Asteroids

The universe is made up of wondrous statistics that detail the incredible range between large and small, near and far, and light and dark – but what any of these inexact terms really describe is still open to debate. We are surrounded by laws that govern everything – determining the colour of the stars, the gravity controlling our solar system and the beginning and end of the universe itself.

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 up at asteroids and see payday, not doomsday. Some asteroids are loaded with ele¬ments that could be worth billions of dollars: 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. Will asteroids turn out to be our economic salvation–or instruments of extinction?
