Mars: Mysteries and curiosities about the red planet

These are some pictures that in my opinion are to be taken into consideration when analyzing Mars' history and surface, I know that there are other pics going around in the Internet about humanoids, faces and whatnot, but I usually don't give too much importance to such stuff, which is usually hyped up and spread around just to cheaply get views and hits on websites. I try to keep it rational.
