THE FUTURIST, February 1976
An earth-like space colony could be orbiting our world by 1990,says a Princeton University physicist. The colony�s 10,000 inhabitantswould enjoy green plants, animals, plains, valleys, hills, and streams.The colonists would pay offthe cost of building their extraterrestrialhome by manufacturing satellite solar power stations, which would supplycheap, virtually inexhaustible power to the earth.
Author Gerard O�Neill, Professor ofPhysics at Princeton University,hopes that space colonization will be a cooperative international program,bringing world peace a step closer. |
During the past decade, a number of premises about thebasic problems of the world have become very widely accepted. The moreimportant of these accepted ideas are:
- For the foreseeable future, every significant human activitymust be confined to the surface of the earth.
- The material and energy resources of the human race are justthose of our planet.
- Any realistic solutions to our problems of food, population,energy, and materials must be based on a kind of zero-sum game, in whichno resources can be obtained by one nation or group without being takenfrom another.
In my opinion, based on studies carried out at PrincetonUniversity, these three basic premises on which most discussions of thefuture have been based are simply wrong. The human race stands now on thethreshold of a new frontier whose richness is a thousand times greaterthan that of the new western world of 500 years ago.
That frontier can be exploited for all humanity, and itsultimate extent is a land area many thousands of times that of the entireearth. As little as 10 years ago we lacked the technical capability toexploit that frontier. Now we have that capability, and if we have thewillpower to use it, we can not only benefit all humanity, but also spareour threatened planet and permit its recovery from the ravages of the industrialrevolution.
The high frontier which I will describe is space, butnot in the sense of the Apollo program, a massive effort whose main lastingresults were scientific. Nor is it space in the sense of the communicationsand observation satellites, useful as they are. Least of all is it spacein the sense of science-fiction, in which harsh planetary surfaces weretamed by space-suited daredevils. Rather, it is a frontier of new lands,located only a few days travel time away from the earth, and built frommaterials and energy available in space.
Space Colonies: The Basic Plan
The central ideas of space colonization are:- To establish a highly-industrialized, self-maintaininghuman community in free space, at a location along the orbit of the mooncalled L5, where free solar energy is available full time.
- To construct that community on a short time scale, withoutdepending on rocket engines any more advanced than those of the space shuttle.
- To reduce the costs greatly by obtaining nearly all ofthe construction materials from the surface of the moon.
- At the space community, to process lunar surface raw materialsinto metals, ceramics, glass, and oxygen for the construction of additionalcommunities and of products such as satellite solar power stations. Thepower stations would be relocated in synchronous orbit about the earth,to supply the earth with electrical energy by low-density microwave beams.
- Throughout the program, to rely only on those technologieswhich are available at the time, while recognizing and supporting the developmentof more advanced technologies if their benefits are clear.
The two key factors that make space colonization aneconomically sound idea are solar energy and lunar materials. As everyoneknows, the sun is a virtually inexhaustible source of clean energy. Onearth, solar energy use is hampered by nighttime, by seasonal variationin the day-length, and by clouds; in space, solar energy is always available,and also much more intense. The amount of solar energy which flows unused,in a year, through each square meter of free space is 10 times as muchas falls on an equal area in even the most cloud-free portions of Arizonaor New Mexico. A solar-energy installation in space, therefore, is potentiallyable to operate at a tenth the cost at which it could operate on earth.
The cost of space colonization could be reduced furtherby obtaining construction materials from the moon. On earth, we are the'gravitationally disadvantaged.' We are at the bottom of a gravitationalwell 4000 miles deep, from which materials can be lifted into space onlyat great cost. The energy required to bring materials from the moon tofree space is only one twentieth as much as from the earth, and Apollosamples indicate that the moon is a rich source of metals, glass, oxygen,and soil. The moon�s lack of an atmosphere reduces further the cost oftransporting lunar materials to orbiting space colonies.
Lunar surface raw materials, would be transported by alaunching device called a mass driver; it exists now only on paper, butit can be designed and built with complete assurance of success becauseit requires no high-strength materials, no high accelerations or temperatures,and its principles are fully understood. The mass driver would be a linearelectric motor, forming a thin line several miles long, which would acceleratesmall 10-pound vehicles called buckets to lunar escape velocity, at whichtime they would release their payloads and then return on a side trackfor reuse. Warp 3.3 pro. The mass driver would be an efficient machine, driven by a solar-poweredor nuclear electric plant.
