Whitepaper #171 in the Decadal Survey for Solar and Space Physics (Heliophysics) 2024-2033. Main topics: basic research. Additional topics: other basic research; inner heliosphere.
While the near-term Interstellar Probe mission will revolutionize our understanding of our astrosphere, it will provide only a snapshot of the history of the heliosphere. Trans-Neptunian objects (TNOs), with numerous options located along any Interstellar Probe trajectory, provide an opportunity to study the history of the heliosphere using the colors, spectra, and geologies of their surfaces.
