II.5 Synergy between JMO, JGO, and JEO

II.5.1 Satellite science:

  • Take advantage of a complementary payload on the various mission elements (e.g., Radio and Plasma Wave instrument on JMO) to study the local electrodynamic environment of the Galilean moons by planning if possible dual/triple flybys of the moons (multi-point measurements, mainly at Ganymede and Callisto).
  • Take advantage of a complementary payload to study the magnetosphere/moon interactions by observing remotely (UV and Radio emissions) and in-situ (Plasma packages) the auroral footprints (at both ends of the field lines, i.e. in the Jovian atmosphere as well as in the atmospheres of the moons) of the Galilean moons.
  • Provide the magnetospheric context (JMO) from distance (ENA and UV emissions) to better understand the in-situ observations obtained in the vicinity of the Galilean moons by the JGO and JEO.

II.5.2 Magnetosphere science:

  • Study the coupling (electron beams, field-aligned currents) between the equatorial regions (JEO and JGO) and the high-latitude regions (JMO) of the magnetosphere, following Juno science.
  • Study the coupling between the inner magnetosphere (JEO), the middle magnetosphere (JGO) and the outer magnetosphere (JMO) of Jupiter by tracing the circulation of the magnetospheric plasma from its sources to its sinks.
  • Study the 3D structure (multi-point measurements) of the Jovian magnetosphere including its Local time asymmetries.
  • Detail the processes (radial diffusion in the equatorial plane and pitch angle diffusion at higher latitude) responsible for the acceleration of particles at the origin of the Jovian radiation belts.
  • Use one of the mission elements as a solar wind monitor when the other two mission elements orbit within the Jovian magnetosphere in order to detail the solar wind influence on the structure and dynamics of the Jovian magnetosphere (Jovian space weather).
  • Detail the global structure and dynamics of the Jovian ring current by remotely sensing its ENA emissions (JMO), as done by Cassini MIMI/INCA at Saturn or IMAGE at the Earth.
  • Use one of the mission elements (JMO with ENA imager and Radio and Plasma Wave instrument or JGO with UV Spectrometer) to remotely monitor the meteorology of the Io torus (Io space weather).
