Introduction:

The solar magnetic field is crucial in heating the solar corona, accelerating the solar wind, and shaping the structure of the solar corona and heliosphere. However, many unresolved questions remain, and addressing them is essential for advancing our understanding and improving space weather predictions from the Sun to Earth.

Scientific Questions:

How well do we need to understand coronal heating/solar wind acceleration to model the solar wind for space weather applications?
How well can models describe the connectivity of interplanetary locations to their solar sources (mapping)?
Is the open magnetic flux primarily rooted in coronal holes? If so, why do we systematically underestimate it?
Is the slow solar wind predominantly steady or dynamic? Is a dynamic description essential for accurate space weather models?
