CASMIUS mission concept targets Uranus to probe ice‑giant's rings, auroras and moons
CASMIUS is a mission concept to return to Uranus, targeting the ice giant's sideways rotation, complex ring system and unique moons. With Voyager 2 still the only spacecraft to visit, CASMIUS would aim to close major knowledge gaps and build on recent remote observations of Uranus' auroras and magnetosphere.
