A reference study on constructing human exploration station at earth-moon libration point

On Sep 2011, International Space Exploration Coordination Group (1SECG) released a reference mission scenario ultimately conducting human exploration to Mars. On the course of attaining the goal, several preparatory exploration missions must be required. One of the most promising intermediate destinations is Earth-Moon Lagrange Points (EMLs) which have unique characteristic of gravitational equilibrium. EML2, among the 5 EMLs, is considered as the most superior position not only as the staging station for further solar system exploration but as the base camp for lunar far side exploration. This paper outlines the logistics scenario for the EML2 station to clarify the affordability in constructing and maintaining such the station. Assuming the existing and developing transportation systems, several patterns of logistics scenario are presented. Also, this paper suggests the possibility of the transportation efficiency improvements using stable manifold and swing-by characteristics.
