UPSC CDS-2 – 2024
Chandrayaan-3 and Solar Mission Aditya-L1 were major missions of the Indian Space Research Organization (ISRO) in 2023.
In 2023, ISRO successfully launched and executed two highly significant scientific missions: Chandrayaan-3, India’s third lunar exploration mission which achieved a historic soft landing on the Moon’s south polar region, and Aditya-L1, India’s first space-based observatory dedicated to studying the Sun from a halo orbit around the Sun-Earth Lagrangian point L1.
Options 3 (“Liquid fuel powered rockets”) and 4 (“Solar powered rockets”) refer to types of propulsion or non-existent technologies for launch vehicles, not specific missions conducted by ISRO in 2023. ISRO utilizes liquid-fueled rockets (like PSLV stages and GSLV) for its launches, but these are the means of delivery rather than the mission names themselves. Solar power is used by spacecraft in orbit for energy but not for rocket propulsion during launch.
