Différentes observations de l’atmosphère martienne font état de son échappement vers l’espace. Parmi les mécanismes d’échappement identifiés comme potentiellement à l’origine de cet échappement, le criblage atmosphérique est considéré comme un processus minoritaire de nos jours. Le taux d’échappement par criblage étant difficilement directement mesurable, les estimations actuelles reposent essentiellement sur l’utilisation de modèles analytiques ou numériques mais varient fortement d’un modèle à l’autre en raison de l’absence d’une mesure précise du flux de particules impactant l’atmosphère et à l’origine du criblage atmosphérique. Le but principal de ma thèse a été d’étudier les données obtenues par les instruments du satellite « Mars Atmo...
