SwissCube-1 is a Swiss satellite operated by Ecole Polytechnique Fédérale de Lausanne (EPFL). The spacecraft is a single unit CubeSat, which was designed to conduct research into nightglow within the Earth's atmosphere, and to develop technology for future spacecraft. It has also been used for amateur radio. It was the first Swiss satellite to be launched. SwissCube-1 was launched by a Polar Satellite Launch Vehicle, serial number C14, flying in the Core Alone, or PSLV-CA, configuration. The launch took place from the First Launch Pad at the Satish Dhawan Space Centre, at 06:21 UTC on 23 September 2009. SwissCube-1 was a secondary payload aboard the rocket, which deployed the Oceansat-2 satellite. Five other secondary payloads were flown aboard the rocket; BeeSat, UWE-2, ITU-pSat1, Rubin 9.1 and Rubin 9.2. SwissCube-1 is operating in a sun synchronous orbit with an apogee of , a perigee of and 98.28 degrees of inclination to the equator. It has an orbital period of 98.5 minutes. Its mission was expected to last between three and twelve months.〔 The mission was extended an additional 18 months in February 2010 and an additional ground command facility was added.〔(【引用サイトリンク】url=https://s3.amazonaws.com/eatops/Article+de+presse+centres_de_controle_d%C3%A9port%C3%A9s_mission_SwissCube.pdf )〕 It took its first picture on 18 February 2011 and its first airglow picture on 3 March 2011.〔(【引用サイトリンク】accessdate=2013-08-08 )〕 On 2 December 2011, EPFL ended the SwissCube project and turned over control of the satellite to amateur radio operators. SwissCube is still operational. == See also == * 2009 in spaceflight * List of CubeSats 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「SwissCube-1」の詳細全文を読む スポンサード リンク
