Imaging the Young Solar Wind with PUNCH 

Craig DeForest 
Southwest Research Institute 

The solar corona and solar wind are intimately connected, but have - to date - been studied in very different ways. Two NASA missions are working to unify the fields of coronal physics and solar wind physics. Parker Solar Probe (PSP) is bringing in-situ methods directly to the solar corona. The Polarimeter to UNify the Corona And Heliosphere (PUNCH) is an in-development mission to bring imaging techniques outward into the solar wind itself. PUNCH in particular yields a global and cross-scale perspective on solar wind phenomena, that complements the “ground truth” of direct local measurement by PSP during its perihelia. 

90 days after a planned 2024 launch, the four PUNCH smallsats will form a planet-sized wide-field camera with a 90° wide field of view centered on the Sun, imaging from 1.25° to 45° from the Sun in all directions. The mission will use sensitive photometric imaging to study the origins of the young solar wind as it disconnects from the corona; and polarization measurements to track space-weather-relevant disturbances in 3D through the heliosphere. 

I will describe and illustrate the PUNCH science objectives and approach, discuss how they interact with current results coming from Parker Solar Probe, and provide updates on the status of the mission as we move toward PDR and KDP-C in the spring of 2021.
