Bishop Ring (habitat)
__NOTOC__ A Bishop RingRain Noe"Space Colony Form Factors, Part 3: The Stanford Torus and Beyond" ''Core77'', Aug. 07, 2015. Retrieved 28 May 2018. is a type of hypothetical rotating space habitat originally proposed in 1997 by Forrest Bishop of the Institute of Atomic-Scale Engineering.Forrest Bishop"Open Air Space Habitats" Institute of Atomic-Scale Engineering, 1997. Retrieved 28 May 2018. The concept is a smaller scale version of the Banks Orbital, which itself is a smaller version of the Niven ring.Adam Hadhazy"Could We Build a Ringworld?" ''Popular Mechanics'', Sep 4, 2014. Retrieved 28 May 2018. Like other space habitat designs, the Bishop Ring would spin to produce artificial gravity by way of centrifugal force. The design differs from the classical designs produced in the 1970s by Gerard K. O'Neill and NASA in that it would use carbon nanotubes instead of steel, allowing the habitat to be built much larger. In the original proposal, the habitat would be approximately 1,0 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Space Habitat
A space habitat (also called a space settlement, space colony, spacestead, space city, orbital habitat, orbital settlement, orbital colony, orbital stead or orbital city) is a more advanced form of living quarters than a space station or habitation module, in that it is intended as a permanent settlement or green habitat rather than as a simple way-station or other specialized facility. No space habitat has been constructed yet, but many design concepts, with varying degrees of realism, have come both from engineers and from science-fiction authors. The term ''space habitat'' sometimes includes more broadly habitats built on or in a body other than Earth—such as the Moon, Mars or an asteroid. This article concentrates on self-contained structures envisaged for micro-g environments. Definition A space habitat, or more precisely a space settlement, is any large-scale habitation facility in space, or more particularly in outer space or an orbit. A space habitat is typically de ...

Mirror
A mirror or looking glass is an object that Reflection (physics), reflects an image. Light that bounces off a mirror will show an image of whatever is in front of it, when focused through the lens of the eye or a camera. Mirrors reverse the direction of the image in an equal yet opposite angle from which the light shines upon it. This allows the viewer to see themselves or objects behind them, or even objects that are at an angle from them but out of their field of view, such as around a corner. Natural mirrors have existed since prehistoric times, such as the surface of water, but people have been manufacturing mirrors out of a variety of materials for thousands of years, like stone, metals, and glass. In modern mirrors, metals like silver or aluminium are often used due to their high reflectivity, applied as a thin coating on glass because of its naturally smooth and very Hardness (materials science), hard surface. A mirror is a Wave (physics), wave reflector. Light consis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carbon Nanotubes
A scanning tunneling microscopy image of a single-walled carbon nanotube Rotating single-walled zigzag carbon nanotube A carbon nanotube (CNT) is a tube made of carbon with diameters typically measured in nanometers. ''Single-wall carbon nanotubes'' (''SWCNTs'') are one of the allotropes of carbon, intermediate between fullerene cages and flat graphene, with diameters in the range of a nanometre. Although not made this way, single-wall carbon nanotubes can be idealized as cutouts from a two-dimensional Hexagonal tiling, hexagonal lattice of carbon atoms rolled up along one of the Bravais lattice vectors of the hexagonal lattice to form a hollow cylinder. In this construction, periodic boundary conditions are imposed over the length of this roll-up vector to yield a helical lattice of seamlessly bonded carbon atoms on the cylinder surface. ''Multi-wall carbon nanotubes'' (''MWCNTs'') consisting of nested single-wall carbon nanotubes weakly bound together by van der Waals i ...

Rotating Wheel Space Station
A rotating wheel space station, also known as a von Braun wheel, is a concept for a hypothetical wheel-shaped space station. Originally proposed by Konstantin Tsiolkovsky in 1903, the idea was expanded by Herman Potočnik in 1929. Specifications This type of station rotates about its axis, creating an environment of artificial gravity. Occupants of the station would experience centripetal acceleration, according to the following equation: : a = -\omega^2 r where \omega is the angular velocity of the station, r is its radius, and a is linear acceleration at any point along its perimeter. In theory, the station could be configured to simulate the gravitational acceleration of Earth (9.81 m/s2), allowing for human long stays in space without the drawbacks of microgravity. History Both scientists and science fiction writers have thought about the concept of a rotating wheel space station since the beginning of the 20th century. Konstantin Tsiolkovsky wrote about using rotati ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Outer Wilds
''Outer Wilds'' is a 2019 action-adventure game developed by Mobius Digital and published by Annapurna Interactive. It first released for Windows, Xbox One, and PlayStation 4 before releasing for PlayStation 5 and Xbox Series X/S in 2022. A Nintendo Switch version is also under development. The game features the player character exploring a solar system stuck in a 22-minute time loop that ends with the star going supernova. The player progresses through ''Outer Wilds'' by exploring the solar system and learning clues to the cause of the time loop. ''Outer Wilds'' received critical acclaim and several Game of the Year awards, including at the 16th British Academy Games Awards. The game received an expansion, ''Echoes of the Eye'', in 2021. Gameplay ''Outer Wilds'' features an unnamed player character exploring a solar system that is stuck in a time loop, going back 22 minutes before its star goes supernova.

