The Asteroid Miner’s Guide to the Galaxy
To evangelists of asteroid mining, the heavens are not just a frontier but a vast and resource-rich place teeming with opportunity. According to NASA, there are potentially 100,000 near-Earth objects — including asteroids and comets — in the neighborhood of our planet. Some of these NEOs, as they’re called, are small. Others are substantial and potentially packed full of water and various important minerals, such as nickel, cobalt, and iron. One day, advocates believe, those objects will be tapped by variations on the equipment used in the coal mines of Kentucky or in the diamond mines of Africa. And for immense gain: According to industry experts, the contents of a single asteroid could be worth trillions of dollars.
