Exploring the universe is, on the one hand, to satisfy human curiosity. At the same time, people are also keen to take advantage of deep space resources.
"From now on, humanity has carried out more than 200 deep space exploration activities. The utilization of space resources and development has become a global hot spot, and asteroid colonization is coming soon." Yang Zhen, researcher at the National Science Center of the Chinese Academy of Sciences, told reporters.
An asteroid is a celestial body in the solar system resembling a planet that circles the sun but has a much smaller volume and mass than a planet. Asteroids that are closer to the Earth are called near-asteroids. In addition, there is an asteroid band between Mars and Jupiter, and about 90% of the known asteroids are found in the asteroid band.
Even though they are small, their numbers are enormous. It is estimated that there are probably millions of asteroids in the solar system. For asteroids, people do not know enough about it. "More than 60% of the asteroids, we have not received detailed spectral data about it, and some also have spectral data, but the analysis of it only remains on the surface composition and does not know its internal composition." Yang Zhen pointed out that at present If there are many rare resources or precious metals on the asteroids, it still has some controversy.
But the results of preliminary observations also make people excited. Researchers estimate that Amun, the 3554 asteroid with a diameter of about 2.5 kilometers, can contain more than $ 20 billion of platinum and other metal deposits. The 252 kilometer long asteroid 16-Psyche, whose mineral value is considered an astronomical figure: $ 1019.
If you want to colonize asteroids, the early "exploration" is crucial. In fact, the US, Europe and Japan all have their own exploration programs for asteroids, and some prospecting projects have been implemented. More and more small and medium-sized countries are planning to carry out deep exploration projects. At the same time, more and more venture capital and private companies are focusing on deep exploration, in order to mine and exploit asteroid resources. This means that the asteroid colonization side comes.
