Martian Racetracks
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."
I, for one, welcome our new Nascar Martian Overloads.
"Comb the desert!~!!" "We ain't found shxt!!"
The Martians were as crazy about Nascar as we are.
