This protocol presents comprehensive technical and operational guidelines for managing human death in long-term Martian colonies. It addresses biological safety, resource efficiency, psychological support, and cultural considerations within the extreme constraints of the Martian environment. The document includes detailed specifications for cremation systems (55 kWh, 1400°C), ash processing and nutrient recycling (96% efficiency), cemetery design, a dual ceremonial system (mandatory ecumenical + optional religious), and structured psychological support protocols. All values are based on established scientific principles but require experimental validation.
