Cockburn Island (Polynesia)
Fangataufa (or Fangatafoa) is an uninhabited coral atoll in the eastern part of the Tuamotu Archipelago in French Polynesia. The atoll has been fully-owned by the French state since 1964. From 1966 to 1996 it was used as a nuclear test site by the French government. In total, 4 atmospheric and 10 underground nuclear explosions were carried out on the atoll. Geography The atoll is a coral outgrowth of a seamount which rises some from the seafloor, to a depth of . The seamount was formed 33.4 - 34.7 million years ago by the Pitcairn hotspot. The island is approx. long and wide. It has a lagoon area of and a land area of . It is located south of Moruroa atoll, east of Tematangi, southwest of the Gambier Islands and southeast of Tahiti. Access to the lagoon is through a pass lying SW of the northernmost point of the atoll; the channel has a width of about and a dredged depth of . A quay, in of water, is situated in the NE part of the lagoon; another quay, long in of w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Vanavana
Vanavana, Kurataki, or Huataki is an atoll in the southeastern area of the Tuamotu Archipelago, French Polynesia. Vanavana's nearest neighbour is Tureia, which is located to the east. Vanavana is a small oval-shaped atoll. It measures approximately in length, has a maximum width of and a land area of approximately . Its reef encloses completely the deep lagoon, which is . There is one hook-shaped large island in the north and another in the south of its reef. Vanavana Atoll is uninhabited; however, buildings on the northern end of the island are present. History The first recorded European to arrive at Vanavana was British mariner Captain Frederick Beechey in 1826. He named this atoll "Barrow Island", after Sir John Barrow. Administration Administratively Vanavana Atoll belongs to the commune of Tureia, which includes the atolls of Tureia, Fangataufa, Moruroa, Tematangi Tematagi or TematangiBoard of Geographical Names Site Internet: http://geonames.usgs.gov/foreign/index ...

Commune Of France
The () is a level of administrative division in the French Republic. French are analogous to civil townships and incorporated municipalities in the United States and Canada, ' in Germany, ' in Italy, or ' in Spain. The United Kingdom's equivalent are civil parishes, although some areas, particularly urban areas, are unparished. are based on historical geographic communities or villages and are vested with significant powers to manage the populations and land of the geographic area covered. The are the fourth-level administrative divisions of France. vary widely in size and area, from large sprawling cities with millions of inhabitants like Paris, to small hamlets with only a handful of inhabitants. typically are based on pre-existing villages and facilitate local governance. All have names, but not all named geographic areas or groups of people residing together are ( or ), the difference residing in the lack of administrative powers. Except for the municipal arrondi ...

French Alternative Energies And Atomic Energy Commission
The French Alternative Energies and Atomic Energy Commission or CEA ( French: Commissariat à l'énergie atomique et aux énergies alternatives), is a French public government-funded research organisation in the areas of energy, defense and security, information technologies and health technologies. The CEA maintains a cross-disciplinary culture of engineers and researchers, building on the synergies between fundamental and technological research. CEA is headed by a board headed by the general administrator (currently François Jacq since 20 April 2018), advised by the high-commissioner for atomic energy (currently Patrick Landais). Its yearly budget amounts to €5.1 billion and its permanent staff is slightly over 20,500 persons. It owned Areva. CEA was created in 1945; since then, the successive high-commissioners have been Frédéric Joliot-Curie, Francis Perrin, Jacques Yvon, Jean Teillac, Raoul Dautry, René Pellat, Bernard Bigot, Daniel Verwaerde and François Jacq.

Thermonuclear
Thermonuclear fusion is the process of atomic nuclei combining or “fusing” using high temperatures to drive them close enough together for this to become possible. There are two forms of thermonuclear fusion: ''uncontrolled'', in which the resulting energy is released in an uncontrolled manner, as it is in thermonuclear weapons ("hydrogen bombs") and in most stars; and ''controlled'', where the fusion reactions take place in an environment allowing some or all of the energy released to be harnessed for constructive purposes. Temperature requirements Temperature is a measure of the average kinetic energy of particles, so by heating the material it will gain energy. After reaching sufficient temperature, given by the Lawson criterion, the energy of accidental collisions within the plasma is high enough to overcome the Coulomb barrier and the particles may fuse together. In a deuterium–tritium fusion reaction, for example, the energy necessary to overcome the Coulomb barrier ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nuclear Weapon Design
Nuclear weapon designs are physical, chemical, and engineering arrangements that cause the physics package of a nuclear weapon to detonate. There are three existing basic design types: * pure fission weapons, the simplest and least technically demanding, were the first nuclear weapons built and have so far been the only type ever used in warfare (by the United States on Empire of Japan, Japan during World War II, WWII). * boosted fission weapons increase yield beyond that of the implosion design by using small quantities of fusion fuel to enhance the fission chain reaction. Boosting can more than double the weapon's fission energy yield. * thermonuclear weapon, staged thermonuclear weapons are essentially arrangements of two or more "stages", most usually two. The first stage is normally a boosted fission weapon as above (except for the earliest thermonuclear weapons, which used a pure fission weapon instead). Its detonation causes it to shine intensely with x-radiation, which ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Canopus (nuclear Test)
''Canopus'' (or ''Opération Canopus'') was the codename of the first French two-stage thermonuclear test. It was conducted by the Pacific Carrier Battle Group (nicknamed ''Alfa Force'') on 24 August 1968, at the Pacific Experiments Centre near Fangataufa atoll, French Polynesia. The test made France the fifth country to test a thermonuclear device after the United States, the Soviet Union, the United Kingdom and China. History In 1966, France was able to use fusion fuel to boost plutonium implosion devices with the Rigel shot. Robert Dautray, (real name : Ignatz Koushelewitz) a nuclear physicist, was selected by the CEA to lead the development effort to construct a two-stage weapon. France did not have the ability to produce the materials needed for a two-stage thermonuclear device at the time, so 151 tons of heavy water was purchased from Norway and an additional 168 tons from the United States. This heavy water went into nuclear reactors in 1967 to produce tritium need ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Assembly Of French Polynesia
The Assembly of French Polynesia (french: Assemblée de la Polynésie française, Tahitian: Te apo'ora'a rahi o te fenua Mā'ohi) is the unicameral legislature of French Polynesia, an overseas country of the French Republic. It is located at Place Tarahoi in Pape'ete, Tahiti. It was established in its current form in 1996 although a Tahitian Assembly was first created in 1824. It consists of 57 members who are elected by popular vote for five years; the electoral system is based upon proportional representation in six multi-seat constituencies. Every constituency is represented by at least three representatives. Since 2001, the parity bill binds that the number of women matches the number of men elected to the Assembly. The official language of the Assembly is French. The most recent election was held in 2018 and resulted in a victory of the Tapura Huiraatira, which won 38 seats.
