From the Executive Summary: The Jupiter system is a natural laboratory to study diverse and dynamic planetary processes. Its set of planet-sized moons serves as a solar system in miniature. In addition, Jupiter itself is an analog for the majority of extra-solar planets discovered to date. The Galilean moons, from volcanic Io to ancient icy Callisto, embody a variety of geological and geophysical processes, providing a window into solar system history by preserving in their cratering records a chronology dating from the present time back nearly 4.5 billion years. The presence of potential icy satellite subsurface oceans in the icy satellites has profound implications for habitability. The magnetosphere of Jupiter intimately interacts with its system of moons, transferring material throughout the system. Study of the internally generated magnetic field of Ganymede with comparison to the Earth and Mercury provides a basis to better understand planetary dynamos. Gaining insight into the composition and volatile inventory of Jupiter will shed light on how planets accrete from solar nebulae. Hence, a system-level investigation of the Jovian system will illuminate the question of how planetary systems form and evolve.
