Oxygen and hydrogen, the main component of rocket fuel an be extracted. Why are there so many more of these resources in space than on Earth? In space, and the metals that are mined on our planet are the remains of asteroids. That hit Earth during meteorite bombardment after the crust cooled. Dodies contain more precious metals than the entire earth’s crust. Due to the large mass of our planet and gravity, a significant part of the heavy metals sank to the core. And on most asteroids, whose weight is many times less than the weight of the Earth. The metals are distributed more or less evenly.
It is believed that some of these celestial
Towards the study of asteroids Humanity is still at the China Mobile Number List beginning of this path: we are still getting acquainted with the potential that is hidden in space. The first contact with the asteroid was in 1991 – then the Galileo apparatus passed close to one of these celestial bodies. The first company to explore the possibilities of mining resources in space was Planetary Resources , founded in Washington in 2009. Then other startups appeared: for example, Deep Space Industries . But almost all projects were closed due to lack of funding. In 2010, the first sample of soil from an asteroid was delivered to Earth. This was done by the Japanese apparatus Hayabusa.
All elements heavier than helium appeared
It turned out that most of the material from the surface USA CFO of the asteroid Itokawa consists of the mineral olivine. The second device “Hayabusa-2” in 2020 brought to Earth a sample from the asteroid Ryugu. They found particles of olivine and spinel. of asteroids can be called 2015: it was then that, first in the United States, then in Luxembourg, the UAE, Japan and a number of countries, a law was passed allowing companies to mine minerals on celestial bodies, at the same time a number of startups were registered.
