ISRO also pointed out that the launch was first scheduled for May 29, 2025. But then it was postponed to June 8, 2025, because of the concerns in the electrical harness in the Crew Dragon Module, which was important for the transport of the crew. The mission was then again postponed to June 9, 2025, because of the delay in the preparedness of the Falcon-9 vehicle.“Another reason for the delay was the anomaly in one of the engine actuator which was replaced along with the controller. ISRO has recommended carrying out in-situ repairs or replacement and conduct a low-temperature leak test to validate system performance and integrity, before proceeding with launch clearance,” ISRO team said.Experts in ISRO said they have also recommended to NASA, Axiom Space and Roscosmos to evaluate the new pressure points that have indicated the air leak in the aft most segment of the ISS Zvezda Russian service module, after the recent repair attempt. Until test reports around are found to be satisfactory, the Ax-4 mission will stand postponed, ISRO experts said.
