ISRO gives Gaganyaan crew module another smooth 'fall test' win

The Indian Space Research Organisation (ISRO) has successfully carried out the second integrated air drop test (IADT-02) for its ambitious Gaganyaan human spaceflight programme at Sriharikota in Andhra Pradesh.

The test marks another key milestone in validating the systems designed to ensure the safe return of astronauts during re-entry and landing. The integrated air drop test is a critical part of mission preparedness, focusing on the recovery mechanism of the crew module, the capsule that will carry astronauts during the mission.

The crew module recovery system is designed to ensure safe landing after atmospheric re-entry, with particular emphasis on parachute deployment, descent stability, and overall landing safety under different emergency scenarios.

Union Minister Jitendra Singh congratulated ISRO on the achievement.

"Congratulations #ISRO for the successful accomplishment of Second Integrated Air Drop Test (IADT-02) for #Gaganyaan, India's first Human Space flight scheduled next year. The second Integrated Air Drop Test (IADT-02) was successfully conducted at Satish Dhawan Space Station Sriharikota," Singh said in a post on X.

The latest test follows the first integrated air drop test conducted on August 24, 2025 at the Satish Dhawan Space Centre in Sriharikota, which had already validated key recovery procedures for the mission.

Air drop tests simulate the final phase of a spacecraft’s return to Earth. In these trials, a spacecraft or a dummy module is released from an aircraft or helicopter at altitude to replicate re-entry conditions and evaluate system performance.

These tests assess critical parameters such as parachute deployment during normal and abort conditions, performance in case of partial system failure, and the stability of the capsule during descent and splashdown.

During the first IADT, a 4.8-tonne dummy crew module was dropped from a Chinook helicopter at an altitude of three kilometres. Following its release, a parachute system comprising 10 parachutes was deployed successfully, slowing the module for a safe splashdown.
