Given the absence of an orbital system to communicate from the far side of the Moon, it is likely that such a system shall be needed in the near future with the continued interest in lunar exploration and utilization. A strategy for a long-term libration orbit at the Earth-Moon L2 point is developed. This strategy allows for uninterrupted two-way communication between the Earth and the far side of the Moon and vice versa while also maintaining low fuel costs, thus increasing the duration of possible missions. A scenario was created in STK that created such an orbit. The results of the scenario predict a total station keeping delta-V cost of only 3.23 m/s for a satellite to stay in the vicinity of the EML2 point for five years.
