Exploring the solar poles: The last great frontier of the sun

Observations of the Sun’s poles is fundamental to understanding and predicting the solar cycle, constraining polar kilo-Gauss flux patches and plasma jets and illuminating the origin of the fast solar wind. This white paper argues the case for novel out-of-ecliptic observations of the Sun’s polar region in conjunction with existing or future multi-vantage point heliospheric observatories.
