Gaganyaan is India’s first human spaceflight program, initiated by ISRO. It aims to send Indian astronauts (Gagannauts) into low Earth orbit (LEO) for 3–7 days.

Key Components:

• Orbital Module: Consists of the crew module and service module.

• Launch Vehicle: Modified GSLV Mk III, renamed as HLVM3 (Human-rated LVM3).

• Training: Indian Air Force pilots are being trained in Russia and India.

Objectives:

• Demonstrate crewed orbital flight capability.

• Ensure human safety with life-support systems, escape systems, and re-entry technologies.

• Lay the groundwork for future space stations or Moon missions.

Preparations:

• Conducted multiple crew escape system tests.

• Vyommitra, a female-looking humanoid robot, will be sent in an uncrewed mission to simulate human functions.

• First uncrewed mission (G1) is expected in 2025, followed by the crewed flight in 2026.

Significance:

• Positions India as the fourth country (after USA, Russia, and China) to send humans to space.

• Encourages development of indigenous technologies like astronaut suits, space food, and medical systems.

• Stimulates private sector participation in the Indian space ecosystem.

The Gaganyaan mission is a turning point in India’s space journey. It reflects ISRO’s ambitions beyond satellites and lunar probes, aiming for self-reliant human space exploration, and opens avenues for international collaborations in manned missions.
