NASA's deep impact

[LightningGSX]

NASA calls it "An experiment in planetary protection". Other than pics, deep impact will also measure the composition of the comet.The pictures will tell us alot in this case, crater size, plume, etc.It will at least give us SOME data on the possibility of diverting/destroying a comet on a collision course with us.Because somewhere, THERE IS a comet that is on a collision course with earth, and there's no doubt about it.

On a side note, I'm suprised there weren't more conspiracy theories about this one.
