A new asteroid-mining company launches Tuesday with the goal of helping humanity expand across the solar system by tapping the vast riches of space rocks.

The new firm, called Deep Space Industries, Inc., announced today (Jan. 22) that it plans to launch a fleet of prospecting spacecraft in 2015, then begin harvesting metals and water from near-Earth asteroids within a decade or so. Such work could make it possible to build and refuel spacecraft far above our planet's surface, thus helping our species get a foothold in the final frontier.
