      Question

      What specific technical capability did ISRO demonstrate

      in the first Integrated Air Drop Test (IADT-1) for the Gaganyaan programme?
      A Heat shield ablation testing in orbit Correct Answer Incorrect Answer
      B Parachute-based deceleration system for safe landing of the crew module Correct Answer Incorrect Answer
      C In-orbit crew life-support provisioning for 30 days Correct Answer Incorrect Answer
      D Launch escape tower separation at max Q Correct Answer Incorrect Answer
      E Autonomous docking with ISS for crew transfer Correct Answer Incorrect Answer

      Solution

      The IADT-1 test demonstrated the parachute-based deceleration system, a critical element for ensuring the safe landing of the crew module during the Gaganyaan human spaceflight programme. The brief explains that in actual missions, parachutes deploy after re-entry, subsequent to deceleration by heat shields and drogue parachutes. The air-drop specifically tests the parachute sequence and deceleration performance essential for human-rating. Options (a), (c), (d), and (e) describe other types of tests or capabilities not stated as part of IADT-1 in the provided information.
