SpaceX has successfully launched four crewmembers to the International Space Station (ISS) in Axiom Space’s privately funded Ax-4 mission.

Retired astronaut Peggy Whitson, America's most experienced space flier, and rookie crewmates from India, Poland and Hungary blasted off on a privately-financed flight to the 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.
