ISRO to Conduct First Gaganyaan Uncrewed Test Flight in December 2025.

Science and Technology | Dated: 23 Aug 2025

On August 21, 2025, the Indian Space Research Organisation (ISRO) Chairman, V. Narayanan, officially confirmed that the first uncrewed Gaganyaan mission—carrying a humanoid space robot—will launch in December 2025, marking a pivotal milestone in India’s human spaceflight aspirations.

🎯 Key Highlights:

  • - ISRO’s upcoming Gaganyaan-1 (G1) mission will be the programme’s maiden uncrewed orbital flight. It will carry Vyommitra, a half-humanoid robotic astronaut, to simulate human functions and monitor critical spacecraft systems such as environmental controls, avionics, and life support.
  • - The mission is scheduled for December 2025, with launch operations to be conducted from the Satish Dhawan Space Centre (SDSC–SHAR). The spacecraft will conduct a low Earth orbit mission—including system validation through orbital maneuvers and recovery—before safely reentering.

💡 Other Important Facts:

  • (i) ISRO has declared 2025 as ‘Gaganyaan Year’ under Chairman V. Narayanan’s guidance. Over 7,200 system tests have been completed while approximately 3,000 more are pending. Preparations continue 24/7 to ensure all systems are flight-ready.
  • (ii) G1’s core objective is to achieve a three-day orbital stay, during which Vyommitra and other onboard instruments will assess life-support systems, navigation, re-entry dynamics, and spacecraft resilience under microgravity, radiation, and thermal stress. This will validate critical parameters ahead of crewed missions.
  • (iii) The successful launch of G1 is the first in a series of at least three uncrewed test flights, paving the way for India’s inaugural crewed Gaganyaan flight, targeting early 2027. This mission will carry one to three astronauts in a short orbital test, placing India among global leaders in human spaceflight.
