Space Trade
Space trade is interplanetary or interstellar trade. Plans and ideas on how trade functions have been published by Futurists and pundits since the 1960s, though science fiction writers have been envisioning such trade for several more decades. Reality Though the existence of interstellar trade is unknown, there are several theories developed by well known economists such as Paul Krugman on how trade calculations and interest rates would have to be adjusted in such a circumstance. At very high velocities, for example a space station traveling at significant speeds relative to the speed of light, there will be time dilation. In 2004 Espen Gaarder Haug published a technical research article in ''Wilmott Magazine'' on how interest rates and securities calculations had to be adjusted for very high velocities to avoid arbitrage. He published similar theories on what he called "SpaceTime Finance" in a book published in 2007 titled ''Derivatives Models on Models''. Paul Krugman, winner ...

Phobos (moon)
Phobos (; astronomical naming conventions, systematic designation: ) is the innermost and larger of the two moons of Mars, natural satellites of Mars, the other being Deimos (moon), Deimos. The two moons were discovered in 1877 by American astronomer Asaph Hall. It is named after Phobos (mythology), Phobos, the Greek mythology, Greek god of fear and panic, who is the son of Ares (Mars) and twin brother of Deimos (deity), Deimos. Phobos is a small, irregularly shaped object with a mean radius of . Phobos orbits from the Martian surface, closer to its Primary (astronomy), primary body than any other known Natural satellite, planetary moon. It is so close that it orbits Mars much faster than Mars rotates, and completes an orbit in just 7 hours and 39 minutes. As a result, from the surface of Mars it appears to rise in the west, move across the sky in 4 hours and 15 minutes or less, and set in the east, twice each Mars sol, Martian day. Phobos is one of the least reflective bodie ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Space-based Economy
Space-based economy is economic activity in outer space, including asteroid mining, space manufacturing, space trade, construction performed in space such as the building of space stations, space burial, and space advertising. Space-based industrial efforts are presently in their infancy. Most such concepts would require a considerable long-term human presence in space and relatively low-cost access to space. The majority of proposals would also require technological or engineering developments in areas such as robotics, solar energy, and life support systems. Some analysts have argued for creating an International Bank, to support deep space exploration.

Cato Institute
The Cato Institute is an American libertarian think tank headquartered in Washington, D.C. It was founded in 1977 by Ed Crane, Murray Rothbard, and Charles Koch, chairman of the board and chief executive officer of Koch Industries.Koch Industries is the second largest privately held company by revenue in the United States. Cato was established to have a focus on public advocacy, media exposure and societal influence. According to the ''2020 Global Go To Think Tank Index Report'' (Think Tanks and Civil Societies Program, University of Pennsylvania), Cato is number 27 in the "Top Think Tanks Worldwide" and number 13 in the "Top Think Tanks in the United States". The Cato Institute is libertarian in its political philosophy, and advocates a limited role for government in domestic and foreign affairs as well as a strong protection of civil liberties. This includes support for lowering or abolishing most taxes, opposition to the Federal Reserve system and the Affordable Care Act, ...

International Institute Of Space Commerce
The International Institute of Space Commerce (IISC) was established at the Isle of Man in 2007 as a corporation between the International Space University (ISU) and the Government of the Isle of Man. Realizing that the new space economy is being confronted with new challenges, it was felt necessary to establish a new think-tank focusing on commercial space aspects in addition to other space think-tanks, most of them with an emphasis on governmental space activities. The location on the Isle of Man was targeted towards the growth of commercial space economy attracted on the Isle by creating a favorable environment for commercial space companies. The think-tank activity has been established and is intended to provide an added value to the services offered locally. History The idea of IISC originated in 2007 based upon an agreement between both entities. In 2008, IISC was established as a non-profit organization with offices in Douglas, at the Isle of Man International Busines ...

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 ...

