Concept:The RLV-LEX3 test proved ISRO’s ability to autonomously land a reusable launch vehicle at high speed despite challenging wind and cross-range conditions – a critical step for reusability.
Explanation:ISRO’s Reusable Launch Vehicle – Landing Experiment (RLV-LEX) was carried out on June 23, 2024.
The test focused on achieving a fully autonomous high-speed landing under difficult cross-range and wind conditions.
The RLV was released from a helicopter at an altitude of 4.5 km and then navigated itself to land on an airstrip at high speed.
This autonomous landing capability is essential for making launch vehicles reusable, which lowers satellite launch costs and improves efficiency.
The other options – fuel transfer during hypersonic flight, crewed abort tests, or scramjet satellite insertion – were not part of this experiment.
Thus, the key technological success is the demonstration of fully autonomous high-speed landing under adverse conditions.
Answer:B. Fully autonomous high-speed landing under difficult cross-range and wind
