SpaceX announced that it was "standing down" from the Falcon-9 launch to allow time for repairs after a post-static inspection of the rocket's boosters identified a liquid oxygen leak

"Once complete and pending Range availability, we will share a new launch date," SpaceX said in an X post

ISRO Chairman V Narayanan said the liquid oxygen leak was detected in the propulsion bay during a seven-second hot test on the launch pad. The hot test was to validate the performance of the booster stage of Falcon-9 launch vehicle

"The ISRO team discussed with experts at Axiom and SpaceX and it was decided that the leak would be fixed and necessary validation tests conducted before clearing for the launch," Narayanan said

Hence, the Axiom-4 launch slated on June 11, 2025 to send the first Indian Gaganyatri to the International Space Station stands postponed, the ISRO chairman said

Axiom Space spokesperson said that during the post-static fire investigation of the Falcon-9 booster that supports the Axiom-4 mission, SpaceX teams identified a liquid oxygen leak that requires additional work

"SpaceX continues to work closely with Axiom Space and partners," Axiom Space said in a statement

Commander Peggy Whitson, pilot Shukla and specialists Tigor Kapu of Hungary and Slawosz Uznanski-Wisniewski of Poland were slated to embark up on the Axiom-4 mission
