Indian Space Research Organisation successfully completed the second Integrated Air Drop Test under the Gaganyaan mission from the Satish Dhawan Space Centre

The Indian Space Research Organisation (ISRO) recently successfully completed the second Integrated Air Drop Test under the Gaganyaan mission from the Satish Dhawan Space Centre. This achievement marks a significant step towards India's human spaceflight mission and also demonstrates the development of advanced technology within the country. The Gaganyaan mission is India's first human spaceflight program, aimed at safely sending Indian astronauts into space and bringing them back to Earth. In the tests being conducted under this mission, safety and reliability are being accorded the highest priority. The IADT-02 test was specifically conducted to validate the Crew Module's safe landing system, which ensures the safety of astronauts during emergency situations.

Integrated Air Drop Test

¨   A simulated Crew Module (~5.7 tons, equivalent to Gaganyaan G1) was carried to an altitude of approximately 3 km by an Indian Air Force Chinook helicopter and released into a designated maritime 'drop zone' near the Sriharikota coast.

¨     During the landing sequence, 10 parachutes of 4 different types were deployed in a precise sequence.

¨    These parachutes ensured a gradual reduction in the module's velocity to facilitate a safe touchdown.

¨    The module was successfully recovered with the assistance of the Indian Navy. IADT-02 has validated the parachute-based deceleration system.

¨    This test is crucial for ensuring the safe recovery of the Crew Module, as this is the very module that brings the astronauts back during a human spaceflight mission.

¨     The first test was conducted on August 24, 2025, at the Satish Dhawan Space Centre.

¨     During that instance, a 4.8-ton dummy Crew Module was dropped from an altitude of 3 km using a helicopter. Gaganyaan Mission

¨     The objective of the Gaganyaan mission is to demonstrate human spaceflight capability by launching a three-member crew into a 400 km orbit for a three-day mission, and safely returning them to Earth via a splashdown in Indian territorial waters.

The development of several critical technologies is essential for the success of the mission, including:

A Human-Rated Launch Vehicle for the safe transport of astronauts.

¨     Life Support Systems to provide an Earth-like environment in space.

¨     A Crew Emergency Escape System to rescue the crew in the event of an emergency.

¨   Crew management, which encompasses the training of astronauts, as well as their safe recovery and rehabilitation post-mission.
