Overview

The first step of man to using of outer space, as an economic target, began in 1962, by launching a satellite to transmit television signals between Europe and North America. The resources needed from space, comprise water, regolith, metals, minerals, non-metals, together with atmospheric gases. However. by 2010, about 31% of all space launches were commercial. It is believed that the resources of the solar system are virtually unlimited compared to those of Earth, being embedded in other planets, moons, massive asteroids, and small planets as well, that doubtless contain huge quantities of materials that are scarce on Earth. Space scientists foresee that, heavy industry is on the move to space, to free the Earth for becoming a healthy residential area.
