The Sun-2-Stars (S2S) mission uses the first nearly circular-polar orbit (~5 au, 65° inc), enabling a suite of in situ observations and remote imaging to explore the linked system from the polar-3D Sun through the heliosphere and into the interstellar medium. S2S is the next step in Heliophysics, unifying our 3-D view of solar interactions from the Sun out to the galactic environment.
