This is an extremely important point and it is not well understood. R. Zubrin and C. McKay, "Technological Requirements for Terraforming Mars," AIAA 93-2005, AIAA/SAE 29th Joint Propulsion Conference, Monterey CA 1993. Networks of such 50 to 100 meter domes could rapidly be manufactured and deployed, opening up large areas of the surface to both shirtsleeve human habitation and agriculture. But as soon as people commit to living there for their entire lives, they’re going to want to give the place an atmosphere to protect themselves from radiation. Science fiction writer Kim Stanley Robinson is one. The purpose of the exploration phase is to resolve the major outstanding scientific questions bearing on the history of Mars as a planet and a possible home for life in the past, to conduct a preliminary survey of the resources of Mars and determine optimum locations for future human bases and settlements, and to establish a modus operandi whereby humans can travel to, reside on, and conduct useful operations over substantial regions of the surface of Mars. Space, a feel-good pill for the economy Of course, all open real-estate on Mars will not be of equal value; those sections known to contain valuable minerals or other resources, or which are located closer to the habitable areas will be worth much more. Put simply, if enough people find a way to live and prosper on Mars there is no doubt but that sooner or later they will terraform the planet. J. Lewis and R. Lewis, "Resources from Space: Breaking the Bonds of Earth". Rather, they shall be based on the concrete case of Mars itself, its unique characteristics, resources, technological requirements, and its relationships to the other important bodies within our solar system. It’s actually very hard to land softly on Mars, and we only have about a 50 percent success rate with our robots. Moreover, on Mars, as on Earth, hydrologic and volcanic processes have occurred, which is likely to have concentrated various elements into local concentrations of high-grade mineral ore. A comparison of Earth to Ceres and Mars to Ceres all chemical and chemical/NEP missions is shown in Table 2. On Mars, even during the base building phase, large inflatable greenhouses made of transparent plastic protected by thin hard-plastic ultra-violet and abrasion resistant geodesic domes could be readily deployed, rapidly creating large domains for crop growth. What do you think are the dangers of that? Your investment in Marketplace helps us remain paywall-free and ensures everyone has access to trustworthy, unbiased news and information, regardless of their ability to pay. If the launch vehicle used has a 1000 tonne liftoff mass, if would require 107 launches to assemble the CH4/O2 freighter mission if launched from Earth, but only 2 launches if the departure is from Mars. The feasibility or lack thereof of terraforming Mars is thus in a sense a corollary to the economic viability of the Martian colonization effort. As America showed in the 19th Century, such an engine of can pull far more than its own weight. Fig. In 1802, Napoleon Bonaparte sold a third of what is now the United States for 2 million dollars. The Benefits of Colonizing Space: Space Habitats and The O’Neill Cylinder ... Mars One graphics. Dinkin, S. (2018). As mentioned before, the labor shortage that will prevail on Mars will drive Martian civilization towards both technological and social advances. Examining the graph, we see that with this level of effort (and the technology frozen at late 20th Century levels forever), the rate of human population growth of Mars in the 21st Century would be about 1/5th that experienced by colonial America in the 17th and 18th Centuries. The point, however, is that in contrast to colonists on any other 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. For a long time it might be considered to be an exotic place where we don’t need to change it. If we assume that there is operating between Earth and Mars a cycling spacecraft which has the ability to recycle water and oxygen with 95% efficiency, then each passenger (100 kg with personal effects) will have to bring about 400 kg of supplies to provide himself with food, water and oxygen during a 200 day outbound trip to Mars. Moreover the projected population growth rate, 1/5th that of Colonial America, while a bit slow, is significant on a historical scale, and assuming a cost of $1 billion per launch, the $4 billion per year program cost could be sustained for some time by any major power on Earth that cared to plant the seeds of its posterity on Mars. Mars is not habitable for humans and most will die before some very expensive infrastructure is erected, if one ever gets built. It is obvious that habitable real-estate is far more valuable than open real-estate. This contrasts strongly with the Moon, which is so dry that if concrete were found there, Lunar colonists would mine it to get the water out. Mars and Earth have very similar lengths of days. During the period of their global ascendancy, the Spanish ignored North America; to them it was nothing but a vast amount of worthless wilderness. What can Mars possibly export back to Earth in return? Let us therefore