PYRAMIDS ON THE MARS?
1.     An examination of some of the photos of the Mars sent back to the Earth by the space researchers Mariner-9 and Viking-1 provokes a question: was еру Mars once an inhabited planet? A group of Soviet scientists from a number of organizations examined the photos and gave their conclusions.
2.    There were discovered formations which had been interpreted as "a field of quadrangular pyramids". Mariner-9 discovered formations which were geometrically correct structures. Viking-1 photographed something resembling the ruins of Egyptian pyramids. Nine kilometers east of the "city of pyramids" the photo-shows a stone structure shaped like a human head, and a strange dark circle
3.     The analyses and physical modeling of the Martian formations were performed. The Martian surface was compared with that of the Moon, and the shapes of the formations were compared with those of Egyptian and Mexican pyramids. The small Martian "pyramids" were found to resemble the recently discovered giant pyramids, lying on the seabed near the Bermuda Islands and the pyramids, 250 m high, found in the Brazilian jungle.
4.     But they are nothing in comparison to the large Martian "pyramids" measuring up to 1.5 kilometers per side3 at the base and up to one kilometer in height. The image of the "Martian sphinx", 1.5 km long and 0.5 km wide, lies strictly along the meridian of the planet.
5.     In the opinion of experts, the photographed formations are indeed pyramid-shaped, and the oval shaped formation bears a formal resemblance to4 a head. But all these strange figures are of natural origin.
