Axiom-4 launch mission with Indian astronauts repeatedly delayed to June 19 – Passionategeekz –

[CNMO Technology News]The Axiom-4 manned space mission, originally scheduled to be launched on May 29, has experienced many technical problems and delays since its announcement. The mission carried four international astronauts, including Indian astronaut Shubhanshu Shukla, to the International Space Station (ISS), marking an important step for India in the field of international commercial manned space. However, due to a series of technical and safety issues, the launch time has been repeatedly delayed.

According to the latest announcement by the Indian Space Research Organization (ISRO) and the Minister of Earth Sciences Dr Jitendra Singh on June 11, the launch date of the Axiom-4 mission has now been rescheduled on June 19, 2025.

The mission was originally scheduled to be carried out on May 29, but the cable system of the Dragon spacecraft module was abnormal and was postponed to June 8 for the first time. Subsequently, the launch was postponed to June 9 as the Falcon 9 rocket was not completed. The harsh meteorological conditions led to the postponement of the launch until June 10.

What is even more worrying is that during the preparation of the Heat Test on June 8, engineers discovered liquid oxygen leakage in the engine compartment and found that there was an abnormality in an engine actuator. The relevant components have been replaced and the controller has been upgraded. After the liquid oxygen problem is expected to be resolved quickly, the launch time was once adjusted to June 11.

On June 10, Axiom Space and SpaceX reported to the ISRO delegation on the current technical status. ISRO recommends on-site repair or replacement of key parts and conduct low-temperature sealing tests to verify system performance and reliability.

However, on June 11, NASA also reported that it is jointly assessing new signs of pressure abnormality in the tail section of the Zvezda service module of the International Space Station with the Russian State Space Corporation. This section has been repaired before, but there is still suspected leakage problem and further investigation is needed. Affected by this, the Axiom-4 mission was delayed again.

At the latest coordination meeting, ISRO, Axiom Space and SpaceX confirmed that the Falcon 9 liquid oxygen leakage problem had been successfully resolved. At the same time, Axiom is working closely with NASA to continue to evaluate the pressure abnormalities in the ISS service compartment.

As technical problems are gradually cleared, the Axiom-4 mission is now scheduled to be launched on June 19, when Indian astronaut Shukla will enter the International Space Station for the first time, opening a new chapter in India’s international manned commercial space.