The wheel-like design shown above (and also onthe cover) might be used for the first space colony. The mirror floatingabove the colony reflects sunlight into the ring mirrors below, which reflectit through 100-foot strip windows into the colony�s interior for lightand agriculture. Above the core sphere are communications and spacecraftdocking facilities. Long rectangle in foreground is a heat radiator. Thefacility below the colony is the manufacturing area where lunar ore ismelted with solar power. Lower central sphere is the original 'constructionshack' for the colony.
Building the First Colony
If we were to start now, with determination and drive, Ibelieve that the first space colony (Island One) could be in place, withits productive capacity benefiting the earth, before 1990. This is possible,I must emphasize, within the limits of present-day, conventional materialsand technology.A modified space shuttle and a chemical space tug wouldbe used to transport basic construction equipment, supplies, and 2,000workmen to a point in space called L5. (L5 is a point in the moon�s orbitequidistant from the earth and the moon at which objects will remain ina stable orbit, stationary with respect to the moon.) A smaller work forceof about 200 people would establish a lunar outpost which would provide98% of the raw materials needed for the construction of Island One.
The mass driver, operating only 25% of the time, couldlift 500,000 tons of material to L5 in the six-year construction time ofIsland One. An identical machine, located in space, could be a very effectivereaction motor for the shifting of heavy payloads in the 100,000-ton range.
Lunar soil is 40% oxygen, 19.2% silicon, 14.3% iron, 8%calcium, 5.9% titanium, 5.6% aluminum, and 4.5% magnesium. The aluminumwould be the primary building material and the oxygen would be used asatmosphere and to fuel rocket engines. Lunar surface materials are poorin carbon, nitrogen, and hydrogen, which would have to be brought fromearth. For every ton of hydrogen brought from earth, nine tons of watercould be made at the colony site, using oxygen from the processing of lunaroxides.
The removal of half a million tons of material from thesurface of the moon sounds like a large-scale mining operation, but itis not. The excavation left on the moon would be only five meters deepand 200 meters long and wide, not even enough to keep one small bulldozeroccupied for a five-year period.
In the long run, we can use the fact that the asteroidsare also a source of materials. The three largest asteroids alone containenough materials for the construction of new lands with a total area manythousands of times as large as that of the earth. Once the asteroidal resourcesare tapped, we should have not only metals, glass, and ceramics, but alsocarbon, nitrogen, and hydrogen. These three elements, scarce on the moon,are believed to be abundant in the type of asteroid known as carbonaceouschondritic.
Island One
Within the materials limits of ordinary civil engineeringpractice and within an overall mass budget of 500,000 tons (about the sameas the mass of a super-tanker), several designs for the first 'island inspace' have evolved. All are pressure vessels�spherical, cylindrical, ortoroidal�containing atmospheres with the same oxygen content as at sealevel on earth and rotating slowly to provide a gravity as strong as thatof the earth. The axis of the structure would always point toward the sun,the source of all the energy used by the colony.The first space community would house 10,000 people; 4,000would be employed building additional colonies, while 6,000 would be producingsatellite solar power stations. The interior of the colony will be as earth-likeas possible�rich in green plants, trees, animals, birds, and the otherdesirable features of attractive regions on earth. The design would allowa line of sight of at least a half mile, giving the residents a feelingof spaciousness. Widsmob viewer pro 1.2.1018 update. The landscape would feature plains, valleys, hills, streams,and lakes. The residential areas might consist of small apartment buildingswith big rooms and wide terraces overlooking fields and groves. Near theaxis of the structure, gravity would be much reduced and, consequently,human-powered flight would be easy, sports and ballet could take on a newdimension, and weight would almost disappear. It seems almost a certaintythat at such a level a person with a serious heart condition could livefar longer than on earth, and that low gravity could greatly ease manyof the health problems of advancing age.
The space colony would have separate residential, agricultural,and industrial areas, each with its optimal gravity, temperature, climate,sunlight, and atmosphere. Intensive agriculture would be possible, sincethe day-length and seasonal cycle would be controllable independently foreach crop and care would be taken not to introduce into the agriculturalareas the insect pests which hamper earth agriculture. Agriculture couldbe efficient and predictable, free of the extremes of crop failure andglut which the terrestrial environment forces on our farmers. Only 111acres would be needed to feed all 10,000 residents.
