AB: With the discovery of energetic particle injections within Saturn's inner magnetosphere, substorm-like dynamics in Saturn's near-planet magnetotail, and solar-wind driven dynamics of Saturn's aurora, Saturn joins Jupiter and Earth as having a space environment that hosts an array of complex, seemingly familiar dynamical features. The lesson here may be that the transport of mass and energy within and throughout complex magnetized plasma systems proceeds by means of transient "fits and starts" rather than by means of smoothly continuous processes. It is of substantial interest to determine the extent to which the dynamic phenomena involve the same fundamental physical processes. For example, with injection processes observed within all three magnetospheres, to what extent does magnetic energy storage and release play a role, irrespective of whether the energy source is the interplanetary environment or the rotation of the planet? Here we review what is known about the dynamics of Saturn, Jupiter, and Earth to address the degree to which they involve fundamentally distinct or similar physical processes.
