India’s Indian Space Research Organisation (ISRO) has transformed the Chandrayaan-3 propulsion module into a valuable scientific asset, achieving unplanned deep-space flybys after its primary mission concluded. Following a successful soft landing on the Moon, ISRO executed a novel TransEarth Injection maneuver, allowing the module to enter an elongated orbit influenced by both Earth and the Moon. This innovative approach has provided essential data on gravitational interactions and disturbance torques, setting a precedent for future lunar and interplanetary missions. The successful utilization of existing assets showcases India’s technical capabilities and strategic foresight in space exploration, reinforcing its position as a key player in the evolving landscape of deep-space science and technology.
