Abstract (summary)
Near-infrared (NIR; 1-4 um) imaging spectroscopy of Mars has proven itself to be critical in the identification and mapping of the distribution of aqueous alteration products on Mars, and has also been a key player in the process of Landing Site Selection for MSL. In this paper, we argue that increasing the spatial resolution to the meter scale from orbit, and mounting a NIR imaging spectrometer or hyperspectral imager on a rover will result in significant scientific benefits including 1) the identification of new hydrous minerals, 2) setting better constraints of spatial and stratigraphic distribution of the hydrous minerals within outcrops, 3) characterization of bed and unit boundaries and transitions, and 4) identification and analysis of smaller features apparent at MOC and HiRISE scales. In addition to improving the scientific return of both orbital and rover missions, high spatial resolution NIR imaging spectrometers will be critical in the traverse selection, operations, and sample acquisition of future rover missions.
