NASA has postponed the planned mid-September launch of the Crew-13 mission to the International Space Station (ISS), which includes Roscosmos cosmonaut Sergey Teteryatnikov, the US space agency said.

“NASA and SpaceX are adjusting the launch date for the agency’s Crew-13 mission to the International Space Station to address an oxidizer leak on Dragon’s propulsion system which was detected during standard prelaunch spacecraft processing. Joint NASA and SpaceX teams are performing additional tests and data review and will complete any necessary rework prior to launch. A new target date will be announced once available,” NASA said on its website.
