Masses ranging from 1.0 mg to 1 016 mg of the European Astronaut Centre lunar regolith simulant 1 (EAC - 1A) were placed on a chemically polished aluminium disc and the total hemispherical absorptivit

The value Q R of transferred heat power is calculated from the temperature drop (between T A and T B) in steady state on the previously calibrated thermal resistor.
