(Image credit: SpaceX) The crew of Houston-based Axiom Space's next launch to the space station is back on the board. Axiom's fourth astronaut mission (Ax-4) to the International Space Station (ISS) has a new launch date. The crew of four will liftoff aboard a SpaceX Crew Dragon spacecraft atop a Falcon 9 rocket no earlier than June 25, NASA announced Monday evening (June 23). Liftoff is scheduled for 2:31 a.m. EDT (0631 GMT) from Launch Complex-39A, at NASA's Kennedy Space Center, in Florida.. The launch had been indefinitely delayed last week due to a leak detected aboard the ISS. No update was given about that leak in NASA's announcement of the new launch date. You may like
