Context:
- Gaganyaan Mission is India’s ambitious programme by ISRO (Indian Space Research Organisation) to send Indian astronauts (Vyomanauts) into space.
- It marks India’s entry into the elite group of nations capable of human spaceflight (USA, Russia, China).
Key Highlights:
Mission Objectives
- To demonstrate India’s capability to:
- Launch humans into Low Earth Orbit (LEO) (~400 km).
- Ensure safe return and recovery in Indian waters.
- Enhance India’s technological self-reliance in space.
Mission Components
Human-Rated Launch Vehicle (HLVM3 / LVM3)
- Modified version of GSLV Mk III.
- Equipped with enhanced safety and reliability systems.
Crew Module & Service Module
- Crew Module: Habitable space for astronauts with life support systems.
- Service Module: Provides propulsion, power, and thermal control.
Life Support System
- Maintains oxygen supply, temperature, pressure, and waste management.
Crew Escape System
- Emergency system to separate astronauts from rocket in case of failure.
Astronaut Training
- Conducted in collaboration with Russia (initial phase) and ISRO facilities.
- Focus on microgravity adaptation, survival training, and simulations.
Recent Developments
- Series of test missions (TV-D1, TV-D2) to validate escape systems.
- Uncrewed missions planned before final human flight.
- Selection of Indian Air Force test pilots as astronauts.
