Axiom Mission 4 (Ax‑4) is a planned private spaceflight to the International Space Station (ISS) operated by Axiom Space in partnership with SpaceX and NASA. It will use a SpaceX Falcon 9 Block 5 rocket to place Crew Dragon C213 into low Earth orbit. This will be the maiden flight of the C213 spacecraft, the fifth and final Crew Dragon to be built.
The flight was scheduled to lift off from Launch Complex 39A at the Kennedy Space Center on 11 June 2025, but the first attempt was scrubbed due to a liquid oxygen leak. The next attempt was postponed until 22 June 2025 7:42 am UTC (3:42 am EDT, 1:12 pm IST, 9:42 am CET) due to an unrelated leak in the Zvezda service module of the ISS.
