“Concern about a small but persistent air leak in a Russian compartment of the International Space Station has prompted NASA and Axiom Space to indefinitely delay this week’s launch of a commercial flight to the orbiting outpost, officials said Thursday. The privately-financed Axiom-4 crew … originally planned to take off Tuesday. But the flight was delayed to the end of the week, first by high winds in the off-shore emergency splashdown zone and then by an oxygen leak in their Falcon 9 rocket’s first stage. SpaceX tentatively targeted Thursday and then Friday for launch, with Saturday and Sunday available if needed. But during SpaceX troubleshooting to find and fix the rocket’s propellant leak, NASA engineers decided they needed more time to assess recent efforts to plug an air leak aboard the International Space Station in a Russian vestibule known as the PrK.” (06/12/25)
