Chandrayaan 1 made India the fourth country to place their flag insignia on the Moon’s surface, that too on a budget of $56 million (₹386 crore).

Chandrayaan 1 is also famed for being the first to discover evidence of water on the moon with the help of NASA’s Moon Mineralogy Mapper and its own Moon Impact Probe.

Chandrayaan 1’s discovery of water on the moon instigated Chandrayaan 2’s mission to find just how much water is on the Moon and where it’s located.

Chandrayaan 1 was a technology demonstration mission to show that India can reach the moon and had payloads on board from foreign space agencies. Chandrayaan 2, India’s second mission to the moon, was entirely India — from the launch technology to the payloads.

Chandrayaan 1 also made way for India to develop its heavy lift launch vehicle — the GSLV MkIII.