Energy Without Guilt
Energy for agriculture would be used directly in the formof sunlight, interrupted at will by large, aluminum shades located in zerogravity in space near the farming areas. An advanced sewage system wouldquickly and efficiently turn wastes into pure water and agricultural chemicals.The air, constantly filtered, would be cleaner than in any city on earth.Non-polluting light industry would probably be carriedon within the living-habitat, convenient to homes and shops. Heavy industry,though, could be located in nearby external non-rotating factories becauseof the advantages of zero gravity. The combination of zero gravity andbreathable atmospheres would permit the easy assembly�without cranes, lift-trucks,or other handling equipment�of very large, massive products. These productscould be the components of new colonies, radio and optical telescopes,large ships for the further exploration of the solar system, and powerplants to supply energy for the earth. Within a century, other industriesmight be shifted to space colonies because of the abundant, free, pollutionlessenergy supply and the greater efficiency made possible by zero gravityand the vacuum of space.
Process heat for industry, at temperatures of up to severalthousand degrees, would be obtainable at low cost, simply by the use ofaluminum-foil mirrors to concentrate the ever-present sunlight. In space,a passive aluminum mirror with a mass of less than a ton and a dimensionof about 100 meters, could collect and concentrate, in the course of ayear, an amount of solar energy which on earth would cost over a milliondollars at standard electricity rates.
Electrical energy for a space community could be obtainedat low cost, within the limits of present technology, by a system consistingof a concentrating mirror, a boiler, a conventional turbogenerator, anda radiator, discarding waste heat to the cold of outer space. It appearsthat, in the environment of a space community, residents could enjoy aper capita usage of energy many times larger even than what is now commonin the United States, but could do so with none of the guilt which is nowconnected with the depletion of an exhaustible resource.
Gerard O�Neill offers the following reasonswhy a colony in space is more practical than one on the surface of themoon:
The analogy that I use is that in our old-fashionedtalk about colonizing planetary surfaces, we were rather like a small animalwhich was deep down in a hole in the ground. The animal climbs at greatcost up to the top of the hole and looks out and sees all the grass andflowers and sunshine, and walks across the grass. Then he finds anotherhole and climbs down to the bottom of that hole again: And in gravitationalterms that is exactly what we are doing if we go into free space and thenclimb down again to the surface of the moon. The transport costs to get to the moon are about twiceas high as they are to go out into free space; that means that the capitalizationfor productive equipment is up by the same factor of 2. |
Shape of Future Colonies
While the first space colony will probably be a torus (awheel-shaped structure), later colonies will be cylinder-shaped. The mainreason for the change is that the first colony will be by far the mostexpensive to produce and the torus will cost less to construct. Once thefirst colony is in place, the initial investment in equipment and materialsfrom earth will not need to be repeated; consequently, the cost of colonyconstruction will drop drastically. The cylindrical design, consideredthe most efficient, will then be as easy to build as the torus.Each colony would consist of a pair of cylinders, connectedby cables and spinning in opposite directions so that the total systemwould have almost no spin. Alternating stripes of land and window areaswould run the length of the cylinders; the cylinder walls would be madeof aluminum and glass. Agriculture would be housed in auxiliary capsulesconnected to the cylinders.
The smallest cylindrical colony, like the torus, wouldsupport 10,000 people. Each cylinder would be 3,280 feet long and 328 feetwide. A Model II colony would have three times more area and as many as100,000 people, and would be less dependent on earth for resources. ModelIII, which might be built early in the next century, would be so largethat a portion of the island of Bermuda or a section of the Californiacoast like Carmel could fit easily within one of its 'valleys.' Model IIIresidents would begin mining the asteroid belt for resources and wouldno longer need to import any materials from earth.
A Model IV colony consisting of two cylinders, each 19miles long and four miles in diameter, could house several million peoplecomfortably. Its atmosphere would be deep enough to include blue skiesand clouds. The endcaps of the cylinders could be modeled into duplicatesof a mountain range such as the Grand Tetons, with 8,000-foot peaks. Areflected image of the ordinary disc of the sun would be visible in thesky, and the sun�s image would move across the sky from dawn to dusk asit does on earth. The land area of one cylinder could be as large as 100square miles.
Eventually, it may be possible to build even larger sphericalstructures with diameters of up to 12 miles and a total habitable landarea of 250 square miles.
