"These are, quite simply, the coolest planetary maps I’ve ever seen. I didn’t know that the United States Geological Survey even mapped planets in the first place. But indeed they do. The map above — of the moon’s dark side, with colors correlating to geological materials and phenomena — is one of a series produced in partnership with NASA between 1971 and 1998." The color scheme here is really cool - it's more like a painting than a map.
