India’s hopes of sending Group Captain Shubhanshu Shukla to the International Space Station (ISS) hit another snag as the Axiom-4 (Ax-4) mission launch, scheduled for June 11, 2025, was postponed, marking the fifth delay. SpaceX announced the setback on June 10, 2025, citing a liquid oxygen (LOx) leak detected during post-static fire booster inspections of the Falcon 9 rocket. This historic mission, a collaboration between ISRO, NASA, Axiom Space, and SpaceX, aims to make Shukla the first Indian to visit the ISS. Here’s the latest on the delay, the mission’s significance, and what lies ahead
- Key Points:
- Launch delayed due to LOx leak in Falcon 9’s propulsion bay.
- Fifth postponement after weather-related delays since May 2025.
- New launch date pending repairs and range availability.
Why the Delay? Unpacking the Technical Snag
The Axiom-4 mission was set to lift off from NASA’s Kennedy Space Center in Florida at 5:30 PM IST on June 11, 2025. However, a seven-second hot test of the Falcon 9’s booster stage revealed a liquid oxygen leak, prompting SpaceX to halt the launch. ISRO Chairman Dr. V. Narayanan confirmed that repairs and validation tests are underway, with a new date to be announced soon. This follows earlier delays due to unfavorable weather, including high winds and a 45% chance of rain, pushing the launch from May 29 to June 11.
- Key Points:
- LOx leak detected during routine booster performance test.
- Previous delays caused by high winds and rain risks.
- SpaceX prioritizes safety with rigorous pre-launch checks.
Meet Shubhanshu Shukla: India’s Space Trailblazer
Group Captain Shubhanshu Shukla, a 39-year-old Indian Air Force pilot, is set to make history as the first Indian to visit the ISS and the second Indian in space, following Rakesh Sharma’s 1984 mission. As the pilot of Ax-4, Shukla will oversee autonomous launch and docking operations of the SpaceX Dragon spacecraft. With over 2,000 hours of flight experience and training in Russia, India, and the US, Shukla’s peers call him “wicked smart” and “focused.” He carries the dreams of 1.7 billion Indians, aiming to inspire the next generation.
- Key Points:
- Shukla to be first Indian on ISS, 41 years after Sharma’s flight.
- Trained for 8–12 months with NASA, SpaceX, and ISRO.
- Will conduct 7 India-centric experiments in microgravity.
The Axiom-4 Mission: A Global Endeavor
The Axiom-4 mission, costing India $70 million (Rs. 538 crore), is a landmark for private spaceflight. Led by Commander Peggy Whitson (former NASA astronaut), the crew includes Slawosz Uznanski-Wisniewski (Poland) and Tibor Kapu (Hungary), marking their nations’ first ISS missions in decades. The team will spend 14 days aboard the ISS, conducting 60 experiments in microgravity, including India’s food and nutrition studies like sprouting green gram. This mission, launching from Launch Complex 39A, is a step toward India’s Gaganyaan mission in 2027.
- Key Points:
- Crew to perform 60 experiments from 31 countries.
- India’s experiments focus on food, health, and microgravity.
- Mission cost: Rs. 413 crore already spent by ISRO.
The Road to Launch: A Series of Delays
The Axiom-4 mission has faced multiple hurdles:
- May 29, 2025: Delayed due to a minor technical issue.
- June 8, 2025: Postponed to June 10 for operational adjustments and quarantine protocols.
- June 10, 2025: Shifted to June 11 due to bad weather (45% rain chance, high winds).
- June 11, 2025: Delayed again for LOx leak repairs.
The crew, in pre-launch quarantine since May 25, follows strict health protocols to ensure mission safety.
- Key Points:
- Fifth delay reflects SpaceX’s commitment to safety.
- Crew in quarantine at Kennedy Space Center since May 25.
- Weather and technical issues caused prior postponements.
What’s Next for Axiom-4 and Shukla?
SpaceX is working to repair the LOx leak, with a new launch date to be confirmed once repairs are validated and the launch range is available. The Falcon 9 and Dragon spacecraft remain at Launch Complex 39A, ready for final checks. Once launched, the crew will dock with the ISS after a 28-hour flight, spending 14 days on experiments, outreach, and interactions with PM Narendra Modi and students. ISRO and Axiom Space remain confident in the mission’s success, a milestone for India’s space ambitions.
- Key Points:
- New launch date awaits repair completion and range clearance.
- Mission to dock with ISS for 14-day research stint.
- Boosts India’s prep for Gaganyaan 2027.
