the case for colonizing mars

But provided one can survive the regimen, it is the toughest schools that are the best. Mars is the best case scenario to our worst case scenario.

That’s just the beginning, because it will eventually be possible for humans to substantially thicken Mars’ atmosphere by forcing the regolith to outgas its contents through a deliberate program of artificially induced global warming. But the biggest problem with the Moon, as with all other airless planetary bodies and proposed artificial free-space colonies, is that sunlight is not available in a form useful for growing crops. The primary analogy I wish to draw is that Mars is to the new age of exploration as North America was to the last. The Earth’s Moon, close to the metropolitan planet but impoverished in resources, compares to Greenland. Such domes up to 50 meters in diameter are light enough to be transported from Earth initially, and later on they can be manufactured on Mars out of indigenous materials. And significantly for interplanetary commerce, Mars and Earth are the only two locations in the solar system where humans will be able to grow crops for export. Mars is a bleak, cold, airless, rust-stained world. Carbon, nitrogen, and hydrogen are only present on the Moon in parts per million quantities, much like gold in seawater. These goods can be fairly limited in mass, as only small portions (by weight) of even very high-tech goods are actually complex. But if you wish to manufacture solar panels, so as to create a self-expanding power base, Mars holds an enormous advantage, as only Mars possesses the large supplies of carbon and hydrogen needed to produce the pure silicon required for producing photovoltaic panels and other electronics. These inventions, licensed on Earth, could finance Mars even as they revolutionize and advance terrestrial living standards as forcefully as nineteenth century American invention changed Europe and ultimately the rest of the world as well. These goods can be fairly limited in m… That’s just the beginning, because it will eventually be possible for humans to substantially thicken Mars’ atmosphere by forcing the regolith to outgas its contents through a deliberate program of artificially induced global warming. Earth normal pressure, temperature and gravity plus an active ionosphere and thick atmosphere to shield you from ionizing radiation … and Earth-normal air is as buoyant at Venus+50 as Helium is on Earth. And significantly for interplanetary commerce, Mars and Earth are the only two locations in the solar system where humans will be able to grow crops for export. Would this provide humanity with a back-up planet in case something terrible happens on earth? Now he makes the case that living on Mars is not just plausible, but inevitable. Will we find it? Would colonizing Mars serve the greater good? If we really want Martian colonies, we can’t send just a few Adams and Eves. "The Case for Colonizing Mars." Once fusion reactors go into widespread use deuterium prices will increase. This website is an initiative of Network for Church Monitoring, a non-profit-making company limited by guarantee (No. The point to be made is that unlike colonists on any known extraterrestrial body, Martian colonists will be able to live on the surface, not in tunnels, and move about freely and grow crops in the light of day. Thus, for decades and perhaps longer, it will be necessary, and forever desirable, for Mars to be able to import specialized manufactured goods from Earth. Growing crops with electrically generated light is just economically hopeless. Even if you did that, it wouldn’t do you any good on the Moon, because plants won’t grow in a light/dark cycle lasting 28 days. Once that has been accomplished, the habitation domes could be virtually any size, as they would not have to sustain a pressure differential between their interior and exterior. On Mars, in contrast, the strong greenhouse effect created by such domes would be precisely what is necessary to produce a temperate climate inside. This post by Dr. Robert Zubrin originally appeared at National Space Society. Miners operating among the asteroids will be unable to produce their necessary supplies locally. To create a vibrant civilization you need a richer power base, and this Mars has both in the short and medium term in the form of its geothermal power resources, which offer potential for large numbers of locally created electricity generating stations in the 10 MW (10,000 kilowatt) class. But despite the shortsighted calculations of eighteenth-century European statesmen and financiers, the true value of America never was as a logistical support base for West Indies sugar and spice trade, inland fur trade, or as a potential market for manufactured goods. He is also a best-selling author, with eight books to his credit. In contrast, the Moon has had virtually no history of water or volcanic action, with the result that it is basically composed of trash rocks with very little differentiation into ores that represent useful concentrations of anything interesting. The foundational piece of space legislation is the Outer Space Treaty, which was ratified by the U.S., U.S.S.R., and dozens of other nations in 1967.Per the treaty, nations aren’t allowed to place “nuclear weapons” or “weapons of mass destruction” in outer space, period. But if you wish to manufacture solar panels, so as to create a self-expanding power base, Mars holds an enormous advantage, as only Mars possesses the large supplies of carbon and hydrogen needed to produce the pure silicon required for producing photovoltaic panels and other electronics.
