Timeline
The Gaganyaan Mission has undergone meticulous planning and development phases. ISRO has been working diligently to meet the ambitious timelines set for this mission. While the exact launch date has evolved over time, ISRO remains committed to launching the mission within the stipulated timeframe. Several precursor missions are planned to demonstrate the Technology Preparedness Levels before the real Human Space Flight mission. These demonstration missions include the Integrated AirDrop Test (IADT), Pad Abort Test (PAT), and Test Vehicle (TV) flights. The safety and dependability of all systems will be shown in unmanned missions before manned operations.
Components of the Gaganyaan Mission
The Mission comprises several key components, including the crew module, launch vehicle, and ground facilities. The crew module is designed to ensure the safety and comfort of the astronauts during their journey into space. ISRO has developed a reliable launch vehicle capable of carrying the crew module into orbit.
1. Crew Module
The Gaganyaan crew module is a completely autonomous 5.3 t (12,000 lb) spaceship designed to transport a three-person crew to orbit and safely return to Earth after up to seven days. The crew module is outfitted with two parachutes for redundancy, with one sufficient for a safe splashdown. The parachutes would lower the crew module's speed from over 216 m/s (480 mph) to less than 11 m/s (25 mph) upon splashdown. The space capsule will have life support and environmental control systems. It will include emergency mission abort capabilities and a Crew Escape System (CES) that may be used during the first or second rocket stage burn.
2. Launch Vehicle
Human rated LVM3 - HLVM3
The launch vehicle for the mission has been designated as the ISRO LVM3 rocket, a well-proven and dependable heavy-lift launcher. It consists of three stages: solid, liquid, and cryogenic. All systems in the LVM3 launch vehicle have been re-configured to suit human rating criteria, and it is now known as the Human Rated LVM3. HLVM3 will be capable of launching the Orbital Module into a 400-kilometre low Earth orbit.
HLVM3 has a Crew Escape System (CES) driven by a series of rapid-acting, high-burn rate solid motors that guarantee the Crew Module and crew are transported to a safe distance in the event of an emergency on the launch pad or during ascent.
Orbital Module
The Orbital Module (OM) that will orbit Earth is made up of the Crew Module (CM) and the Service Module (SM). OM is outfitted with cutting-edge avionics technologies that have appropriate redundancy to ensure human safety.
CM is a livable habitat in space that provides the crew with an Earth-like environment. It is double-walled, with a pressurized metallic inner structure and an unpressurized external structure equipped with a Thermal Protection System (TPS). It contains crew interfaces, human-centred products, life support systems, avionics, and deceleration systems. It is also built for re-entry to safeguard the crew's safety during descent and landing.
SM will be utilized to provide critical assistance to CM while in orbit. It is an unpressurized framework that contains thermal, propulsion, electrical, and avionics systems, as well as deployment mechanisms.
Milestones and Progress
Since its inception, The Gaganyaan Mission has witnessed significant developments:1. Crew Selection
The Indian Prime Minister Narendra Modi unveiled the identity of the first four Indian astronauts who may go in the human space flight: Gp Capt Prashanth Balakrishnan Nair, Gp Capt Ajit Krishnan, Gp Capt Angad Prathap, and Wg Cdr Shubanshu Shukla on February 27, 2024. These individuals might be a part of India's forthcoming ISS expedition (likely Axiom expedition 4) and crewed space flight from India. They are all wing commanders or group captains in the Indian Air Force (IAF) and have extensive experience as test pilots.
