Description
Summary:Based on discussions held at a workshop in Bra-Pollenzo, Italy, this paper elaborates upon 19 outstanding questions of plasma physics in the Earth's magnetosphere. The questions are grouped according to (a) driving processes, (b) radiation belt and ring current issues, (c) auroral physics, (d) internal plasma processes, and (e) magnetosphere-ionosphere mapping issues. Future needs for magnetospheric plasma physics (measurements, techniques, simulations, theories, studies) are outlined. •19 magnetospheric plasma physics questions were discussed in Pollenzo Italy.•Phenomena include aurora, radiation belts, ring current, cold particle populations.•Processes include reconnection, nonlinear waves, energy conversion, turbulence.•The 19 questions are each elaborated upon.•Future needs to answer these 19 outstanding questions are collected.
