The TV-D1 mission of October 2023 was conducted mainly to test which system of Gaganyaan?
- A.The cryogenic upper stage
- B.The crew escape system
- C.The docking mechanism
- D.The lunar lander legs
Correct answer
Explanation
The correct answer is B, the crew escape system. TV-D1, the first test vehicle abort mission, was launched from Sriharikota on 21 October 2023. A single stage test vehicle carried the crew module and the crew escape system to about transonic speed, the abort was commanded, the escape motors pulled the crew module clear, and the module came down under parachutes and was recovered from the sea.
Option A is wrong because the cryogenic stage was not part of the test vehicle at all. Option C is wrong because docking is being proved separately, notably through the SpaDeX experiment, and is not part of the first Gaganyaan flight plan. Option D is wrong because a lunar lander belongs to the Chandrayaan programme and has nothing to do with this test. An earlier pad abort test in 2018 had already shown the same escape system working from a stationary rocket on the pad.
