Here's a neat story, about a near-future space collision--a man-made one!

Deep Impact — as the spacecraft is called — will travel six months to reach a comet, named Comet Temple 1. It will then release an 825-pound impactor to search out and collide with the 5-mile long, 2-mile wide comet.

It's amazing what people can do, when they put their minds to it.
