New Delhi: The Gaganyaan IADT-02 test marks another major milestone for India’s human spaceflight mission. ISRO has successfully completed the second Integrated Air-Drop Test (IADT), focusing on validating parachute and recovery systems for the crew module.
Conducted over the Bay of Bengal near Sriharikota, this test ensures that astronauts can safely return to Earth after space missions. With this achievement, ISRO moves one step closer to making India a human spaceflight-capable nation.
What is the Gaganyaan IADT-02 Test?
The Integrated Air-Drop Test (IADT-02) is a crucial experiment designed to test how the crew module behaves during re-entry and landing.

It checks whether:
- The parachute system works properly
- The module slows down safely
- The splashdown in the sea is controlled
This is the second such test, following the first one conducted in August 2025.
How the Gaganyaan IADT-02 Test Was Conducted
The test was carried out in a carefully planned sequence:
- A Chinook helicopter lifted the crew module
- The module, weighing 5.7 tonnes, was dropped from 3 km altitude
- The drop happened over the Bay of Bengal near Sriharikota
After release:
- Small drogue parachutes deployed first
- Then main parachutes opened to reduce speed
- Finally, the module made a soft splashdown in the sea
This entire sequence was automatic, simulating real mission conditions.
Why Gaganyaan IADT-02 Test is Important
The Gaganyaan mission aims to send Indian astronauts into space and bring them back safely.
This test is important because:
- It validates crew safety systems
- Ensures controlled landing in water
- Tests real-world emergency scenarios
- Builds confidence before human missions
Without successful recovery systems, human spaceflight is not possible.
What Makes Gaganyaan Unique
Gaganyaan is India’s first mission to send humans into space using an Indian rocket and systems.
Key highlights:
- Fully indigenous technology
- Focus on crew safety and reliability
- Multiple tests before actual launch
- Designed for low Earth orbit missions
Progress So Far
ISRO has been steadily advancing through multiple test phases:
- Abort tests for emergency escape
- Crew module recovery trials
- Environmental and parachute validation tests
The Gaganyaan IADT-02 success confirms that ISRO is progressing in the right direction.
What Comes Next?
After this successful test, ISRO will:
- Conduct more high-altitude and complex tests
- Integrate full mission systems
- Prepare for uncrewed test flights
- Move towards the first human mission
