earth ring space

In the close of Arthur C. Clarke's Fountains of Paradise (1979), a reference is made to an orbital ring that is attached in the distant future to the space elevator that is the basis of the novel. By precessing the ring once every 24 hours, the Orbital Ring will hover above any meridian selected on the surface of the Earth. The ring measures 2.6 million light-years across. If such a structure were built it could indeed provide a huge habitable inner surface, but the energy required to construct it and set it rotating is so significant (several centuries' worth of the total energy output from the Sun) that without as-yet unimagined energy sources becoming available, it is hard to see how this construction could ever be possible in a time frame acceptable to humans. The Ringworld is an artificial ring about one million miles wide and approximately the diameter of Earth's orbit (which makes it about 600 million miles in circumference), encircling a Sol-type star. When the planet Thea crashed into the earth, a titanic amount of material was blown into space. The opening battle of Star Wars: The Clone Wars's Season 6 pilot takes place on some form of ring-shaped orbital space station surrounding the planet of Ringo Vinda. The second iteration of the anime series Tekkaman features a complete ring, though abandoned and in disrepair due to war, and without surface tethers. The Ringworld is described as having a mass approximately equal to the sum of all the planets in our solar system. Although it might appear that Earth is located within Saturn’s outermost rings, that positioning is just an illusion created by the enormous distance between Cassini and Earth. Most notably as both Scrith and Twing can be reshaped to pass through thanks to a softening device (Pak) or a cziltang brone per the Ringworld. Paul Birch published a series of three articles in the Journal of the British Interplanetary Society in 1982 that laid out the mathematical basis of ring systems. The tensile strength of scrith is similar to the strong nuclear force, with the Ringworld foundation only about 30m (100 ft) deep. When the velocity of the string exceeds 10 km/sec, centrifugal forces detach the string from the Earth's surface and lift the ring into space. Walls 1000 miles tall along the edges retain the atmosphere. In fact, the earth did once have a ring—as part of the formation of our moon, ironically enough. It is inhabited by a number of different evolved hominid species, as well as Bandersnatchi, Martians and Kzinti. https://serc.carleton.edu/introgeo/earthsystem/nutshell/space.html [1][2] The orbital ring concept requires a method of stabilizing the ring. For naturally occurring rings, see. https://www.nationalgeographic.com/science/space/solar-system/earth Also, a whole network of orbital rings can be built, which, by crossing over the poles, could cover the whole planet and be capable of taking over most freight and passenger transport. Other science fiction authors have devised their own variants of Niven's Ringworld, notably Iain M. Banks' Culture Orbitals, best described as miniature Ringworlds, and the ring-shaped Halo structure of the video game series of the same name. Space Ring Could Shade Earth and Stop Global W A wild idea to combat global warming suggests creating an artificial ring of small particles or spacecrafts around Earth … Niven himself thinks of the Ringworld as "an intermediate step between Dyson spheres and planets.". These absorb a huge amount of sunlight energy, which is beamed to the Ringworld as its primary source of power. Scrith is said to have been artificially produced through the transmutation of matter. The shadow squares provide another of the imperfections "clarified" in Ringworld's Children, as five shadow squares of greater length, orbiting retrograde would provide a better day-night cycle, with less twilight. What if Earth had rings? In the ring-satellite cycle model, satellites form from the outer edge of the ring, and then migrate outward through gravitational interaction with the ring. These are artificial planets that would be supported by a grid of orbital rings that would be positioned above a planet, supergiant or even a star.