As we all know, a simple look at the surface of Mars is enough to start "seeing things". Numerous videos posted on YouTube by people ready to swear that they saw Martian rabbits -- even in some cases dead Martians -- attest to that. I do not wish to become a member of that elite club. Nonetheless, I must take my chance and show you these pictures of two (2) objects which appear to be anything but natural. I will gladly concead that it could be the result of my imagination gone wild, but the first object, circular and quite large, looks like a very big wheel, with what seem to be an exhaust pipe coming out of the back of it, and what looks like an attachment part at the front. In close proximity to this object, we find a larger pipe placed vertically in the soil. The original image, of a region of clay, was published recently on Nasa' site.
