ISRO Chairman V Narayanan has confirmed that Gaganyaan-G1, the first uncrewed test flight of India’s maiden human spaceflight mission, is scheduled for December 2026, marking a major milestone in the country’s effort to independently send astronauts into space.

The mission will be the first orbital flight under the Gaganyaan program and is intended to validate the critical systems required for future human spaceflight. It will be launched aboard the human-rated HLVM3 rocket from the Satish Dhawan Space Centre in Sriharikota.

According to Narayanan, the program has made substantial progress, with approximately 7,700 of the planned 10,000 tests completed, representing around 80 per cent of the overall test campaign. The remaining qualification activities are expected to continue through March 2027 as ISRO finalises the systems required for crewed operations.

G1 will be the first in a series of uncrewed missions designed to thoroughly assess the spacecraft, launch vehicle, safety mechanisms and recovery procedures before astronauts are sent into orbit. The phased approach reflects ISRO’s emphasis on mission assurance and human safety.

The flight is expected to carry Vyommitra, ISRO’s half-humanoid robotic astronaut, which has been developed to simulate human presence inside the spacecraft. The robot will help engineers evaluate cabin conditions, life-support performance and other critical systems that future crew members will rely upon during flight.

The mission will also test the performance of the Crew Module and Service Module in low-Earth orbit, validate re-entry technologies, and demonstrate recovery operations following splashdown. These capabilities are considered essential before India undertakes its first crewed space mission.

Over recent years, ISRO has conducted a series of major demonstrations, including crew escape system tests, parachute qualification exercises, air-drop trials and module separation tests. These activities form part of the broader effort to certify the Gaganyaan architecture for human spaceflight.

The HLVM3, developed specifically for carrying astronauts safely into space, incorporates several modifications and redundancies compared with standard launch vehicles. It will serve as the backbone of India's human spaceflight ambitions.

Gaganyaan represents India's most ambitious human space exploration initiative to date. The long-term objective is to demonstrate the capability to launch Indian astronauts into low-Earth orbit, keep them in space for several days, and return them safely to Earth.

With the first uncrewed flight now targeted for December 2026, the program is entering its most critical phase as ISRO works towards achieving India's historic human spaceflight goal.
