Direct observations of the Sun’s Polar Regions will open new windows into solar phenomena, long obscured from the ecliptic vantage point. A polar vantage point will allow us to place critical constraints on the solar dynamo through the measurement of the amplitude, structure and depth-dependence of high latitude flows. Moreover, such observations will provide new insight into how our star connects to the broader heliosphere, revealing the 3-D structure of the Sun's polar magnetic fields and high-speed solar wind. Direct polar observations will provide unique views for determining the magnetic orientation of CIRs, measuring the speed and direction of CMEs, and lifetime studies of Active Regions. This would significantly improve the inner boundary conditions used by models, enabling better space weather forecasts. In this session, we explore the observational and theoretical motivations that drive the growing need for a mission to directly image and explore the Sun’s Polar Regions.
