The PUNCH mission (starts at 8:05) NASA’s new mission to study the Sun is called PUNCH (Polarimeter to Unify the Corona and Heliosphere).  In this episode of How on Earth we talk with solar physicist Dr. Craig DeForest, the Principal Investigator of the PUNCH mission.  Dr. DeForest is a Program Director at the Boulder office of Southwest Research Institute, and he explains how PUNCH will use polarimetry to study the outer part of the solar atmosphere, the million-degree hot corona, and how it interacts and evolves into the solar wind.
