Laser Defense From Asteroids

Asteroid

Could a “Deathstar” someday defend Earth against incoming threats from space? Last Friday, asteroid 2012 DA14 -- half a football field long and weighing about 190,000 tons -- missed plane Earth in a fly-by. Far smaller and therefore harder to detect was the 50 foot long asteroid that injured more than 1,000 Russians when it stuck a few hours earlier.
