Congratulations to NASA for taking one more step on the road from science fiction to science fact. Granted hitting a comet with a washing machine sized chunk of copper is easier than landing a man on one, but still its one more step towards Bruce Willis saving the world.
Unfortunately for NASA it appears not everyone is happy. A Russian astrologer has sued them for "moral suffering" caused by the "deforming of her horoscope". Maybe she would have more success claiming she got whiplash in the crash?
