Mars has every required element in abundance. To understand this, it is necessary to consider the energy relationships between the Earth, Moon, Mars, and the main asteroid belt. It has been shown9 that if concentrated supplies of metals of equal or greater value than silver (i.e. 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. Such an operation would be enormous compared to our current space efforts, but very small compared to the overall human economic effort even at present. 2, pp 197-203, March-April 1991. http://www.magick.net/mars/docs/m_econom.txt, Mars Direct Manned Mars Mission Home Page. 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 are the Benefits of a Mars Colony? It was answered that all great & honourable actions are accompanied with great difficulties, and must be both enterprised and overcome with answerable courages. In the primary scenario, artificial greenhouse gases such as halocarbons are produced on Mars and released into the atmosphere. In 1802, Napoleon Bonaparte sold a third of what is now the United States for 2 million dollars. All logistics … 2. It is this question that has caused many to deem Mars colonization intractable, or at least inferior in prospect to the Moon. 6. We have examined the potential of relatively near-term types of interplanetary transportation systems, and shown that with very modest advances on a historical scale, systems can be put in place that will allow individuals and families to emigrate to Mars at their own discretion. These inventions, licensed on Earth, could finance Mars even as they revolutionize and advance terrestrial living standards as forcefully as 19th Century American invention changed Europe and ultimately the rest of the world as well. Science fiction writer Kim Stanley Robinson is one. At a delivery price of $100/kg to LEO, and assuming that the cost of the cycler itself is amortized over a very large number of missions, this in turn translates into a cost of $320,000 per passenger to Mars. Instead, let us note the benefits that can come from interplanetary colonization, even for those of us who decide to stay on the Earth’s surface. Marketplace Tech host Molly Wood talked with him about what colonizing the red planet might look like and how — or even if — that would be profitable. Tourism will be a huge early driver for the Martian economy, and galactic parks might be one of its greatest boons. It is obvious that habitable real-estate is far more valuable than open real-estate. 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. Every feature of frontier American life that acted to create a practical can-do culture of innovating people will apply to Mars a hundred-fold. 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. O'Neill, "The High Frontier," William Morrow and Co. New York, 1977. These inventions, licensed on Earth, will raise both Terrestrial and Martian living standards and contribute large amounts of income to support the development of the colony. Plants require an enormous amount of energy for their growth, and it can only come from sunlight. Africa is one continent that was largely affected. It is also shown that while Mars may lack any cash material directly exportable to Earth, Mars' orbital elements and other physical parameters gives a unique positional advantage that will allow it to act as a keystone supporting extractive activities in the asteroid belt and elsewhere in the solar system. Is it worthwhile spending precious resources colonizing mars? 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. I believe that it is certain that two hundred years from now, the current apathy of governments towards the value of extraterrestrial bodies, and Mars in particular, will be viewed in a similar light. The feasibility or lack thereof of terraforming Mars is thus in a sense a corollary to the economic viability of the Martian colonization effort. volatile and more extreme. Fig. R. Zubrin and D. Andrews, "Magnetic Sails and Interplanetary Travel," Journal of Spacecraft and Rockets, Vol 28, No. Not so. There will be a "triangle trade," with Earth supplying high technology manufactured goods to Mars, Mars supplying low technology manufactured goods and food staples to the asteroid belt and possibly the Moon as well, and the asteroids and Moon sending metals and possibly helium-3 to Earth. Inventions produced as a matter of necessity by a practical intellectual culture stressed by frontier conditions can make Mars rich, but invention is not the only way that Martians will be able to make a fortune. Both missions deliver 50 tonnes of cargo. 9. Robert Zubrin We should focus on … 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. Kim Stanley Robinson: The first colonists on Mars I now think will be modeled kind of on Antarctica. By habitable real-estate I mean that which is under a dome, allowing human settlers to live there in a relatively conventional shirt-sleeve open-air environment. The last two entries in the table are based upon nuclear electric propulsion (NEP) using argon propellant, available at either the Earth or Mars, with an Isp of 5000 s for in-space propulsion, with CH4/O2 used to reach low orbit (LO) from the planet's surface. "Only by pushing mankind to its limits, to the bottoms of the … Expand. As human beings, the only home we have ever known is planet Earth. 1, Fall 1992, pp 25-80, 3. Thus plants grown in a thin walled greenhouse on the surface of the Moon or an asteroid would be killed by solar flares. Open real-estate is that which is outside the domes. Ensuring the survival of our species. We have examined the prospects for colonizing Mars, addressing the question of its economic viability. R. Zubrin and D. Weaver, "Practical Methods for Near-Term Piloted Mars Missions," AIAA 93-2089 AIAA/SAE 29th Joint Propulsion Conference, Monterey CA 1993, JBIS, June 1995, 4. Such a price might be affordable to governments (for a time), but not to individuals or private groups. 