The much-awaited multi-nation space mission Axiom-4 has been delayed due to a technical issue. A liquid oxygen (LOX) leak was detected during a 7-second hot test of the Falcon 9 booster, prompting a joint review by ISRO, Axiom, and SpaceX teams. However, with the June 11 launch postponed, all eyes on the next date and time for the Space mission.
Sharing an update about the issue, SpaceX said, “Standing down from tomorrow’s Falcon 9 launch of Ax-4 to the Space Station to allow additional time for SpaceX teams to repair the LOx leak identified during post static fire booster inspections. Once complete – and pending Range availability – we will share a new launch date.”
Indian Space Research Organisation (ISRO) said that it has been decided to correct the leak and carry out necessary validation test before clearing for the launch. “Postponement of Axiom 04 mission slated for launch on 11th June 2025 for sending first Indian Gaganyatri to ISS. As part of launch vehicle preparation to validate the performance of booster stage of Falcon 9 launch vehicle, seven second of hot test was carried out on the launch pad. It is understood that LOX leakage was detected in the propulsion bay during the test. Based on the discussion on this topic by ISRO team with the experts of Axiom and SpaceX it has been decided to correct the leak and carry out necessary validation test before clearing for the launch. Hence the launch of Axiom 04 slated for 11th June 2025 for sending first Indian Gaganyatri to ISS is postponed,” said ISRO on X.
The Axiom-4 mission crew includes members from India, Poland, and Hungary, marking each nation’s first mission to the space station in history and the second government-sponsored human spaceflight mission in over 40 years, according to Axiom Space.
Group Captain Shubhanshu Shukla will be India’s second national astronaut to go to space since 1984. Group Captain Shubhanshu Shukla is part of Axiom Space’s fourth private astronaut mission (Ax-4), marking a historic moment for India’s space collaboration with NASA.
Slawosz Uznanski, European Space Agency (ESA) project astronaut, will be the second Polish astronaut since 1978. Tibor Kapu will be the second national Hungarian astronaut since 1980. Peggy Whitson will command her second commercial human spaceflight mission, adding to her standing record for the longest cumulative time in space by an American astronaut.
