Mars lacks a global magnetic field like Earth, allowing the solar wind to interact directly with its upper atmosphere. However, strong magnetic fields in Mars’ crust prevent solar wind from reaching the surface, creating a complex magnetic environment. As the solar wind flows past the planet, it forms a current sheet that plays a key role in atmospheric ion loss. Most simulations assume the strongest crustal magnetic fields are facing the dayside, limiting our understanding of the current sheet evolution as Mars rotates. In this study, we use a physics-based simulation to examine how the current sheet varies with longitude. We find that the orientation of the crustal fields affects whether the magnetotail current sheet is uniform or divided. These results show that the crustal field orientation has a significant impact on the structure of the Martian magnetotail.
