The objective of the project “Study of the degradation of biosignatures under Martian irradiation” is to evaluate the effect of irradiation of galactic cosmic rays during several billion years on fossiliferous Mars analog rocks and the protective effect of different minerals on molecular biosignatures. This is highly relevant for the ExoMars mission to estimate the depth at which various biosignatures of interest may be preserved, depending on the mineral matrix.  These samples will be exposed to proton irradiation at the CEMHTI Pelletron (CNRS, Orléans), where the PhD student will have direct access to the accelerator.
