At a large press conference in Moscow, Russia, Russian space expert Yute Posov announced an amazing news: an unmanned spacecraft sent by the Soviet Union to explore Mars suddenly lost all news after shooting a strange warning sign from the desolate surface of Mars on March 27th, 1990. Some scientists speculate that it may have been destroyed by Martians.

This warning sign says "Leave" in English. Judging from the photos sent back by the radio, this huge sign seems to be carved out of stone. Proportionally, these two words are at least half a mile long. The slogan seems to be carved from a huge rock, and from its smooth surface, it may have been cut by laser. When the American Viking 1 spacecraft explored Mars in 1976, it can be clearly seen from the photos taken over the desert area in the mountainous area of San doria that a huge stone statue with complete facial features stands on a high mountain, which is 16 kilometers long from the top of the head to the chin. The width of the face and heart is 14km, which is very similar to the Sphinx in Egypt. The statue looks like looking up at the sky and meditating. After a lapse of 20 years, 1996, the American "Mars Observer" spacecraft, which was surveying and mapping in the orbit of Mars, flew over the "Mars face" area and took a clearer picture. Compared with 1976, this picture enlarges the "Martian face" by 10 times. Scientists have found that these stone statues have been eroded by wind and rain for many years. And this slogan is not as old as the mysterious face photographed on Mars by the American spacecraft Viking 1. This warning slogan seems to have appeared only recently.

Why do Martians write such two words? Dr. Posov said: "It is obviously aimed at the people of the earth. I think it must be because we sent too many Mars spacecraft and disturbed the peace of life on Mars, so we issued this warning and told us to leave. "

Dr. Bosov revealed that the spaceship they sent went smoothly at first, but when it sent the warning photos back to Earth, it mysteriously disappeared. It is not clear whether the spacecraft was destroyed by life on Mars or temporarily detained by them. He said: "If we contact those Martians by radio first, and then send people to their planet to establish diplomatic relations with them. I think they will accept it. "

The content published by Dr. Bosov immediately shocked the western scientific community, and many scientists thought it was the greatest discovery in the history of human space exploration.
