ISRO Complete 7,700 Ground Tests for Gaganyaan Human Spaceflight Program
New Delhi, India : The Indian Space Research Organisation (ISRO) has successfully completed 7,700 ground tests for its ambitious Gaganyaan human spaceflight program, with an additional 2,300 tests scheduled before the first crewed mission. This extensive testing phase is critical to ensuring the safety and reliability of the mission, which aims to send Indian astronauts into space for the first time.
The Gaganyaan mission is a significant step in India's space exploration efforts. It is planned to demonstrate human spaceflight capability by launching a crew of three members into a 400 km orbit for a three-day mission and returning them safely to Earth. The mission is expected to take place in early 2027, following a series of uncrewed test flights.
A key component of the mission's safety protocols is the parachute recovery system. In August 2025, ISRO successfully conducted the first Integrated Air-Drop Test (IADT-01) for the Gaganyaan mission at the Satish Dhawan Space Centre. This test involved dropping a 5-ton dummy crew capsule from a Chinook helicopter, with parachutes deploying in sequence to ensure a controlled splashdown in the Bay of Bengal. The recovery parachute system, developed by Agra-based ADRDE, a DRDO lab, includes four types of parachutes—Apex Cover Separation, Drogue, Pilot, and Main—that work together to reduce the capsule's velocity during descent.
Looking ahead, ISRO plans to conduct three uncrewed missions as part of the Gaganyaan program. The first uncrewed flight is scheduled for December 2025 and will carry Vyommitra, a humanoid robot designed to simulate human functions in space. This will be followed by two more unmanned missions in 2026, which will further test the spacecraft's systems and recovery procedures.
The Gaganyaan mission is a testament to India's growing capabilities in space technology and its commitment to advancing human space exploration. With meticulous planning and rigorous testing, ISRO is paving the way for a successful and historic crewed mission in 2027.
