Understanding the chemical evolution of organic molecules at the surface of Mars is of major interest in order to drive and discuss past, present and future in situ analyses aiming to determine if Mars had ever seen life's emergence. Through Mars' history, organic molecules could have been produced by multiple pathways (either abiotic, prebiotic or biological) or delivered by the meteoritic incoming flow. But after Mars lost its magnetic field and then the main part of its atmosphere, ultraviolet radiation, oxidants, solar particles and cosmic rays, can generate physico-chemical processes that may affect organic molecules. What is the evolution of organic molecules potentially present at the surface? This thesis brings some answers to this ...
