Colonization Of Mercury
Space colonization (also called space settlement or extraterrestrial colonization) is the use of outer space or celestial bodies other than Earth for permanent habitation or as extraterrestrial territory. The inhabitation and territorial use of extraterrestrial space has been proposed to be realized by for example building space settlements or extraterrestrial mining enterprises. To date, no permanent space settlement other than temporary space habitats have been set up, nor any extraterrestrial territory or land has been legally claimed. Making territorial claims in space is prohibited by international space law, defining space as a common heritage. International space law has had the goal to prevent colonial claims and militarization of space, advocating the installation of international regimes to regulate access to and sharing of space, particularly for specific locations such as the limited space of geostationary orbit or the Moon. Many arguments both for and a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Commodification
Within a capitalist economic system, commodification is the transformation of things such as goods, services, ideas, nature, personal information, people or animals into objects of trade or commodities.For animals"United Nations Commodity Trade Statistics Database" UN ComTrade; Josephine Donovan, "Aestheticizing Animal Cruelty," ''College Literature'', 38(4), Fall 2011 (pp. 202–217), p. 203. For slaves as commodities, Appadurai 1986, pp. 84–85; David Hawkes, ''Shakespeare and Economic Theory'', Bloomsbury Publishing, 2015, p. 130. For body commodification, Lesley A. Sharp, "The Commodification of the Body and Its Parts," ''Annual Review of Anthropology'', 29, 2000 (pp. 287–328) p. 295ff. A commodity at its most basic, according to Arjun Appadurai, is "anything intended for exchange," or any object of economic value. Commodification is often criticized on the grounds that some things ought not to be treated as commodities—for example, water, education, data, informati ...

Research Station
Research stations are facilities where scientific investigation, collection, analysis and experimentation occurs. A research station is a facility that is built for the purpose of conducting scientific research. There are also many types of research stations including: biological field stations, space stations etc. Research station sites might include remote areas of the world, oceans, as well as outer space, such as the International Space Station. Biological research stations developed during a time of European colonization and imperialism where naturalists were employed to conduct observations on fauna and flora. Today, the discipline is represented by a number of organizations which span across multiple continents. Some examples include: the Organization of Biological Field Stations and the Organization for Tropical Studies. Space stations were also developed over a number of decades through scientific analysis and writing, with the first design aspects of early space stat ...

Space Habitat (facility)
Space is the boundless three-dimensional extent in which objects and events have relative position and direction. In classical physics, physical space is often conceived in three linear dimensions, although modern physicists usually consider it, with time, to be part of a boundless four-dimensional continuum known as spacetime. The concept of space is considered to be of fundamental importance to an understanding of the physical universe. However, disagreement continues between philosophers over whether it is itself an entity, a relationship between entities, or part of a conceptual framework. Debates concerning the nature, essence and the mode of existence of space date back to antiquity; namely, to treatises like the '' Timaeus'' of Plato, or Socrates in his reflections on what the Greeks called ''khôra'' (i.e. "space"), or in the ''Physics'' of Aristotle (Book IV, Delta) in the definition of ''topos'' (i.e. place), or in the later "geometrical conception of place" as "s ...

Freeman Dyson
Freeman John Dyson (15 December 1923 – 28 February 2020) was an English-American theoretical physicist and mathematician known for his works in quantum field theory, astrophysics, random matrices, mathematical formulation of quantum mechanics, condensed matter physics, nuclear physics, and engineering. He was Professor Emeritus in the Institute for Advanced Study in Princeton and a member of the Board of Sponsors of the Bulletin of the Atomic Scientists. Dyson originated several concepts that bear his name, such as Dyson's transform, a fundamental technique in additive number theory, which he developed as part of his proof of Mann's theorem; the Dyson tree, a hypothetical genetically engineered plant capable of growing in a comet; the Dyson series, a perturbative series where each term is represented by Feynman diagrams; the Dyson sphere, a thought experiment that attempts to explain how a spacefaring, space-faring civilization would meet its energy requirements with ...

Space Advocacy
Space advocacy is supporting or advocating for a human use of outer space. Purposes advocated can reach from space exploration, or commercial use of space to even space settlement. There are many different individuals and organizations dedicated to space advocacy. They are usually active in educating the public on space related subjects, lobbying governments for increased funding in space-related activities or supporting private space activities. They also recruit members, fund projects, and provide information for their membership and interested visitors. They are sub-divided into three categories depending on their primary work: practice, advocacy, and theory. History The idea that space flight was possible and necessary was introduced by groups of thinkers, primarily members of the Russian, American, British, and German science communities, who formed in the 1920s the first advocacy groups. Starting in the 1930s, these groups began to share their individual plans for a fu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Space Manufacturing
Space manufacturing is the production of tangible goods beyond Earth. Since most production capabilities are limited to low Earth orbit, the term in-orbit manufacturing is also frequently used. There are several rationales supporting in-space manufacturing: * The space environment, in particular the effects of microgravity and vacuum, enable the research of and production of goods that could otherwise not be manufactured on Earth. * The extraction and processing of raw materials from other astronomical bodies, also called In-Situ Resource Utilisation (ISRU) could enable more sustainable space exploration missions at reduced cost compared to launching all required resources from Earth. * Raw materials could be transported to low Earth orbit where they could be processed into goods that are shipped to Earth. By replacing terrestrial production on Earth, this seeks to preserve the Earth. * Raw materials of very high value, for example gold, silver, or platinum, could be transpo ...

