    • DAWN GRAND MAP CERES HYDROGEN MAP V1.0

    Metadata Updated: December 6, 2023

    A global map of the concentration of hydrogen within the regolith of asteroid 1 Ceres on twenty-degree quasi-equal-area pixels is provided. Hydrogen concentrations were determined from thermal+epithermal neutron counting data acquired by the NASA Dawn mission's Gamma Ray and Neutron Detector (GRaND) while in low altitude mapping orbit, about 385 km from Ceres' surface (about 0.8 body radii altitude). The concentrations are representative of Ceres's bulk regolith to depths up to a few decimeters with a spatial resolution of about 600-km full-width-at-half-maximum of arc length on the surface. The methods used to determine hydrogen concentration are described by PRETTYMANETAL2017.
