Whitepaper #203 in the Decadal Survey for Solar and Space Physics (Heliophysics) 2024-2033. Main topics: basic research. Additional topics: system science.
Magnetospheric physics lacks a cohesive international scientific framework. To make substantial progress during the next decades, we suggest a coordinated, worldwide effort, which we call the International Geospace Systems Program (IGSP), to study Geospace as a system of systems, with particular emphasis on resolving mesoscale dynamics, where significant science questions remain.
