The private Ax-4 mission was supposed to launch to the International Space Station (ISS) from Florida’s Kennedy Space Center on June 10, but inclement weather in the ascent corridor forced the mission team to call off the effort. A plan to launch 24 hours later was also ditched following the discovery of a liquid oxygen leak on the rocket.

SpaceX has reset the countdown clock for its next human spaceflight targeting an early Sunday morning launch of the private Axiom Space Ax-4 mission.

Officials for NASA, Axiom Space and SpaceX will attempt to launch the Axiom-4 mission as soon as Sunday after a Falcon 9 rocket leak scrubbed the June 11 mission launch.
