Whitepaper #301 in the Decadal Survey for Solar and Space Physics (Heliophysics) 2024-2033. Main topics: basic research. Additional topics: outer heliosphere; emerging opportunities.
The physical conditions within our heliosphere are driven by the Sun’s motion through an evolving interstellar environment that remains largely unexplored. We discuss the critical science enabled by interdisciplinary studies that connect spacecraft observations of the heliosphere’s immediate interstellar environment to remote observations of the interstellar medium and other star-ISM interactions.
