ISRO Successfully Completes Air-Drop Trial for Gaganyaan Safety

Nagpur, August 25, 2025 - In a landmark advancement for India’s human spaceflight ambitions, the Indian Space Research Organisation (ISRO) successfully completed its first Integrated Air-Drop Test (IADT-01) of the parachute deceleration system designed for the Gaganyaan mission. This test is a joint effort of ISRO, Indian Air Force, DRDO,Indian Navy and Indian Coast Guard. Conducted early Sunday at its Sriharikota spaceport, this critical exercise validates the parachute system meant to safely return astronauts to Earth.

According to official sources, the test was executed using a mock module released from an Indian Air Force aircraft. The system performed flawlessly, deploying in sequence as planned—from cover separation to drogue and finally main parachutes—ensuring controlled descent and soft landing of the payload.

Notably, this integrated air-drop trial marks a significant milestone for Gaganyaan—the nation’s first crewed spaceflight mission. It affirms ISRO’s preparedness and bolsters confidence as the organization advances toward uncrewed and eventual crewed missions.

What This Test Means

Safety Validation: The test confirms that the parachute system—including the vital sequence of parachute deployment—functions reliably under real-world conditions, a must for ensuring astronaut safety.

Mission Progress: As one of the final key preparatory steps, this success paves the way for upcoming unmanned test missions and lays the foundation for the fully crewed launch in the near future.
