Solar wind Magnetosphere Ionosphere Link Explorer (SMILE) is a planned joint venture mission between European Space Agency and Chinese Academy of Sciences studying interaction between Earth's magnetosphere and solar wind. Launch is expected at the end of 2021. == Overview == SMILE spacecraft will be equipped to simultaneously capture images and movies of magnetopause, polar cusps, and aurora.〔 Previously spacecraft analyzed data only locally, however a recent discovery of the fact that magnetosphere emits X-rays will allow SMILE to capture more comprehensive data than previous missions did.〔 Key instruments on board the spacecraft will include:〔 * Soft X-ray Imager (SXI) – used to study interaction of solar wind with Earth's magnetosphere. Telescope will be developed by the scientists from University of Leicester. * UV Imager (UVI) – used to observe and measure aurora borealis along with identifying polar cap boundary. Telescope will use four-mirror design along with new filters. * Light Ion Analyser (LIA) – on site measurement of ions in the solar wind. * Magnetometer (MAG) – on site measurement of magnetic fields. Spacecraft will be launched in 2021 to Molniya orbit with apogee of 20 (Earth radii, where 1 = 6,371 km) using Chinese Long March 2C rocket. Mission cost is estimated to be .〔 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 wind Magnetosphere Ionosphere Link Explorer」の詳細全文を読む スポンサード リンク
