description |
International audience Mudstones collected on the Yellowknife Bay site in Gale crater by the Curiosity rover, were analyzed with the Sample Analysis at Mars (SAM) chemical laboratory with the aim (among others) to detect and identify organic molecules in the Martian reglith [1]. The pyrolysis (to 900°C)-gas chromatography-mass spectrometry (Pyro-GCMS) analytical mode was systematically used to reach that goal. It revealed the existence of complex interactions between compounds present in the soil sample (e.g. oxychlorines [2]) and internal components of the SAM experiment (e.g. derivatization reactant) resulting in signals complex to interpret [3].By comparing these results with those obtained for the other Mars samples analysed with SAM, and by carefully identifying, from laboratory work, the possible SAM internal contributions to the organic molecules detected [4], chlorobenzene has already been identified as mainly originating from organics present in the mudstone [5]. Since this discovery, we did additional studies of the chromatograms that reveal the presence of dichlorobenzene originating from an organic source endogenous to the sample. Even if the exact original source of these organic molecules cannot be strictly identified, the detection of several chlorinated aromatic molecules suggests the presence of a significant amount of aromatized materials which are in an oxidized state involving oxygen in the mudstone. We present here the corresponding results and the implication it can have on the origin of these organic materials.References: [1] Mahaffy, P. et al. (2012) Space Sci Rev, 170, 401-478.
