 rocket and Dragon spacecraft remain healthy as teams complete and discuss the final results of this additional analysis, and the crew is ready to fly when the entire team is ready.

For a launch on Saturday, the U.S. Space Force 45th Weather Squadron predicts a 95% chance of favorable weather conditions at the launch pad for liftoff based on Falcon 9 Crew Dragon launch weather criteria.

The Dragon spacecraft carrying NASA astronaut Jasmin Moghbeli, commander; ESA (European Space Agency) astronaut Andreas Mogensen, pilot; and mission specialists JAXA (Japan Aerospace Exploration Agency) astronaut Satoshi Furukawa, and Roscosmos cosmonaut Konstantin Borisov will launch atop the SpaceX Falcon 9 rocket from Launch Complex 39A at NASA’s Kennedy Space Center in Florida.

The Dragon spacecraft, named Endurance, is scheduled to dock to the space station at 8:50 a.m. Sunday, Aug. 27.

Live coverage of Crew-7 activities begins at 11:30 p.m., Friday, Aug. 25, on NASA Television and the agency’s website.
