After several postponed launches, Axiom Space's four private astronauts are finally on their way to the International Space Station (ISS). The multinational crew lifted off successfully aboard a SpaceX Dragon launched by a Falcon 9 rocket from NASA's Kennedy Space Center's Launch Complex 39A in Florida early Wednesday at 2:31 a.

A Russia-controlled module on the space station has been leaking for years. Now, operators are working to figure out if the issue is affecting the entire station.

SpaceX launched a Crew Dragon spacecraft on a private astronaut mission to the International Space Station June 25 after weeks of delays.
