Deep Impact Mission Info Cache

Space.com has a nifty area devoted to NASA's Deep Impact mission to smash a probe into the comet Tempel-1 and determine its composition. The two parts of the probe, Flyby and Impactor will function as their names imply: Impactor, an 820-pound camera and sensor equipped probe will be left to collide with the comet while the other half, Flyby, will maintain a safe distance and capture the whole thing on video. It should be interesting. Even if nothing happens, that will be interesting.
More likely though, there will be fireworks of some sort. Personally, I think comets could be veritable petri dishes of microbial life, perhaps suspended in ice until crashing into something else, and finding a safe place to grow again. There's definitely ice and rocks at the core; something to come in contact with Impactor other than gas.
Different comets could be made of different stuff. But in little more than a month we will get our answer as to exactly what's at the center of this particular comet. And scientists will get enough data to keep them happy for a while. At least until they get to safely smash a Spaceship into something else.