[9]. This is where weather and … Scrith, usually written italicized as scrith, forms the walls and floor of the Ringworld. In 1963, the United States launched half a billion whisker-thin copper wires into orbit in an attempt to install a Earth's moon is 2,159 miles (3,474 km) wide, about one-fourth of Earth's diameter. Dendrochronology is a fancy word for tree-ring dating, where the age of a tree can be determined by the number of growth rings across its trunk. Due to its enormous strength, scrith is impervious to most weapons. https://www.space.com/what-if-earth-had-rings.html?utm_campaign=meetedgar&utm_medium=social&utm_source=meetedgar.com See the moon's shadow on Earth from the 'ring ... - Space.com The structure is intended to be used as a space station or as a planetary vehicle for very high speed transportation or space launch. This means that using the Orbital Ring concept, one or many pairs of Stations can be positioned above any points on Earth desired, or can be moved everywhere on the globe. Although this simple model would work best above the equator, Paul Birch calculated that since the ring station can be used to accelerate the orbital ring eastwards as well as hold the tether, it is therefore possible to deliberately cause the orbital ring to precess around the Earth instead of staying fixed in space while the Earth rotates beneath it. The Ringworld is an artificial world with a surface area three million times larger than Earth's, built in the shape of a giant ring-shaped ribbon a million miles wide and with a diameter of 186 million miles. The anime series Kiddy Grade also uses orbital rings as a launch and docking bay for spaceships. This ring effectively provides near unlimited power to earth. The third part of Neal Stephenson's book Seveneves has an orbital ring around a moon-less earth. As revealed in Ringworld Engineers, the "shadow squares" also provide a shielding to the inner surface of the Ringworld when someone in the control room uses a magnetic field embedded in the Ringworld to fire the meteor defense system. The original orbital ring concept is related to the space fountain, space elevator and launch loop. These rings are connected to large towers extending from the planets surface. They are also not in inertial orbit, and must be actively stabilized as well. Scrith is a milky-gray translucent, nearly frictionless material. Space junk can be bad news for an orbiting satellite. The anime Mobile Suit Gundam 00 also prominently features an orbital ring, which consists primarily of linked solar panels. A detailed description of the concept was proposed and analyzed by Paul Birch in 1982, proposing a massive ring that would encircle the globe in low orbit, from which cables hang down to the Earth's surface.[3][4][5]. It is the largest man made structure in the galaxy. The Moonis an average of 238,855 miles (384,400 kilometers) away. To provide an approximation of the day–night cycle common to planets, Ringworld was also provided with a separate ring of "shadow squares" linked together (by "shadow square wires") in a ring close to the star, rotating at slightly faster than the Ringworld's spin, providing a lot of twilight, as well as a day-night cycle. The ring is connected to earth via three space elevators. Once it reaches the Roche Limit of the Earth, about 9,500 km, our planet’s gravity will tear the Moon apart into a ring. Men's Wedding Bands & Rings View our broad selection of men's wedding bands in styles ranging from classic to unique designs. The system's cost per kilogram to place payloads in orbit would be around $0.05.[8]. https://www.planetary.org/space-images/cosmos-earth-with-a-ring-system Earth's moon is also visible to the left of our planet in a cropped, zoomed-in version of the image (Figure 1). The physical composition of scrith is unclear, but it appears to share some of the properties of a metal (albeit in a greatly exaggerated form): for instance, the high tensile strength, the ability to conduct heat and the ability to retain an induced magnetic field. The adventurers surmised that its construction consumed literally all the planets in that system, down to the last asteroid and/or moon, as the Ringworld star has no other bodies in orbit. https://larryniven.fandom.com/wiki/Ringworld?oldid=5570, G3 verging on G2; "barely smaller and cooler than, 7.5 Ringworld days (225 hours, 9.375 Earth days), On Ringworld, time longer than a day is measured in. Paul Birch published a series of three articles in the Journal of the British Interplanetary Society in 1982 that laid out the mathematical basis of ring systems.[3][4][5]. Our own moon is a very safe 236,000 miles (380,000 km) away. He notes in the dedication of Ringworld Engineers that at the 1971 World Science Fiction Convention MIT students crowded the hotel hallways chanting "The Ringworld is Unstable!" A body (such as a comet or asteroid) striking with enough kinetic energy may be able to deform the Ringworld floor and punch a hole, theFist of God mountain on the Ringworld was produced by exactly this type of event. It is true that we have a cloud of debris in orbit, mostly organized into a low earth orbit shell and a ring around and above geosynchronous orbit. Orbital debris, or “space junk,” is any man-made object in orbit around the Earth that no longer serves a useful purpose. A new image from NASA's Cassini spacecraft shows planet