Abstract
CRUX is a suite of modular geophysical and borehole instruments combined with a display and decision support system (Mapper/DSS) to characterize regolith resources, surface conditions, and geotechnical properties. CRUX is a NASA-funded Technology Maturation Program effort to provide enabling technology for Lunar and Planetary Surface Operations (LPSO). The Mapper/DSS uses data fusion methods with CRUX instruments, and other available data and models, to provide information about regolith properties needed for LPSO that cannot be determined otherwise. We demonstrate how the data fusion method might be applied to characterize the form of hydrogen and its 3D distribution using a Borehole Neutron Probe and Thermal Evolved Gas Analyzer data as a function of depth to help interpret Surface Neutron Probe data. Information from other CRUX instruments, along with physical models, improves the accuracy of hydrogen distribution characterization, enabling information products for operational decision-making.
