NASA and SpaceX postponed the launch of the Crew-13 mission to the International Space Station after detecting an oxidizer leak on the Dragon spacecraft’s propulsion system during routine prelaunch processing, according to official agency announcements. Joint engineering teams from both organizations are conducting additional testing and reviewing data to determine whether the spacecraft requires further rework before receiving a new target flight date.
Propulsion System Leak Delays International Space Station Mission
According to NASA and SpaceX, the technical issue centers on the Dragon spacecraft’s propulsion system, specifically involving an oxidizer leak. Technicians and engineers are evaluating the exact scope of the problem to ensure flight readiness before scheduling a new launch attempt.
Prior to the delay, the mission had been targeted for liftoff on September 12. The flight will utilize a SpaceX Falcon 9 rocket lifting off from Space Launch Complex 40 at Cape Canaveral Space Force Station in Florida, according to mission schedules. Once teams finish reviewing testing data and complete any required component repairs, officials will announce a revised flight schedule.
Crew-13 Roster and Expedition 75 Integration
The four-person international crew for the flight remains unchanged despite the schedule adjustment. NASA astronaut Jessica Watkins serves as the spacecraft commander, partnered with NASA astronaut Luke Delaney as the pilot, according to mission documentation. Canadian Space Agency astronaut Joshua Kutryk and Roscosmos cosmonaut Sergey Teteryatnikov round out the roster as mission specialists.
Upon arriving at the orbiting laboratory, the Crew-13 members will integrate directly into the ongoing operations of Expedition 75. Data provided by NASA indicates that this flight represents the 14th crewed journey of a Crew Dragon spacecraft—which incorporates the Demo-2 test flight—while also standing as the 13th crew rotation mission that SpaceX has managed for NASA.
Did you know?
Agency records show that the upcoming Crew-13 mission will be the initial spaceflight for Canadian Space Agency astronaut Joshua Kutryk, establishing him as the fourth Canadian to undertake a long-duration stay on the International Space Station and the first Canadian to reach the station via NASA’s Commercial Crew Programme.
Preflight Quarantine and Launch Operations
Launch preparations at Cape Canaveral Space Force Station involve strict health safeguards for the flight crew. According to NASA, the astronauts are scheduled to enter a formal quarantine period approximately two weeks prior to liftoff at the Johnson Space Center in Houston once a new target launch date is officially established.
Space Launch Complex 40 serves as the primary departure point for the mission, utilizing a Falcon 9 rocket paired with the Crew Dragon capsule. Joint NASA and SpaceX flight readiness reviews will dictate the final clearance to proceed once the propulsion system data review concludes.
