NASA to Explore an Asteroid Containing Enough Mineral Wealth to Collapse the World Economy | Big Think
We think of asteroids as giant useless rocks floating around space. Perhaps it’s a good place to hide the Millennium Falcon or a worrisome cause of a cataclysmic event. Though most are hunks of rock or ice, some are replete with iron, platinum, gold, and other precious minerals. Two NASA missions plan to explore such an asteroid, scheduled for 2021 and 2023. These are part of NASA’s Discovery Program, a class of mission considered inexpensive, capping out at $450 million apiece.
