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.[1][2] Their primary mission would be to study Neptune and Uranus with one orbiter each.[3] If selected, ODINUS would launch in 2034.[4]
