The Dynamic Albedo of Neutrons instrument (DAN) onboard the Mars Science Laboratory (MSL) uses 3He proportional counters to detect neutrons escaping the martian surface. This neutron leakage flux can be used to estimate the amount of hydrogen in the

The primary objective of the Dynamic Albedo of Neutrons (DAN) experiment on board the Mars Science Laboratory (MSL) rover Curiosity is to assess the hydrogen content as the rover traverses the Martian surface. Because hydrogen is a light element, it