Earth as a point of light between the icy rings of Saturn. The planet Medusa also has such a ring, called Telstarax, hailing from the Dark Age of Technology, but it is largely plundered and wrecked. By an array of elevators and several geostationary ring stations, asteroid or Moon material can be received and gently put down where land fills are needed. Including both diamond , gemstone , and classic metal bands, our timeless wedding rings for men are the perfect symbol of the love you share. The tensile strength of the material required would be on the same order as the strong nuclear force, according to Niven — since the artificial gravity is the same as normal gravity, the structure is comparable with a bridge with an extremely long span; nothing even remotely strong enough is known to exist in nature. In the simplest design of an orbital ring system, a rotating cable or possibly an inflatable space structure is placed in a low Earth orbit above the equator. The manga Battle Angel Alita (1990-1995) prominently features a slightly deteriorated orbital ring. It rotates, providing an artificial gravity equivalent to 99.2% of Earth's gravity by way of Centrifugal force. A. Meulenberg and P. S. Karthik Balaji, "The LEO Archipelago: A system of earth-rings for communications, mass-transport to space, solar power, and control of global warming", Journal of the British Interplanetary Society, "Nonlinear Dynamics of Ringworld Systems", "Orbital Ring Systems and Jacob's Ladders - I-III", MegaStructures 01: Orbital Rings & Space Elevators, String Transport Systems: on Earth and in space, https://en.wikipedia.org/w/index.php?title=Orbital_ring&oldid=991493266, Creative Commons Attribution-ShareAlike License, Eccentric orbital ring systems – these are rings that are in the form of a closed shape with varying altitude, This page was last edited on 30 November 2020, at 10:17. Though the ring itself is rotating at 1200 km/s (to approximate Earth gravity), the center of mass is stationary — in fact, it is at an unstable equilibrium, roughly comparable to a small sphere balanced on top of a larger one. Saturn and its spectacular rings, as imaged by the Hubble Space Telescope on July 4, 2020. The researchers spotted the ring unexpectedly while they were mapping the distribution of dark matter within the galaxy cluster Cl 0024+17 (ZwCl 0024+1652), located 5 billion light-years from Earth. In later novels the "transmutation" idea is simply discarded and the construction method of scrith left open, although one engineer (Tunesmith) is able to use nanotechnology to weave new scrith into meteor punctures. In the movie Starship Troopers, an orbital ring is shown encircling the Moon. Paul Birch, "Orbital Ring Systems and Jacob's Ladders - I". A simple unsupported hoop about a planet (or a star) is unstable: it would crash into the central body if left unattended. The rings visible here are the A ring (at top) with the Keeler and Encke gaps visible, and the F ring (at bottom). One of the large oceans, known as the "Great Ocean", contains one-to-one maps of all of the inhabited worlds of known space. Ringworld has a habitable flat inner surface equivalent in area to approximately three million Earth-sized planets. Hanging down from these ring stations are short elevator cables made from materials with high-tensile-strength-to-mass-ratio. This is not the perfect match for a planet however, as there is no sunrise or sunset in Ringworld, and when not covered by a shadow square, the sun is always at high noon. Earth Planet Earth as of 100000 CE, the rings were built in 13728 CE to celebrate Vega becoming the new North Star. On opposite sides of the ring are two large deep saltwater oceans, placed in counterbalance to one another. Thus, large thrusters must be incorporated into the design to keep it centered about its star. It is inhabited by a number of different evolved hominid species, as well as Bandersnatchi, Martians and Kzinti. Take your favorite fandoms with you and never miss a beat. An overview[7] mentions four applications of orbital rings. Anatoly Yunitskiy, "в космос на колесе" ("To Space by Wheel"). A "Ringworld", or more formally, a "Niven ring", has become the generic term for such a structure, which is an example of what science fiction fans call a "Big Dumb Object", or more formally a megastructure. It was built by the Pak, who later through infighting left it mostly Protector free. With a radius of 1,079.6 miles (1,737.5 kilometers), the Moon is less than a third the width of Earth. If Earth were the size of a nickel, the Moon would be about as big as a coffee bean. Our planet has one moon, while Mercury and Venus have none and all … In the fourth book in the series, Ringworld's Children, he creates backplot explanations for several of the imperfections