Deadly Space Rocks Likely Unstoppable

They scoff at Bruce Willis

Space is out to kill you. There is no way to stem its aggression. But it's usually an incompetent killer, so don't freak out.

The last thing residents of Chelyabinsk, in central Russia, expected on Friday was to see a flaming fireball from the heavens hurtle towards their industrial city. On-scene accounts make it seem like an angry deity enacted His vengeance for some unknown slight. The meteor was actually unrelated to the 2012 DA14 asteroid near Earth, according to NASA. (Which, by the way, you can watch soar by.) But 1,000 Russians were injured from the concussive blast and flying, shattered glass.

All the advanced air defenses that humanity has invested in? The interceptor missile that are (sometimes) able to stop an adversary missile from impacting? The early-warning monitoring systems that are supposed to give humanity enough time to plan a response? They are useless, useless against a meteorite onslaught. Do not believe the stories about the Russians shooting the cosmic rock down.
