Astérix (satellite)
''Astérix'' or A-1 (initially conceptualized as FR.2 or FR-2) is the first French satellite. It was launched on 26 November 1965 by a Diamant A rocket from the CIEES launch site at Hammaguir, Algeria. With ''Astérix'', France became the sixth country to have an artificial satellite and the third country to launch a satellite on its own rocket. Its main purpose was to test the Diamant launcher, though it was also designed to study the ionosphere. ''Astérix'' continues to orbit Earth as of 2023 and is expected to remain in orbit for centuries. Background The French space agencies Centre national d'études spatiales (CNES) and Centre national d'études des télécommunications (CNET) were developing ''Astérix'' concurrent with FR-1, another satellite, as early as 1963. FR-1 was the first step of an ambitious French plan to launch six FR-series satellites, each meant to study a different aspect of the Earth's atmosphere. FR-1 was generally designed to study the Earth's magnet ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sun Sensor
A Sun sensor is a navigational instrument used by spacecraft to detect the position of the Sun. Sun sensors are used for Spacecraft attitude control, attitude control, solar array pointing, gyroscope, gyro updating, and safe mode (spacecraft), fail-safe recovery. In addition to spacecraft, Sun sensors find use in ground-based weather stations and Sun-tracking systems, and aerial vehicles including Balloon (aeronautics), balloons and Unmanned aerial vehicle, UAVs. Mechanism There are various types of Sun sensors, which differ in their technology and performance characteristics. Sun presence sensors provide a binary number, binary output, indicating when the Sun is within the sensor's field of view. Analog electronics, Analog and digital electronics, digital Sun sensors, in contrast, indicate the angle of the Sun by continuous and discrete signal outputs, respectively. In typical Sun sensors, a thin slit at the top of a rectangular chamber allows a line of light to fall on an array ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fiberglass
Fiberglass (American English) or fibreglass (English in the Commonwealth of Nations, Commonwealth English) is a common type of fibre-reinforced plastic, fiber-reinforced plastic using glass fiber. The fibers may be randomly arranged, flattened into a sheet called a chopped strand mat, or woven into glass cloth. The plastic Matrix (composite), matrix may be a thermoset polymer matrix—most often based on thermosetting polymers such as epoxy, polyester resin, or vinyl ester resin—or a thermoplastic. Cheaper and more flexible than Carbon-fiber-reinforced polymers, carbon fiber, it is stronger than many metals by weight, non-magnetic, non-conductive, transparent to electromagnetic radiation, can be molded into complex shapes, and is chemically inert under many circumstances. Applications include aircraft, boats, automobiles, bath tubs and enclosures, swimming pools, hot tubs, septic tanks, water tanks, roofing, pipes, cladding, orthopedic casts, surfboards, and external door skins ...

European Space Research Organisation
The European Space Research Organisation (ESRO) was an international organisation founded by 10 European nations with the intention of jointly pursuing scientific research in space. It was founded in 1964. As an organisation ESRO was based on a previously existing international scientific institution, CERN. The ESRO convention, the organisations founding document outlines it as an entity exclusively devoted to scientific pursuits. This was the case for most of its lifetime but in the final years before the formation of ESA, the European Space Agency, ESRO began a programme in the field of telecommunications. Consequently, ESA is not a mainly pure science focused entity but concentrates on telecommunications, earth observation and other application motivated activities. ESRO was merged with European Launcher Development Organisation, ELDO in 1975 to form the European Space Agency. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Intermediate-range Ballistic Missile
An intermediate-range ballistic missile (IRBM) is a ballistic missile with a range (aeronautics), range between (), categorized between a medium-range ballistic missile (MRBM) and an intercontinental ballistic missile (ICBM). Classifying ballistic missiles by range is done mostly for convenience. In principle there is little difference between a high-performance IRBM and a low-performance ICBM, because decreasing payload mass can increase the range over the ICBM threshold. The range definition used here is used within the U.S. Missile Defense Agency. History The progenitor for the IRBM was the Aggregate (rocket family)#A4b/A9, A4b rocket, winged for increased range and based on the famous V-2 rocket, V-2, Vergeltung, or "Reprisal", officially called Aggregate series, A4, rocket designed by Wernher von Braun. The V-2 was widely used by Nazi Germany at the end of World War II to bomb English and Belgian cities. The A4b was the prototype for the upper stage of the Aggregate (rock ...

V-2 Rocket
The V2 (), with the technical name ''Aggregat (rocket family), Aggregat-4'' (A4), was the world's first long-range missile guidance, guided ballistic missile. The missile, powered by a liquid-propellant rocket engine, was developed during the Second World War in Nazi Germany as a "V-weapons, vengeance weapon" and assigned to attack Allies of World War II, Allied cities as retaliation for the Strategic bombing during World War II#The British later in the war, Allied bombings of German cities. The rocket also became the first artificial object to travel into space by crossing the Kármán line (edge of space) with the vertical launch of MW 18014 on 20 June 1944. Research of military use of long-range rockets began when the graduate studies of Wernher von Braun were noticed by the German Army. A series of prototypes culminated in the A4, which went to war as the . Beginning in September 1944, more than 3,000 were launched by the Wehrmacht against Allied targets, first London and ...

Gaullism
Gaullism ( ) is a Politics of France, French political stance based on the thought and action of World War II French Resistance leader Charles de Gaulle, who would become the founding President of France, President of the Fifth French Republic. De Gaulle French withdrawal from NATO command, withdrew French forces from the Structure of NATO, NATO Command Structure, forced the removal of allied (United States, US) military bases from France, as well as initiated Force de dissuasion, France's own independent nuclear deterrent programme. His actions were predicated on the view that France would not be subordinate to other nations. According to Serge Berstein, Gaullism is "neither a doctrine nor a political ideology" and cannot be considered either Left-wing politics, left or Right-wing politics, right. Rather, "considering its historical progression, it is a Pragmatism, pragmatic exercise of power that is neither free from contradictions nor of concessions to momentary necessity, eve ...
