Understanding the evolution of Solar System diversity is a top-level question identified by the 2006 NASA Solar System Exploration Roadmap. The satellite systems of Jupiter and Saturn provide opportunities to compare the very different evolutions of satellites which likely had similar starting points. These satellite systems range from currently active (Io and Enceladus) to geologically dead (Callisto and Mimas). Different satellites have evidently experienced radically different thermal histories, but as yet few quantitative constraints on these histories have been published.

This proposal would directly investigate the global character of Pluto's atmosphere and its two-way feedbacks with N2 ice on the surface by combining a state-of-the-art three-dimensional atmospheric model with a detailed surface/subsurface thermal model.

PI Beyer proposes several scientific, mission support, and public outreach activities that include investigations on Mars, the Moon, the satellites of Jupiter and Saturn, and Pluto.

Investigation into the source of the solids that led to the formation of the regular satellites of the giant planets.

Investigation into whether the regular satellites of Jupiter and Saturn formed in gas-poor or gaseous environments. This information assists with accurate interpretation of satellite observations.
