Satellite miniaturization and sinking costs of manu-facturing and launches are bringing Moon missions in the focus of many space companies and agencies. However, achieving the desired data rates on CubeSats over long ranges is proving increasingly challenging with traditional radio-frequency communication systems. Free-space optical (FSO) communications offer a compact, light, and low-power alternative with higher data throughput and fewer limitations (e.g., fewer governmental regulations, channel interference, eavesdropping...). Based on its long heritage of laser communications and new-space tech-nology, the German Aerospace Center (DLR) is investigating SelenIRIS-a miniaturized terminal for Moon-Earth optical data transmissions-for its OSIRIS program. This paper will analyze the necessary adaptations that are required to transfer the technology from the flight-proven low Earth orbit terminals like OSIRIS4CubeSat (O4C) [1] to a concept mission in Lunar orbit.
