Investigation of the Solar Wind in the Solar Corona and Heliosphere

The solar wind is the focus of multiple open questions in solar and heliospheric physics. These questions include how the solar wind creates and controls the inner heliosphere, how the solar corona transitions from the photosphere to the inner heliosphere, how corotating interaction regions (CIRs) in the solar wind are generated, how coronal mass ejections (CMEs) are formed and interact with the solar wind? The WISPR optical telescope on the recently launched Parker Solar Probe (PSP) was designed to investigate these open questio...
