If this was posted somewhere else i apologize... Apparently they have an "idea" of how those ripples on Mars formed.




The nature of strange ripples of sand on the Martian surface is clearer now thanks to pole-to-pole images returned by a NASA spacecraft. But even with this new information, scientists still are unsure just how the features, which are unlike anything on Earth, came to be.





Called Transverse Aeolian Ridges (TARs), these unusual features are formed by wind-driven particles (phenomena involving air movement are known as "Aeolian processes"). The winds blow the ridges into many shapes: simple ripples, forked ripples, snake-like sinuous waves, crescent shapes and complex, over-lapping networks
