The Eastern Range (ER) is an American rocket range that supports missile and rocket launches from the two major launch heads located at Cape Canaveral Air Force Station and the Kennedy Space Center (KSC), Florida.〔〔(【引用サイトリンク】title=Eastern Range (U) )〕 The range has also supported Ariane launches from the Guiana Space Centre as well as launches from the Wallops Flight Facility and other lead ranges.〔 The range also uses instrumentation operated by NASA at Wallops and KSC.〔 The headquarters of the range is now the 45th Space Wing at Patrick Air Force Base.〔 == History == The history of the Eastern Range began on October 1, 1940 with the activation of the Banana River Naval Air Station which supported antisubmarine sea-patrol planes during World War II. The station was deactivated and put into a caretaker status on September 1, 1947.〔〔(【引用サイトリンク】title= Fact Sheets : EVOLUTION OF THE 45TH SPACE WING )〕 Launches of captured German V-2 rockets had been ongoing since the end of World War II at White Sands Proving Grounds in New Mexico, but it became clear that a much longer range away from heavily populated areas would be needed. The Joint Research and Development Board established the Committee on the Long Range Proving Ground in October, 1946 to study locations for such a range, with three potential sites emerging: along the northern coast of Washington with a range along the Aleutian Islands; El Centro, California, with a range along the Baja peninsula; and Banana River Naval Air Station with a launch site at Cape Canaveral and a range over the Bahamas and into the Atlantic Ocean.〔〔 The Washington site was quickly discarded due to difficulties with support due to cold weather and remoteness.〔 El Centro was put forth as the primary choice (due to being close to missile manufacturers) with the Cape as second choice.〔〔 However, the El Centro site had to be abandoned after a wayward V-2 missile from White Sands crashed into a cemetery in Juarez, Mexico, leading to then Mexican President Aleman refusing to allow missiles to overfly Baja.〔〔 The Navy transferred the Air Station to the Air Force on September 1, 1948〔 and it remained on standby status. On May 11, 1949, President Truman signed Public Law 60 which established the Joint Long Range Proving Ground.〔〔〔(【引用サイトリンク】title=Chronology of work stoppages and related events, KSC NASA and AFETR through July 1965 )〕 On June 10, 1949, the Banana River Naval Air Station was redesignated the Joint Long Range Proving Ground Base and Advance Headquarters, Joint Long Range Proving Ground and the Air Force Division, Joint Long Range Proving Ground was established.〔〔〔 On May 16, 1950 and May 17, 1950, range and base dropped the "Joint" in their names due to a DOD decision earlier in the year to put the range exclusively under Air Force jurisdiction.〔〔 On July 24, 1950, Bumper #8 became the first missile to launch from the Cape.〔〔 The Long Range Proving Ground Base was renamed Patrick Air Force Base on August 1, 1950, in honor of Major General Mason M. Patrick and the following year, on June 30, 1951, the Joint Long Range Proving Ground Division became the Air Force Missile Test Center and the Joint Long Range Proving Ground became the Florida Missile Test Range.〔〔〔 These would not be the only name changes for the range or the agency that controlled it. The Florida Missile Test Range was renamed the Atlantic Missile Range〔〔〔 in 1958 and the Eastern Test Range in 1964; the Air Force Missile Test Center was redesignated the Air Force Eastern Test Range (AFETR)〔〔〔 in 1964, then control of the range was transferred to Detachment 1 of the Space and Missile Test Center located at Vandenberg Air Force Base when AFETR was deactivated on February 1, 1977, which put both the Eastern and Western ranges under the same leadership.〔〔 On October 1, 1979, control of the range passed to the newly activated Eastern Space and Missile Center (ESMC).〔〔 The ESMC was transferred from Air Force Systems Command to Air Force Space Command on October 10, 1990; finally, on November 12, 1991, the 45th Space Wing was activated and assumed operational control for the range from ESMC;〔〔 on the same day the Eastern Test Range became the Eastern Range.〔 The transition on the west coast occurred one week later on November 19, 1991, when the Western Space and Missile Center became the 30th Space Wing and the Western Test Range became the Western Range.〔(【引用サイトリンク】title=Space Vehicles : History Office : History Office )〕〔(【引用サイトリンク】title=VAFB )〕 The current Range Contractor is Computer Sciences Raytheon.〔http://computersciencesraytheon.com/home.html CSR homepage〕 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「Eastern Range」の詳細全文を読む スポンサード リンク
