But human ingenuity struggles on. NASA is developing a series of robotic probes that will get the most bang from a buck. They will serve as modem Magellans, mapping out the solar system for whatever explorers follow, whether man or machine. On the flip side, companies like Virgin Galactic are plotting a bottom-up assault on the space dream by making it a reality to the public. Private spaceflight could lie within reach of rich civilians in a few years. Another decade or two and it could go mainstream.

　　The space dreamers end up benefiting all of us not just because of the way they expand human knowledge, or because of the spin-off technologies they produce, but because the two types of dreams feed off each other. Both Martin Luther King and John Kennedy appealed to the idea that humans can transcend what were once considered inherent limitations. Today we face seeming challenges in energy, the environment, health care. Tomorrow we will transcend these as well, and the dreamers will deserve a lot of the credit. The more evidence we collect that our species is capable of greatness, the more we will actually achieve it.
