June 18 (UPI) -- 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.
The Axiom-4 mission on June 22 would be the fourth private astronaut mission to the International Space Station, according to NASA.
NASA officials have been evaluating ISS operations following a recent repair service to the aft-most segment of the ISS's Zvezda service module.
A liquid oxygen leak caused SpaceX to scrub the Axiom-4 mission's June 11 launch after discovering it a day earlier.
