The realization of a sustainable manned Mars habitation mission cannot be achieved using conventional methods because the mission conditions, such as available resources, hazards, and journey time, differ significantly from those of previous manned space missions. Therefore, construction of a sustainable interplanetary transportation network, a Mars-based resource management system, and hazard management system should be considered. In addition, the development of key advanced technologies is very important. Hence, the logistics system constructed in this study considers not only mission requirements such as human transfer and stay times but also the available technology and required safety levels. Using simulations of the logistics system, we calculated the optimal stay cycle to minimize the initial mass in low Earth orbit. As a result, the effects of the limitation on the stay time and the superiority of stop-over and cycler trajectories with respect to the requirements of the stay cycle are quantitatively declared.
