Crew-13 completes final pre-launch checks ahead of Oct. 1 ISS mission

Key points

• Crew-13 is scheduled to launch no earlier than 11:10 a.m. EDT on October 1 from Space Launch Complex 40.
• The four-person crew includes NASA astronauts Jessica Watkins and Luke Delaney, CSA astronaut Joshua Kutryk, and Roscosmos cosmonaut Sergey Teteryatnikov.
• The mission was delayed from September 12 due to an oxidizer leak in the Dragon spacecraft, which was repaired by September 16.
• Crew-13 will join Expedition 75 on the ISS and conduct research on heart disease, Parkinson's disease, and microgravity effects on the human body.
• The current Crew-12 team will depart the ISS shortly after Crew-13 arrives to make way for the new crew.

Background

The Crew-13 mission is part of NASA's Commercial Crew Program, which partners with SpaceX to maintain a continuous human presence on the International Space Station. The mission was originally scheduled for September 12 but was delayed due to an oxidizer leak in the Dragon spacecraft. NASA and SpaceX have been working to resolve the issue and prepare for the new launch date. The mission is also part of a broader effort to prepare for future exploration missions to the Moon and Mars.

How outlets are covering it

Space.com emphasized the visual readiness of the Falcon 9 rocket and Dragon spacecraft on the launch pad, highlighting the static fire test as a key pre-launch milestone. NASA's official release focused on the dry dress rehearsal, detailing the crew's suiting and air leak checks, and the handover process with Crew-12. Spaceflight Now provided background on the crew's arrival in Florida and the delay caused by the oxidizer leak, noting the crew's gratitude for the ground teams' efforts in resolving the issue. WESH highlighted the local connections of the crew, particularly Luke Delaney's Florida roots, and the scientific research planned for the mission, including studies on microgravity and spaceflight-associated neuro-ocular syndrome.

Why it matters

The successful launch of Crew-13 is critical for maintaining a continuous human presence on the International Space Station and advancing scientific research in space. The mission will provide valuable data on the effects of long-duration spaceflight on the human body, which could inform future missions to the Moon and Mars. The partnership between NASA and SpaceX also demonstrates the viability of commercial spaceflight for government missions.

What to watch

Crew-13 is scheduled to launch on October 1, with a target docking time less than nine hours after liftoff. The crew will spend approximately seven months on the ISS, conducting scientific experiments and maintenance. The current Crew-12 team will depart the ISS shortly after Crew-13 arrives, with a splashdown off the coast of California.
