One of the major concerns in the spacecraft design due to natural space environment interaction is the internal charging in dielectric materials and floating conductors, especially for missions encountering a high radiation environment such as NASA’s Juno and Europa Clipper Missions. Therefore, good assessment of the risk of iESD for a given space environment and dielectric geometry is important for spacecraft reliability. 

The first and one of most important task of the iESD assessment is to define the relevant environment for the internal charging phenomena of the given mission, which we call “iESD Design Environment”. We will show how the iESD design environments of Juno mission and Europa Clipper mission have been determined from their trajectories through statistical consideration.
