Moon mineralogy mapper, which is also known as M3 was one of the most successful payloads from Chandrayaan-1. M3 from the Brown University and JPL was an imaging spectrometer designed to map the surface mineral composition. It confirmed the traces of water vapour, which was a significant contribution of the Chandrayaan-1 mission.
The primary objective of the Chandrayaan-2 mission is to find water on the lunar surface, which is backed by ‘the thousands of tests’ conducted by the agency. Landing the Chandrayaan-2 will be one of the major concern of the space agency, ISRO. The mission carries 13 Indian scientific instruments for conducting experiments
