SpaceX Crew-13 Launch for NASA Set for October 1 After Dragon Leak Delay

SpaceX and NASA are preparing to send four astronauts to the International Space Station on October 1, following a delay caused by a propulsion-system leak aboard the mission’s Crew Dragon spacecraft.

The mission, known as Crew-13, is now targeting liftoff at 11:10 a.m. EDT on Thursday, October 1, from Space Launch Complex 40 at Cape Canaveral Space Force Station in Florida. NASA lists October 1 as the earliest available launch opportunity for the mission.

The new launch target comes nearly three weeks after the original September 12 date was removed from the schedule. NASA and SpaceX postponed the flight after teams detected an oxidizer leak in the propulsion system of the Dragon spacecraft during prelaunch preparations.

The issue required additional inspections, testing and repair work before the spacecraft could be cleared for another crewed launch attempt.

Dragon Leak Forced the Original Delay

Crew-13 was originally scheduled to launch in September, but preparations changed after engineers discovered an oxidizer leak on the Dragon spacecraft.

The propulsion system is essential to the spacecraft’s ability to maneuver in orbit and perform other critical operations. Because Crew-13 will carry four people to the space station, NASA and SpaceX have followed additional testing and review procedures before setting a new launch target.

NASA and SpaceX later confirmed that teams had replaced an oxidizer valve associated with the leak. Following the repair, engineers continued reviewing the spacecraft and preparing it for flight.

The delay illustrates how even relatively late-stage problems can affect a crewed spaceflight schedule. Human missions require extensive verification because spacecraft systems must meet strict safety requirements before astronauts can launch.

By September 22, NASA said teams were moving into final preparations for the October 1 opportunity. Those activities include additional reviews of the Dragon spacecraft, Falcon 9 rocket, space station and crew.

Four Astronauts Will Fly on Crew-13

Crew-13 will carry four astronauts representing NASA, the Canadian Space Agency and Roscosmos.

NASA astronaut Jessica Watkins will serve as commander, while NASA astronaut Luke Delaney will be the mission’s pilot. Canadian Space Agency astronaut Joshua Kutryk and Roscosmos cosmonaut Sergey Teteryatnikov will serve as mission specialists.

The crew has spent months completing training for the mission, including work with the Dragon spacecraft and procedures designed to prepare them for life and operations aboard the International Space Station.

The astronauts also entered routine prelaunch quarantine in September as part of the final preparations. NASA said the quarantine period limits in-person contact and includes medical screening for people who need to interact with the crew.

Their mission will support the ongoing scientific and operational work aboard the International Space Station.

Falcon 9 Will Launch the Crew Dragon

Crew-13 will launch on a SpaceX Falcon 9 rocket, with the Crew Dragon spacecraft carrying the astronauts into low Earth orbit.

The flight is part of NASA’s Commercial Crew Program, which uses commercial spacecraft and launch vehicles to transport astronauts to and from the International Space Station.

NASA describes Crew-13 as the 13th crew rotation mission in SpaceX’s human transportation system and the company’s 14th Dragon flight carrying astronauts to the station, including the Demo-2 test mission.

The October launch will take place from Space Launch Complex 40 at Cape Canaveral Space Force Station. SpaceX has increasingly used the Florida facility for crew and cargo operations as launch infrastructure at the nearby Kennedy Space Center continues to evolve.

After reaching orbit, Dragon is expected to travel toward the International Space Station for docking. Current plans call for the spacecraft to arrive at the station later on October 1, assuming the launch and orbital operations proceed as scheduled.

Crew-13 Will Join the International Space Station

Once they arrive, the four Crew-13 astronauts will join the station’s existing Expedition 75 crew.

Their arrival is also important for the planned rotation of personnel aboard the orbital laboratory. Crew-13 will eventually take over from the astronauts currently preparing to return to Earth.

NASA has said the station’s current residents are continuing scientific research, maintenance and other activities while the replacement crew prepares for launch.

Crew-13 is expected to spend roughly seven months in orbit, during which the astronauts will conduct experiments, maintain station systems and participate in other activities supporting NASA’s long-term human spaceflight program.

The mission will include both routine station operations and scientific work intended to improve understanding of living and working in microgravity.

October 1 Target Still Depends on Final Reviews

Although October 1 is now the target date, NASA continues to describe it as the earliest launch opportunity rather than an unconditional launch date.

Teams still have to complete final checks and confirm that the rocket, spacecraft, space station and crew are ready. Weather and technical conditions can also affect launch schedules.

That cautious approach is standard for human spaceflight, where a launch can be postponed if engineers identify a problem or if conditions are not suitable.

For now, however, the focus is on October 1.

After the earlier delay, the new target gives SpaceX and NASA a clear timetable for completing the final stages of Crew-13 preparation. The successful repair of the Dragon propulsion-system leak has allowed the mission to move forward toward its next major milestone.

If the launch proceeds as planned, Crew-13 will begin another chapter in the continuing partnership between NASA and SpaceX, sending four astronauts aboard a Falcon 9 and Crew Dragon toward the International Space Station.

The mission also demonstrates the demanding nature of crewed spaceflight. Even after months of training and preparation, a single spacecraft issue can force a launch date to move while engineers investigate, repair and verify the system.

For NASA and SpaceX, the priority remains the same: ensuring Crew-13 is ready before the astronauts leave Earth.