519-526, 2. The Moon is also deficient in about half the metals (for example copper) of interest to industrial society, as well as many other elements of interest such as sulfur and phosphorus. If Mars should be terraformed, these open land prices could be expected to grow 100-fold, with a rough planetary land value of $36 trillion implied. Robert Zubrin, founder and President of the Mars Society, has come forward with his suggestions to aid economic recovery… President John F. Kennedy at Rice University in 1962. And also since I wrote my Mars books, we’ve discovered that the surface is way more poisonous than we thought it was. First, likening a colony on Mars to life insurance is misleading. B. Cordell, "A Preliminary Assessment of Martian Natural Resource Potential," AAS 84-185, presented to the Case for Mars II conference, Boulder, CO, July 1984. Y esterday a lot of people watched Elon Musk revealing some of his plans on colonization of Mars at the International Astronautical Congress. This triangle trade, illustrated in Fig. Mars, on the other hand, has an atmosphere of sufficient density to protect crops grown on the surface against solar flares. The temperature rise induced by the presence of these gases causes CO2 adsorbed in the regolith to be outgassed, increasing the greenhouse effect still more, causing more outgassing, etc. © 2021 Minnesota Public Radio. As mentioned before, the labor shortage that will prevail on Mars will drive Martian civilization towards both technological and social advances. Ocean colonies are safer. 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. Stanley Robinson: Oh, I think the dangers are of trivialization, that suddenly other planets in space, instead of being a commons that all humans are interested in equally as a scientific project to humanity, it just turns into another source of profit and exploitation. The other way is trade. Consider once again out CH4/O2 SSTO vehicles used to transport payloads from the surface of the Earth to low Earth orbit. The cost of colonizing Mars would far outweigh any economic benefit, unless the planet was solid gold. 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. Donate today — in any amount — to become a Marketplace Investor. Take exploration from a scientific commercial exercise. but despite the short sighted calculations of 18th 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. These goods can be fairly limited in mass, as only small portions (by weight) of even very high-tech goods are actually complex. For these reasons, as with land speculators on Earth in the past, the owners of open unexplored real-estate on Mars will exercise all their influence to further the exploration of, and encourage the settlement of land under their control. In reference 6 it was shown that a rate of halocarbon production of about 1000 tonnes per hour would directly induce a temperature rise of about 10 K on Mars, and that the outgassing of CO2 caused by this direct forcing would likely raise the average temperature on Mars by 40 to 50 K, resulting in a Mars with a surface pressure over 200 mbar and seasonal incidence of liquid water in the warmest parts of the planet. In Global Challenges, Igor Levchenko from Nanyang Technological University and Kateryna Bazaka from Queensland University of Technology, along with their colleagues, discuss the ethical, legal, and economic challenges and open questions facing Mars colonization, drawing attention to the lack of consensus and rich diversity of opinions on the topic. In the early years of settlement, such domes could be imported pre-fabricated from Earth. There is an immense amount of it - 143 million square kilometers - but it might seem that that it is all completely worthless because it cannot currently be exploited. For every kilogram of payload delivered to orbit, about 70 kilograms of propellant are required. 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. Assuming complete coverage of the planet with photosynthetic plants, it would take about a millennia to put the 120 mbar of oxygen in Mars' atmosphere needed to support human respiration in the open. 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. 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. And while there were a lot of exciting technical details, some major issues I anticipated were not covered. In the 21st Century, Earth's population growth will make real-estate here ever more expensive, making it ever harder for people to own their own homes. 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. The real wild card for long-term health is the low gravity. How much unemployment is there? This would be the most monumental achievement in our history to date and would likely be a point in history we would never forget. The Earth's Moon, close to the metropolitan planet but impoverished in resources compares to Greenland. Rather the key questions become those of resource utilization, growing food, building housing, and manufacturing all sorts of useful goods on the surface of Mars. That said, the problem with using the natural sunlight available on the Moon or in space is that it is unshielded by any atmosphere. Analysis assumes 100 immigrants/year starting in 2030, increasing at 2% annual rate, 50/50 male/female. The exploration phase of Mars colonization has been going on for some time now with the telescopic and robotic surveys that have been and continue to be made. 1 The triangle trade: 18th Century and 21st Century. Another alternative is that Mars could pay for itself by transporting back ideas. William Bradford, "Of Plimoth Plantation," 1621. R. Zubrin and David Baker, "Mars Direct: Humans to the Red Planet by 1999" IAF-90-672, 41st Congress of the International Astronautical Federation, Dresden, Germany, Oct. 1990. All immigrants