Sooner or later this always happens... On June 30, 1908, the city of Moscow was nearly destroyed by a huge meteorite - only 4,000 kilometers and 3 hours missed. 4,000 kilometers and 3 hours, how insignificant in the time and space of the universe! On February 12, 1947, the second largest meteorite in the 20th century fell sharply in the direction of Vladivostok (Vladivostok), the Soviet Far East city. The city survived only due to a deviation of 400 kilometers.You know, the destructive power of this object is equivalent to the newly invented uranium atomic bomb at that time! In those days, people could not avoid the attacks of these celestial bodies. If it were not for the protection of the atmosphere, the surface of the earth would have been smashed out of countless craters like the moon by meteorites. The two meteorites in 1908 and 1947, as the very few meteorites that came to the earth, luckily only landed in the desolate wilderness.However, by the end of the 21st century, the Earth has been inhabited from the South Pole to the North Pole, and there is no longer any area where celestial bodies can conduct "bombing exercises".So, inevitably...

On September 11, 2077, at 9:46 GMT on a beautiful summer morning, most of Europe saw a fireball appear in the eastern sky.Seconds later it passed overhead, brighter than the sun.At that time it was silent, only dragging a tail of smoke and dust. Arriving in the sky over a certain place in Austria, the giant began to split apart, and at the same time, it made a huge shock that broke through the sound barrier.The hearing of more than a million people was permanently damaged as a result, and they were the lucky ones. This object, composed of rock and metal, hit the plains of northern Italy at a speed of 50 kilometers per second, destroying the fruits of centuries of human labor in an instant.The cities of Padua and Fornona were swept off the face of the earth, and the waters of the Adriatic flooded the land, burying the glory of Venice forever under the sea.

600,000 people lost their lives, and material losses exceeded 10 trillion yuan.The damage done in terms of culture and science cannot be counted by numbers. The devastating catastrophe shocked mankind.They reacted quickly, that was with determination and solidarity (which would not have been possible in previous years).People realize that this catastrophe may not happen again in a thousand years, or it may happen again tomorrow, and the consequences of the next time...God knows! Then, be determined not to let it happen again! A hundred years ago, it was a much poorer world, with cannibalistic human beings expending its meager wealth of resources trying to intercept and destroy incoming weapons.Such efforts have been unsuccessful, but the resulting technology has not been forgotten.These technologies can now be used for much nobler purposes on a much larger scale, without allowing any meteorite large enough to cause disaster to break through the Earth's defenses.

This is how the Space Guard program began. Fifty years later, the program has proven its worth in ways its founders never expected.
