NASA and SpaceX delay Crew-13 launch after Dragon oxidizer leak
NASA and SpaceX pushed back Crew-13's ISS launch after finding an oxidizer leak in Dragon's propulsion system during processing.
what happened
NASA said Aug. 29 that it and SpaceX are adjusting the launch date for the Crew-13 mission to the International Space Station after an oxidizer leak was detected on the Dragon spacecraft's propulsion system during standard prelaunch processing, per NASA's own blog. The mission, previously targeted for Sept. 12 from Space Launch Complex 40 at Cape Canaveral, will carry NASA's Jessica Watkins and Luke Delaney, CSA's Joshua Kutryk, and Roscosmos's Sergey Teteryatnikov to Expedition 75; NASA and SpaceX are running additional tests and data review before setting a new target date.
why it matters
A propulsion leak caught during routine ground processing, not in flight, is a normal part of human-rated hardware turnaround, but it pushes back the next ISS crew rotation and adds pressure to Dragon's shared schedule as SpaceX juggles crew, cargo, and commercial missions on the same vehicle line. It's a reminder that Commercial Crew's cadence still depends on catching hardware issues before launch, not after.
