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.

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.

Leaks aboard the International Space Station, as well as on SpaceX's Falcon 9 rocket, delayed Axiom's next private astronaut mission, but the crew now has a target launch date of June 22.
