Key Highlights
- ISRO has scheduled the crewed Gaganyaan flight for 2027 after a cascade of unmanned test missions.
- The initial uncrewed test, designated G1, will launch in March 2026 carrying the humanoid robot Vyommitra.
- Four astronaut candidates are undergoing intensive preparation while the LVM3 launch vehicle is being human‑rated.
- The mission will place a crew module in a 400 km low‑Earth orbit for roughly three days before a parachute‑aided splash‑down.
Detailed Insights
Gaganyaan represents India's flagship effort to achieve independent human spaceflight, putting the nation alongside the United States, Russia and China. The programme’s roadmap relies on three successive uncrewed flights that will interrogate every subsystem—structure, avionics, propulsion, software and life‑support—against a target safety score of 100 %. The first of these, G1, is about ninety percent complete, having already undergone more than 8,000 ground‑based and structural examinations.
Vyommitra, an advanced humanoid robot, will accompany the G1 launch to simulate crew presence. Its payload will test cabin environmental controls, re‑entry dynamics and recovery procedures, thereby furnishing data that human occupants will later rely upon.
Four selected Gaganyatris—Shubhanshu Shukla, Prasanth Balakrishnan Nair, Ajit Krishnan and Angad Pratap—are in the final stages of training. Parallel to their preparation, ISRO is validating the human‑rated LVM3 launch vehicle, the crew module’s thermal protection system, and an emergency escape tower. The complete mission profile envisions a three‑day orbital stint at an altitude of 400 km, followed by atmospheric re‑entry and a sea‑based recovery within Indian waters.
Key Concepts
- Human‑rated launch vehicle: A launch rocket modified and rigorously tested to meet safety criteria for crewed flight.
- Low‑Earth Orbit (LEO): An orbital band from roughly 160 km to 2 000 km above Earth’s surface, where the Gaganyaan crew will operate.
- Vyommitra: ISRO’s humanoid test‑bed robot designed to evaluate life‑support, environmental, and re‑entry systems in lieu of human subjects.
- Safety score of 100/100: ISRO’s internal benchmark requiring every subsystem to demonstrate flawless performance before authorizing crewed flight.
