The long-standing theory of the moon being bone dry is now all wet. That's because large swaths of the lunar surface are saturated with water. A trio of satellites, including India's recently lost lunar probe, Chandrayaan 1, picked up the light signature of water or hydroxyl or both while mapping the moon. But don't go planning a lunar pool party just yet. The water on the moon are bound to other molecules and exist in trace amounts over the entire lunar surface. Still, scientists estimate there is about a quart of water for every cubic yard of lunar soil!!!
