The Meaning of Space Settlement by Douglas O. Jobes Try discussing with the average American the concept of settling space, and you may get some strange reactions. To many, the phrase "space settlement" (sometimes referred to as "space colonization") evokes images of the Old West, where lone adventurers and families in wagontrains headed into the wilderness looking for a better life. To others, the plight of the American Indians, displaced from their lands by waves of settlers, comes to mind. Those with an interest in world history may recall other efforts at settling new territory, from colonization around the Mediterranean by the ancient Greeks, to settlement in Australia by Europeans in modern times. And of course, fans of science fiction authors like Isaac Asimov, Robert Heinlein, Ben Bova, and others may envision cities on the Moon, Mars, or elsewhere in the solar system, habitations in orbit around the Earth, or even permanent bases on the planets of nearby stars. If your listener hasn't given it much thought, as most people have not, the space settlement concept will probably seem like a fringe or "far-out" idea. Long-running shows such as Star Trek and its derivaties, movies like the Star Wars series, and of course the multitude of science fiction novels published since the early years of the 20th century have helped unlock our imaginations to what the future could hold, but this has been a double-edged sword as well. The mixture of fantasy and invention in the portrayal of humanity's destiny in space creates a sense of unreality. Of course, when predicting the future, anything is "unreal" in the sense it hasn't yet happened. In the case of colonies in space, though, sometimes the predictions have not only been laced with liberal doses of fantasy, but often the manner they are portrayed gives the impression the events are situated in the extremely distant future ("in a galaxy far, far away"), and not necessarily something within our reach right now. With a mental image of either the old American West and the European settlement efforts of the 19th century or of the far-flung science fiction/fantasy of the Star Wars movies, it is no wonder many people don't consider space settlement a serious topic for discussion. It doesn't seem to have importance to their own lives, since the colonization on Earth that they've heard about stopped long ago, and the colonization in space they've seen or read about is somewhere in the distant, imagined future. In reality, however, the gap between science fiction and science fact is closing quickly. The past may be out of reach, but the so-called "distant future" is not necessarily as remote as most people assume. So what would a real space settlement look like? It need not consist of a huge fleet of forever-roaming interstellar colony ships as depicted in the 1970's show Battlestar Galactica. A space settlement doesn't mean a distant planet where every square inch of land is covered with man-made structures, like the administrative planet Trantor in Asimov's Foundation novels. A space settlement might simply be a small city on the Moon, for example. The city could be built to support the activity of a bustling Lunar base. Such a base could be founded by NASA pursuant to the Moon-to-Mars initiative, or founded by private entrepreneurs hoping to make their fortunes through Lunar real estate speculation, Lunar hotels and tourism, production of solar energy, or other means. The concept of settling space is not that complicated or "far out." And while there are echos in space settlement of the European colonization efforts of the 1800's and earlier, the essentials are obviously quite different - including the important point that space is uninhabited. There are no indigenous peoples in space who stand to lose their land, cities, hunting grounds, or their lives when we establish a permanent presence there. It may be true that the days of settlers establishing new colonies here on Earth are long gone, but the first chapter of the settling of space is being written as we speak. The President's Moon-to-Mars intiative announced in January 2004 set NASA on the road to establishing permanent bases on the Moon and then on Mars over the course of the next few decades. Hopefully NASA will succeed, though the agency faces very serious obstacles, not the least of which is surviving the policy changes and budgetary axes of so many Presidential administrations. In the end, it may be the initiative and innovation of private industry - as demonstrated vividly by the X-Prize competition - that link our time to a new space settlement era. We live during a special time in history - a hiatus between thousands of years of human expansion on Earth and the potential of a new and greater age of expansion into the next great frontier. The settling of space is an obvious, and quite natural, next step for humankind. But it is up to us to make it happen. | |||
