Sands on Earth, sands on Mars
Some of the low, sandy ripples observed by the Mars Exploration Rover Opportunity in Meridiani Planum (left) bear a striking resemblance to low, sandy ripples seen in Great Sand Dunes National Park and Preserve (right). The scales of these two images are about the same, with the average distance between ripples being 1 to 2 meters.
