NASA and SpaceX are adjusting the launch date for the Crew-13 mission to the International Space Station to address an oxidizer leak on the Dragon spacecraft's propulsion system, according to a NASA report published Aug. 29, 2026. The leak was detected during standard prelaunch spacecraft processing. Joint NASA and SpaceX teams were performing additional tests and data review and planned to complete any necessary rework before launch. A new target date would be announced once available.

NASA astronauts Jessica Watkins and Luke Delaney are to serve as spacecraft commander and pilot. They would be joined by CSA astronaut Joshua Kutryk and Roscosmos cosmonaut Sergey Teteryatnikov as mission specialists. After arriving, the crew would become members of the station's Expedition 75. The crew was expected to enter quarantine about two weeks before flight from Johnson Space Center in Houston, and the mission was planned to lift off aboard Dragon on a Falcon 9 rocket from Space Launch Complex 40 at Cape Canaveral Space Force Station in Florida.

As of the report, no replacement launch date had been set.
