The launch of the Axiom-4 (Ax-4) mission, scheduled for June 11, to the International Space Station (ISS) has been postponed again, SpaceX confirmed in a post on X. The delay comes after a liquid oxygen (LOx) leak was detected during post-static fire booster inspections. The mission is set to send Indian astronaut Group Captain Shubhanshu Shukla to the ISS.
