Turbulent Magnetic Field Environments in the Induced Magnetotails of Venus and Mars

Venus and Mars, lacking global intrinsic magnetic fields, form induced magnetotails through their interactions with the solar wind. These regions exhibit dynamic magnetic field structures and turbulent fluctuations that play a key role in mediating energy dissipation and ion escape. While both planets form induced magnetospheres via the draping of interplanetary magnetic field lines around their ionospheres, differences in planetary parameters such as ionospheric conductivity, planetary size, and the presence of crustal magnetic fields on Mars may lead to distinct turbulence characteristics in their magnetotails. Using in situ observations from multiple spacecraft missions, we perform a systematic comparison of magnetic turbulence, magnetic field topologies, and associated current systems in the induced magnetotails of Venus and Mars. We characterize the spectral properties of magnetic fluctuations and examine their correlations with large-scale magnetic configurations. Our analysis reveals how turbulence modulates energy and mass transport in the magnetotails of Venus and Mars, providing insights into the comparative evolution of their space environments and atmospheric loss processes.
