Meteor Crater in Arizona
• Meteor Crater in Arizona
Meteor Crater - one of the most famous places on the planet where you can see the effects of the Earth's collision with another celestial body. This crater is one of the biggest, but because it is often removed in scientific and documentary films, and in 1960 before going to the moon, astronauts are trained NASA.
The great depression 1,220 meters and 230 meters of depth resulting in the collision of the planet with an iron meteorite with a diameter of about 50 meters and weighing more than 300 thousand tons, flying at a speed of 45-60 million km / h. It happened about 50,000 years ago.
Edge Arizona crater rises above the plain to 46 meters.
The explosion of fall was three times more powerful than the Tunguska explosion was similar in explosive power of 150 million tons of TNT, or 8,000 atomic bombs similar to those dropped on Hiroshima.
Prior to the beginning of the XX century it was believed that the crater in Arizona was formed by volcanic activity, but in 1902 the hypothesis of its cosmic origin of advanced engineer Daniel Moreau Berrinzher, who bought the land and began to spend there research to prove their case.
26 years, scientists have spent searching for the remnants of a meteorite, but found nothing. It was not until 30 years after his death and a planetary geologist Eugene Shoemaker was able to prove the cosmic origin of this basin.
Meteor Crater was found a place in the world to the greatest extent reminiscent of a lunar landscape, and it was there under the leadership of Shoemaker were all part of the preparation of the astronauts, who were to go on a mission to the moon.
Now the land is still owned by the family Berrinzhera.
