Indian Astronaut Shubhanshu Shukla’s Axiom-4 Mission to ISS Postponed Again | NASA Cites Safety Review

Indian astronaut Shubhanshu Shukla’s Axiom-4 mission to the ISS has been postponed due to ongoing NASA evaluations after repairs in the Zvezda module.

Washington, D.C. / Bengaluru – The Axiom-4 mission to the International Space Station (ISS), featuring Indian astronaut Shubhanshu Shukla, has been postponed once again, according to a statement from NASA.

The U.S. space agency confirmed that additional time is needed to assess the ISS's operational readiness, especially following recent repair work in the Zvezda service module, located in the aft-most segment of the orbital laboratory.

This marks the second delay for the high-profile #Axiom4 mission, which includes India’s Shukla among the international crew selected by Axiom Space, the private spaceflight company working in partnership with NASA and SpaceX.

“NASA continues to evaluate systems aboard the ISS after maintenance activities in the Zvezda module. We are prioritizing safety and mission integrity,” the agency stated.

Shubhanshu Shukla: India’s Next Man in Space

Shubhanshu Shukla, a former Indian Air Force pilot and test astronaut, is set to become India’s second person in space after Rakesh Sharma, and the first Indian astronaut to fly on a commercial space mission. His participation in the mission marks a historic collaboration between ISRO, NASA, and Axiom Space, symbolizing India’s growing role in global human spaceflight programs.

Mission Objectives and Future Outlook

The Axiom-4 mission aims to conduct a range of scientific experiments, Earth observation tasks, and technology demonstrations aboard the ISS. Shukla was also scheduled to carry experiments designed by Indian universities and startups, focusing on microgravity research and space health.

A new launch date has not yet been announced, but officials say updates will follow after further technical assessments are complete.

Growing Global Interest in India’s Space Journey

The delay has not dampened public interest in the mission, especially in India, where Shukla's journey is being closely followed. Social media has seen a surge in support, with hashtags like #ShubhanshuShukla and #Axiom4 trending following the news.

Industry analysts believe that this mission will pave the way for future Indian participation in commercial spaceflight and build momentum for India’s own Gaganyaan human spaceflight program, scheduled for late 2025 or 2026.
