Much of what we know about the solar wind's interaction with the Earth's magnetosphere
has been gained from isolated in-situ measurements by single or multiple spacecraft. Based
on their observations, we know that reconnection, whether on the dayside magnetopause or
deep within the Earth's magnetotail, controls the bulk flow of solar wind energy into and
through the global system and that nightside activity provides the energized particles that
power geomagnetic storms. But by their very nature these isolated in-situ measurements …

Abstract The Solar Terrestrial Observer for the Response of the Magnetosphere (STORM) is
one of five NASA MIDEX mission concept studies. STORMs overarching science goal is to
quantify the global circulation of energy that powers space weather in the coupled solar
wind-magnetosphere system. STORM tracks and quantifies the energy input into and
through the magnetosphere using a comprehensive suite of in situ and imaging instruments
coupled with high-fidelity ground-based observations to globally image the critical plasma …
