The Solar Orbiter mission, a joint ESA–NASA effort, is currently exploring the inner heliosphere with an orbital inclination of ~25° relative to the ecliptic, and is on track to exceed 30° by 2027, ultimately reaching ~33°. These progressively higher latitudes provide unprecedented views of the solar poles and the Sun’s global structure. The mission’s rich in-situ and remote-sensing data have already advanced our understanding of solar–heliospheric connections, the origins of the solar wind, and solar dynamics. As Solar Orbiter reaches higher latitudes, it will deliver more direct observations of the polar regions, offering critical constraints on the solar dynamo and global magnetic field. This session invites contributions highlighting key discoveries to date, as well as studies focused on the upcoming high-latitude phase, including observations from Solar Orbiter’s unique vantage point, coordinated analyses with other assets, numerical simulations, and theoretical work that deepen our understanding of Sun–heliosphere coupling.
