On January 13, scientists spotted a large asteroid seemingly on a collision course with Earth. It was a miscalculation, luckily, because aerospace engineer John Olds says Hollywood's solutions won't work. For example, even if we could nuke an asteroid, it would simply turn a huge cannon ball into a huge shotgun blast. Olds' company, SpaceWorks Engineering, is developing a unique plan for the NASA Institute of Advanced Concepts. Thousands of small spacecraft would orbit near the moon. If a dangerous asteroid is confirmed, they'd be ordered to swarm onto it, then rapidly dig and chuck golfball-sized pieces of the asteroid into space. Like throwing rocks from a boat in still water, Olds says—given enough lead time—the effect could nudge an asteroid's path enough to avoid us. One idea for taking the bite out of dangers from space.
