Space superiority is the next front in future wars between industrialized nations. It may seem useless to us now, but sooner or later whether its 5 years or in 500 years space will be as important as ground, air and sea dominance. The United States should do every thing it can to further their dominance in this area. In addition, space exploration leads to product innovation, which leads to lots of money in new technology and ways of doing things. If we stop pursuing space technologies, then someone else, like china will discover them and reap the benefits.
