Earth and Venus are similar in size, and the same fundamental physics governs the coupling of solar drivers into their magnetosphere - ionosphere - thermosphere systems. But unique properties of Venus, including very slow planetary rotation and a complete lack of intrinsic magnetic fields, provide an underused laboratory—better in some ways than the Earth—for the study of fundamental heliophysics processes, including the atmospheric escape processes that control planetary desiccation, ionosphere - magnetosphere coupling processes (particle acceleration, outflow, and precipitation), and the upper atmospheric dynamics needed to redistribute strong solar energy input from day to night. Venus is exposed to greater solar forcing than Earth, and offers a unique vantage point on the Sun and solar wind that alternates between being upstream from and antipodal to Earth. We welcome studies of Venus as a comparative heliophysics laboratory for plasma physics, ion-neutral coupling, upper atmosphere dynamics and chemistry, and heliosphere observations.