are between ages 20 and 40. While properly conducted initial exploration missions will make use of the Martian air to provide fuel and oxygen, in the base building phase this elementary level of local resource utilization will be transcended as the crew of a permanent Mars base learns how to extract native water and grow crops on Mars, to produce ceramics, glasses, metals, plastics, wires, habitats, inflatable structures, solar panels, and all sorts of other useful materials, tools, and structures. The … Just as the labor shortage prevalent in colonial and 19th century America drove the creation of Yankee Ingenuity's flood of inventions, so the conditions of extreme labor shortage combined with a technological culture and the unacceptability of impractical legislative constraints against innovation will tend to drive Martian ingenuity to produce wave after wave of invention in energy production, automation and robotics, biotechnology, and other areas. Mars used to be a warm and wet planet like Earth, when Mars had a much thicker atmosphere than it … It Will Drive Technological Change on Earth. The outline of future interplanetary commerce thus becomes clear. What made it salable were two things: 1) That at least a few people believed that it would be exploitable someday, and 2) That a juridical arrangement existed (in the form of British Crown land patents) which allowed trans-Appalacian land to be privately owned. 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. 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. I reckon that a very high percent of colonists and space tourists would spend loads extra in order to see the largest mountain and canyon in the galaxy. Moreover, it is an unsuitable propellant for a cheap reusable space transportation system, since it costs more than an order of magnitude more than CH4/O2 (thus ruling it out for true cheap surface to orbit systems) and its bulk makes if very difficult to transport to orbit in any quantity using SSTO type vehicles. Denver, CO 80201, USA A comparison of Earth to Ceres and Mars to Ceres all chemical and chemical/NEP missions is shown in Table 2. The Space Review: Colonize the Moon before Mars. Let us consider two models of how humans might emigrate to Mars; a government sponsored model and a privately sponsored model. 43 No. Regulation to "protect" what is will become ever more burdensome to those who would create what is not. 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. That brings us to the first reason why humans must colonize Mars: 1. Molly Wood and Kristin Schwab Oct 24, 2017. There are plenty of creatives who have already been doing lots of brainstorming about this. PO Box 179 Assuming the whole planet is covered with machines converting sunlight to electricity at 30% efficiency, and all this energy is applied to releasing oxygen from metallic oxides, a 120 mbar oxygen atmosphere could be created in about 30 years. no spacesuits) would be required to operate in the open, and city-sized inflatable structures could be erected (since there would be no pressure differential with the outside world) that could house very large settlements in an open-air shirt-sleeve environment. 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. Colonizing Mars will provide a contingency plan for humanity. The existence of such Martians precious metal ores, however, is still hypothetical. We have seen that despite the fact that Mars may lack any resource directly exportable to Earth, Mars' orbital elements and other physical parameters gives a unique positional advantage that will allow it to act as a keystone supporting extractive activities in the asteroid belt and elsewhere in the solar system. (Originally found as badly formatted text at http://www.magick.net/mars/docs/m_econom.txt, a part of Mars Direct Manned Mars Mission Home Page). I am very interested in the current talk about Mars. An artist's conception of the Phoenix Mars lander on the red planet. ... And that spells political and economic benefit for whoever succeeds. Mars is a place where humans can live and multiply to large numbers, supporting themselves with products of every description made out of indigenous materials. Obviously, there are many assumptions in the above calculation that could be changed that would either raise or lower the calculated ticket price significantly. 8.G. Establishing a colony on Mars would benefit our society in a number of ways. The first, and most notable way, is that a colony on Mars would mark the first interplanetary settlement in human history. Like America in its relationship to Britain and the West Indies, Mars has a positional advantage that will allow it to participate in a useful way to support extractive activities on behalf of Earth in the asteroid belt and elsewhere. The mission to colonize Mars runs into three major challenges. 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. Even if Earth faces catastrophe, so long as there are people living on Mars, humanity has a future. People love those first tiny little rovers on Mars because they were public projects and everybody had a stake in it. The economics of colonizing Mars . Others have discussed microgravity’s effects on the human body, but Mars is not free-fall. “Establishing a colony on Mars is incredibly technically ... economic motivation for a Martian colony is for it to ... on the moon before Mars. Mars and Earth have very similar lengths of days. It's been done in the past, it'll be done in the future. All Rights Reserved. “Exploring and colonizing Mars can bring us new scientific understanding of climate change, of how planet-wide processes can make a warm and wet world into a barren landscape. I’m just the telephone operator that plugs in the various voices and they speak. or self reproducing machines, such as Turing machines or nanotechnology. Why would they want to do so?
