68 Meteorites (1/2)
The fireball dragged the long fireworks tail and crossed the sky from south to north.
The horizon rises with a huge flame, the earth begins to tremble, and the virgin forest of more than a dozen square kilometers is knocked down by the shock wave.
The sky after the explosion was shrouded in a gloomy orange.
The place where the fireball hits left a funnel-shaped pothole.
The potholes form a lake.
This lake is Chen Rui who looked down on the top of the mountain yesterday and saw a very regular circular lake.
The fireballs painted on the rock paintings of the indigenous ancestors are the meteorites.
The fireball dragged the long pyrotechnic tail because the meteorite entered the earth atmosphere and burned with the atmosphere air under high-speed, intense friction, forming a fireball and a long fireworks tail dragged by the fireball.
Most of these meteorites come from the asteroid belt between Mars and Jupiter, and a small part comes from the Moon and Mars.
Most meteorites burn and disintegrate when they enter the atmosphere, but there are still about 500 meteorites that fall from marbles to basketball size every year.
A very small number of meteorites are large enough to fall on the ground, because the impact is equivalent to a dozen times the bullet speed and powerful kinetic energy of more than a dozen kilograms or even tons of mass-produced a huge impact crater. But, many meteorites are small in size, when they fall to the ground, they have reached the terminal speed. At most, they can only create a small hole.
The meteorites that were recorded long ago on the rock paintings of the indigenous ancestors hit the ground.
The horizon caused a huge flame, the earth was shaking, and the virgin forest of more than ten square kilometers near the center was knocked down by the shock wave, and a crater with a diameter of 300 meters was left behind.
It can be explained that the head of this meteorite is very huge.
Because it is in the depths of the Amazon rainforest, it is inaccessible, and the local indigenous people do not know the value of the meteorite. Perhaps it is just an ordinary stone. Perhaps the lake produced by the 'God' subconsciously fears in the bottom of the heart. So they did not salvage the meteorites from the bottom of the lakes.
Therefore, Chen Rui concluded that the meteorite is likely to remain at the bottom of the lake.
Chen Rui decided to sneak into the lake to salvage this valuable meteorite.
The value of meteorites is that they are scientific samples of 'cheap and good quality'.
Imagine that to retrieve samples from other planets, you need to use a spaceship, which is huge and amazing!
The Apollo spacecraft landed on the moon, costing hundreds of millions of dollars, only collecting more than 300 kilograms of lunar surface samples from the front of the moon, still cannot obtain samples of the moon far from the surface of the earth, but if you can pick up the meteorites that came from outer space in Earth, the cost is absolutely less.
The facts show that in the Antarctic Continent, because it is an uncultivated place and a virgin land, the meteorites are best preserved. For example, among the meteorites found in the Antarctic continent, there are 9 meteorite samples from the moon. What is more precious is that 8 of them are meteorites that came from the back of the moon.
It is more difficult and costly to collect samples on Mars than on the moon.
These meteorites carry the original information of celestial bodies and are of great significance to human studies in high-energy physics, celestial evolution, geochemistry, and the origin of life.
For example, humans have found a large amount of organic matter such as ammonia, nucleic acids, fatty acids, pigments and 11 kinds of amino acids in meteorites with high carbon content.
