Scientific paper

The Dynamic Albedo of Neutrons (DAN) instrument, a neutron scattering instrument currently being constructed by IKI, is a component of the science payload of the 2009 Mars Science Laboratory (MSL) mission. Based on simulations using the Monte-Carlo N-Particle Extended (MCNPX) particle physics code, DAN is able to measure bulk water content and to detect variations in water concentration up to ˜50 cm beneath the ground surface, assuming perfect detector performance. Data from DAN, combined with measurements from other instruments on MSL, allow derivation of profiles of water content to a depth of ˜15 cm.