The date of realization of Model IV colonies does notdepend on materials or engineering�those we have already. Rather, it dependson a balance between productivity, a rising living standard, and the economiespossible with automation. Under the space colony conditions of virtuallyunlimited energy and materials resources, a continually rising real incomefor all colonists is possible�a continuation rather than the arrest ofthe industrial revolution. Reasonable estimates of 3% per year for thereal income rise, 8% for interest costs, and 10% for automation advancesput the crossover date (the date when large colonies become economicallyfeasible) about 40 to 50 years from now�well within the lifetimes of mostof the people who are now alive.
The largest (Model IV) space colonies, whichcould he functioning by 2025, will probably consist of two connected cylinders,each 19 miles long, four miles in diameter, and containing as much as 100square miles in total land area. The most beautiful living areas on earthcould be duplicated in the colonies. The bridge shown here, to give anidea of the dimensions involved, is similar in size to the San FranciscoBay Bridge. A Model IV colony could hold up to several million people comfortably,but the interior design pictured here is intended for only about 200,000people.
Night is approaching in this Model IV space colonycylinder, which is 19 miles long and four miles in diameter. The atmospherein the large colonies is deep enough to include blue skies and clouds.A reflected image of the sun moves across the sky from dawn to dusk. Theamount of light entering the cylinder is controlled by mirrors outsidethe stripes of window areas which alternate with the land areas in thecolony. The earth-like atmospheric effects make the colony seem more spaciousand natural.
First Colony Could Cost $100 Billion
The best estimate currently available is that the establishmentof Island One would cost $100 billion, with a possible variation of $50billion in either direction. That figure is 2.5 times the cost of ProjectApollo and 5-15% of the estimated cost of Project Independence, the U.S.energy self-sufficiency plan. To put the cost of the first space colonyin perspective, a list of approximate costs for other large-scale engineeringprojects (in 1975 dollars) follows:a) Panama Canal | |
b) Space Shuttle Development | $5.8 billion |
c) Alaska Pipeline | |
d) Advanced Lift Vehicle Development | $8-25 billion |
e) Apollo | |
f) Super Shuttle Development | $45 billion |
g) Manned Mission to Mars | |
h) Project Independence | $600-2000 billion |
The eventual cost of building the first colony will beaffected significantly by the following variables:
- Frequency and efficiency of crew rotation between the earthand L5, and between the earth and the moon, during the construction period.
- Extent of resupply needed during construction. This itemcan vary over a wide range, depending on the atmospheric composition neededat the construction station, and whether food is shipped in water-loadedor dry form.
- Atmospheric composition. The structural mass of Island Oneis proportional to the internal atmospheric pressure, but independent ofthe strength of artificial gravity produced by rotation. Nitrogen constitutes79% of earth�s atmosphere, but we do not use it in breathing. To providean earth-normal amount of nitrogen would cost us two ways in space colonyconstruction, because structure masses would have to be increased to containthe higher pressure, and because nitrogen would have to be imported fromthe earth. A final choice of atmospheric mix would be based on a more completeunderstanding of fire protection.
With these factors in mind, three different preliminarycost estimates have been made for construction of Island One. My own spartanestimate, $33 billion, would allow for no crew rotation, an oxygen atmosphere,little resupply, and small power plants (10Kg/Kw) on the moon and at L5.The NASA Marshall Space Flight Center made two independent cost estimatesfor the project last year. The initial estimate, $200 billion, includeschemical and nuclear tugs, super shuttle development, orbital bases, anoxygen/nitrogen atmosphere, extensive crew rotation, resupply at 10 poundsper man/day, and power plants at 100 Kg/kW. A later re-estimate, carryinga $140 billion price tag, eliminates unnecessary lift systems, but stillincludes the oxygen/nitrogen atmosphere, crew rotation, resupply at 10pounds per man/day, and power plants at 100 Kg/kW. The two NASA estimatesalso appear to include a contingency factor for problems not yet identified.
