Houston-based Axiom Space launched its fourth crewed mission to the International Space Station (ISS) overnight, lifting off on a SpaceX Falcon 9 rocket from NASA's Kennedy Space Center (KCS), in Florida. The mission got underway early Wednesday, lifting off from KSC's Launch Complex-39A at 2:31 a.m. EDT (0631 GMT).

A SpaceX vehicle carrying four astronauts on a private mission for Axiom Space is on its way to the International Space Station.

After a series of delays from weather to rocket engines to a leak on the International Space Station, NASA has cleared the way for SpaceX to launch the Axiom Space Ax-4 crew on the Space Coast.
