Abstract

The laser-induced breakdown spectroscopy (LIBS) instrument ChemCam onboard NASA's Curiosity rover measures the chemical composition of Martian targets at remote distances. It ablates material with its laser and can therefore also measure depth profiles when targeting multiple times the same position. We included these so calles shot-to-shot trends as a third dimension in the ChemCam dataset and applied a tensor decomposition technique to it. With this method it is possible to detect correlations of elemental abundances with depth among multiple targets.
