PYRAMIDS ON MARS?

1. An examination of some of the photos of Mars sent back to Earth by the space researchers Mariner-9 and Viking-1 provokes a question: was Mars once an inhabited planet. A group of Russian scientists from a number of organizations examined the photos and made their conclusions.

2. There were discovered formations which have been interpreted as "a field of quadrangular pyramids". Mariner-9 discovered formations which are geometrically correct structures. Viking-1 photographed something resembling the ruins of Egyptian pyramids. Nine kilometres east of the "city of pyramids" the photograph shows a stone structure shaped like a human head, and a strange dark circle.

3. The analyses and physical modelling 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 of the Bermuda Island 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 kilometres per side at the base and up to one kilometre 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 to a head. But all these strange figures are of natural origin.
