KENNEDY SPACE CENTER, FL – Everything had been looking good for a liftoff of the Axiom Mission 4 carrying 4 astronauts to the International Space Station at 8 AM ET on Wednesday, June 11, until SpaceX engineers discovered a LOX leak in the first stage of the Falcon 9 rocket – upon further review of data from a static fire test of the first stage Merlin 1D engines  that was conducted on Sunday afternoon June 8.

“Standing down from tomorrow’s Falcon 9 launch of Ax-4 to the @Space_Station to allow additional time for SpaceX teams to repair the LOx leak identified during post static fire booster inspections. Once complete – and pending Range availability – we will share a new launch date,” SpaceX tweeted.

NASA, Axiom Space, and SpaceX decided to standing down from the launch opportunity on Wednesday, June 11, of Axiom Mission 4 to the International Space Station “to allow additional time for SpaceX teams to repair a liquid oxygen leak identified during post-static fire Falcon 9 rocket inspections,” NASA announced in a message and a blog post late on June 10.

“A new launch date for the fourth private astronaut mission will be provided once repair work is complete, pending range availability.”
