BENGALURU: In an important milestone for India’s human spaceflight programme, the Liquid Propulsion Systems Centre (LPSC) of Isro has completed the integration of liquid propulsion systems on the Crew Module for Gaganyaan’s first uncrewed mission (G1).
“The Crew Module, dispatched on Jan 21, features a sophisticated bi-propellant based Reaction Control System (RCS) designed for precise three-axis control,” Isro said.
This system, known as the Crew Module Propulsion System (CMPS), will manage the spacecraft’s pitch, yaw, and roll during the critical descent and re-entry phase, operating from the moment of service module separation until the deployment of the parachute-based deceleration system.
The CMPS incorporates 12 thrusters, each capable of generating 100N of force, alongside a pressurisation system equipped with high-pressure gas bottles and a propellant feed system with associated fluid control components.
Additionally, the Crew Module Uprighting System (CMUS), developed by the Vikram Sarabhai Space Centre (VSSC), has been successfully integrated into the module at LPSC.
The next phase of development will see the Crew Module undergo further integration operations at VSSC, including avionics package assembly and electrical harnessing checks. Following these procedures, the module will be transported to the U R Rao Satellite Centre in Bengaluru for the final phase of Orbital Module integration.
