If you want to extract useful materials from asteroids, you should: automatic closed-loop enterprise. Would offer an option:Delivery module. The module is being introduced to the surface. Telemetry control robots to find no need for drilling locations. After finding the robots are already automatically convey the ore to the mill. after remelting and packaging materials, to the launch site and along the orbit of Jupiter to orbit the Earte or or direct route. Earth orbit packing large lot in the descent module. Delivery to the surface and rebounding. True, I have no idea what means does it take to create it in one lifetime. If you have such finance, even with them, it will take about 20 years.Require about 30 programmers, 10-18 engineers metals and alloys, 8 chemists and useful ideas. In addition to the number of staff you still have to pay not only the design, but also materials for assembly. You really possess such means? This is not an idle question. Since this idea was born in the USSR, but has not received strength. However, this is the only way of survival.
