Understanding the origins and propagation of both the fast and slow solar wind is vital for better comprehending our surrounding cosmos but also for being able to reliably predict space weather conditions overall. The arrival of novel missions such as the Parker Solar Probe, Solar Orbiter and BepiColombo have brought a wealth of data that cover previously inaccessible heliospheric locations, in an effort to make decisive steps towards this direction. In combination with future missions, such as Vigil, these cutting-edge missions call for use of new models and data analysis techniques that will help us advance our physical understanding and establish links between phenomena occurring across the whole heliosphere. In this session, we welcome all contributions based on theory, data-driven modelling, and/or multiple ground-based or space observations of solar wind from source to in-situ detection. We will consider submissions focusing on solar wind formation, propagation and on its impacts on Earth and other solar system bodies. Studies on the sources of slow and fast solar wind, heating and acceleration processes, large-scale structure and small-scale dynamics, as well as open magnetic field topologies and connectivity across the corona and heliosphere will be gladly received. Insights for future directions in solar wind research will also be highly considered.
