Why Chandrayaan Mission 2?

The $142 million Chandrayaan-2 is India's second lunar mission after the country's success with Chandrayaan-1, an orbiter launched 2008 that helped discovery the presence of water molecules on the moon. The new mission will also use an orbiter to study the moon from above, but will also drop a lander and rover to touch down at the south pole of the moon something no spacefaring nation has ever done before. If successful, India would become the fourth country (after the United States, Russia and China) to successfully soft-land a spacecraft on the moon, and the first to reach the lunar south pole. The moon's south pole is a tantalizing target for scientists as the region's permanently shadowed craters can host water ice, a vital resource for future astronauts.
