  We explore new opportunities for solar physics that could be realized by
future missions providing sustained observations from vantage points away from
the Sun-Earth line. These include observations from the far side of the Sun, at
high latitudes including over the solar poles, or from near-quadrature angles
relative to the Earth (e.g., the Sun-Earth L4 and L5 Lagrangian points). Such
observations fill known holes in our scientific understanding of the
three-dimensional, time-evolving Sun and heliosphere, and have the potential to
open new frontiers through discoveries enabled by novel viewpoints.
