What is the Gaganyaan Mission?

About the Mission

The Gaganyaan mission stands as a testament to ISRO’s prowess in human spaceflight. This mission aims to showcase India’s capability to conduct space travel with a human crew, sending them to an orbit 400 km above Earth and ensuring their safe return.

Gaganyaan Mission Cost

In terms of financial investment, the Gaganyaan Programme comes with an estimated cost of around Rs 9023 crore. This funding is allocated to various aspects of the mission, covering the intricate details and technologies required to achieve the successful execution of this significant space endeavor.

Gaganyaan Mission launch vehicle

For the Gaganyaan mission, the launch vehicle selected is the GSLV Mk III, alternatively known as LVM-3.

To ensure compliance with human safety standards, the GSLV Mk III has undergone reconfiguration and is now officially named Human-Rated LVM-3.

This modification highlights the detailed preparations and adaptations made to the launch vehicle to meet the specific requirements and safety considerations for carrying human crew members into space.

Gaganyaan Mission Astronauts Traning

The selected astronauts for the Gaganyaan mission will undergo their training in Russia. As part of this comprehensive training program, they will be acquainted with the experience of flying in weightless conditions.

This training is essential to prepare the astronauts for the unique challenges and conditions they will encounter during their space mission, ensuring their readiness and adaptability to the demands of space travel.

This synergy of expertise and resources from diverse sectors underscores the holistic approach taken to ensure the success of the Gaganyaan Mission, reflecting the collaborative spirit driving India’s advancements in space exploration.

Aims & Objectives of Gaganyaan Mission:

Human Space Capability

The primary objective of the Gaganyaan mission is to showcase India’s prowess in launching human beings into low Earth orbit and ensuring their safe return to Earth.

This ambitious undertaking is geared towards demonstrating and establishing India’s capability in the field of human space travel.

Scientific Career

Beyond its technological milestones, the Gaganyaan mission aspires to catalyze inspiring individuals to pursue careers in Science and Technology within the country. By achieving this feat, the mission aims to encourage and ignite the passion for scientific exploration, fostering a new generation of talent in India’s scientific community.

Integral Components of the Gaganyaan Spacecraft

Orbital Module

At the heart of the Gaganyaan Mission lies the Orbital Module (OM), serving as the central hub that will gracefully orbit the Earth. Comprising both the Crew Module (CM) and Service Module (SM), the OM will boast advanced avionics systems, ensuring its efficiency and functionality.

Service Module

The Service Module is a critical component encompassing the propulsion system, thermal system, power systems, avionics systems, and deployment mechanisms. This comprehensive set of elements is designed to offer essential support to the Crew Module during its orbital journey.

Crew Module

Crafted to provide an Earth-like environment in the vastness of space, the Crew Module is tailored for the comfort and safety of the crew. It features crew interfaces, human-centric products, life support systems, avionics, and deceleration systems, collectively creating a conducive space for the astronauts during their mission.

Stages and Key Achievements of the Gaganyaan Mission

Integrated AirDrop Test (IADT)

As a crucial segment of the Integrated Main Parachute Airdrop Test (IMAT) for the Parachute Deceleration System (PDS), a 5-ton dummy mass equivalent to the actual crew module was released from an altitude of 2.5 km by the Indian Air Force.

Pad Abort Test (PAT)

The Pad Abort Test serves as a critical trial to assess the spacecraft’s launch abort system. This system is designed to swiftly move the crew and spacecraft away from the rocket in the event of a potential failure.

Crew Abort Test Mission

In this mission, an unpressurized version of the crew module will be employed, incorporating systems for deceleration and recovery, including parachutes. Launched on a single-stage liquid rocket, the objective is to simulate an abort condition during the ascent trajectory corresponding to a Mach number of 1.2 in the Gaganyaan mission.

During the abort mission, the crew escape system and crew module will separate from the test vehicle at an altitude of approximately 17 km. Subsequently, the abort sequence will autonomously execute, leading to the deployment of a series of parachutes and ultimately ensuring the safe touchdown of the crew module in the Bay of Bengal.

Vyomitra

Anticipated to be part of the second uncrewed Gaganyaan mission, Vyomitra, a humanoid robot, is set to perform microgravity experiments and monitor module parameters. Simulating functions like a human from the waist up, Vyomitra can detect and issue warnings in the event of environmental changes within the cabin, ensuring the astronauts’ comfort.
