ISRO Chief Reveals Big Test In Space Quietly Accomplished During The LMV3 Launch On Nov 2

Indian Space Research Organisation (ISRO) quietly conducted a significant test during Sunday's CMS-03 satellite launch from the Satish Dhawan Space Centre at Sriharikota on November 2. In an exclusive conversation with India Today TV’s Pramod Raghavan, ISRO chief Dr V Narayanan highlighted a major milestone – the successful in-orbit test of the indigenously developed C25 cryogenic stage. This breakthrough shows ISRO’s advancing technological prowess, particularly in enhancing space mission precision and efficiency. The C25 cryogenic stage, which will serve as the upper stage in the LVM-3 launch vehicle, was successfully ignited in orbit during the CMS-03 mission. This crucial milestone involved firing the thrust chamber of the C25 engine while in space, a first for ISRO, providing invaluable data on engine performance, stability, and control in microgravity conditions.
