Maximal area densities are given in µg/cm2 for each element at the top of each map. The scatter is shown in the Sa, which can be used as an indicator of thickness and density of the sample.

    A new article suggests NASA and others hunting for proof of Martian biology in the form of ‘microfossils’ could use the element vanadium in combination with Raman spectroscopy to confirm traces of extraterrestrial life...
