re: DEEP IMPACT...Hit or MISS?
Did you post this twice to cover all the bases? :^)
In the event the big copper ball does miss Tempel 1, the good news is that the mission is neither a complete failure nor over. The flyby half will still image the comet up close and there have already been plans for it to zip past other ancient ice balls.
So while it would certainly be sad if the impactor didn't live up to its name, Deep Impact will carry on.
