Why in the News?
Test flight success of Abort Mission-1 (TV-D1) this morning heralds successive sequential trial flights before the final Gaganyaan launch.
News in Brief
- Single engine rocket carrying an early depressurised version of Gaganyaan Crew Module (CM) to an altitude of around 17 Kilometre followed by final descent using a parachute for its splashdown.
- A critical step in the ISRO journey to launch a crewed human spacecraft through the Gaganyaan mission.
- Way for a series of tests of systems and procedures with the aim of ultimately launching an Indian astronaut into Space, possibly around the year 2025.
About Test Mission
- It tested the safety mechanism that will allow the crew of the Gaganyaan mission to escape the spacecraft in case the mission is aborted due to a malfunction.
- Objective of Mission
- Test vehicle subsystems are evaluated and demonstrated in flight.
- Evaluation and flight demonstration of the CES, encompassing several separation mechanisms.
- Features of the crew module include demonstrating the higher-altitude deceleration mechanisms and their recovery.
- The crew module successfully separated from the launch vehicle and the Indian Navy successfully recovered the module.
- With a rocket based upon the GSLV L40 stage, TV-D1 was to be launched up to 11 km above sea level, where an in-flight abort scenario would be initiated.
- The capsule was expected to then continue another 4–5 km.
- The mission aimed to test the CES’s separation from the rocket, ability to maintain a trajectory leading to a safe distance, and eventual parachute deployment.
About Gaganyaan Mission
- Gaganyaan project envisages a demonstration of human spaceflight capability by launching a crew of 3 members.
- Demonstration to an orbit of 400 km for a 3-day mission and bringing 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 cutting-edge technologies available with international agencies.
- The pre-requisites for the Gaganyaan mission include the development of many critical technologies including a human-rated launch vehicle for carrying the crew safely to space, a 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 crew.
- Various precursor missions are planned to demonstrate the Technology Preparedness Levels before carrying out the actual Human Space Flight mission.
- These demonstrator missions include the Integrated AirDrop Test (IADT), Pad Abort Test (PAT) and Test Vehicle (TV) flights.
- The safety and reliability of all systems will be proven in unmanned missions preceding manned missions.
- LVM3 rocket – The well-proven and reliable heavy lift launcher of ISRO, is identified as the launch vehicle for the Gaganyaan mission.
- The orbital Module (OM) that will be Orbiting Earth comprises of Crew Module (CM) and a Service Module (SM).
