For more than 2,000 years, rockets have been evolving from toys to weapons to complex machines capable of exploration. Rockets and rocket power remain the only means of travel to and through space. Their developement hinged upon discovery, necessity, and experimentation. This development and evolution of rockets did not move in a straight line. Ideas and experiments founded only in fantasy and not in science and mathematics often failed, but rocketeers gradually learned. Some of our major contributors influencing them on were dreamers and poineers like Jules Verne, Konstantin Tsiolkovsky, Robert Goddard, Wernher von Braun, and Homer Hickam. In the words JFK, "not because they are easy, but because they are hard". Innovation and major leaps in science have been paved by these early pioneers and their rockets.
