A piece of Mars: These large dunes are located in Kaiser crater, a big crater in the southern midlatitudes. The scene is 789×592 m across. Imagine standing on one of these monsters, and seeing nothing but pristine ripples criscrossing all over the place. (HiRISE ESP_029500_1330, NASA/JPL/University of Arizona)

Very nice! Did you make that?
This picture looks like blue sand with lighting crystals – beautiful. Yeah imagine that – what an adventure!
The sand isn’t really blue, it’s more grayish. But I like to draw out the colors. Even a dark gray would be pretty exotic.
