ODINUS (Origins, Dynamics, and Interiors of the Neptunian and Uranian Systems) is a space mission concept proposed to the European Space Agency's Cosmic Vision programme, consisting on a pair of orbiters. The ODINUS mission concept proposes to expand the Uranus orbiter and probe mission to twin spacecraft— dubbed ''Freyr'' and ''Freyja'', the twin gods of the Norse pantheon.〔(The ODINUS Mission Concept ).〕 Their primary mission would be to study Neptune and Uranus with one orbiter each.〔(【引用サイトリンク】 title=The ODINUS Mission )〕 ==Instruments== The following six instruments are considered essential to the mission: *Camera (Wide and Narrow Angle) - Designed to image the planet at the same level of detail as missions to the two gas giants have provided. *VIS-NIR Image Spectrometer *Magnetometer - To study the magnetic fields of Neptune. *Mass Spectrometer (Ions and Neutrals, INMS) *Doppler Spectro-Imager - To take seismic measurements. *Microwave Radiometer The following two additional instruments are strongly desired by the mission proposers: *Energetic Neutral Atoms Detector - To complement the measurements of the INMS. *High-sensitivity Accelerometer - To be used in the atmospheric descent phase. 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「ODINUS」の詳細全文を読む スポンサード リンク
