India’s First Human Space Mission: The Gaganyaan Programme Explained
Introduction to Gaganyaan – India’s First Crewed Space Mission
The Gaganyaan Mission is India’s first human spaceflight programme, developed by the Indian Space Research Organisation (ISRO). It is a landmark step in India’s space journey, aiming to send Indian astronauts, known as Vyomanauts, into space aboard an indigenously developed spacecraft.
With the launch of the Gaganyaan mission, India is poised to become the fourth nation in the world—after the USA, Russia, and China—to demonstrate human spaceflight capabilities independently.
What is the Gaganyaan Programme?
The Gaganyaan mission (Sanskrit for “Skycraft”) is a critical step in India’s ambition to develop independent human spaceflight capabilities. The programme is designed to send 2–3 astronauts into Low Earth Orbit (LEO) at an altitude of approximately 400 kilometers and safely return them to Earth.
Key Highlights:
Mission Name: Gaganyaan
Agency: ISRO (Indian Space Research Organisation)
Crew: 2–3 astronauts
Orbit: Approximately 400 kilometers above Earth (LEO)
Duration: Up to 7 days
Launch Vehicle: LVM-3 (formerly GSLV Mk III)
Launch Site: Satish Dhawan Space Centre, Sriharikota
Estimated Cost: ₹10,000 crore (approximately $1.25 billion)
Objectives of the Gaganyaan Mission
Demonstrate safe human spaceflight capability
Develop indigenous technologies such as life-support systems, crew modules, and escape systems
Strengthen national prestige in space exploration
Boost scientific research and innovation
Lay the groundwork for future crewed missions, such as lunar missions and space stations
Astronaut Selection and Training
Who are the Vyomanauts?
Four Indian Air Force (IAF) pilots have been shortlisted as potential crew members. Their training, facilitated by Roscosmos (Russia’s space agency), includes:
Zero-gravity simulation
Emergency and survival training
Space medicine
Life-support system operation
Simulator-based mission rehearsals
ISRO has also developed the Human Space Flight Centre (HSFC) in Bengaluru to oversee mission operations and astronaut training.
Technology Behind the Gaganyaan Mission
To ensure mission success, ISRO has developed and tested several critical spaceflight technologies:
Crew Module
A pressurized capsule that will carry astronauts. It includes life-support systems, thermal protection, and a communications system.
Service Module
This contains propulsion and support systems such as power supply and attitude control.
Crew Escape System
A system designed to evacuate astronauts quickly and safely in case of a launch emergency.
Launch Vehicle: LVM-3
A three-stage heavy-lift rocket capable of placing the Gaganyaan spacecraft into orbit.
