High Frontier, p63These were not to be single panes, but would be made up of many small sections, to prevent catastrophic damage, and so the aluminum or steel window frames can take most of the stresses of the air pressure of the habitat. [1], While teaching undergraduate physics at Princeton University, O'Neill set his students the task of designing large structures in outer space, with the intent of showing that living in space could be desirable. Instagram: @lawsofthecosmos You can experience this when y… [1] Occasionally a meteorite might break one of these panes. Agriculture, as noted above, is external to the colony proper, outside the residential cylinder. Take your favorite fandoms with you and never miss a beat. High Frontier, p112, Interior view of the Rama O'Neill cylinder mobile worldlet from the Arthur C. Clarke Rendezvous with Rama series, The habitat and its mirrors must be aimed at the sun. A hundred closed type colonies with twenty million people each would yield the requisite two billion for Side 3. The stage is called "The Final Frontier", and the exterior can be seen in a cutscene. O'Neill's project was not completely without precedent. Of these, it is estimated that a billion lived in subterranean colonies on the Moon. Nitrogen would also be included to add a further 30% of the Earth's pressure. ibid. The O’Neill “Island Three” habitat is a gargantuan cylinder with hemispherical end caps, 32 kilometers (20 miles) long and 6.4 kilometers (four miles) in diameter, with a habitable surface area of 325 square kilometers (125½ square miles) or 32,500 hectares (80,310 acres) supporting a population in the tens of millions. The basic element or building block of the “sky” panels is a cubical quartz glass prism 3.2 meters (10.4 feet) on a side, massing about 80 tonnes (90 tons). Several of the architectures were able to provide areas large enough to be suitable for human habitation. The above pic would have transparent panels between the "city" panels and reflective mirrors outside to provide sunlight for the city. The fall would take about five minutes 20 seconds and make one and one-third revolutions, with a terminal impact of 644 KPH (400 MPH). The colonies (sides) are based on the O'Neill cylinder design for space habitats. The habitat's industrial manufacturing block is located in the middle, to allow for minimized gravity for some manufacturing processes. Another billion were scattered among the various asteroid settlements and geosynchronous satellite stations. Please try again later. Zeon Namelist. This half-pressure atmosphere would save gas and reduce the needed strength and thickness of the habitat walls. Same can be said with G-Saviour. However, there are commonalities along with the Future Century timeline of Gundam such as the continuous existence of Earth nations as independent powers. People would be able to detect spinward and antispinward directions by turning their heads, however, any dropped items would appear to be deflected by a few centimetres.ibid. Individual colony pairs are known as Colonies, and a group of colonies that occupy a Lagrangian point are known collectively as a Side. Note: in chronological order with only animated and/or live action works. UC.0068 - 0079 - Mobile Suit Gundam: The Origin - OVA/Movie series set before Gundam 0079. 4 Brian K. Vaughan To Write The Movie A later NASA/Ames study at Stanford University developed an alternate version of Island One: the Stanford torus, a toroidal shape 1600|m|ft in diameter.[4]. ISBN 0-8117-0397-5. ... O'Neil Cylinder Habitat model for both shipsets. [5] Each cylinder has six equal-area stripes that run the length of the cylinder; three are transparent windows, three are habitable "land" surfaces. The science of the colonies is all based on the work of Gerard K. O'Neill (the most common type of colony in Gundam being the "O'Neill Cylinder" (Island-3) with "Island-1" types being more early built aging models by the time Gundam's story happens) and can be seen in almost every episode of every Gundam series that takes place in space (obviously when they're on the planet they don't show the space … The colonies run on a 24-hour clock set to the Universal Time Coordinate (Greenwich Mean Time adjusted to the Terrestrial equator), with “sunrise” at 06:00 UTC and “sunset” at 18:00 UTC. While it shares its name with fellow series Gundam 00, it is explicitly shown as a different universe. A solar power station (SPS) generating a gigawatt per hour is built into the port docking port. )Orbiting with one end facing the sun, it’s divided lengthwise into six alternating “ground” and “sky” panels, so only half of the inner surface is actually available for habitation. Any Terrestrial climate can be simulated, but generally the air temperature is held between 5° to 25° C (40° to 80° F) and averages 15° C (60° F), with a relative humidity of 40% to 60%—the temperate climate that southern California promises but seldom delivers. ...

