讲座摘要

The main scientific goals of Parker Solar Probe (PSP) are to help unravel the origin and structureof the solar corona and the processes responsible for the acceleration of the solar wind and ofsolar energetic particles. Until now PSP has accomplished 16 orbits around the Sun, approachingit to a distance of 13.4 solar radii and has become the first spacecraft travelling to the outeratmosphere of a star. PSP will reach its closest distance to the Sun on 24th December 2024 at adistance below 10 solar radii. Its technical design allowed to withstand the Sun's heat and tooperate the scientific instruments flawlessly. Each encounter has brought new spectacular data,sampling for the first-time structures of the solar corona and solar wind below the sub-alfvenicregime, from within coronal mass ejections (CMEs) and during crossings of coronal streamerswith its embedded heliospheric current sheet (HCS). Beyond breakthroughs in solar andheliospheric physics, PSP has facilitated spectacular views of planets, asteroids, and comets, andthe interplanetary distribution of dust particles. In my talk, I will introduce the basic missionconcept and provide a brief summary of the new observations. The focus will be on thecontribution of the CGAUSS (coronagraphic German and US Parker Solar Probe Survey) project tothe WISPR (Wide-field Imager for Solar Probe) camera led by the University of Göttingen.
