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.

An active investigation into a leak repair on the International Space Station continues to cause NASA to shift the launch of four private astronauts on the Axiom Space Mission 4.
