NASA's Deep Impact probe successfully collided with a comet, in a move the NASA scientists describe as the equivalent of "hitting a bullet with another bullet while positioning a third bullet to be in place to watch the impact".  Sadly, this monumental bit of engineering and calculation got only passing mention in the media compared to a local scandal involving a man accused with soliciting a 14-year-old for sex...

Congratulations on a job well done, NASA!  Best of luck with the Rosetta spacecraft (due to do the same thing in the year 2014).
