Whitepaper #401 in the Decadal Survey for Solar and Space Physics (Heliophysics) 2024-2033. Main topics: basic research. Additional topics: inner heliosphere; solar physics; space-based missions/projects.
With solar sailing propulsion capable of reaching the velocities of ~5–10 AU/year, missions to the Jovian system would take 2 years, and missions to Saturn, 3. Fast, low-cost, maneuverable sailcraft open new opportunities for solar system exploration. Missions may cost only a few tens of millions of dollars and could be modularized to reach different destinations with different instruments.
