Nukes best for saving Earth from asteroids
01 July 2010
Scientists argue that the best way to prevent a large asteroid from doing grave damage to Earth is to blast the asteroid with nuclear weapons; the sheer power of a nuclear explosion may make it the most practical and cost-effective option for deflecting or fragmenting asteroids, compared with alternatives such as chemical fuel or laser beams
For one thing, a nuclear explosive would be cheaper to launch into space due to its large amount of energy per unit mass; in contrast, a non-nuclear blast might require several launches for an equivalent amount of power.
