ISRO Sends Crew Module on Gaganyaan’s First Uncrewed Mission

A significant milestone in India’s human space exploration adventure was reached when the Crew Module for the first uncrewed mission under the Gaganyaan project was sent out. The Satish Dhawan Space Centre in Sriharikota has received the module, which was connected with a liquid propulsion system at the Liquid Propulsion Systems Centre (LPSC) in Bengaluru. A component of India’s endeavors to obtain human spaceflight capability, this development was accomplished on January 21, 2025.
India’s ambitious human spaceflight program, Gaganyaan, intends to show that it can send astronauts into space. ISRO will carry out uncrewed test flights prior to the crewed mission in order to guarantee the mission’s dependability and safety.
Pitch, Yaw, and Roll are precisely controlled by the bi-propellant-based Reaction Control System (RCS) of the Crew Module Propulsion System (CMPS), which is integrated at LPSC, during the module’s descent and re-entry phases. The crew module is guided by the mechanism until parachutes are released for deceleration after the service module separates. In addition to a pressurization system, high-pressure gas bottles, and fluid control parts, it has 12 rocket motors, also referred to as 100 N thrusters.
The module also included the Crew Module Uprighting System (CMUS), which was created by the Vikram Sarabhai Space Centre (VSSC). During the crew module’s descent, this system makes sure it is oriented correctly.
Additional integration procedures for the Crew Module will shortly be carried out at VSSC, such as electrical harnessing, avionics package assembly, and system inspections. After that, it will be shipped to Bengaluru’s U R Rao Satellite Centre for the last stage of Orbital Module integration.
This is a significant step toward India’s first human spaceflight, demonstrating the country’s progress in space research and technology.
