Power Hungry in Space
摘要
Any serious effort to become a spacefaring civilizationCivilization will require powerPower. PowerPower is fundamental to many of the critical elements of space travel, space exploration, and ultimately to the building of a human presence on other worlds. Think about powerPower and you may immediately come up with electrical systems like computers and radios that are needed to plot a course, control thrusterThrust firings, and communicate with ground stations. These are certainly good examples of what drives powerPower needs today on the relatively small spacecraft that we have sent out to explore and characterize our solar system. However, as we begin to contemplate human voyages deeper into space, the need for powerPower extends to systems such as environmental control, lifeLife supportLife support, and medical care. When we reach the surface of other worlds, there will be resourcesResources that can be used to sustain the human presence. The mining and extraction of fundamental elements such as oxygen require even greater amounts of powerPower. Exploration will require surface mobility, and these vehicles will also increase powerPower demands. The general statement can be made: Without powerPower, there can be no attempt to become a spacefaring civilizationCivilization.
