Abstract:
• The heliosphere is a large cavity carved by the solar wind into the local interstellar medium.
A survey of the structure and dynamics of the solar corona and the associated heliosphere is given. Their basic properties and variations are discussed.
• The solar wind in its various forms originates in the magnetically highly structured solar corona.
Selected observations and concepts of solar wind acceleration and coronal heating are addressed.
• The heliospheric plasma encompasses particles, waves and turbulence from different sources.
The role that turbulence plays in plasma dynamics and heating and some related kinetic processes are outlined.