Noted science writer Isaac Asimov, in awritten statement submitted to the House Subcommittee on Space Scienceand Applications in August 1975, said, 'It is my opinion that the importantgoal for space exploration over the next century is the establishment ofan ecologically independent human colony on the Moon, or on artificialspace colonies that use the Moon as a quarry for raw materials. The reasonsfor this follow:
|
Energy for the Earth
Island One will pay for itself mainly by manufacturing satellitesolar power stations which would supply the earth with an inexhaustibleenergy supply. At present, both the industrial nations and the underdevelopedthird world nations are vulnerable to the threat of supply cutoff by theMiddle East oil-producing nations. The only permanent escape from thatthreat lies in developing an inexhaustible energy source with a cost lowenough to make synthetic fuel production economically feasible.Earth Space Colonies 1.0 Map
Nuclear power is moderately expensive (1.5 cents/KWH)and is accompanied by the problems of nuclear proliferation and radioactivewaste disposal. Fossil fuels are scarcer now, and intensive strip-miningfor coal will almost inevitably further damage the environment. Solar energyon the earth is an unreliable source, suitable for daytime peak loads inthe American southwest, but not clearly competitive in most applicationsat the present time.
For several years, design groups at Boeing Aircraft andat Arthur D. Little, Inc., have studied the concept of locating large solarpower stations in geosynchronous orbit�where sunlight is available 99%of the time�to convert solar energy to electricity and beam it by microwavesto earth, where it would be reconverted to ordinary electricity. Already,an overall transmission efficiency of 54% has been demonstrated in tests.The main stumbling block has been the problem of lift costs. Constructionof the satellite solar power station (SSPS) units at the space colony,using lunar materials to avoid the high lift costs from earth, would makesolar energy competitive with other energy sources even from the start,according to my calculations. Eventually, solar electric power rates wouldbe much lower than those of coal-fired or nuclear power plants. No thermal,chemical, or radioactive pollution would be created, and the microwaveintensity would not exceed official exposure limits.
If development of the space colonies proceeds on the fastestpossible time-scale (with intensive design beginning this year and majorconstruction of the first colony beginning in 1982), the program couldpay back all of the total investment (plus 10% interest) in 24 years. Thetotal investment cost includes the development and construction cost ofthe first colony; the cost of lifting the materials needed from the earthfor subsequent colonies and for non-colony-built SSPS components; a paymentin dollars on earth of $10,000 per person/year to every colonist, representingthat portion of salaries convertible to goods and services on earth (forsubsequent use on visits or, if desired, on retirement); and a carryingcharge of 10% interest on the total investment (outstanding principal)in every year of the program. The economic output of the program is measuredin the sale of solar power at initial rates of 1.5 cents per Kilowatt-hour,gradually dropping to one cent per Kilowatt-hour.
To produce the necessary number of power satellites withinthis time-scale, a total work force of 100,000-200,000 people would berequired. In our calculations, we assumed that the construction of thefirst colony would take six years; thereafter, each colony could replicateitself in two years.
Each colony would produce two SSPS units per year. Theproductivity implied, 13-25 tons/person-year, is similar to that of heavyindustry on earth. New colony construction would be halted after the 16thcolony, due to market saturation. In this scenario, the benefit/cost ratiowould be 2.7.
By the 11th year of the program (1993 on the fastest possibletime-scale), the energy flowing to the power grids on earth from L5-builtSSPS units could exceed the peak flow rate of the Alaska pipeline. By the13th year, the SSPS plants could fill the entire market for new generatorcapacity in the U.S. By year 17, the total energy provided could exceedthe total estimated capacity of the entire Alaska North Slope oil field.Given the rapid growth of the manufacturing capacity and the possibilityof power cost reductions, true 'energy independence' for the nations takingpart in the L5 project could occur before the year 2000, with a shiftto production of synthetic fuels.
Cooperative Multinational Program Is Desirable
There are, in my opinion, at least five or six nations orgroups of nations which possess the technical and economic ability to carryout the construction of Island One on their own. In my own view, I wouldlike to see a cooperative multinational program formed, based on participationby all interested nations. It would be in the interest not only of theenergy-consuming industrial nations, but also of the oil-producing nationsto take part in the program, since it would result in a drastic drop inthe market value of Middle Eastern oil before the end of this century.A cooperative international program could have a real stabilizing effecton world tensions.It would be naive to assume that the benefits of spacecolonization will be initially shared equitably among all of humanity,but the resources of space are so great that those who are first to exploitthem can well afford to provide the initial boost that will allow theirless advantaged fellow humans to share the wealth. Suddenly given a newworld market of several hundred billion dollars per year, the first groupof nations to build space manufacturing facilities could easily divertsome fraction of the new profits to providing low-cost energy to nationspoor in mineral resources, and to assisting underdeveloped nations by providingthem with initial space colonies of their own. The resources of space areso great that even those nations which achieve the ability to use themonly after a long delay will still find an abundance remaining. It shouldalso be emphasized that the provision of unlimited low-cost energy to thedeveloping nations will probably be the most effective contribution wecould make to solving the world�s food problem, because the cost of chemicalsfor high-yield agriculture is almost entirely the cost of energy for theirproduction.
