Ariane 1
Ariane 1 was the first rocket in the Ariane family of expendable launch systems. It was developed and operated by the European Space Agency (ESA), which had been formed in 1973, the same year that development of the launcher had commenced. Ariane 1 was the first launcher to be developed with the primary purpose of sending commercial satellites into geosynchronous orbit. Crucially, it was designed with the ability of sending a pair of satellites into orbit on a single launcher, thus reducing costs. As the size of satellites grew, Ariane 1 quickly gave way to the more powerful Ariane 2 and Ariane 3 launchers, which were heavily based upon the original rocket. The Ariane 4 was the last rocket to heavily draw upon the Ariane 1, as the successor rocket Ariane 5 uses a far greater proportion of all-new elements. Development Origins In 1975, eleven European countries decided to pursue joint collaboration in the field of space exploration and formed a new pan-national organisation ...

Ariane 2
Ariane 2 was a European expendable space launch vehicle, operated by the European Space Agency (ESA) between 1986 and 1989 as part of Ariane family of rockets. The principal manufacturer for the Ariane 2 was Aérospatiale, while the lead agency for its development was the ''Centre National d'Etudes Spatiales'' (CNES), the French government's space agency.Harvey 2003, p. 515. Development of the Ariane 2 was authorised in July 1979, months prior to the Ariane 1's first flight. Drawing heavily upon both the design and infrastructure of the Ariane 1, the new launcher was concurrently developed alongside the Ariane 3, with which it shared much of its design. It represented an advancement of the Ariane 1 rather than a replacement, but was capable of lifting even heavier payloads into Geostationary transfer orbit (GTO). Developed largely within a two-year window, the Ariane 2 performed its maiden flight on 31 May 1986, actually flying after its Ariane 3 sibling. During its brief servic ...

Ariane 3
Ariane 3 was a European expendable carrier rocket, which was used for eleven launches between 1984 and 1989. It was a member of the Ariane family of rockets. The principal manufacturer for the Ariane 3 was Aérospatiale, while the lead agency for its development was the Centre National d'Etudes Spatiales (CNES). Development of the Ariane 3 was authorised in July 1979, months prior to the Ariane 1's first flight. Drawing heavily upon both the design and infrastructure of the Ariane 1, the new launcher was concurrently developed alongside the Ariane 2, with which it shared much of its design. It represented an advancement of the Ariane 1 rather than a replacement, but was capable of lifting even heavier payloads into Geostationary transfer orbit (GTO) as well as launching two satellites via one launch. Developed largely within a two year window, the Ariane 3 performed its maiden flight on 4 August 1984, actually flying in advance of its Ariane 2 sibling. During its brief service l ...

