There is something about spaceflight that captivates us as human beings. The fact that we have been bound to this blue rock being hurled around a star for thousands of years seems like a non-issue, especially when we take to the stars, be it on a robotic or human mission. We see something amazing happen. Something that originated from this Earth is no longer bound to it. When one sees a human-made ship leave Earth, we are amazed at not only the power and the sound and the sight, but that we as a species have come so far as to visit other worlds.
