This first reversed image shows a number of interesting structures which appear not to be natural. A recent 'expedition' to the Martian surface realised this imagery. It was only when the image was tilted to this final position that the structures contained in the image appear to make more sense.
This second negative image may require double clicking for more clarity. There seems to be water or liquid within the larger crater. The darker area of the crater appears to herald something of interest (Either evidence of technology or life forms). This is again a more recent expedition to the surface of Mars.