If we use our intelligence and our concern for our fellowhuman beings in this way, we can, without any sacrifice on our own part,make the next decades a time not of despair, but of fulfilled hope, ofexcitement, and of new opportunity.
'The human race stands now on the thresholdof a new frontier whose richness is a thousand times greater than thatof the new western world of 500 years ago.'
Public Response Is Favorable
The evidence of the past year indicates that, in terms ofpublic response, space colonization may become a phenomenon at least aspowerful as the environmental movement. Since the first small, informalconference in May, 1974, a rapidly increasing number of articles aboutit have appeared in newspapers and magazines, and all have been quite favorable.Radio and television coverage has also increased rapidly.A volunteer organization in Tucson, Arizona, recentlyspent an intensive week trying to get information to people about the spaceproject, and two weeks later carried out a random sampling telephone survey.They report that 45% of the people in that city now know about this project,and of those who know about it, two-thirds of them are already in favorof it.
The mail that I get�from many nations around the world,as well as the United States�runs 100-to-1 in favor of the project. Also,encouragingly, less than 1% of all mail is in any way irrational. Manyof the correspondents have offered volunteer help, and are actively workingat the present time in support of the space colonization concept. The lettersexpress the following reasons why this concept, in contrast to all otherspace options now extant, is receiving such broad support:
- It is a right-now possibility. It could be realized withinthe immediate future.
- In contrast to the elitism of the Apollo project or a mannedmission to Mars, it offers the possibility of direct personal participationby large numbers of ordinary people. Many of the correspondents, from hard-hatconstruction workers to highly-educated professional people, see themselvesas prospective colonists.
- In contrast to such technical options as the supersonic transport,nuclear power, or the strip-mining of coal, it is seen as offering thepossibility of satisfying real needs while preserving rather than furtherburdening the environment.
- It is seen as opening a new frontier, challenging the bestthat is in us in terms of technical ability, personal motivation and thedesire for human freedom. Many correspondents refer to space colonizationby analogy to the discovery of the New World or to the settlement a centuryago of the American frontier.
'The evidence of the past year indicates that,in-terms of public response, space colonization may become a phenomenonat least as powerful as the environmental movement.'
During the past year, Gerard O�Neill�sspace colonization concept has captured the imagination of a rapidly increasingnumber of people. He reports that he gets more mail than he can answer,and 99% of the letters are favorable. Last July, O�Neill�s testimony also impressed the Subcommitteeon Space Science and Applications of the U.S. House of Representatives.Near the end of the testimony, Subcommittee Chairman Don Fuqua (a FloridaDemocrat) said of the space colonization project, 'It�s something thatwill happen, and even though it kind of boggles the mind at the presenttime, it is not beyond the realm of possibility. I hope I live to see it.'The Subcommittee concluded, in its official report, that orbital colonieswere 'potentially feasible' and deserving of close examination. it alsostated that 'concepts and methods for the space-based generation of electricity,using energy from the sun, should be developed and demonstrated as a significantcontribution to solution of the fossil fuel dilemma.' Finally, the Subcommittee gave its support to 'an expandedspace program in FY 1977-1978, at least 25% greater than current funding,to undertake new space initiatives.' Fuqua later said that '.. bold newspace programs; the possibility of space colonization, based on realisticappraisals of potential space progress, deserve serious consideration.It's apparent that the imagination, skill, and technology exists to expandthe utilization and exploration of space.' Astronomer Carl Sagan, testifying before the subcommittee,declared that 'our technology is capable of extraordinary new venturesin space, one of which is the space city idea, which Gerard O'Neill hasdescribed to you. That�s an extremely expensive undertaking, but it seemsto me historically of the greatest significance. The engineering aspectsof it as far as I can tell are perfectly well worked out by O�Neill�s studygroup. It is practical.' O�Neill says that Wernher von Braun has also expressedinterest in his project. The space colony idea also was examined last year by 28physical and social scientists participating in the NASA/ASEE/StanfordUniversity 1975 Summer Study at the Ames Research Center in Mountain