A key highlight of this mission is the participation of Group Captain Shubhanshu Shukla from India, a serving Indian Air Force pilot and ISRO’s latest astronaut. He is set to become one of the few Indians to ever reach the ISS. The crew also includes mission commander and veteran astronaut Peggy Whitson, Hungary’s Tibor Kapu, and Poland’s Slawosz Uznanski-Wisniewski, both serving as mission specialists.

According to a joint statement from NASA, Axiom Space, and SpaceX, the delay is to allow further assessments following recent repair work on the Zvezda service module, one of the older Russian segments of the ISS. The decision prioritizes safety and mission readiness. Earlier, engineers had also identified a liquid oxygen leak in the Falcon 9 rocket’s boosters, prompting the first round of delays.
The mission will lift off from NASA’s Kennedy Space Center in Florida aboard a SpaceX Falcon 9 rocket. Shukla is expected to carry out seven Indian-developed experiments, along with collaborative research projects involving NASA.