examine an alternative model to see how low it is likely to drop. Use of reflectors and other light-channeling devices would not solve this problem, as the reflector areas would have to be enormous, essentially equal in area to the crop domains, creating preposterous engineering problems if any significant acreage is to be illuminated. Improving the quality of life on Earth. Space colonization is a controversial topic for some people, though definitely not for me, and for a number of … Colonizing Mars will provide a contingency plan for humanity. If a viable Martian civilization can be established, its population and powers to change its planet will continue to grow. Let us consider two models of how humans might emigrate to Mars; a government sponsored model and a privately sponsored model. In analogy to frontier America, social conditions on Mars will make it a pressure cooker for invention. A planet of refuge will be needed, and Mars will be there. R. Zubrin, "Mars and Luna Direct," Journal of Practical Applications in Space, Vol 4, No. It’s crazy and nobody likes it. Increasing the degree of closure of the life support system on the cycler would reduce the consumable delivery requirement for each passenger, thereby reducing passage costs still more. People create wealth, people create power. Under conditions of such large scale and open immigration, sale of real-estate will add a significant source of income to the planet's economy. Current knowledge indicates that if Mars were smooth and all it's ice and permafrost melted into liquid water, the entire planet would be covered with an ocean over 100 meters deep. I define four phases, which I term "exploration," "base building," "settlement," and "terraforming.". This sort of mechanism would not imply US sovereignty over Mars, any more that the current US Patent and Copyright Offices coining of ideas into intellectual property implies US government sovereignty over the universe of ideas. I don’t need to be thanked. Thus for each passenger a total of 1000 kg needs to be delivered to the cycler orbit, which with an Isp of 380 s for the CH4/O2 propulsion system on the transfer capsules translates into 3200 kg in LEO. Oxygen is abundant on the Moon, but only in tightly bound oxides such as SiO2, Fe2O3, MgO, and Al2O3, which require very high energy processes to reduce. Production of halocarbons at this rate would require an industrial establishment on Mars wielding about 5000 MW or power supported by a division of labor requiring at least (assuming optimistic application of robotics) 10,000 people. This in itself is a very significant result. It can also be seen that there is a five-fold advantage in mass ratio delivering cargoes to the Earth's Moon from Mars over doing it from Earth. Once that is in place, however, even the undeveloped open real-estate on Mars represents a tremendous source of capital to finance the initial development of Martian settlements. D. Baker and R. Zubrin, "Mars Direct: Combining Near-Term Technologies to Achieve a Two-Launch Manned Mars Mission," JBIS, Vol. In Table 1 all the entries except the last two are based upon a transportation system using CH4/O2 engines with an Isp of 380 s and high thrust DV's. 3. Necessity is the mother of invention; Mars will provide the cradle. Robert Zubrin On Tuesday, tech entrepreneur Elon Musk told the world he has a plan to help humanity establish a colony on the planet Mars. This process of rejuvenation, and not direct economic benefits via triangle-trade for main-belt asteroid mineral resources, will ultimately be the greatest benefit that the colonization of Mars will offer Earth, and it will be those terrestrial societies who have the closest social, cultural, linguistic, and economic links with the Martians who will benefit the most. It has been shown9 that if concentrated supplies of metals of equal or greater value than silver (i.e. Today, the same method of obtaining passage is used by Third World immigrants whose salaries in their native lands are dwarfed by current air-fares. This uniqueness is illustrated most clearly if we contrast Mars with the Earth's Moon, the most frequently cited alternative location for extraterrestrial human colonization. Since such systems are well outside current engineering knowledge it is difficult to provide any useful estimate of how quickly they could complete the terraforming job. The asteroid belt enters into the picture here because it is known to contain vast supplies of very high grade metal ore10 in a low gravity environment that makes it comparatively easy to export to Earth. 43 No. ... And that spells political and economic benefit for whoever succeeds. 11, Nov. 1990 pp. The Earth's Moon, close to the metropolitan planet but impoverished in resources compares to Greenland. The costs impacts as each of these innovations is progressively introduced is displayed in Table 3. All logistics … I know I would! The existence of such Martians precious metal ores, however, is still hypothetical. Assuming that dwelling units for 20 families are erected within it, and each family is willing to pay $50,000 for their habitation land (a plot 20 meters on a side), then the total real-estate value enclosed by a single dome would be $1,000,000. How one small business owner kept all his employees with revenue down 70%, Logistical challenges just beginning for nation’s vaccination drive, NASA is testing supercomputers to send to Mars, Reaching Mars is a hard sell, but not impossible, Ten years later, what we learned from WALL-E, Imagining the everyday economy of the moon, In the novel ‘Delta-v,’ asteroid mining gets us to move to space, Climate adaptation isn’t surrender. 