Missions are being studied to the systems and moons of outer planets, including extended observation periods by local orbiters or possible landers, that require careful evaluation of the local radiation, plasma, microparticle, atmospheric and plume environment for design of both platform and science payload. Radiation impact potentially includes total cumulative doses, single event effects from short term enhancements and internal charging risk whilst plasma environments present risks of surface charging. Behaviour of the plasma environment and mechanisms for trapping, acceleration, losses for electrons and protons in the outer planet radiation belts are not very well known. Highly tilted global magnetic fields with respect to the planet rotation axis are believed to induce complex interactions with heliosphere. Of those planets in the solar system which possess significant magnetospheres, the Saturnian system is not as well characterised as Earth or Jupiter whilst not being described by models at all for Uranus and Neptune. Local (natural) microparticle environments are also important due to the large gravitational attraction of the gas giants and the potential for impact damage posing a risk to spacecraft.
