Following numerous delays and scrubbed liftoffs, NASA, SpaceX and Axiom Space successfully launched their Axiom-4 mission early Wednesday, sending four astronauts in what is the fourth private commercial mission 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.
