US EditionFour astronauts launch to the space station as NASA grapples with strange twist in leak issue
- SpaceX and Axiom Space launched the private Axiom Space Mission 4 with four astronauts to the ISS on June 25, 2025, from Kennedy Space Center in Florida.
- The launch was delayed previously due to tests triggered by persistent air leaks in the Russia-controlled Zvezda module since 2019, raising concerns about station-wide air loss.
- NASA and Roscosmos officials investigated the issue, agreeing to lower pressure in the leaking transfer tunnel while sealing efforts appeared to stabilize the module’s pressure.
- Bob Cabana noted in a November meeting that US and Russian teams disagreed on the safety of continued operations because each lacked convincing proof to satisfy the other.
- The Ax-4 team will remain on the ISS for two weeks performing scientific research before heading back, representing a rare privately funded mission amidst ongoing air leak monitoring.

Four Astronauts Launch to International Space Station Despite Concerns Over Air Leak
SpaceX and Houston-based company Axiom Space launched their Axiom Space Mission 4, or Ax-4, from NASA’s Kennedy Space Center in Florida at 2:32 a.m. ET Wednesday after an extended delay had been triggered by tests to assess ongoing air leaks that had been plaguing the International Space Station, CNN reported. The delay of the private mission to send four civilian astronauts to the ISS has exposed a new twist in a lingering — and potentially dan…
