Martian Racetracks

Posted by michael on from the because-of-all-the-sandwiches-there dept.

An anonymous reader writes "The European Mars Express spacecraft has released stunning images of 'yardangs': racetrack-like grooves eroded from an otherwise flat plain without obstacles. The terrain in high resolution is shown near the largest volcano in our solar system, Olympus Mons. Notable in the image is an abrupt left turn like the beginnings of a curved terrace."

    Imagine the kind of planet Mars was once. The amount of liquid water once flowing is amazing.