in his original design of the Ringworld — and wholly glosses over others, such as that Louis Wu is worried about his dietary intake of salt since only the Great Oceans are described as being saline. It also absorbs nearly 100% of all other radiation and subatomic particles and rapidly dissipates heat. Not in orbit, but riding on this ring, supported electromagnetically on superconducting magnets, are ring stations that stay in one place above some designated point on Earth. Also, it is transparent to large magnetic fields. A ringworld design requires active stabilization, because it is not in inertial orbit. The "Other Ocean" has many maps of a single world: the Pak Homeworld. In the Warhammer 40,000 universe, Mars has a large orbital ring called the Ring of Iron. Paul Birch, "Orbital Ring Systems and Jacob's Ladders - III". The Ringworld is an artificial world with a surface area three million times larger than Earth's, built in the shape of a giant ring-shaped ribbon a million miles wide and with a diameter of 186 million miles. (This merely gives a name to the sufficiently advanced technology that would have to be used.) In the game Xenoblade Chronicles 2 there is a giant tree that has grown around the base of an Orbital Ring. In Ringworld's Children it is additionally explained that it took the reaction mass of roughly 20 Jupiter masses to spin up the ring; thus the combined mass of the planets of the original system was that much larger than our solar system's. The construction of a ringworld remains firmly in the area of speculation. The game X3 Terran Conflict features a free-floating orbital ring around the Earth, which is shattered by an explosion and subsequently de-orbited in X3: Albion Prelude. In 1982 the Belarusian inventor Anatoly Yunitskiy also proposed an electromagnetic track encircling the Two other types were also defined by Paul Birch: In addition, he proposed the concept of "supramundane worlds" such as supra-Jovian and supra-stellar "planets". Paul Birch, "Orbital Ring Systems and Jacob's Ladders - II". The Moonis slowly moving away from Earth, ge… Recently in Destroyer of Worlds (novel) it was revealed that by combining aspects of the Pak building material twing, itself an incredibly durable programmable substance, with the theory of resonant molecule bonds could produce something akin to Scrith. The relatively thin layer of scrith that forms the floor of the Ringworld blocks the passage of 40% of the neutrinos that encounter it, equivalent to almost a light year of lead. This point gave Niven some difficulty after he published his first Ringworld novel; he was deluged with letters pointing out that "the Ringworld isn't stable" and dedicated the first sequel to a resolution of this problem. It is primarily used as a shipyard for interstellar craft. Later in the series the ring also shows space stations mounted on its surface. https://www.jpl.nasa.gov/images/earth-between-the-rings-of-saturn The simplest type would be a circular orbital ring in LEO. In Niven's Ringworld novels, the material—which he calls scrith—is said to have been artificially produced through the transmutation of matter into the required substance. The cables which dangle from the ring are now geostationary without having to reach geostationary altitude, or without having to be placed into the equatorial plane. Arthur C. Clarke's 3001: The Final Odyssey (1997) features an orbital ring held aloft by four enormous inhabitable towers (assumed successors to space elevators) at the Equator. Orbital rings are used extensively in the collaborative fiction worldbuilding website Orion's Arm.[10]. The Ringworld engineers used a device, called the cziltang brone in their language, to pass from the vacuum of their spaceports right through the scrith to the habitable surface of the Ringworld. A Cross Section Through the Floor of The Ringworld. Thus, any point on Earth can be served by a space elevator. The Moon is farther away from Earth than most people realize. On February 11, 2009, a U.S. communications satellite owned by a private company called Iridium collided with a non-functioning Russian satellite. An asteroid or comet would have to venture very close to the Earth to be torn apart by tidal forces and form a ring around the Earth. Andrew Meulenberg and his students, from 2008 to 2011, presented and published a number of papers based on types and applications of low-Earth-orbital rings as humanity's "stepping-stones-to-space". The majority of the surface is land interspersed with shallow, freshwater seas. https://www.damninteresting.com/earths-artificial-ring-project-west-ford In 1982, Soviet inventor Anatoly Yunitskiy also proposed an electromagnetic track encircling the Earth, which he called "by wheel into space"[6] (later, "String Transportation System").
