IMPLICATIONS OF SCALING VISIBLE AND NEAR IR SPECTROSCOPIC DATA ON DETECTION OF MINERALOGY: A CASE STUDY IN RIO TINTO, SPAIN
We use the Rio Tinto, in southwestern Spain, as proving grounds for our study into the implications of scaling between several spectral and spatial resolutions. The Rio Tinto is an important Martian analog for its acidic conditions leading to iron and sulfate mineralogy and an associated complex biological system. Techniques learned when combining hyperspectral data from a point spectrometer used in the field with aerial data over the Rio Tinto (captured by Hymap) are applicable to future reconnaissance and exploration mission to Mars. We are determining spatial and spectral scales at which critical indicators of habitability are diminished and lost. This study yields important lessons to apply to future exploration missions integrating orbital spectrometers with rovers/landers.