The Culture
The Culture is a fictional interstellar post-scarcity civilisation or society created by the Scottish writer Iain M. Banks and features in a number of his space opera novels and works of short fiction, collectively called the Culture series. In the series, the Culture is composed primarily of sentient beings of the humanoid alien variety, artificially intelligent sentient machines, and a small number of other sentient "alien" life forms. Machine intelligences range from human-equivalent drones to hyper-intelligent Minds. Artificial intelligences with capabilities measured as a fraction of human intelligence also perform a variety of tasks, e.g. controlling spacesuits. Without scarcity, the Culture has no need for money; instead, minds voluntarily indulge humanoid and drone citizens' pleasures, leading to a largely hedonistic society. Many of the series' protagonists are humanoids who choose to work for the Culture's elite diplomatic or espionage organisations, and interact wi ...

Halo Series
''Halo'' is a military science fiction media franchise, originally developed by Bungie and currently managed and developed by 343 Industries, part of Microsoft's Xbox Game Studios. The series launched in 2001 with the first-person shooter video game '' Halo: Combat Evolved'' and its tie-in novel, '' The Fall of Reach''. The latest main game, ''Halo Infinite'', was released in 2021. ''Combat Evolved'' started life as a real-time strategy game, before morphing into a first-person shooter and releasing as an exclusive on Microsoft's new Xbox video game console after Bungie was acquired by the company. Bungie regained its independence in 2007, releasing additional ''Halo'' games through 2010. Microsoft established 343 Industries to direct the franchise going forward, and has produced games itself and in partnership with other studios. ''Combat Evolved'' was a critical and commercial success, serving as the Xbox's "killer app" and cementing Microsoft as a major player in the video ...

Halo Array
The ''Halo'' video game and media franchise takes place in a fictional science fiction universe. In the distant past, a race known as the Forerunners fought the parasitic Flood. The Forerunners ultimately activate weapons of mass destruction, the Halo Array, in order to starve the Flood and stop the threat. By the 26th century, humanity, led by the United Nations Space Command (UNSC), is caught in a war with an alien coalition known as the Covenant. The Covenant worship the Forerunners as deities, mistakenly believing that the Halos are a tool of salvation, not destruction. The Flood, meanwhile, escape the confines of Halo and threaten to spread across the galaxy again. A large portion of the series' success lies in the creation of a believable world, and Bungie reinforced the fictional factions the player interacts with via a lengthy design process with the release of each game. The overall design of each faction was slowly developed before the release of the first game in the s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Worldbuilding
Worldbuilding is the process of constructing a world, originally an imaginary one, sometimes associated with a fictional universe. Developing an imaginary setting with coherent qualities such as a history, geography, and ecology is a key task for many science fiction or fantasy writers. Worldbuilding often involves the creation of geography, a backstory, flora, fauna, inhabitants, technology and often if writing speculative fiction, different races. This may include social customs as well as invented languages for the world. The world could encompass different planets spanning vast distances of space or be limited in scope to a single small village. World building exists in novels, tabletop role-playing games, and visual media such as films, video games and comics. Prior to 1900 most worldbuilding was conducted by novelists, who could leave imagination of the fictional setting in part to the reader. Some authors of fiction set multiple works in the same world. This is known as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Orion's Arm
Orion's Arm (also called the Orion's Arm Universe Project, OAUP, or simply OA and formerly known as the Orion's Arm Worldbuilding Group) is a multi-authored online science fiction world-building project, first established in 2000 by M. Alan Kazlev, Donna Malcolm Hirsekorn, Bernd Helfert and Anders Sandberg and further co-authored by many people since. Anyone can contribute articles, stories, artwork, or music to the website. A large mailing list exists, in which members debate aspects of the world they are creating, discussing additions, modifications, issues arising, and work to be done. A computer game and a tabletop role-playing game are being developed by the community, within the OA milieu. There is an ezine for Orion's Arm fiction, art, and commentary, called ''Voices: Future Tense'', add-ons for the Celestia program to displaying Orion's Arm planets, spacecraft and other objects, and additional transhumanist flavored SF illustrations. The first published Orion's Arm bo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lagrangian Points
In celestial mechanics, the Lagrange points (; also Lagrangian points or libration points) are points of equilibrium for small-mass objects under the influence of two massive orbiting bodies. Mathematically, this involves the solution of the restricted three-body problem in which two bodies are far more massive than the third. Normally, the two massive bodies exert an unbalanced gravitational force at a point, altering the orbit of whatever is at that point. At the Lagrange points, the gravitational forces of the two large bodies and the centrifugal force balance each other. This can make Lagrange points an excellent location for satellites, as few orbit corrections are needed to maintain the desired orbit. Small objects placed in orbit at Lagrange points are in equilibrium in at least two directions relative to the center of mass of the large bodies. For any combination of two orbital bodies there are five Lagrange points, L1 to L5, all in the orbital plane of the two lar ...
