Whitepaper #008 in the Decadal Survey for Solar and Space Physics (Heliophysics) 2024-2033. Main topics: basic research. Additional topics: inner heliosphere.
To address the fundamental gap in our knowledge of the heliosphere at mesoscales, new dedicated mesoscale missions are required in the next decade. This white paper outlines the current gaps in our understanding resulting from limited measurements at this critical scale and the need for an asserted effort in addressing these gaps.
