Here’s How to Deflect a Dangerous Asteroid Without It Totally Backfiring

The orbital shove demonstrated an asteroid deflection technique that could come in handy if a massive rock were headed in Earth’s direction. As it turns out, however, deflecting a potentially threatening asteroid is only half the battle. Striking an asteroid for deflection purposes could send it back on a collision course with Earth, merely delaying the planet-shatterin
