Explore the universe on the one hand to satisfy human curiosity. At the same time, people are also keen to benefit from deep space resources.
"From now on, humanity has carried out more than 200 deep space exploration activities. The use and development of space resources has become a global hot spot, and the asteroid retirement period is coming soon." Yang Zhen, researcher at the Chinese Science Academy National Space Science Center, said.
Asteroid is a celestial body in the solar system similar to a planet that outweighs the sun but has a volume and mass much less than a plan. Asteroids closer to Earth are known as asteroids near Earth. In addition, there is an asteroid belt between Mars and Jupiter, and about 90% of asteroids are known in the asteroid belt.
Although they are small, their number is huge. It is estimated that millions of asteroids are probably in the solar system. For asteroids, people do not know enough about it. "There are more than 60% of asteroids, we have not had detailed speculative data, some of which have even glasses data, but it's not just about the composition of the area that its analysis is, and it does not know its internal composition. " Yang Zhen noted that at present many rarely or valuable metals on asteroids have some arguments.
But the results of the introductory observations also make people exciting. Scientists estimate that Amun, the asteroid 3554 with a diameter of about 2.5 kilometers, could be worth more than $ 20 trillion of platinum and other metal deposits. The 16-kilometer 25-kilometer asteroid, whose mineral value is considered a astronomical figure: $ 1019.
If you want to establish asteroids, the "early" examination is essential. In fact, the United States, Europe and Japan have all their own asteroid examination programs, and some audited projects have. More and more small and medium-sized countries intend to carry out deep space audit projects. At the same time, more and more capital and private enterprise companies focus on deep space exploration, with the aim of mining and using asteroid resources. This means that the period of asteroid colonization comes.
