Abstract Planning a safe and productive human space exploration mission involves a dual approach addressing both the health of the vehicle and the crew. The goal of this study was to develop a quantitative model of astronaut health during long-duration space flight and a medical supply demand model in support of such missions. The model provides two outputs, Alpha h and Mass of Medical Consumables (MMC), for each set of input parameters. Alpha h is an estimate of total crew health and is displayed as a percentage. MMC is a measure of medical consumables expended during the mission and is displayed in units of kilograms. We have demonstrated that Alpha h is a function of three scaling parameters, the type of mission, duration of mission, and gender mix of the crew. The type of mission and gender of crew are linked to radiation fatality data published by NASA. Mission duration is incorporated into the model with predicted incidence of illness and injury data published on US Navy submarine crews. MMC increases non-linearly with the number of crew, the duration of the mission and the distance of the mission away from Earth. This article describes the relationships between these parameters and discusses implications for future crewed space missions.

    Highlights We created a model to assist in planning a safe and productive human space mission. We demonstrated that Alpha h is a function of the type and duration of mission. We demonstrated that MMC increases with crew size, duration, and mission distance.
