Hyperspectral and high-resolution image data from the Mars Reconnaissance Orbiter allow us to link mineralogy to morphology and infer martian environments. Prof. Gilmore’s groups examines visible/near-infrared data from orbit and in the laboratory to better understand Mars history. Laboratory work allows us to better understand the relationship between real materials and their spectral signatures. We have published the first paper on hydrous carbonates relevant to Mars, including synthesizing low-temperature minerals and collecting spectra new to the literature. Current work uses a Mars chamber built in house to create, evaporate and collect spectra of Mars analogue brines under Mars conditions. Our group has also tested and applied automated image processing techniques useful for hyperspectral data analysis using a combination of laboratory, orbiter and field-derived spectra.
