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.

SpaceX is targeting no earlier than Sunday, June 22 for Falcon 9’s launch of Axiom Space’s Axiom Mission 4 (Ax-4) to the International Space Station from Launch Complex 39A (LC-39A) at NASA’s Kennedy Space Center.

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.