Geosynchronous Orbit
A geosynchronous orbit (sometimes abbreviated GSO) is an Earth-centered orbit with an orbital period that matches Earth's rotation on its axis, 23 hours, 56 minutes, and 4 seconds (one sidereal day). The synchronization of rotation and orbital period means that, for an observer on Earth's surface, an object in geosynchronous orbit returns to exactly the same position in the sky after a period of one sidereal day. Over the course of a day, the object's position in the sky may remain still or trace out a path, typically in a figure-8 form, whose precise characteristics depend on the orbit's inclination and eccentricity. A circular geosynchronous orbit has a constant altitude of . A special case of geosynchronous orbit is the geostationary orbit, which is a circular geosynchronous orbit in Earth's equatorial plane with both inclination and eccentricity equal to 0. A satellite in a geostationary orbit remains in the same position in the sky to observers on the surface. Communicat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aerospace Manufacturer
An aerospace manufacturer is a company or individual involved in the various aspects of designing, building, testing, selling, and maintaining aircraft, aircraft parts, missiles, rockets, or spacecraft. Aerospace is a high technology industry. The aircraft industry is the industry supporting aviation by building aircraft and manufacturing aircraft parts for their maintenance. This includes aircraft and parts used for civil aviation and military aviation. Most production is done pursuant to type certificates and Defense Standards issued by a government body. This term has been largely subsumed by the more encompassing term: "aerospace industry". Market In 2015 the aircraft production was worth US$180.3 Billion: 61% airliners, 14% business and general aviation, 12% Military aircraft, 10% military rotary wing and 3% civil rotary wing; while their MRO was worth $135.1 Bn or $ Bn combined. The global aerospace industry was worth $838 billion in 2017: Aircraft & Engine OEMs rep ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ballistic Missile
A ballistic missile is a type of missile that uses projectile motion to deliver warheads on a target. These weapons are guided only during relatively brief periods—most of the flight is unpowered. Short-range ballistic missiles stay within the Earth's atmosphere, while intercontinental ballistic missiles (ICBMs) are launched on a sub-orbital flight. These weapons are in a distinct category from cruise missiles, which are aerodynamically guided in powered flight. Unlike cruise missiles, which are restricted to the atmosphere, it is advantageous for ballistic missiles to avoid the denser parts of the atmosphere and they may travel above the atmosphere into outer space. History The earliest form of ballistic missile dates from the 13th century with its use derived from the history of rockets. In the 14th century, the Ming Chinese navy used an early form of a ballistic missile weapon called the Huolongchushui in naval battles against enemy ships.Needham, Volume 5, Part 7, ...

Georges Pompidou
Georges Jean Raymond Pompidou ( , ; 5 July 19112 April 1974) was a French politician who served as President of France from 1969 until his death in 1974. He previously was Prime Minister of France of President Charles de Gaulle from 1962 to 1968—the longest tenure in the position's history. In the context of the strong growth of the last years of the ''Trente Glorieuses'', Pompidou continued De Gaulle's policy of modernisation, symbolised by the presidential use of the Concorde, the creation of large industrial groups and the launch of the high-speed train project (TGV). The State invested heavily in the automobile, agri-food, steel, telecommunications, nuclear and aerospace sectors. It also created the minimum wage (SMIC) and the Ministry of the Environment. His foreign policy, pragmatic although in keeping with the Gaullist principle of French independence, was marked by a warming of relations with Nixon's United States, as well as by close relations with Brezhnev's USSR, ...

Willy Brandt
Willy Brandt (; born Herbert Ernst Karl Frahm; 18 December 1913 – 8 October 1992) was a German politician and statesman who was leader of the Social Democratic Party of Germany (SPD) from 1964 to 1987 and served as the chancellor of West Germany from 1969 to 1974. He was awarded the Nobel Peace Prize in 1971 for his efforts to strengthen cooperation in western Europe through the EEC and to achieve reconciliation between West Germany and the countries of Eastern Europe. He was the first Social Democrat chancellor since 1930. Fleeing to Norway and then Sweden during the Nazi regime and working as a left-wing journalist, he took the name Willy Brandt as a pseudonym to avoid detection by Nazi agents, and then formally adopted the name in 1948. Brandt was originally considered one of the leaders of the right wing of the SPD, and earned initial fame as Governing Mayor of West Berlin. He served as the foreign minister and as the vice-chancellor in Kurt Georg Kiesinger's cabi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Europa (rocket)
The Europa rocket was an early expendable launch system of the European Launcher Development Organisation (ELDO), which was the precursor to the European Space Agency (ESA). It was developed with the aim to delivering space access technology, and more specifically to facilitate the deployment of European-wide telecommunication and meteorological satellites into orbit. The program ultimately traces its history to the British Blue Streak missile, which was cancelled in 1960. Blue Streak was then used as the basis of the Black Prince expendable launch system and several other concepts. Looking for partners to share development costs, ELDO was formed and began development of the Europa using the Blue Streak first stage along with the French-built Coralie second stage and German Astris upper stage. The programme proceeded to perform multiple test launches but these frequently resulted in partial failures. In addition, Britain decided to pull out of the ELDO organisation, and thus E ...
