Abstract | The Parker Solar Probe (PSP) mission has been studied since 1958. After many iterations and changes in design, the mission was launched on August 12, 2018 (see, https://www.nasa.gov/content/goddard/parker-solar-probe). PSP has completed its 3rd rendezvous with Venus and 6th perihelion passage. Each flyby brings PSP closer to the Sun (eventually to 9.7 solar radii). In October 2020 it flew within 20 solar radii of the solar surface. A goal of the mission is to determine how the solar corona is heated to ∼ a million degrees. In addition, using both magnetic field and plasma data, the mission will facilitate studies of the transition from coronal to solar wind conditions and will help to determine the processes controlling the onset of magnetofluid turbulence in the corona. Of particular focus is the study how “switchbacks” in the magnetic field form and evolve. Those transitions are seen where the flow evolves from a striated pattern to a flocculated one. |
