Republican presidential candidate Newt Gingrich, in apparent desperation, resorted to the JFK playbook when he said that by the end of his second putative term as President, the United States would have a permanent base on the Moon. I laud the sentiment, even though Gingrich provided no details about how such a venture would be funded. This is of particular importance here because a central element of the old House Speaker’s “Contract with America” was to cut government spending, not to expand it, a policy platform that has by now become so rote that it is always spoken, but rarely upheld, by politicians of the Republican brand.
Still, as a society, as a culture, as a nation and, most palpably, as a species, we need to do precisely what Gingrich proposed. The late popular astronomer Carl Sagan argued that a return to the Moon would be an unwise expenditure of resources. His opposition was based on his well-informed opinion that the Moon offered little of practical value. Instead, Sagan argued, the benefits of space science could be derived from orbital stations which would also serve as platforms where space vessels could be built in zero gee and from which eventual robotic and manned missions to Mars, the moons of Jupiter and Saturn, and to the asteroid field could be launched. These worlds, Dr. Sagan argued, contain more clues to the origins of our solar system and the nature of the universe, and more opportunities for discovery, of extraterrestrial life or other wonders, than does Earth’s closest companion. But Dr. Sagan died before we learned that there are great quantities of water on the Moon, in the form of ice that can be formulated to fuel spacecraft. A permanent base on the Moon might yet make sense, not for Gingrich’s stated nationalistic purposes (space travel should unite our species, not further divide us), but as a nearby low gee location for spaceship construction and as a logical place to begin what will forever be the necessary human undertaking of extraterrestrial colonization.
Looked at in this light, cost becomes irrelevant. As a nation, the United States invested enormous human and financial capital in the 1960s to win the space race with the Soviet Union, to fight a futile war in Southeast Asia, and to transform the cultural landscape of America’s domestic front. Do not decisive steps toward the assurance of the survival of our very species deserve such investment as well? Dr. Neil deGrasse Tyson, astrophysicist and director of New York’s Hayden Planetarium, thinks so. In addition to the impact that a healthy focus on what he calls “the ultimate frontier” would have on the American imagination, Dr. Tyson adds that the human race is in desperate need of an infusion of wonder, of an audacious vision, of a grand mission forward into a glorious future that would stimulate invention by promoting great new strides in education, industry, engineering, the sciences and high technology. To literally reach for the stars, especially during dubious times of economic uncertainty, political upheaval and ecological revolt, can reignite the spark of human imagination and motivate us to work together like no other endeavor. The dream of being able to live and thrive on another world can move us to create the means to make that dream a reality.
The human race must pursue this dream. As the sheer numbers of humans expand beyond this planet’s sustainability threshold, we will eventually have no choice but to spread to other worlds. Perhaps a more crucial consideration is the fact that Earth will not remain forever habitable, that a cataclysmic event resulting in our extinction is possible even in the not-too-distant future. Our species, uniquely so in the universe as far as we know, has risen to a point at which it can imagine leaving the planet of its birth, colonizing other worlds, and voyaging among the stars. It would be a disappointment of cosmic proportions if that dream were to be left unrealized when it rests so tantalizingly close to our grasp.
To the Moon, then, and beyond!
