BepiColombo is en route to Mercury and will conduct its first Mercury flyby in October 2021. The trajectories of BepiColombo during these flybys are unique and will bring new insights into Mercury’s plasma environment. Although their field of view is limited, some instruments within the Mercury Plasma Particle Experiment (MPPE) consortium onboard Mio/BepiColombo will be operated during these flybys. Unlike Mariner-10 ion measurements will be obtained, and unlike MESSENGER, low energy electrons and ions will be measured simultaneously. Thus we have revisited Mariner-10 and MESSENGER observations with the help of the hybrid model LatHys in order to constraint the plasma environment that will be encountered by BepiColombo during its forthcoming Mercury flybys.
