The Hyperspectral and Stereo Capabilities of HYPSOS on the Moon – Acquisition Simulation

The 3D mapping derived by stereo imaging and the spectral information provide data for the full understanding of the observed features both in geometrical and compositional terms. HYPSOS (Hyperspectral Stereo Observing System) [1] is a novel concept of hyperspectral-stereo camera that combines the 3D information attainable by couple of stereo images with the fine spectral sampling of a spectrometer. Thanks to HYPSOS, the morphology of any feature analyzed through the 3D images, will be related to the composition of the same feature, through the hyperspectral data. Hence, the new instrument will avoid typical problems encountered when trying to combine data from two different instruments. The HYPSOS concept has been already realized in laboratory and a possible mission on the Moon is an interesting scenario. Although Moon morphologies and geological units were studied from the dawn of planetary exploration, the origin and evolution of many surface features are not completely known. The integrated information of the elevation and spectral data could be considered very successful for the extraction of new insights at a global scale. This new instrument concept can extend the capacity of discrimination of different landforms (e.g sinuous rilles, impact craters, volcanic features) improving the geological mapping of the surfaces, and the history of its evolution. To test the potentialities of HYPSOS operating in a possible mission scenario on the Moon, a virtual environment has been considered. In particular, ray tracing techniques can be used to generate digitally-rendered images that are consistent with a specific observation geometry (e.g LROC orbit [2]) and where the global topography of the Moon defines the scientific target. Taking advantage of the AIS simulator [3], a large dataset of synthetic stereo hypercubes will be provided in order to test the performance of the hyperspectral stereo camera. In particular, it can be verified how different spectral and/or spatial details can be resolved with HYPSOS operating on a possible Moon mission scenario.
