Abstract
The highest priority Planetary Flagship from the Planetary Science and Astrobiology Decadal Survey is the Uranus Orbiter and Probe. This mission enables broad, cross-disciplinary science of an ice giant system, including the planet, moons, rings, and magnetosphere. The ice giants represent a size class of planet that is largely unexplored but that is common among extrasolar planet systems. At the same time, Uranus is unique, possessing a regular satellite system, rings, and a complex magnetosphere surrounding a planet tilted over for extreme seasonal variation. Exploration of the Uranian system is guided by a broad suite of science Objectives and through remote sensing, in situ probe, and fields and particles experiments. Due to the rapid nature of the Decadal concept study, the orbital tour could not be perfectly optimized, but a best effort was made to include orbit insertion, probe release and relay, and multiple satellite flybys; some Objectives were necessarily better met than others by this tour. The mission's tour trajectory can be optimized to meet any of the Decadal Science Objectives, by focusing on a particular system target, for example magnetosphere, satellites, or planet interior, but the best tour will simultaneously meet the highest priority measurements for every Objective. The community-led (with no institutional or NASA sponsorship) poll described here was designed to collect broad science inputs on the tour parameters required for each Decadal Science Objective. Here we present results aggregated by Objective, as well as compared longitudinally, of the highest priority tour needs identified across all Objectives. Both the raw and aggregated data are made publicly available for future white papers, tour and trajectory work, as well as mission and instrument design teams, but the results are not binding nor decisional in any way.
