Scientific paper

In the last few years the OMEGA instrument on the ESA Mars Express mission detected diverse phyllosilicates on Mars’ various locations. These deposits are important to improve our knowledge of the planet evolution, since they formed on Mars in the Noachian period, when moderate pH and large amount of available water occurred. On the same Mars Express mission another spectrometer is flying: the Planetary Fourier Spectrometer (PFS), measuring the Mars radiation in the spectral range between 1 and 50 microns. We used the PFS data, together with a surface-atmosphere separation algorithm and a linear deconvolution method to infer the surface composition on the same Mars regions where OMEGA detected the phyllosilicates, confirming their findings. The spectral library used for the surface linear deconvolution is the Berlin Emissivity Database (BED), containing emissivity spectra in the [1-50] µm spectral region, measured in the Planetary Emissivity Laboratory (PEL) at DLR in Berlin.
