In the near future, commercial opportunities will include the mining of asteroids, comets, the Moon, Mars and Mars’ moons, which represent the most distant supplies of wealth that humankind has ever considered recovering. Obtaining off-Earth resources also has a second, almost priceless sustainable value – they can be recovered without disturbing the Earth.

In the past couple of years, private corporations have shown interest in conducting the direct commercial exploration of minerals on planetary bodies. These companies have aimed to extract minerals mainly from asteroids and the Moon. The first target minerals are water, platinum-group metals and some volatile products such as oxygen, carbon dioxide and hydrogen sulphate....
