New Delhi: The Indian Space Research Organisation (ISRO) has successfully carried out its first Integrated Air Drop Test (IADT-01) of the parachute-based deceleration system for the Gaganyaan human spaceflight programme.
The test, jointly conducted with the Indian Air Force, DRDO, Indian Navy and Indian Coast Guard, was a crucial step to validate the system designed to ensure astronauts’ safe return from space.

The demonstration evaluated the full parachute suite — beginning with two drogue parachutes for initial deceleration, followed by pilot chutes, and finally three large main parachutes to guarantee a smooth descent and splashdown of the crew module.
ISRO said this success marks a major milestone in the Gaganyaan mission, India’s maiden attempt to send humans to space.
Preparations are also underway for upcoming tests, including the Test Vehicle Demonstration-2 (TV-D2) and the first uncrewed Gaganyaan mission (G1), which will pave the way for the country’s historic human spaceflight.
