Asteroid Mining: A Gold Mine In Space
Mining asteroid for rare and precious metals is not a sci-fi dream anymore. Several space mining companies are already preparing for an out-of-this-word gold rush – mining asteroids for important resources needed to construct space colonies, spacecrafts and other things humanity needs to survive. Those massive celestial rocks contain materials like iron, nickel, cobalt, platinum and many others. A single asteroid, depending on the composition, could possibly be worth multi-trillion dollars of raw materials. And Scientists have discovered nearly 15,000 of them are closer to Earth. The data below visualize the big business of asteroid mining. See also the Anatomy of a Comet and the 29 Space Missions Beyond Earth: Where Are They Now?
