The topside sounding mode of the Mars Advanced Radar for Subsurface and Ionospheric Sounding (MARSIS) on the Mars Express Spacecraft (MEX) is able to make measurements of electron densities in the Martian ionosphere from both local electron plasma oscillations and remote soundings. Study of thousands of MEX orbits shows that in some cases the electron plasma oscillations disappear and reappear abruptly on the dayside ionosphere. At around 40° of SZA, the altitude of the first disappearance is around 600 km as the spacecraft is ascending. ASPERA-3 data show that when the plasma oscillations disappear the spacecraft is in the magnetosheath and when they return, the ionospheric plasma is observed. We therefore believe that these intermittent appearances of plasma are due to motion of the magnetosheath boundary while the spacecraft is in the transition region between ionosphere and magnetosheath. In this study, we use MARSIS local electron density measurements in conjunction with an established model of the magnetosheath boundary to describe oscillations of the ionosphere-magnetosheath boundary.
