NOVA | Astroid: Doomsday or Payday?

Posted by WMHT Web Editor on
Asteroid: Doomsday or Payday? Preview Will future asteroids trigger massive extinctions—or be mined for precious minerals?

Watch Wednesday, November 20, 2013 at 9pm on WMHT TV.

The asteroid that exploded in the skies over Siberia injuring more than 1,000 and damaging buildings in six cities was a shocking reminder that Earth is a target in a cosmic shooting range. From the width of a football field to the size of a small city, these space rocks have the potential to be killers. In a collision with Earth, they could set off deadly blast waves, raging fires and colossal tidal waves. But some audacious entrepreneurs look at asteroids and see payday, not doomsday. Some asteroids are loaded with billions of dollars’ worth of elements like iron, nickel and even platinum. While NASA plans an ambitious mission to return samples from a potentially hazardous asteroid, would-be asteroid miners are dreaming up their own program to scout for potentially profitable asteroids.
