The solar atmosphere is a complex environment filled with a plethora of both highly dynamic and more stable features that occur across a huge range of temporal and spatial scales. Although we have made significant progress towards understanding many of these events in isolation over the past decades, we still do not know how they combine to contribute to the biggest open problems in the field, including how the solar corona is heated and how the solar wind is driven.

Making progress towards solving these problems has proved difficult not only because of the breadth of high-quality data required (in terms of spatial, temporal, and spectral resolutions), but also because we have traditionally been limited to observations along the Sun-Earth line (with a few exceptions).

Therefore, making inferences about the three-dimensional structuring of the solar atmosphere and how it links to the solar wind has been impossible. The launch of Solar Orbiter, however, is driving a paradigm shift in this area, with researchers now having access to an array of unique, coordinated datasets sampled at various observing angles (compared to the Earth) by the world-leading suite of ten different instruments carried onboard the spacecraft. Additionally, targeted observations coordinated with novel earth-based infrastructure, such as the Daniel K. Inouye Solar Telescope (DKIST) and the Interface Region Imaging Spectrograph (IRIS), has heralded an exciting new era of multi-messenger solar physics.

As Solar Orbiter progresses through the first few years of its science operations, now is the perfect time to bring together the community through an RAS Specialist Discussion Meeting to learn more about the instrumentation, to discuss important early results, and to plan for the future of the mission.
