Which ISRO mission first discovered lunar hydration?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. Chandrayaan-1.
Launched in 2008, Chandrayaan-1 was India's first mission to the Moon and is credited with the groundbreaking discovery of lunar hydration (water molecules and hydroxyl). This was achieved using the Moon Mineralogy Mapper (M3), an instrument provided by NASA. The data revealed evidence of water in the lunar soil and thin atmosphere, shattering the long-held belief that the Moon was a completely dry celestial body. This discovery fundamentally changed lunar science and paved the way for future exploration missions like Chandrayaan-2 and 3.