In most instances, he merely referred to “populations in the millions” but on at least one occasion he stated: “Island Three … could support quite easily a population of ten million people.”Most of the Gundam references cite populations of three to ten million per colony, but the question is confused by the fact that there are two types of colonies: the “open type” colonies using the O’Neill design and the more efficient “closed type” colonies with twice the habitable area. While teaching undergraduate physics at Princeton University, O'Neill set his students the task of designing large structures in outer space, with the intent of showing that living in space could be desirable. The Gundam franchise was a major contributing factor to the fame of the O'Neil cylinder in Japan. Proceedings of the Symposium on the Role of the Vestibular Organs in Manned Spaceflight, NASA SP-77, 1965. Is that feasible? Since there are three such panels, each colony has 24 windows (1,536 sashes or 38,400 panes or 3,840,000 frames or 96 million prisms) containing a combined mass of about 7,680 megatonnes (8,640 megatons) of quartz glass. High Frontier, p63..64To permit light to enter the habitat, large windows run the length of the cylinder. Without this precession, and the zero angular momentum necessary to achieve it, the “sunflower” illumination scheme simply won’t work! (The O’Neill design specified solar power to supply the colony’s needs, but there’s another simple, effective and continuous sources of energy readily available, which is to run thermally conductive material from the interior to the exterior and from the north end cap to the south end cap and use the temperature differential—an extraterrestrial equivalent of “geothermal” power.). The six cities and their associated suburbs cover an area of 41.4 square kilometers (16 square miles) each. (See Bernal sphere. The drop-off is linear—at the 1.6-kilometer (one-mile) level, midway (45°) up the mountainside, the pseudo-gravity is 50% (½ G). The O’Neill cylinder design consists of two cylinders rotating in opposite directions on a bearing to mitigate the gyroscopic effect. [1] These would not be single panes, but would be made up of many small sections, to prevent catastrophic damage, and so the aluminum or steel window frames can take most of the stresses of the air pressure of the habitat. The same applies going “down” from the axis to the hull, except that the push is going to be upspin. You can calculate the acceleration that produces this pseudo-gravity using the formula F=rω²/g, where F is the resulting acceleration, r is the distance from the central axis, ω is the angular velocity (a constant equal to 2π times the number of rotations per second) and g is the acceleration due to gravity experienced on Earth (9.80665 m/s² or 32.174 ft/s²). If so, riding them would be murder, due to the same Coriolis effect that produces the artificial “gravity” at the hull. (On 12 September 2002, Julian H. Fong wrote me to note that, while the Gundam animation and artwork ignore it, there’s an important reason why O’Neill colonies must be ballistically coupled pairs. #6. Feb 18, 2014 @ 10:45pm whats a Ringworld O.o? Offers an alternate retelling of events that falls more in order with the story of the Gunda… Some examples of this are Lagrange points and the O’Neill cylinder and the fact that Helium-3 is used as an energy source. Instead, the ring remains fixed and each of the seventy-two agricultural blocks rotates at two RPM to produce Terrestrial gravity at its inner hull. Each docking port contains six docking bays, arranged around the axis like the chambers of a revolver. An O'Neill cylinder similar to those found in the Gundam series provides the setting for a stage in the game Tekken 5. “Linear trams” resembling the cable cars of San Francisco run up and down the end cap mountainsides, connecting the urban centers to the zero-G industrial blocks and bay blocks. If one habitat's rotation is slightly retarded, the two cylinders will rotate about each other. Katana70065 The space colonies from the "Mobile Suit Gundam" meta-series were O'Neill Cylinder colonies (most of them, anyway). Each dock can accommodate three 300-meter ships, for a total capacity of 108 ships. Set in a fictional universe in the Universal Century year 0079, the Principality of Zeon has declared independence from the Earth Federation, and subsequently launched a war of independence. This cooperative result inspired the idea of the cylinder, and was first published by O'Neill in a September 1974 article of Physics Today.[3]. T. A., Heppenheimer [1977] (2007). Setting aside the fact that Side 7 wasn't a full-fledged cluster, which could destroy the estimations if presented on its own, there's the fact that humanity is not locked in the Earth Sphere. (½ RPM is not very impressive visually, so the apparent rate of rotation is exaggerated to about two RPM in the animation. #8. They also allow for easy transport between ballistic coupled pairs of colonies, 80 kilometers (50 miles) apart, with a transit time of seven minutes and twenty-seven seconds (00:07:27) each way. By way of comparison, the Manhattan Borough of New York City is an elongated irregular strip twenty kilometers (12½ miles) long and four kilometers (2½ miles) wide. Population estimates of three to ten million per open type colony and six to twenty million per closed type colony are therefore most probably correct.The issue is further confused by the fact that O’Neill envisioned his colonies being built not as single units but as ballistically coupled pairs, 80 kilometers (50 miles) apart. Reply Oct 1, 2015 2050 AD: World War III ends between NATO and the Russian-Chinese-led … Docking ports called “bay blocks” at either end of the colony’s central axis rotate in the opposite direction, maintaining a “stationary” position around which the colony proper appears to rotate. The three “sky” panels are composed of quartz glass, vitreous silica prepared from pure quartz and noted for its transparency to ultraviolet radiation. The unhinged edge of the windows points toward the Sun. Once the plane formed by the two axes of rotation is perpendicular (in the roll axis) to the orbit, then the pair of cylinders can be yawed to aim at the sun by exerting a force between the two sunward bearings: away from each other will cause both cylinders to gyroscopically precess, and the system will yaw in one direction, towards each other will cause yaw in the other direction. During the day, the reflected Sun appears to move as the mirrors move, creating a natural progression of Sun angles. Zero-G industrial blocks are strung out along the axis between the docking ports and the end caps, standard-G industrial blocks are mounted on the exterior of the colony cylinder. Feb 18, 2014 @ 9:37pm Oooh, what about a ringworld? The counter-rotating habitats have no net gyroscopic effect, and so this slight precession can continue for the habitat's orbit, keeping it aimed at the sun.== See also ==* Dyson sphere* Bernal sphere* Centrifuge Accommodations Module* Globus Cassus* Stanford torus* Space stations and habitats in popular culture, * {{cite book  | last = T.
