A pulsed neutron gamma-ray system for Mars rover missions

A pulsed neutron gamma-ray system (PNGS) can be used to determine the subsurface planetary geochemistry on rover missions to Mars and other planetary bodies. These data can be used to unravel the history of formation of biogenic materials, characterize the climate, explore the geology and characterize the radiation environment. We have performed feasibility studies for a pulsed neutron/gamma-ray system (PNGS) to operate on a Mars Science Laboratory (MSL) type rover. It has been developed to meet the MSL rover mission constraints on mass and power limitations, temperature and radiation effects, and reliable operation for long periods of time
