ISRO, NASA team up to locate water-ice on Moon

The Moon’s relatively unexplored North Pole became the subject of a unique joint experiment by the National Aeronautics and Space Administration (NASA) and the Indian Space Research Organisation (ISRO) in their quest for locating water-ice on the floor of its permanently shadowed craters.The Mini-SAR (Miniature Synthetic Aperture Radar) on board Chandrayaan-I and the Mini-RF (Miniature Radio Frequency) on the LRO, both developed by NASA, are designed specifically to detect water-ice on the Moon’s poles.
At 00.30 hours on Friday, the two spacecraft, travelling at 1.6 km per second, passed close enough to each other so that they could share information.
