Space Station Leak Delays Mission, Raises Safety Concerns | JQJO

A private astronaut mission, Axiom Space Mission 4 (Ax-4), launched despite a concerning air leak on the International Space Station (ISS). The leak, originating from a Russian module, had seemingly stopped, raising fears of a new, internal leak drawing air from the rest of the station. NASA and Roscosmos investigated, lowering pressure in the affected tunnel. The Ax-4 mission, carrying four astronauts including a former NASA astronaut and three spaceflight novices, will conduct experiments for about two weeks. The cause and extent of the leak remain unclear, impacting future mission planning.
