I would absolutely love to stand on the surface of Mars or see Alpha Centauri with my own eyes, but I also know that such things are outside of my grasp. Poets and philosophers make for lousy explorers. It is enough for me that we, as a species, are reaching upward. It is enough for me that we, as a people, are overcoming chains that were not even imagined by our ancestors -- tasks so difficult, so alien that they would only describe it as touching the face of god. This is about more than the whimsical realized dream of an individual; it is the progression of the entire species. This is how human beings are made great.
