Indian Space Research Organisation (ISRO) engineers have potentially achieved a world-first by demonstrating a boot-strap mode start for the CE20 cryogenic engine. This breakthrough, tested for 10 seconds on November 7, 2025, allows the engine to restart in space without auxiliary systems, enhancing the LVM3 rocket's mission flexibility for multi-orbit deployments.

ISRO has successfully tested the critical parachute system for its Gaganyaan human spaceflight mission, validating the 10-parachute sequence under extreme conditions. A 2.5-tonne module was dropped from 2.5 km by an Indian Air Force IL-76, confirming the system can ensure astronaut safety during descent.
