The Brazilian space program refers to the rocketry and space exploration programs conducted by Brazil from 1961 until the creation of the Brazilian Space Agency in 1994. It had significant capabilities in launch vehicles, launch sites, and satellite manufacturing. It was based at the National Institute for Space Research (INPE), under the Ministry of Science and Technology (MCT). The program was under military control, which hindered its development, as other countries (such as the United States) blocked technological development due to concerns over nuclear proliferation. In 1994, the space program was transferred to civilian control under the Brazilian Space Agency. ==History== In an attempt to build a Satellite Launch Vehicle (''Veículo Lançador de Satélite--VLS''), Brazil has since 1964 developed a series of sounding (research) rockets, named Sonda I, II, III, and IV. The early Sondas were test-launched from Barreira do Inferno Launch Center, near the city of Natal in the Northeast Region. The Sonda IV rocket was tested successfully on April 28, 1989. Subsequent launches were made from the Alcântara Launch Center (''Centro de Lançamento de Alcântara--CLA''), in Maranhão, President José Sarney's home state. The CLA, officially dedicated on February 21, 1990, cost more than US$470 million to develop. It is the closest launch center to the equator in the world (2.3 degrees south of the equator), making it attractive for launches of geostationary satellites. For example, because it is so close to the equator it provides a 25 percent fuel savings compared with Kennedy Space Center. On February 9, 1993, the first satellite developed entirely in Brazil, the Data-Collecting Satellite (Satélite de Coleta de Dados—SCD-1), was launched. The SCD-1, sometimes referred to as the "green" satellite, is used by Brazilian National Institute for Space Research (''INPE - Instituto Nacional de Pesquisas Espaciais'') agencies. Both the SCD-1 The SCD-2, which was launched October 22, 1998, by a Pegasus rocket (a U.S. rocket), to collect environmental data. On July 6, 1988, Brazil signed an agreement with China that calls for the joint development (between the INPE and the Chinese Space Agency) of two earth-imaging satellites to be launched by a Long March Chinese rocket from the Shanxi Launching site. Known as the China-Brazil Earth Resources Satellite program (''Satélite Sino-Brasileiro de Recursos Terrestres--CBERS''), the high-resolution CBERS will collect data from the entire planet and will be used for agriculture, geology, hydrology, and the environment. The Sino-Brazilian agreement was inactive from 1988 through 1991 because of Brazil's lack of funds. In October 1991 and November 1994, Brazil and China signed additional agreements for the construction of the satellites, worth US$150 million. The CBERS-1 was scheduled to be launched in May 1997. Embratel, a formerly state-controlled communications company in charge of the Brazilian Satellite Communication System (''Sistema Brasileiro de Comunicação por Satélites--SBTS''), owns and operates a series of satellites that are positioned in geostationary orbit over the equator. Arianespace, a French space and defense partner of France's Aérospatiale group, launched the first two Brasilsat satellites in February 1985 and March 1986. Until 1994 the military directed most of the space program through the Ministry of Aeronautics, which is in charge of the CTA. Created in 1950, the CTA is involved in research and development for the aerospace programs of the FAB (Brazilian Air Force). In 1965 the FAB created the Space Activities Center (Instituto de Atividades Espaciais—IAE), one of several institutes within the CTA, to develop rockets. Since its creation, the IAE has tested more than 2,000 rockets. In 1971, a joint civilian-military committee, the Brazilian Commission for Space Activities (''Comissão Brasileira de Atividades Espaciais--Cobae''), was established and placed under the CSN (National Security Council). Cobae was chaired by the head of the Armed Forces General Staff (Estado-Maior das Forças Armadas—EMFA) and was in charge of the Complete Brazilian Space Mission (''Missão Espacial Completa Brasileira--MECB''). The MECB was created in 1981 to coordinate launch vehicles, launch sites, and the manufacturing of satellites. On the civilian side, the MECB is headed by the INPE. Established in 1971, the INPE replaced the National Commission for Space Activities (''Comissão Nacional de Atividades Espaciais--CNAE''). The INPE is subordinate to the Ministry of Science and Technology and roughly the CTA's counterpart. The INPE develops satellites and conducts space and meteorological research. It has also been developing engines using liquid propellants since 1988, but with mixed results. Within Brazil's MECB, civilians have been primarily responsible for satellite production, and the armed forces have been in charge of developing launch pads and rockets. Despite this division of labor, the armed forces were the dominant actors in the MECB, at least through 1993. Military officers occupied most of the high-ranking positions in the MECB. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Brazilian space program」の詳細全文を読む スポンサード リンク
