The Grand Canyon was created shortly after a massive asteroid impact.

The vast collision crater near the month of the moon was formed on an asteroid that moved in more than 1 kilometer for 1 second or more, and released 130 times the energy of all existing nuclear weapons. Currently, researchers say that two unusual and straight gorge were formed within 10 minutes by a secondary debris chain of two unusual and straight gorge.

David King In Houston, Texas, and the planetary research institute, we investigated a 312 kilometer Schreading Glator for 15 years. Part of it was to develop a landing site that could have a NASA concertation program. This tried to return people to the moon, but ended in 2009.

“They are basically hidden and in a sense mysterious. [of the moon]King says. “And they are generally overlooked.”

For more information, Kring and his colleagues are using a computer model to investigate the origin of two gorgees or “light rays” extending north from the crater. One is VALLISSCHREDINGER, 270 km long, 2.7 km in depth, 280 km in length and 3.5 km in depth. For comparison, Arizona's Grand Canyon length is 446 km and depth of 1.9 km.

However, it has been engraved in water for millions of years, but the gorge of the moon is a straight and straight groove formed by vast shocking force within 10 minutes. The dramatic asteroid strike not only spread dust and tile BLE throughout the moon, but also spread to space and earth.

Researchers also suggest that the main ones that cause the main crater of the main, faster, to drive the fragments that run through the moon, focusing on narrow areas due to the irregularity of Legoris, which is a loose material that covers the moon. It may have been combined.

Using their models, researchers have calculated that asteroids collide 3811 billion years ago to create the speed and direction of debris to create a gorge. 。

“There is a rock that hits 2 kilometers per second per second, perhaps 2 kilometers per second, and it may be devastating,” says Kring. “I knew that Schrödinger's impact would create these rays, but the related process needed some attention.”

Kring is not deep enough at any of the landing points that Legolis, who was kicked out of Schrölinger, was sued to seriously interfere with geological experiments, so Kring is the moon in the ARTEMIS III mission of NASA. He says that he has a sense of security to put an astronaut in. 。 If they were planning to land north of Schledinger, where much more materials landed, they would have faced a very deep layer that hid the early geology.

Mark Birchel At Kent University in the UK, this study is done in some way to prove that the gorge is formed by a shock chain, but it is necessary to investigate up close.

“The ultimate evidence is the person who brings back the rocks from one or some rocks in these gorgees,” says Birchel. “Then there is a mineral grain that you just cut out, and was shocked there. [by impacts]And some of them have changed the structure as a result. “
