'''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. The ODINUS mission concept proposes to expand the [[Uranus orbiter and probe]] mission to two twin orbiters— dubbed ''[[Freyr]]'' and ''[[Freyja]]'', the twin gods of the [[Norse pantheon]].<ref>[http://odinus.iaps.inaf.it/wp.php#ln12 The ODINUS Mission Concept].

==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.
