Whitepaper #318 submitted to the Planetary Science and Astrobiology Decadal Survey 2023-2032. Topics: giant planets systems; ocean worlds; other planetary bodies: Triton
Global surface mobility is the key to comprehensive exploration of the diverse surfaces of worlds such as Triton. We propose to do this with a rocket-powered “hopper” vehicle. The same concept of using in-situ ices to refuel a radioisotope engine for global mobility would be applicable to other airless bodies in the solar system.
