Please be prepared to be proven wrong. After scrutinizing evidence garnered from various scientific instruments aboard the Chandrayaan, the NASA had last year announced the presence of "little" amount of water on the moon. It was back then, hailed a very significant discovery. A few months down the lane, NASA's Mini SAR probe aboard the Chandrayaan has managed to discover significant amount of water on the moon in an area near the north pole of our closest celestial neighbor. The mini SAR is a very small scientific instrument that weighs less than 10 kgs.
