By far, the most exciting moment at Cape Canaveral is the launch of a space mission. You hear the man in Mission Control counting down, "3...2...1...Liftoff!" Then there's that huge cloud of smoke at the base of the rocket. Then you can see the blazing fire lifting that rocket and its' precious cargo off the pad and into the sky. It's a very impressive sight. But that's not the end of it. You don't just say, "Great launch. Let's go home." No, no. All that fire and smoke isn't just to have a powerful experience - it's to launch a mission, to make some things happen that would never otherwise happen.
