The Moon is a logical next step for human exploration beyond low-Earth orbit. The lunar far side remains unexplored by landed spacecraft. From Earth-Moon L2 libration-point orbits, astronauts could operate robotic spacecraft on the lunar farside. Such orbits can also be used as transportation nodes for reaching more distant destinations. We investigate low deltaV trajectories that simply loop around L2, spending nearly two weeks over the lunar back side. Also investigated are the occultation times for Earth ground stations for Lissajous orbits of different sizes, and the deltaV costs to reach and return from such orbits.
