By approaching as close as 48 solar radii, Solar Orbiter will view the solar atmosphere with high spatial resolution and combine this with measurements made in-situ. Over the extended mission periods Solar Orbiter will deliver images and data that will cover the polar regions and the side of the Sun not visible from Earth. Solar Orbiter will coordinate its scientific mission with NASA's Solar Probe Plus within the joint HELEX programme (Heliophysics Explorers) to maximise their combined science return.
