Houston-based Axiom Space launched its fourth crewed mission to the International Space Station (ISS) early Wednesday (June 25), lifting off on a SpaceX Falcon 9 rocket from NASA's Kennedy Space Center (KCS), in Florida. The mission lifted off from KSC's Launch Complex-39A at 2:31 a.m. EDT (0631 GMT).

After several postponed launches, Axiom Space's four private astronauts are finally on their way to the International Space Station.

Over the next 14 days, the Ax-4 crew will carry out around 60 scientific studies and activities representing 31 countries, marking the most research-intensive mission Axiom Space has conducted aboard the space station.
