Utilization of the asteroid subject on the moon - а more economic way to obtain cosmic resources of high value

In recent years, in analytical reviews, experts are increasingly paying attention to the growing scarcity of rare and rare-earth elements necessary for the development of advanced technologies in modern industry. To solve this problem, in the future, projects were proposed for the utilization of a substance of asteroids approaching the Earth. Despite the difficulties of seizing, transporting and further developing such an object in space, this way of solving the problem seemed technologically feasible and cost-effective justified. A 10-m iron-nickel asteroid could contain up to 75 tons of rare and rare-earth metals, primarily platinum-group metals, which is equivalent to a commercial price of about $2.8 billion in 2016 prices. In this paper it is shown that the utilization of an asteroid substance entering the lunar surface can be technologically more simple and economically more cost-effective. Until now, it was believed that the lunar impact craters do not contain the rocks of the asteroids that formed them, since at high velocities the impactors evaporate during a collision with the lunar surface...
