ISRO completes key test on main parachutes for Gaganyaan Crew Module

The Indian Space Research Organisation (ISRO) recently conducted an important test on main parachutes for the Gaganyaan Crew Module.

The test was conducted at the Babina Field Firing Range (BFFR) in Uttar Pradesh's Jhansi on November 3, 2025 as part of the ongoing series of Integrated Main Parachute Airdrop Tests (IMAT) for the qualification of parachute system for Gaganyaan mission.

For the Gaganyaan Crew Module, the parachute system comprises a total of 10 parachutes of four types. The descent sequence begins with two apex cover separation parachutes that remove the protective cover of the parachute compartment, followed by two drogue parachutes that stabilise and decelerate the module.

“Upon release of the drogues, three pilot parachutes are deployed to extract three main parachutes, which further slow down the Crew Module to ensure a safe touchdown. The system is designed with redundancy — two of the three main parachutes are sufficient to achieve a safe landing,” the space agency said.

The main parachutes of the Gaganyaan mission deploy in a step-by-step process known as reefed inflation.

“In this process, the parachute first opens partially, which is called reefing, and then fully opens after a predetermined period of time, known as disreefing. This process is carried out using a pyro device,” it added.

In the recently concluded test, one of the possible extreme scenarios of delay in the disreefing between the two main parachutes was successfully demonstrated validating the main parachutes for the maximum design.

The test evaluated the system's structural integrity and load distribution under asymmetric disreefing conditions, which is one of the most critical load scenarios expected during actual mission descent.

A simulated mass equivalent to the Crew Module was dropped from an altitude of 2.5 km using the Indian Air Force's IL-76 aircraft. The parachute system deployed as planned and the sequence was executed flawlessly, and the test article achieved a stable descent and soft landing, validating the robustness of the parachute design.
