GN Bureau | December 21, 2022
India’s maiden human space flight ‘H1’ mission is targeted to be launched in the fourth quarter of 2024, according to union minister of state for atomic energy and space Dr Jitendra Singh.
In a written reply to a question in the Lok Sabha on Wednesday, Dr Singh said, in view of the paramount importance of crew safety, two Test Vehicle missions are planned before the ‘G1’ mission to demonstrate the performance of crew escape system and parachute-based deceleration system for different flight conditions.
Dr Singh said the uncrewed ‘G1’ mission is targeted to be launched in the last quarter of 2023 followed by the second uncrewed ‘G2’ mission in the second quarter of 2024, before the final human space flight ‘H1’ mission in the fourth quarter of 2024.
He said the first uncrewed flight of Gaganyaan programme, i.e., ‘G1’ mission is aimed at validating the performance of Human rated launch vehicle, Orbital module propulsion system, mission management, communication system and recovery operations. The mission will carry a humanoid as payload.
The minister said, the astronaut designates for human space flight mission are identified and are currently undergoing their mission specific training in Bengaluru. The first semester of astronaut training has been completed wherein they have undergone course modules on theoretical basics, space medicine, launch vehicles, spacecraft system and ground support infrastructure. Regular physical fitness sessions, aeromedical training and flying practice are also part of crew training. Corresponding evaluation and assessment activities have also been completed. The second semester of crew training is currently in progress.
The Gaganyaan project envisages demonstration of human spaceflight capability by launching crew of three members to an orbit of 400 km for a three-day mission and bring them back safely to earth, by landing in Indian sea waters.
The project is accomplished through an optimal strategy by considering in-house expertise, experience of Indian industry, intellectual capabilities of Indian academia & research institutions along with cutting edge technologies available with international agencies. The pre-requisites for Gaganyaan mission include development of many critical technologies including human rated launch vehicle for carrying crew safely to space, life support system to provide an earth like environment to crew in space, crew emergency escape provision and evolving crew management aspects for training, recovery and rehabilitation of the crew.
Various precursor missions are planned for demonstrating the Technology Preparedness Levels before carrying out the actual Human Space Flight mission. These demonstrator missions include Integrated Air Drop Test (IADT), Pad Abort Test (PAT) and Test Vehicle (TV) flights. Safety and reliability of all systems will be proven in unmanned missions preceding manned mission.
Human rated LVM3 - HLVM3
LVM3 rocket - The well proven and reliable heavy lift launcher of ISRO, is identified as the launch vehicle for Gaganyaan mission. It consists of solid stage, liquid stage and cryogenic stage. All systems in LVM3 launch vehicle are re-configured to meet human rating requirements and christened Human Rated LVM3. HLVM3 will be capable of launching the Orbital Module to an intended Low Earth Orbit of 400 km.
HLVM3 consists of Crew Escape System (CES) powered by a set of quick acting, high burn rate solid motors which ensures that Crew Module along with crew is taken to a safe distance in case of any emergency either at launch pad or during ascent phase.
