Whitepaper #202 in the Decadal Survey for Solar and Space Physics (Heliophysics) 2024-2033. Main topics: basic research; infrastructure/workforce/other programmatic. Additional topics: system science; research tools and infrastructure.
The next era of Heliophysics should focus on the Sun-Heliosphere and Geospace as system-of-systems. We recommend a coordinated, deliberate, worldwide scientific effort to answer long-standing questions that will remain unanswered without a unified program.
