Whitepaper #018 in the Decadal Survey for Solar and Space Physics (Heliophysics) 2024-2033. Main topics: basic research. Additional topics: planetary magnetospheres; space-based missions/projects; system science.
Uranus is one of the most under-explored and least understood planetary magnetospheres in our Solar System. Some features in the single Voyager 2 flyby cannot be explained, or for which we only have a limited explanation, highlighting fundamental gaps in our Space Physics. This requires new data to resolve and in this White Paper we urge Heliophysics to support a Uranus Flagship mission.
