June 10 (UPI) -- The Axiom-4 mission launch, the fourth private astronaut mission to the International Space Station, was canceled for a second time Tuesday after SpaceX detected a liquid oxygen leak in its Falcon 9 rocket.
SpaceX announced Tuesday night in a post on X that it was "standing down" from Wednesday's launch of Axiom-4.
"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."