View,California. The 10-week study was sponsored by NASA�s Ames Research Center,Stanford University, and the American Society for Engineering Education(ASEE). The group found no insurmountable problems that would prevent successfulspace colonization and recommended 'that the United States, possibly incooperation with other nations, take specific steps toward the goal ofspace-colonization.' A Princeton Conference on Space Manufacturing Facilitieswas hosted by O�Neill last May. The Proceedings will be published laterthis year. A number of technical papers supporting the space colonyidea have appeared recently, including 'R & D Requirements for InitialSpace Colonization' by T. A. Heppenheimer and Mark Hopkins (both of theSummer Study) and 'Space Production of Satellite Solar Power Stations,'an analysis by William Agosto, a project engineer with the Microwave SemiconductorCorporation, Somerset, New Jersey. University courses are beginning to be offered dealingwith various aspects of space colonization. Magoroh Maruyama of PortlandState University is teaching a course on Extraterrestrial Community Systems,which explores new cultural options; possible psychological and socialproblems; and alternative physical, architectural, environmental, and socialdesigns. Massachusetts Institute of Technology now has an undergraduatecourse in space systems engineering, emphasizing space colonies. Beginningthis May, futurist Dennis Livingston will teach a course at RensselaerPolytechnic Institute in Troy, New York, called 'Space Colonies: A TechnologyAssessment.' The course will cover technical, economic, moral, political,and social aspects of space colonies. The American Institute of Aeronautics and Astronauticsis lobbying for more congressional support for O�Neill�s project, and hewas a keynote speaker during the Institute�s Annual Meeting in Washington,D.C., on January 30. For those interested in keeping informed about the latestdevelopments in O�Neill�s space colonization efforts, several newslettersare now available. Gerard O�Neill puts out his own Newsletter on SpaceColonization periodically. The newsletter summarizes recent work, liststhe latest magazine articles and books dealing with space colonies, listslectures scheduled on the subject, reports on the status of the spacecolony group at Princeton University, and advises of future plans.

Another newsletter which reports on O�Neill�s ideas occasionally(as well as other space concepts) is the EARTH/SPACE Newsletter.EARTH/SPACE describes itself as a commercial space venture dedicatedto free space enterprise and 'focusing on market development and methodsof making space profitable to the commercial user.' The EARTH/SPACE Newsletteris available for $5 per year from EARTH/SPACE, 2319 Sierra, Palo Alto,California 94303. O�Neill received a small grant from NASA in 1975, buthe believes that additional funding this year of between 0.5 and 1.0 milliondollars is needed for basic research if the project is to continue to developat the fastest possible rate. |
Colonies Offer Freedom and Diversity
By about the year 2018, emigration to better land, betterliving conditions, better job opportunities, greater freedom of choiceand opportunity in small-scale, eventually independent communities couldbecome a viable option for more people than the population increase rate.The cultural diversity will be enormous (in exact contrast, I think, tothe way things are going on earth at the present time). By 2150, therecould be more people living in space than on earth. The reduction of populationpressures on earth, left possibly with only a few billionpeople, would allow the planet to recover from the ravagesof the industrial revolution. Earth might serve mainly as a tourist attraction�acarefully preserved monument to man�s origin. At the same time, tourismand trade among the colonies would be practical and desirable, insuringthe survival and growth of the colonies.From the vantage point of several decades in the future,I believe that our children will judge the most important benefits of spacecolonization to have been not physical or economic, but the opening ofnew human options, the possibility of a new degree of freedom, not onlyfor the human body, but much more important, for the human spirit and senseof aspiration.
'By 2150, there could be more people livingin space than on earth. . Earth might serve mainly as a tourist attraction�acarefully preserved monument to man's origin.'
Gerard O�Neill, Professor of Physics at Princeton University,is noted for his work in high-energy experimental particle physics. Heis the leading proponent of the space colonization concept, which he originatedin 1969. His address is Physics Department, Box 708, Princeton University,Princeton, New Jersey 08540. The foregoing article is based on the author�spresentation to the World Future Society�s Second General Assembly in June,1975, and on his testimony before Congress on July 23, 1975.
