SpaceX Crew-6 Launch

NASA’s Crew-6 mission to the International Space Station (ISS) is scheduled to launch on 2023-03-02 at 05:34 UTC. The mission will take four crew, two from NASA, one from Russia’s Roscosmos, and one from the United Arab Emirates (UAE) space agency, to the station for a six month stay. They will fly to the ISS in Crew Dragon vehicle Endeavour, which previously flew to and from the ISS on the Demo-2, Crew-2, and Axiom Space Ax-1 missions. The first stage booster, B1078, is new and will be making its first flight. Weather is forecast as 95% favourable for launch.

Roscosmos cosmonaut Andrey Fedyaev was scheduled to fly to the ISS on Soyuz MS-23, which was re-purposed as a replacement for MS-22 which sprung a coolant leak while docked to the ISS. He was moved up to the Crew-6 flight as part of the seat swap agreement between NASA and Roscosmos. UAE astronaut Sultan Al Neyadi is flying under an agreement between Axiom Space and Mohammed bin Rashid Space Centre, using a seat Axiom traded to NASA on its Axiom-1 mission to fly a NASA astronaut to the station.

Here is a pre-flight preview from Everyday Astronaut.

This is the NASA SpaceX Crew-6 Launch Readiness Review media teleconference, held on the evening of 2023-02-25 Florida time.


The countdown was halted and the launch attempt scrubbed for the day at two minutes and twenty-five seconds before the scheduled launch due to a problem with ground equipment involved in loading the triethylaluminium-triethylborane mixture (TEA-TEB) pyrophoric “starter fluid” which is used to ignite the booster’s Merlin engines. The launch window to the International Space Station is instantaneous, so any delay in the countdown requires a stand-down.



The next launch attempt is now set for 2023-03-02 at 05:34 UTC. I have updated the main post accordingly.

The launch, booster landing, and orbital insertion were completely successful. Here is the NASA/SpaceX post-launch news conference.


Docking of the Crew-6 Crew Dragon Endeavour with the International Space Station is scheduled for 2023-03-03 at 06:17 UTC. The live Webcast will start around an hour and half before the planned docking time.
