- 28 Aug 2025
In News:
The Indian Space Research Organisation (ISRO)has successfully conducted its firstIntegrated Air Drop Test (IADT-01) for the Gaganyaan human spaceflight programme, marking a critical milestone in validating astronaut safety systems.
Objective of IADT-01
- Test the end-to-end parachute recovery system of the Gaganyaan crew module.
- Demonstrate reliability, sequencing, and redundancy of drogue, pilot, and main parachutes for controlled deceleration and safe splashdown.
- Ensure astronaut safety during the re-entry and landing phases, considered the riskiest part of any human space mission.
Significance
- Validates a vital safety mechanism for Gaganyaan, boosting confidence ahead of upcoming missions like Test Vehicle-D2 (TV-D2) and the first uncrewedGaganyaan mission (G1).
- Strengthens India’s human-rating capabilities, positioning the country to become the fourth nation with independent crewed spaceflight capability.
- Reflects successful inter-agency collaboration among ISRO, Indian Air Force, DRDO, Navy, and Coast Guard.
Gaganyaan Mission Overview
- Crewed mission scheduled for 2028; uncrewed test flight planned in December 2025.
- Mission profile: Carry a three-member crew to low Earth orbit (~400 km) for up to three days, followed by safe return.
- The programme emphasizes astronaut safety, technological reliability, and operational preparedness, with future tests including additional parachute validations, pad abort trials, and sea recovery rehearsals.
Strategic Importance
- Demonstrates India’s capability in human spaceflight, enhancing its global standing in space technology.
- Paves the way for advanced crewed missions and potential applications in scientific research, space exploration, and international collaborations.
