Meteorit Crater

Today we had our second coldest day (after the snowstorm in Wyoming).
We went to the world's best preserved meteor crater, where we saw an interesting exhibition on meteors, and then had a small tour to the crater. In the middle of nowhere, on a complete flat landscape, so nothing stopped the ice cold wind. We were told some incredible facts about the meteorite: the meteorite was flying 20 km/s before the impact, which had a power of the explosion of 20 million tons of TNT, leaving a 200 meter deep crater.
In the 1900's the meteorite was believed to still be under the crater, so they started drilling and got to 400 m deep, but found nothing. They were looking for a huge iron meteorite, worth more than a billion dollars back then, and invested around 7 million dollars (today's value). Nothing has ever been found, as the meteorite evaporated at the impact.
NASA had its training station for the Apollo Program in the crater, as it is so moon-like.もっと詳しく
