Minister of State for Science and Technology Dr Jitendra Singh has said that the launch of Axiom Mission 4, carrying India’s astronaut Shubhanshu Shukla to the International Space Station, is postponed. In a social media post, Dr Singh said a liquid oxygen leak was detected during a seven-second hot test of Falcon 9’s booster. He said that after a joint review by ISRO, Axiom and SpaceX teams, it was decided to rectify the issue and revalidate before liftoff.
