Until the air leak detected on the ISS' Russian segment is resolved, NASA has opted not to send any other people to dock at the station.

The Axiom-4 mission launch, the fourth private astronaut mission to the International Space Station, was canceled Tuesday night after SpaceX detected a liquid oxygen leak in its Falcon 9 rocket.

An ongoing leak on the Russian side of the International Space Station has prompted an indefinite postponement of a planned human spaceflight from Kennedy Space Center, according to NASA.
