Abstract An energetic neutral atom (ENA) is produced when a charge exchange reaction happens between an energetic ion and a neutral atom. At Mars, the energetic ions are typically solar wind protons and the neutrals are hydrogen atoms of the planetary exosphere. The ASPERA-3 experiment on Mars Express has provided the first measurements of ENAs at Mars. These measurements give a unique global view of the solar wind interaction with Mars. In the present study, the properties of hydrogen ENAs at Mars are investigated using a 3-D quasi-neutral hybrid model, which has been successfully applied to the study of solar wind-planet interactions at different planets, such as Mercury, Venus, and Mars. Our preliminary simulation results give ENA intensity images similar to the ones obtained from ASPERA- 3/NPD observations, although there are still discrepancies due to uncertainties in the current exospheric models.
