The Indian Space Research Organisation (Isro) has successfully completed a crucial parachute test for the Gaganyaan human spaceflight programme, bringing India one step closer to safely bringing its astronauts back to Earth.
Isro announced that it conducted the Integrated Main Parachute Airdrop Test (IMAT-05) at the Aerial Delivery Research and Development Establishment (ADRDE) drop zone in Sheopur, Madhya Pradesh.
The test was aimed at validating the performance of the main parachute system that will play a critical role in slowing the Gaganyaan crew capsule before it splashes down in the sea.
The parachute system is one of the most important safety features of the mission. During re-entry, the crew module will hurtle through Earth’s atmosphere at tremendous speeds before relying on a carefully choreographed sequence of parachutes to reduce its descent to a safe landing speed.
The Gaganyaan Crew Module’s deceleration system consists of 10 parachutes of four different types. The sequence begins with two Apex Cover Separation parachutes, which remove the protective cover over the parachute compartment. This is followed by the deployment of two Drogue parachutes, which stabilise the capsule and reduce its speed.
Once the module is sufficiently stabilised, three Pilot parachutes are deployed to extract three Main parachutes. These large canopies provide the final stage of deceleration, slowing the crew module enough for a safe splashdown in the ocean, where recovery teams will retrieve the astronauts.
For the latest test, engineers dropped a simulated main parachute assembly attached to a dummy mass from an altitude of 2.5 kilometres using an Indian Air Force IL-76 transport aircraft.
The test began with an extractor parachute, which deployed a drogue parachute to stabilise the payload. After the required flight conditions were achieved, the main parachute deployed successfully, slowing the payload to a safe terminal velocity.
According to Isro, the objective was to qualify the main parachute’s structural integrity and design margins under the maximum expected load conditions that could occur during the first uncrewed Gaganyaan G1 mission.
The successful trial marks the fifth Integrated Main Parachute Airdrop Test (IMAT-05) in the qualification campaign. Isro said the result provides confidence in the performance and reliability of the main parachute system ahead of the G1 mission.
The test was conducted through the combined efforts of Isro, DRDO, the Indian Air Force and the Indian Army, highlighting the multi-agency collaboration behind India’s first human spaceflight programme.
The G1 mission, the first uncrewed test flight of Gaganyaan, will validate critical systems before Indian astronauts are launched into orbitmaking the parachute system one of the final lines of defence in ensuring a safe return from space.