2 we see one version of such a concept that could be used to transport immigrants to Mars. If we then make various reasonable demographic assumptions, the population curve for Mars can be computed. were available on Mars, they could potentially be transported back to Earth at high profit by using reusable Mars-surface based single stage to orbit vehicles to deliver the cargoes to Mars orbit, and then transporting them back to Earth using either cheap expendable chemical stages manufactured on Mars or reusable cycling solar sail powered interplanetary spacecraft. Their motives for doing so will parallel in many ways the historical motives for Europeans and others to come to America, including higher pay rates in a labor-short economy, escape from tradition and oppression, as well as freedom to exercise their drive to create in an untamed and undefined world. While humans could not breath the atmosphere of such a Mars, plants could, and under such conditions increasingly complex types of pioneering vegetation could be disseminated to create soil, oxygen, and ultimately the foundation for a thriving ecosphere on Mars. So it will be scientific crews and people who keep the infrastructure going. William Bradford, "Of Plimoth Plantation," 1621. Only Mars has the full set of resources required to develop a native civilization, only Mars is a viable target for true colonization. Enormous tracts of land were bought and sold in Kentucky for very large sums of money a hundred years before settlers arrived - for purposes of development trans-Appalacian America might as well have been Mars in the 1600's. As we get closer to life on Mars, we have to start thinking about what its economy would look like and how that might affect the rest of us here on Earth. All Rights Reserved. Furthermore, such claims would be enforceable internationally and throughout the solar system simply by having the US Customs Office penalize with a punitive tariff any US import made anywhere, directly or indirectly, with material that was extracted in defiance to the claim. However in the case of self-replicating machines the ultimate source of power would be solar, and this provides the basis for an upper bound to system performance. Even if Mars is a lifeless planet, whether it’s ethical to colonize Mars may depend on what kinds of consequences the mission has here on Earth. Potential increases in real-estate values after terraforming will provide a sufficient financial incentive to do so. If we then assume total system operation cost is 7 times propellant costs (roughly double the total cost/fuel cost ratio of airlines), then the cost of delivery to low Earth orbit (LEO) could be about $100/kilogram. And while there were a lot of exciting technical details, some major issues I anticipated were not covered. 9. Simply this, because of the small size of the Martian population and the large transport cost itself, it is certain that the cost of labor on Mars will be much greater than on Earth. Colonization of Mars compared to North America. These arguments appear to be ironclad, yet it must be pointed out that they were also presented in the past as convincing reasons for the utter impracticality of the European settlement of North America and Australia. These goods can be fairly limited in mass, as only small portions (by weight) of even very high-tech goods are actually complex. As a nonprofit news organization, our future depends on listeners like you who believe in the power of public service journalism. For example use of air-breathing supersonic ramjet propulsion to perform a significant part of the Earth to orbit DV could cut orbit delivery costs by as much as a factor of 3. 11. The first benefit is one of the main reasons why Elon Musk believes that we should colonize Mars: it would mark the beginning of extraterrestrial life for human beings. In 1867 the Czar sold off Alaska for a similar pittance. This would be the most monumental achievement in our history to date and would likely be a point in history we would never forget. In fact, if a mechanism were put in place that could enforce private property rights on Mars, land on Mars could probably be bought and sold now. If Mars is ever to benefit from the dynamic energy of large numbers of immigrants motivated by personal choice to seek to make their mark in a new world, the transportation fee will have to drop a lot lower than this. Once the techniques have been mastered that will allow the support of a large population on Mars out of indigenous resources, the settlement of Mars can begin. A similar triangle trade involving Britain, Australia, and the Spice Islands also supported British trade in the East Indies during the 19th Century.
