The Solar Orbiter mission, an international cooperation between ESA and NASA, is currently orbiting the Sun with an orbital inclination of 17° (24° from December 2026 onwards) at heliocentric distances between 0.95 to 0.29 au, providing a new perspective of the Sun’s polar regions. As the mission continues towards its max. inclination of ~33° in June 2029, it is an exciting time to study dynamics within the solar atmosphere and the inner-heliosphere from this unique perspective.

The overall goal of Solar Orbiter is to understand how the Sun creates and controls its atmosphere and the heliosphere. The mission provides unprecedented imaging of the Sun’s photosphere, chromosphere, and corona, enabling studies of the origin and evolution of the Sun’s atmosphere, the solar wind, flares, solar eruptions, and energetic particle events. The combination of high-resolution imaging and simultaneous in-situ measurements from Solar Orbiter’s inner-heliospheric vantage point offers a unique opportunity to link solar sources directly to their heliospheric impacts.

This session invites contributions that address the Solar Orbiter science objectives, exploit multi-mission data sets, and studies involving the dynamic solar atmosphere to the inner-heliosphere. We also welcome Solar Orbiter-related contributions in the fields of theory and numerical simulations that contribute to a better understanding of the solar origins of heliospheric variability and space weather.
