Descripción del proyecto Amino acids and the reference nucleobases for RNA and DNA can be formed in space ice under high energy, vacuum ultraviolet (VUV) irradiation. This statement is based on twenty years of laboratory research and has profound implications in the understanding of the emergence of life in the Cosmos, the universality of the processes involved and the compatibility of life forms across the Universe. However, this laboratory work still needs to be confronted with actual, on-field measurements. Promising data have been obtained through in-situ techniques: the analysis of carbonaceous chondrites such as the Murchinson meteorite or the detection of Glycine in the coma of comet 67P/Churyumov-Gerasimenko. Unfortunately, neither of these techniques suits well a systematic investigation. Meteorites reaching the Earth surface represent a reduced and biased subset and contamination by Earth-based amino acids needs to be carefully controlled. Space probes such as Rosetta are very costly and limited in scope given the constraints in space navigation. Thus, it is crucial to develop remote detection techniques to carry out a comprehensive study of the distribution of amino acids within the Solar System, their relative abundances and their enantiomeric imbalance. According to recent estimates, this is possible at VUV wavelengths for optically active amino acids such as the very abundant alanine. The interaction between VUV radiation and optically active amino acids in space bodies is yet poorly studied. The formation of crystallites and complex structures, the interaction between the various molecules, the dependence on the VUV photon energy, polarization and flux needs to be quantified, prior to any attempt of remote detection in the Solar System. This project aims to carry such in-depth study and develop a laboratory prototype of the instrument to make, at the least, alanine remote detection feasible by a small probe navigating the asteroids belt.
