Since then, researchers have been trying to make sense of finger-like rock structures splayed across the landscape. The working hypothesis at the time was that these rocks started out as continuous layers but eroded into odd shapes by the touch of wind and sand over the years.

The photos from the Mar’s rovers look almost like the high desert of the American West, but remember  that Mars has only 1/100th of our atmosphere, and the temperature is well below zero most of the time. However, and this is key- when we …
