  The National Science Foundation (NSF) Daniel K. Inouye Solar Telescope
(DKIST) is about to start operations at the summit of Haleakala (Hawaii). DKIST
will join the early science phases of the NASA and ESA Parker Solar Probe and
Solar Orbiter encounter missions. By combining in-situ measurements of the
near-sun plasma environment and detail remote observations of multiple layers
of the Sun, the three observatories form an unprecedented multi-messenger
constellation to study the magnetic connectivity inside the solar system. This
white paper outlines the synergistic science that this multi-messenger suite
enables.
