Whitepaper #377 in the Decadal Survey for Solar and Space Physics (Heliophysics) 2024-2033. Main topics: basic research; infrastructure/workforce/other programmatic. Additional topics: other basic research; outer heliosphere; other programmatic; space-based [...]
We focus on the synergies between heliosphere and dust science and illustrate how to use interstellar dust (ISD) in the solar system as a tracer for the (dynamic) heliosphere properties. We discuss the potential role of cosmic dust in heliospheric physics. An Interstellar Probe with dust suite would bring great advances to ISD research, and can contribute, through the dust, to heliosphere science.
