SOLAR〔(SOLAR: three years observing and ready for solar maximum - ESA )〕 is an ESA science observatory on the Columbus Laboratory, which is part of the International Space Station. SOLAR was launched with Columbus on February 2008 aboard STS-122. It was externally mounted to Columbus with the European Technology Exposure Facility (EuTEF). SOLAR has three main space science instruments: SOVIM, (SOLSPEC ) and SOL-ACES.〔(Sun Monitoring on the External Payload Facility of Columbus (Solar) )〕 Together they provide detailed measurements of the Sun's spectral irradiance.〔(【引用サイトリンク】title=Solar Package on ISS )〕 The SOLAR platform and its instruments are controlled from the (Belgian User Support and Operations Centre ) (B.USOC), located at the (Belgian Institute for Space Aeronomy ) (BISA) in Uccle, Belgium. *SOVIM (''So''lar ''V''ariantions and ''I''rradiance ''M''onitor) instrument is based on an earlier instrument (SOVA) which flew aboard the European Retrievable Carrier, launched on STS-46 in 1992. It is designed to measure solar radiation with wavelengths from 200 nanometers - 100 micrometers. This covers near-ultraviolet, visible and infrared areas of the spectrum. *(SOLSPEC ) (''Sol''ar ''Spec''tral irradiance measurements) is designed to measure the solar spectral irradiance in the 165 - 3000 nanometer range with high spectral resolution. *SOL-ACES (''A''uto-''c''alibrating ''E''xtreme Ultraviolet and Ultraviolet spectrometer''s'') consists of four grazing incidence grating spectrometers. They are designed to measure the EUV/UV spectral regime (17 nanometers - 220 nanometers) with moderate spectral resolution. The mission was originally planned for a 2003 launch, but was delayed following the Space Shuttle Columbia disaster. Some other components are also planned to be mounted externally on Columbus on future missions, including the Atomic Clock Ensemble in Space (ACES). Another name for SOLAR may be Solar Monitoring Observatory or SMO. In 2012, the entire 450 tonne station was rotated so SOLAR could observe a full rotation of the Sun continuously.〔(International Space Station )〕 A Solar rotation takes about 24–28 days depending on the latitude.〔Solar rotation〕 ==Visuals== 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「SOLAR (ISS)」の詳細全文を読む スポンサード リンク
