Ancient Runway Found on Mars

Investigating strange structures on cosmic bodies has become quite a global phenomenon in amateur astronomy circles. Structures that seem to be man-made or alien in design are being found and blogged by theorists and shown in video found on Youtube. There is no doubt that these structure are there on the surfaces of the Moon and Mars, but what are they? Some theorists suggest that NASA are not telling the people of Planet Earth everything they know and what NASA are doing technologically. However you look at the images of the structures something is not as it seems.
