Keywords:Imaging of Geospace, Future Satellite Mission

Global scale imaging of the dayside magnetosphere is an important observation subjects to understand the solar wind-magnetosphere coupling processes. Recent studies suggest that solar wind charge exchange soft X-ray (SWCX) emission from the dayside magnetosheath can be observed by the spacecraft, and several low-altitude satellites, for example, the Suzaku and XMM-Newton satellites, detected the SWCX emissions from the cusp regions. The SWCX emissions will be a diagnostic tool to understand the dynamic response of the terrestrial magnetosphere to the solar wind impact in a unique manner. In order to realize global scale imaging of the magnetosphere using the SWCX emissions, we are now planning the new satellite mission GEO-X that will be launched in early 2020s. In this presentation, we will present possible science subjects of the GEO-X mission with possible images of SWCX emissions estimated from the global-MHD simulation.
