AB: We present the most recent results from our continuing studies of the interaction of the solar wind with Mars. In our 3D multi-species MHD model, the Martian ionosphere is assumed to consist of O2+, O+ and CO2+ ions, while the solar wind is represented by protons. Chemical reactions involving these ions, such as photoionization, charge exchange and recombination are included in the model self-consistently. The effects of the crustal magnetic field and the hot oxygen and thermal hydrogen corona are evaluated by using a spherical co-ordinate system, which allows an altitude resolution of 10 km within the ionospheric region.
