Answer

B. They are designed to significantly reduce the recurring costs of satellite deployment

Show ExplanationHide Explanation

Explanation

Reusable Launch Vehicles (RLVs) are engineered to recover and reuse major rocket components, such as first stages or spaceplanes, thereby lowering launch costs, increasing launch frequency, and improving sustainability. This concept was advanced by programs like NASA’s Space Shuttle (first launch: 1981) and modern systems such as SpaceX’s Falcon 9 (first successful landing: 2015). In India, ISRO’s RLV-LEX autonomous landing experiment (2023) demonstrated key reuse technologies.
