NEW DELHI: (Jun 20) NASA has put off Sunday’s launch of the Axiom-4 mission carrying Indian astronaut Shubhanshu Shukla and three others to the International Space Station, saying it required additional time to evaluate operations on the orbital lab after the recent repairs in its Russian section.

The Axiom-4 mission was targeting a June 22 launch after being put off multiple times due to a leak in the boosters of SpaceX’s Falcon-9 rocket, inclement weather in the ascent trajectory and leaks in the aft-most section of Zvezda service module.

The space agency needs additional time to continue evaluating the International Space Station operations after recent repair work in the aft (back) most segment of the orbital laboratory’s Zvezda service module, it said.
