It aims to address the overarching questions of how the Sun creates and controls the heliosphere, and why solar activity changes with time. Among the instruments that Solar Orbiter carries is the Polarimetric and Helioseismic Imager (SO/PHI), which is the first magnetograph to leave the Sun-Earth line and to observe the Sun from different directions. Solar Orbiter is still in its cruise phase and SO/PHI is still undergoing various tests, improvi...
