The Solar Orbiter Mission
By approaching as close as 0.28 AU, Solar Orbiter will view the Sun with high spatial resolution and combine this with in-situ measurements of the surrounding heliosphere. Thanks to its unique orbit, Solar Orbiter will deliver images and data of the unexplored Sun's polar regions and the side of the Sun not visible from Earth.
