Introduction
In a significant leap for India’s space program, the Gaganyaan mission is poised to mark a historic moment. For the first time, Indian astronauts — called Vyomnauts — will be launched into space aboard an Indian spacecraft. The mission demonstrates India’s technological strength and aspirations to become a key player in human space exploration.
Led by ISRO (Indian Space Research Organisation), Gaganyaan is not just a space mission; it’s a statement of India's capabilities, resilience, and readiness to explore new frontiers.
What is Gaganyaan?
“Gaganyaan” literally means “Sky Craft” in Sanskrit. It is India's first crewed orbital mission, designed to send 3 astronauts into low-Earth orbit (~400 km altitude) for up to 3 days, and safely return them to Earth.
Gaganyaan aims to demonstrate:
-
Human spaceflight capabilities
-
Advanced life support systems
-
Re-entry technology
-
Space medicine and astronaut training
Timeline & Key Milestones
| Milestone | Status |
|---|---|
| Gaganyaan Project Approved | 2018 |
| First Uncrewed Test Flight (G1) | Scheduled in 2025 |
| Second Uncrewed Flight with Robot ‘Vyommitra’ | Mid-2025 |
| Crewed Flight with 3 Astronauts | End of 2025 or early 2026 |
Budget Allocated: ₹10,000+ crore (approx. $1.3 billion)
Key Components of the Mission
🚀 Human-Rated Launch Vehicle (HLVM3)
-
Modified version of the GSLV Mk III, certified for human safety
-
Capable of carrying a 3-member crew and all onboard systems
🛰️ Orbital Module
-
Crew Module: Where astronauts will live and operate
-
Service Module: Houses propulsion and power systems
🔄 Crew Escape System (CES)
-
A life-saving system that can jettison the crew to safety during any failure in launch phase
👨🚀 Vyomnauts
-
4 Indian Air Force pilots have been selected and trained in Russia and India
-
Undergoing intense training in microgravity, life support, space medicine, and simulators
International Collaboration
-
Russia’s Roscosmos trained Indian astronauts
-
France’s CNES helped with space medicine and health systems
-
Collaboration with NASA and ESA for backup tech and best practices
-
Indian firms like HAL, L&T, BEL contributed to spacecraft components
Technology Demonstrations
India has already successfully tested:
-
Pad Abort Test (2018): Validated crew escape system
-
Test Vehicle TV-D1 (2023): Simulated abort and recovery
-
Heat shield and re-entry system: Crucial for crew module safety
Upcoming Test Flight G1 in 2025 will be uncrewed but will simulate full orbital mission.
