Trace Element Calibrations using the ChemCam InstrumentOnboard the Curiosity rover, the ChemCam suite has a laser induced breakdown spectrometer (LIBS) that allows to quantify elemental abundances of rocks and soils at distance (1.6 - 7 m from the rover) at a micrometer scale (350 - 550 µm). Using a large dataset from Los Alamos National Laboratory (LANL), we re-calibrated Li, Rb, Sr, and Ba and quantified for the first time Cu using univariate calibrations. Li, Rb, Sr, Ba and Cu concentrations can now be measured in all materials analyzed by LIBS since the beginning of Curiosity journey.
