This Is When Axiom-4 Mission Carrying Shubhashu Shukla Will Be Launched

NASA, Axiom Space, and SpaceX are targeting no earlier than June 19 for the fourth private astronaut mission to the International Space Station. The Axiom Mission 4 launch was postponed from June 12 as the agency continued evaluating repairs made to a recent leak on the ISS. The small leaks, located in the Zvezda service module’s aft section, had been under observation for years. Now, following a recent repair, the pressure in the module’s transfer tunnel has remained stable, indicating either successful sealing of leaks or compensatory airflow from other station compartments.

NASA Targets June 19 for Axiom-4 Launch as ISS Pressure Holds and Falcon 9 Passes Final Tests

As per a NASA update, while the stable pressure offers promise, teams are still evaluating whether it reflects a successful seal or airflow leakage across the hatch from the main station. Monitoring pressure changes over time is expected to provide clearer insights. Adjustments in launch schedules are considered routine by NASA and its international partners, particularly when onboard station operations require urgent prioritisation.

Progress on the evaluation front has allowed the review of new launch windows. The earlier hold was further compounded by a liquid oxygen leak discovered during post-static fire inspections of the SpaceX Falcon 9 rocket. SpaceX successfully performed a wet dress rehearsal after repairs, validating that the rocket is good to go for launch from the Kennedy Space Centre‘s Launch Complex 39A.

The mission will be commanded by Peggy Whitson, an experienced NASA astronaut who is Axiom Space’s director of human spaceflight. India’s Shubhanshu Shukla of ISRO will pilot the mission. The mission specialists include Polish ESA astronaut Sławosz Uznański-Wiśniewski and Hungarian astronaut Tibor Kapu. The mission represents an extension of Axiom’s increasingly prominent position in commercial human spaceflight.

The new launch date for the Axiom-4 mission is currently targeted for June 19, 2025. SpaceX has verified that all of the technical issues that caused the first delay have been resolved. Further updates will be released as NASA and its partners finalise operational assessments, as shared by Union Minister Dr. Jitendra Singh in an official statement.
