Scientists have detected more than 40 ice-filled craters in the moon's North Pole using data from a NASA radar that flew aboard India's Chandrayaan-I.
NASA's Mini-SAR instrument, lightweight, synthetic aperture radar, found more than 40 small craters with water ice. The craters range in size from 2 to 15 km in diameter.
The finding would give future missions a new target to further explore and exploit, a NASA statement said, adding it is estimated that there could be at least 600 million metric tons of water ice in the craters.