Space-based Solar Power
Space-based solar power (SBSP, SSP) is the concept of collecting solar power in outer space by solar power satellites (SPS) and distributing it to Earth. Its advantages include a higher collection of energy due to the lack of reflection and absorption by the atmosphere, the possibility of no (or very little) night, and a better ability to orient to face the sun. Space-based solar power systems convert sunlight to some other form of energy (such as microwaves) which can be transmitted through the atmosphere to receivers on the Earth's surface. It is attractive to those seeking large-scale solutions to anthropogenic climate change or fossil fuel depletion (such as peak oil). Various SBSP proposals have been researched since the early 1970s, but none is economically viable with present-day space launch costs. Some technologists speculate that this may change in the distant future with space manufacturing from asteroids or lunar material, or with radical new space launch techno ...

Helium-3
Helium-3 (3He see also helion) is a light, stable isotope of helium with two protons and one neutron (the most common isotope, helium-4, having two protons and two neutrons in contrast). Other than protium (ordinary hydrogen), helium-3 is the only stable isotope of any element with more protons than neutrons. Helium-3 was discovered in 1939. Helium-3 occurs as a primordial nuclide, escaping from Earth's crust into its atmosphere and into outer space over millions of years. Helium-3 is also thought to be a natural nucleogenic and cosmogenic nuclide, one produced when lithium is bombarded by natural neutrons, which can be released by spontaneous fission and by nuclear reactions with cosmic rays. Some of the helium-3 found in the terrestrial atmosphere is also an artifact of atmospheric and underwater nuclear weapons testing. Much speculation has been made over the possibility of helium-3 as a future energy source. Unlike most nuclear fusion reactions, the fusion of helium-3 ...

NASA
The National Aeronautics and Space Administration (NASA ) is an independent agency of the US federal government responsible for the civil space program, aeronautics research, and space research. NASA was established in 1958, succeeding the National Advisory Committee for Aeronautics (NACA), to give the U.S. space development effort a distinctly civilian orientation, emphasizing peaceful applications in space science. NASA has since led most American space exploration, including Project Mercury, Project Gemini, the 1968-1972 Apollo Moon landing missions, the Skylab space station, and the Space Shuttle. NASA supports the International Space Station and oversees the development of the Orion spacecraft and the Space Launch System for the crewed lunar Artemis program, Commercial Crew spacecraft, and the planned Lunar Gateway space station. The agency is also responsible for the Launch Services Program, which provides oversight of launch operations and countdown management f ...

Asteroid
An asteroid is a minor planet of the inner Solar System. Sizes and shapes of asteroids vary significantly, ranging from 1-meter rocks to a dwarf planet almost 1000 km in diameter; they are rocky, metallic or icy bodies with no atmosphere. Of the roughly one million known asteroids the greatest number are located between the orbits of Mars and Jupiter, approximately 2 to 4 AU from the Sun, in the main asteroid belt. Asteroids are generally classified to be of three types: C-type, M-type, and S-type. These were named after and are generally identified with carbonaceous, metallic, and silicaceous compositions, respectively. The size of asteroids varies greatly; the largest, Ceres, is almost across and qualifies as a dwarf planet. The total mass of all the asteroids combined is only 3% that of Earth's Moon. The majority of main belt asteroids follow slightly elliptical, stable orbits, revolving in the same direction as the Earth and taking from three to six years to comple ...

Natural Satellite
A natural satellite is, in the most common usage, an astronomical body that orbits a planet, dwarf planet, or small Solar System body (or sometimes another natural satellite). Natural satellites are often colloquially referred to as ''moons'', a derivation from the Moon of Earth. In the Solar System, there are six planetary satellite systems containing 209 known natural satellites altogether. Seven objects commonly considered dwarf planets by astronomers are also known to have natural satellites: , Pluto, Haumea, , Makemake, , and Eris. , there are 442 other minor planets known to have natural satellites. A planet usually has at least around 10,000 times the mass of any natural satellites that orbit it, with a correspondingly much larger diameter. The Earth–Moon system is a unique exception in the Solar System; at 3,474 kilometres (2,158 miles) across, the Moon is 0.273 times the diameter of Earth and about of its mass. The next largest ratios are the Neptune–Tr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
