AB: The Galileo mission demonstrated the extensive and varied interactions between the Jovian magnetosphere and the icy Galilean satellites. In particular, the Galileo plasma wave investigation showed the surprisingly complex array of plasma and radio wave phenomena accompanying Ganymede's magnetosphere, evidence of an extensive magnetospheric interaction at Europa, and a weaker yet highly variable interaction at Callisto. The plasma wave observations showed that all three moons were sources of plasma for the Jovian magnetosphere. Furthermore, the Galileo observations of Jovian radio emissions extended those of earlier Voyager and Ulysses and provided unique insight into the dynamics of the Jovian magnetosphere. The Jupiter Icy Moons Orbiter (JIMO) offers important extensions to the Galileo studies mentioned above. Primarily, the ability to orbit each of these moons will enable much more complete maps of the magnetospheric interactions than possible with even the multiple flybys provided by Galileo. More importantly, however, the additional power and data volume promised by the JIMO spacecraft means that the microphysics of these interactions can be addressed, given an accompanying set of fields and particles instruments. JIMO also provides the possibility of actively sounding the ionospheres of the moons to obtain complete ionospheric profiles along the orbit and down to the surface. In addition, JIMO provides the opportunity to make important advances in the study of the Jovian magnetosphere and its extensive array of radio emissions. The resources available on this platform would enable extensive direction-finding and polarization studies of the radio emissions from anywhere along the orbit as has been demonstrated by the Cassini Radio and Plasma Wave Science instrument. The periods in orbit about the moons provide multiple occultations of the higher frequence radio emission sources (decametric and hectometric) so that direction-finding can be performed without complication from the complex antenna patterns usually found at the higher frequencies.
