India’s journey toward human space exploration marked a critical step with the dispatch of the Crew Module for the first uncrewed mission under the Gaganyaan project. The module, integrated with a liquid propulsion system at the Liquid Propulsion Systems Centre (LPSC) in Bengaluru, has been sent to the Satish Dhawan Space Centre in Sriharikota. This development, achieved on 21 January 2025, is part of India’s efforts to attain human spaceflight capabilities. Liquid Propulsion System Details As reported by the Economic Times, according to ISRO, the Crew Module Propulsion System (CMPS) incorporates a bi-propellant Reaction Control System (RCS). This system is essential for precise three-axis control—pitch, yaw, and roll—during the descent and re-entry phases. Control operations will commence after the separation of the service module and continue until the parachute-based deceleration system is deployed. The propulsion system includes 12 thrusters, each delivering 100 Newtons of thrust, along with high-pressure gas bottles, a propellant feed mechanism, and associated fluid control components. Assembly and Integration The module’s development also involved the integration of the Crew Module Uprighting System …
