In 1961, when President Kennedy declared that America would send a man to the moon by thedecades end, those words, too, had a dreamlike quality. They resonated (共鸣) with optimism and ambition in much the same way as the most famous dream speech of all, delivered by Martin Luther KingJr. two years later. By the end of the decade, both visions had yielded concrete results and transformedAmerican society. And yet in many ways the two dreams ended up at odds with each other.The fight forracial and economic equality is intensely pragmatic (讲求实用的) and immediate in its impact. The urgeto explore space is just the opposite, It is figuratively and literally otherworldly in its aims.
When the dust settled, the space dreamers lost out. There was no grand follow-up to the Apollomissions. The technologically compromised space shuttle program has jus come to an end, with nosuccessor. The perpetual argument is that funds are tight, that we have more pressing problems here onEarth. Amid the current concerns about the federal deficit, reaching toward the stars seems a dispensableluxury--as if saving one-thousandth of a single years budget would solve our problems.
But human ingenuity struggles on. NASA is developing a series of robotic probes that will get the mostbang from a buck. They will serve as modern Magellans, mapping out the solar system for whateverexplorers follow, whether man or machine. On the flip side, companies like Virgin Galactic are plotting abottom-up assault on the space dream by making it a reality to the public. Private spaceflight could liewithin reach of rich civilians in a few years. Another decade or two and it could go mainstream.
