Space station leak concerns will delay visit by astronauts from India, Poland and Hungary
- NASA indefinitely delayed the four-person Axiom-4 spaceflight to the International Space Station from Florida on June 12, 2025.
- The delay followed escalating concerns over a persistent air leak in the aging Russian Zvezda service module, first noticed in 2019.
- Cosmonauts inspected and sealed leak points in the Zvezda module, leading to a currently stable pressure, while SpaceX also faced a liquid oxygen leak in the Falcon 9 rocket.
- The leak rate remained steady at approximately 1 to 2 pounds per day, and NASA reported that cosmonauts inspected the inside of the pressurized module, applied seals to several identified spots, and checked the ongoing rate of leakage.
- The delay provides NASA, Roscosmos, and Axiom Space extra time to assess safety and determine if further repairs are needed before resuming commercial missions.

Axiom-4 mission: Leak on ISS, not oxygen leak from launch vehicle behind indefinite delay
The Axiom-4 space mission has been indefinitely delayed due to pressurization issues in the ISS. Indian astronaut Shubhanshu Shukla, set to be the second in space, will wait for a revised launch schedule post technical reviews by NASA and ISRO.
Shubhanshu Shukla's Axiom Mission 4 postponed again, over Space Station and Rocket technical issues
India’s hopes of returning to human spaceflight after 41 years have hit another roadblock. The launch of Axiom Mission 4, featuring Indian astronaut Shubhanshu Shukla, has been postponed again, this time due to technical issues related to both the International Space Station (ISS) and the SpaceX Falcon 9 rocket. Originally scheduled for June 11, 2025, the mission was set to make headlines globally, as Shukla would become one of the few Indians t…
The launch was postponed on Wednesday due to a rocket leak, and the recently damaged module called Zvezda is also being inspected more closely due to the slippage.
