**Summary:**

The Axiom-4 mission to the International Space Station (ISS), which included Indian astronaut-designate Shubhanshu Shukla, has been indefinitely postponed due to a liquid oxygen (LOX) leak detected in SpaceX’s Falcon 9 rocket. This mission is significant as it would mark the return of an Indian to space after 40 years and the first Indian to the ISS. The mission is a commercial venture facilitated by NASA contracting Axiom Space, who in turn contracted SpaceX. ISRO has invested significantly in the mission. The leak detection is a complex and time-consuming process involving various methods to identify the source. While launch windows for the ISS are relatively frequent, the delay’s duration remains uncertain due to the need for thorough inspection and repairs, as well as the coordination of docking schedules at the ISS.

**Axiom-4 Launch Delay Dashes Hopes for Indian Astronaut’s Historic ISS Visit**

**Bengaluru, June 12, 2025** – The planned launch of the Axiom-4 mission to the International Space Station (ISS), carrying Indian astronaut-designate Shubhanshu Shukla, has been indefinitely postponed due to a critical liquid oxygen (LOX) leak detected in the SpaceX Falcon 9 rocket. The announcement, made by Axiom Space on June 10th, has put a hold on what would have been a historic moment for India, marking its return to space after four decades and the first Indian presence on the ISS.

The Axiom-4 mission is a commercial undertaking, with NASA contracting Axiom Space, who in turn has contracted SpaceX. The four-member crew, composed of Peggy Whitson, Shubhanshu Shukla, Sławosz Uznański-Wiśniewski, and Tobir Kapu, were set to embark on a mission carrying crucial cargo to the ISS. The Indian Space Research Organisation (ISRO) invested over Rs 500 crore in Shukla’s flight following a collaborative effort to strengthen India-US ties.

The setback arose during routine pre-flight testing when a LOX leak was identified in one of the Falcon 9’s engines. LOX, a cryogenic fuel vital for generating thrust, is volatile and requires meticulous handling, making the leak a significant concern.

SpaceX engineers are now engaged in a thorough investigation to pinpoint the source of the leak, a process complicated by the cryogenic nature of LOX and the insulated or inaccessible locations of many joints and components. Experts will utilize various leak-detection techniques, including visual inspection, bubble tests, and thermal imaging.

While the delay is a disappointment, NASA has indicated that launch windows to the ISS occur with relative frequency, providing opportunities later in June and July. However, the mission’s rescheduling is contingent on resolving the LOX leak, securing an available docking port at the ISS, and favorable weather conditions.

The delay leaves Shukla and the Axiom-4 crew in a holding pattern, awaiting the green light for their mission to the ISS.
