Washington D.C. [US], June 11 (ANI): The launch of the Axiom-4 (Ax-4) mission to the International Space Station (ISS) has been postponed after SpaceX detected a liquid oxygen (LOx) leak during a routine post-static fire booster inspection. The mission, originally scheduled for June 11, 2025, was set to carry astronauts from India, Poland, and Hungary, including India’s first Gaganyatri to the ISS.
Announcing the delay, SpaceX stated on X (formerly Twitter):
“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.”
Following SpaceX’s announcement, the Indian Space Research Organisation (ISRO) confirmed the mission delay, which was to mark India’s return to human spaceflight after more than four decades.
In an official statement, ISRO said:
“Postponement of Axiom-04 mission slated for launch on 11th June 2025 for sending first Indian Gaganyatri to ISS. A seven-second hot test was conducted on the launch pad as part of booster stage validation. It is understood that LOx leakage was detected in the propulsion bay during the test. After detailed discussions between ISRO, Axiom, and SpaceX experts, it was decided to correct the leak and perform additional validation before clearing the mission for launch.”
A Mission of Historic Significance
Despite the setback, the Ax-4 mission remains a milestone in international space cooperation. This mission includes the first astronauts from India, Poland, and Hungary to fly to the ISS, and marks only the second government-sponsored spaceflight for each of these nations in over 40 years.
India’s Group Captain Shubhanshu Shukla is set to become the country’s second astronaut to travel to space, following Rakesh Sharma’s historic flight in 1984. Representing Poland is Slawosz Uznanski, a European Space Agency (ESA) astronaut, and from Hungary, Tibor Kapu. The mission will be commanded by veteran astronaut Peggy Whitson, who holds the U.S. record for the longest cumulative time in space.
According to Axiom Space, the Ax-4 mission will be the second commercial spaceflight made up of government- and ESA-sponsored astronauts and symbolizes a new era in human spaceflight for the participating nations.
Largest Science Mission Yet for Axiom
The Ax-4 crew will conduct approximately 60 scientific studies and activities representing 31 countries, including the U.S., India, Hungary, Poland, Brazil, Saudi Arabia, Nigeria, the UAE, and others across Europe and Asia. These studies span human health, Earth observation, biological and material sciences, and aim to significantly enhance international collaboration in microgravity research.
Axiom Space said this would be their most science-intensive mission to date, highlighting a broad participation from global stakeholders and showcasing the growing importance of low-Earth orbit (LEO) research.
A Personal Note from India’s Gaganyatri
Speaking about his journey and fellow crewmembers, Group Captain Shukla shared a heartfelt message:
“The team that I’m flying with is fantastic. I do feel I have exceptional crewmates. These are moments that tell you you’re part of something much larger than yourself. I feel extremely fortunate and hope to use this mission to inspire an entire generation back home. If my story can change even one life, that will be a huge success for me.”
As repairs are underway and a new launch date is anticipated, global anticipation remains high for what promises to be a landmark mission in international spaceflight and scientific research. (ANI)
