The influence of small asteroid on the moon exploded within 10 seconds. Two Grand Canyon

Washington (Reuters) -The Grand Canyon in Arizona is one of the natural wonders of the earth. It has carved millions of years through the gradual erosion power of the Colorado River. There are two canyons near the moon, and the size of each canyon is equivalent to the size of the Grand Canyon.
The new research shows that these canyons on the side of the canyon on the canyon called Schrödinger, crossing the side of the earth, and when the rock fragments were dug out of asteroids or comets in less than 10 minutes, the rock fragments violently emitted out violently. Essence The surface of the moon was about 3.8 billion years ago.

According to the chief authors of the research published in the magazine of Natural Communications on Tuesday, this influence released 130 times the current global nuclear weapon inventory. Essence
Scientists use the data obtained by NASA’s robotic lunar reconnaissance rail spacecraft to draw the canyon, and then use computer modeling to determine the flow direction and speed of flying fragments. They found that the rubble can reach about 2200 miles per hour (3,600 kilometers) per hour.
One of the canyons called Vallis Planck is about 174 miles (280 kilometers) long and 2.2 miles deep (3.5 kilometers). The other is Vallisschrödinger, about 168 miles (270 kilometers), and 1.7 miles deep (2.7 kilometers).
This impact occurred during the heavy bombardment of space rocks in the internal solar system, because of changes in space rocks, and the orbit of giant planets in the solar system changed-Jupiter, Saturn, Uranus, and Neptune-thought of time.
It is estimated that the diameter of the object that hit the moon is about 15 miles (25 kilometers), which is larger than the asteroid 66 million years ago, and it is doomed to dinosaurs.
“When the impact asteroid or comet hit the surface of the moon, it excavated a lot of rocks that were launched above the moon before the moon fell. The smaller impact effectively carved the canyon.
The canyon is a straight scar on the surface of the moon. It extends from large and circularly impacted volcanic mouths, and there is a small crater nearby.
This marks one of the last impacts on the moon and the earth’s surface during the bombing of the early solar system. The moon still has these scars on its surface, and there is no earth.
That is because the earth recycle its surface into part of the geological process, called the plate structure. The outside of our planet is composed of rocks on the size of the mainland, and the movement of these rocks is very slow. At the place where they met, one plate dived under the other plate and sent the rocks to the rocks below. The moon, the smaller body lacks the plate structure.
In the next few years, the new discovery is related to the moon exploration. Schrindingerimpact Basin is located near the ARTEMIS MISSION’s exploration area in NASA. It aims to put astronauts on the moon for the first time since Apollo landed in the 1970s.
“Because the fragments of Schrgdinger’s impact were abandoned the Moon Antarctic, the ancient rocks in the polar region will be near the ground, where Artemis Arthemis Astronauts will be able to collect them. Therefore, for astronauts, astronauts will be easier. In the earliest, The lunar historical era collects samples, “Klin said.
These rocks will enable scientists to test a hypothesis, that is, when large impactters collide with the earth and send meliomas into space, and assuming that the moon will produce the moon when the moon surface is an early ocean of magma.
