The meteor that wreaked havoc in Russia last week, shattering windows around a 50-acre area and injuring 1,200 people, was not as big as the asteroids that Dr. Bong Wie of Iowa State University is worried about. He is researching how to stop one of the 400 asteroids scientists have discovered, which have some chance of crashing into Earth and potentially destroying a city.
Wie has gotten NASA’s attention with a plan that seems right out of the Hollywood blockbuster "Armageddon." He is working on a plan to bury a nuclear bomb into a potentially deadly asteroid and blow it up into tiny pieces.
