Whitepaper #399 in the Decadal Survey for Solar and Space Physics (Heliophysics) 2024-2033. Main topics: basic research. Additional topics: fundamental space plasma theory; emerging opportunities.
Earth’s magnetotail is an ideal natural laboratory to study particle acceleration associated with magnetic reconnection; dedicate research there. Heliophysics should also consider studying reconnection-related acceleration in other space plasma environments including: solar and solar wind; Jupiter’s magnetosphere; Uranus’ magnetosphere; the heliosheath, heliopause, and local interstellar medium.
