DAWN GRAND MAP VESTA HYDROGEN ABUNDANCE V1.0
Listed in NASA Data Portal
A global map of the abundance of hydrogen in micrograms/g within the regolith of asteroid 4 Vesta is provided for two-degree equal-angle pixels.
Description
Hydrogen abundances were determined from epithermal neutron counting data acquired by the NASA Dawn mission's Gamma Ray and Neutron Detector (GRaND) while in low altitude mapping orbit, about 210 km from Vesta's surface. The abundances are representative of Vesta's bulk regolith composition to depths of a few decimeters with a spatial resolution of about 300-km full-width-at-half-maximum of arc length on the surface.
The methods used to determine hydrogen abunance are described by PRETTYMANETAL2012.
