The spacecraft operated for less than two years: days as opposed to two years. However, the Chandrayaan-1 was successful in achieving at least 95 per cent of its objectives.

One of its biggest discovery was to find traces of water on the Moon, which was in itself a path-breaking achievement in international space science. Besides this, the spacecraft also found water ice in the North polar region of the Moon as well as detected Magnesium, Aluminium and Silicon on its surface.
