Planetary Data Analysis HRSC/PFS/OMEGA/CRISM/HiRISE

This research project concerns the study of the surface and the atmosphere of Mars by several imaging and spectroscopy techniques in order to characterize these environments. We use a approach of quantitative geomorphology from imaging data, an approach of determining the surface properties by using hyperspectral and high resolution spectroscopic data. The specificity of our team concerns the study of glacial, periglacial and volcanic processes of Red Planet.

Imaging: Instruments HRSC (Mars Express/ESA) et HiRISE (Mars Reconnaissance Orbiter/NASA)

The high resolution imaging from the very recent images of Mars missions attest to the existence of a range of models from a permanent frozen ground ice-rich to middle and high latitudes of an age less than 10 Million years. These models are comparable in size and morphology to those found in Siberia. The objective of this program is a study of the influence of global warming on the conditions of formation of these models by a comparative approach Earth / Mars. The originality of the comparative approach Earth / Mars is the study of certain processes under conditions of different temperature and pressures to better constrain their origin. Specific processes to Mars, such as spiders and the associated jets are studied by these imaging techniques to characterize their morphological characteristics and their temporal evolutions.

Hyperspectral Imaging: Instruments OMEGA (Mars Express/ESA) et CRISM (Mars Reconnaissance Orbiter/NASA)

Identification of the components on the surface of Mars (ice, minerals) and their properties (grain size, surface roughness) are essential constraints for understanding of periglacial processes.

This project involves the development of techniques for analyzing spectral imaging visible and near infrared of instruments OMEGA and CRISM. Techniques, advanced signal processing and inversion of radiative transfer are studied to estimate the parameters of the Martian surface.

In a second step, this project concerns the interpretation of this analysis (mineralogical and chemical compositions) to provide processes for the exchange of volatile and petrological processes of volcanic formations in comparison with the Earth and Moon.

Spectroscopy: instrument PFS (Mars Express/ESA)

In addition to the spectro-imaging, our team focuses on the identification and characterization of atmospheric and surface composed, high spectral resolution.
