The next global strategic priority in space missions is a stable access to the Moon. Over the last few years several studies and discoveries have pushed the space agencies and companies worldwide to numerous feasibility studies to realize permanent infrastructures and assets in cis-lunar environment and on its surface. NASA’s Artemis program to take humans back to the Moon in this decade is a huge driving force in the generation of an economically sustainable path for lunar exploration and resource exploitation, aiming to create a reference point to reach furthest celestial bodies of high interest like Mars. In this framework, Thales Alenia Space is conducting the feasibility study of the Lunar Communications and Navigation Services (LCNS) within European Space Agency's (ESA) Moonlight initiative that will support Artemis space program.
