ISRO Completes Second Integrated Air Drop Test (IADT‑02) for Gaganyaan Mission – Key Milestone for India’s First Crewed Spaceflight
ISRO successfully conducted the second Integrated Air Drop Test (IADT‑02) on 10 April 2026 at the Satish Dhawan Space Centre, validating the parachute‑based deceleration system for the Gaganyaan crew module. The test, involving the Indian Air Force, Navy and DRDO, marks a critical milestone toward India’s first crewed spaceflight slated for 2027, highlighting the nation’s advancing space technology and inter‑agency coordination.
Overview The IADT‑02 was successfully carried out on 10 April 2026 at the Satish Dhawan Space Centre , Sriharikota. The test is part of the Gaganyaan programme, which targets its first human flight in 2027. Key Developments A simulated Crew Module weighing 5.7 tonnes was lifted by an Indian Air Force Chinook helicopter to an altitude of about 3 km and released over the sea. During descent, 10 parachutes of four types were deployed in a pre‑programmed sequence, gradually reducing the velocity of the module. The module was recovered by the Indian Navy in coordination with ISRO, confirming the reliability of the parachute‑based deceleration system . The test demonstrated seamless cooperation among ISRO, the DRDO , the Indian Navy and the Indian Air Force. Important Facts Date: 10 April 2026 Location: Satish Dhawan Space Centre , Sriharikota Test Objective: Validate the parachute‑based deceleration and recovery mechanisms for the crew module ahead of the crewed flight. Mass of simulated module: 5.7 tonnes (same as the actual crew module for the first uncrewed Gaganyaan mission, G1). Parachute configuration: 10 parachutes, four distinct types, deployed sequentially. Stakeholder participation: ISRO, Indian Air Force , Indian Navy, DRDO . UPSC Relevance The successful IADT‑02 underscores India’s growing capabilities in space technology , a key topic under GS‑3 (Science & Technology). It also illustrates inter‑agency coordination (ISRO, IAF, Navy, DRDO), relevant for GS‑2 (Polity) questions on institutional collaboration and national security. The test’s outcome directly impacts the timeline of the Gaganyaan crewed mission, reflecting India’s strategic intent in the global space race. Way Forward Proceed to the final integrated flight test of the crew module, incorporating data from IADT‑02. Complete the certification of all parachute systems and recovery protocols before the scheduled crewed launch in 2027. Strengthen joint operational frameworks among ISRO, the armed forces and DRDO to ensure mission safety and reliability. Leverage the successful test to showcase India’s indigenous space capabilities in diplomatic engagements and international collaborations.
