Codenamed Lanyard, the KH-6 was the unsuccessful first attempt to develop and deploy a high-resolution optical reconnaissance satellite by the United States National Reconnaissance Office.〔(【引用サイトリンク】 url=http://www.fas.org/irp/nro/declass.pdf )〕 Launches and launch attempts spanned the period from March to July 1963. The project was quickly put together to get imagery of a site near Tallinn suspected of having anti-ballistic missiles. The satellite carried Itek's "E-5" camera developed for the Samos program, which had been cancelled. The camera had a focal length of 1.67 meters (66 inches) and could discern objects on the ground 1.8 m (6 ft) in size. The ground swath of the camera was 14 km by 74 km (9 mi by 46 mi). The satellite weighed 1500 kg, and had a single re-entry vehicle in which exposed film was returned to earth for a mid-air〔Federation of American Scientists (FASorg: ''KH-6'' )〕 aircraft recovery. The KH-6 was manufactured by Lockheed and launched from Vandenberg Air Force Base on Thor-AgenaD rockets. Three launch attempts were made. One attempt failed and another did not use any film. The film canister contained over 2,250 feet of film with 910 photographic frames.〔 ==Launches== * KH-6 8001 launch failed 1963-03-18 (NSSDC ID No. P11 (1963-F03) ) * KH-6 8002 launched 1963-05-18 (NSSDC ID NO. 016A 1963-016A ) * KH-6 8003 launched 1963-07-31 (NSSC ID NO. 1963-032A ) (NSSDC ID Numbers: ''See'' COSPAR) 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「KH-6 Lanyard」の詳細全文を読む スポンサード リンク
