The idea of exploiting the natural resources on asteroids has been around for more than a century. But a new company called Planetary Resources has the financial backing of some big names in high tech, and hopes to launch specially-designed prospecting spacecraft within two years.

Avoiding Armageddon: Diverting Asteroids with Nuclear Explosives
Every couple of years, the earth is hit by a body with energy near that of the Hiroshima bomb. Deposited high in the atmosphere these events causes little or no damage. On longer timescales, impacts occur with the potential to destroy regions, or whole civilizations. Learn about the impact threat, followed by a systematic development of the requirements to divert such an object.

Impact! by Professor Ian Morison
There is simple evidence that, even in recent times, the Earth has suffered major impacts from asteroids and comets. What dangers do they hold for our civilisation?
Major efforts now being made to detect those that might harm us and strategies are being developed to prevent their impacts. But we do have a problem with comets…