Reusable Launch System
A reusable launch vehicle have parts that can be recovered and reflown, while carrying payloads from the surface to outer space. Rocket stages are the most common launch vehicle parts aimed for reuse. Smaller parts such as rocket engines and boosters can also be reused, though reusable spacecraft may be launched on top of an expendable launch vehicle. Reusable launch vehicles do not need to make these parts for each launch, therefore reducing its launch cost significantly. However, these benefits are diminished by the cost of recovery and refurbishment. Reusable launch vehicles may contain additional avionics and propellant, making them heavier than their expendable counterparts. Reused parts may need to enter the atmosphere and navigate through it, so they are often equipped with heat shields, grid fins, and other flight control surfaces. By modifying their shape, spaceplanes can leverage aviation mechanics to aid in its recovery, such as gliding or lift. In the atmosphere, par ...

Falcon Heavy
Falcon Heavy is a partially reusable heavy-lift launch vehicle that is produced by SpaceX, an American aerospace manufacturer. The rocket consists of two strap-on boosters made from Falcon 9 first stages, a center core also made from a Falcon 9 first stage, and a second stage on top. Falcon Heavy has the second highest payload capacity of any currently operational launch vehicle behind NASA's Space Launch System and the fourth-highest capacity of any rocket to reach orbit, trailing the Saturn V, Energia and Space Launch System. SpaceX conducted Falcon Heavy's maiden launch on 6 February 2018, at 20:45 UTC. The rocket carried Elon Musk's Tesla Roadster belonging to SpaceX founder Elon Musk, with a dummy dubbed "Starman" in the driver's seat, as a dummy payload. The second Falcon Heavy launch occurred on 11 April 2019, and all three booster rockets successfully returned to Earth. The third Falcon Heavy launch successfully occurred on 25 June 2019. Since then, Falcon Heavy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Controlled Ecological Life-support System
Controlled (or closed) ecological life-support systems (acronym CELSS) are a self-supporting life support system for space stations and colonies typically through controlled closed ecological systems, such as the BioHome, BIOS-3, Biosphere 2, Mars Desert Research Station, and Yuegong-1. Original concept CELSS was first pioneered by the Soviet Union during the famed "Space Race" in the 1950s–60s. Originated by Konstantin Tsiolkovsky and furthered by V.I. Vernadsky, the first forays into this science were the use of closed, unmanned ecosystems, expanding into the research facility known as the BIOS-3. Then in 1965, manned experiments began in the BIOS-3. Rationale Human presence in space, thus far, has been limited to our own Earth–Moon system. Also, everything that astronauts would need in the way of life support (air, water, and food) has been brought with them. This may be economical for short missions of spacecraft, but it is not the most viable solution when dealing w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Effect Of Spaceflight On The Human Body
Venturing into the environment of space can have negative effects on the human body. Significant adverse effects of long-term weightlessness include muscle atrophy and deterioration of the skeleton (spaceflight osteopenia). Other significant effects include a slowing of cardiovascular system functions, decreased production of red blood cells (space anemia), balance disorders, eyesight disorders and changes in the immune system. Additional symptoms include fluid redistribution (causing the " moon-face" appearance typical in pictures of astronauts experiencing weightlessness), loss of body mass, nasal congestion, sleep disturbance, and excess flatulence. Overall, NASA refers to the various deleterious effects of spaceflight on the human body by the acronym RIDGE (i.e., "space radiation, isolation and confinement, distance from Earth, gravity fields, and hostile and closed environments"). The engineering problems associated with leaving Earth and developing space propulsion s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Monthly Review
The ''Monthly Review'', established in 1949, is an independent socialist magazine published monthly in New York City. The publication is the longest continuously published socialist magazine in the United States. History Establishment Following the failure of the independent 1948 Presidential campaign of Henry A. Wallace, two former supporters of the Wallace effort met at the farm in New Hampshire where one of them was living. The two men were literary scholar and Christian socialist F.O. "Matty" Matthiessen and Marxist economist Paul Sweezy, who were former colleagues at Harvard University. Matthiessen came into an inheritance after his father died in an automobile accident in California and had no pressing need for the money. Matthiessen made the offer to Sweezy to underwrite "that magazine weezyand Leo Huberman were always talking about," committing the sum of $5,000 per year for three years. Matthiessen's funds made the launch of ''Monthly Review'' possible, although the a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
