What is Gaganyaan Mission?

  • India's first human space mission.
  • Mission of - Indian Space Research Organisation (ISRO)
  • Objective- To send humans into space on a Low Earth Orbit of 400 km for 3 days and bring them safely back to the Earth
  • Timeline - By 2025
  • Components - Crew module (CM) and the service module (SM), which together will form the orbital module.
    • Crew Module- It is the habitable space with Earth like environment in space for the crew and is designed for re-entry to ensure safety of the crew during descent till touchdown.
    • Service Module- It is an unpressurized structure that will be used for providing necessary support to CM while in orbit.

gaganyaan

  • Launch Vehicle - Launch Vehicle Mark III (LVM3)
  • Other features - For Gaganyaan, ISRO signed an agreement with Russia's Glavkosmos to select and train Indian astronauts.
  • The US has also offered to provide advanced training to the astronauts selected for the Gaganyaan.
  • The second phase of this mission will involve the launch of Vyommitra, a female spacefaring half humanoid robot that will function as a prototype for the Gaganyaan missions.
  • Astronaut training facility is established in Bengaluru.

If it succeeds, India will become only the 4th country to send a human into space after the Soviet Union, the US, and China.

LVM3 & HLVM3

  • LVM3  - It is the heaviest rocket of ISRO.
  • It was earlier called Geosynchronous Launch Vehicle Mark III (GSLV Mk III).
  • It consists of 3 stages - solid, liquid and cryogenic stage.
  • HLVM3- All systems in LVM3 launch vehicle are re-configured to meet human rating requirements and christened Human Rated LVM3.
  • It consists of Crew escape system 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.

What tests were planned as a part of the mission?

gaganyaan

  • Integrated Air Drop Tests- It involve dropping a simulated crew module from an aircraft and deploying parachutes to slow down its descent and land safely in the sea.
  • The tests also verify the performance of the flotation system.
  • Test Vehicle Missions- It involve launching a single-stage liquid propulsion rocket, equipped with a crew module and a crew escape system.
    • Test Vehicle Abort Mission-1 (TV-D1) was successfully demonstrated by the ISRO recently.
  • Pad Abort Tests (PAT)-  It is a test of a launch escape system, which is designed to quickly get the crew and spacecraft away from the rocket in case of an emergency on the launch pad.
  • Uncrewed mission- Its purpose is technology demonstration, safety and reliability verification and studying the performance of systems before crewed flight.
  • Manned flight mission- It carries human crew members who operates its control and performs various tasks.

Test Vehicle Abort Mission-1 (TV-D1)

  • It is an in-flight abort demonstration of Crew Escape System (CES) at Mach number 1.2 followed by Crew Module separation and safe recovery.
  • TV- D1 features a single-stage rocket powered by liquid propellants for this mission.
  • It carries payloads including the
    • Crew Module (CM)- It will take the crew to the space which is under development and is being tested.
    • Crew Escape System (CES)- In case of any damage to the rocket, the crew will have to be taken away from the rocket and saved.

What are the benefits of undertaking Gaganyaan mission?

  • Future explorations- It will make a progress towards a sustained and affordable human and robotic programme to explore the solar system and beyond.
  • Technology- Advanced technology capability for undertaking human space exploration, sample return missions and scientific exploration.
  • Future capability- To actively collaborate in global space station development & to carry out scientific experiments of interest to the nation.
  • Partnership- Create a broad frame work for wider Academia – Industry partnership in taking up development activities for national development.
  • Job creation- It provides for an ample scope for employment generation and human resource development in advanced science and R&D activities.
  • Foster scientific temper- It will provide unique opportunity to inspire and excite Indian youth and steer many students towards career in science and technology.
  • Global leader -The programme will strengthen international partnerships and global security through the sharing of challenging and peaceful goals.
  • Having a vibrant human spaceflight programme can be leveraged as a potent foreign policy.
