What you'll do

Space agencies around the world are investing heavily into lunar exploration with the aim of establishing the Moon as a platform for humanity to become a multi-planetary species. Lunar exploration missions are furthering key scientific objectives around surviving and prospering in space as well as providing information on the origins of life as a whole. The lunar roadmap foresees in-situ resource utilisation on the Moon to establish a permanent human presence during the 2030s, as well as using the Moon as a “refuelling station” for further space exploration to Mars and beyond.

As part of the investment into lunar exploration, European Space Agency (ESA) created the Moonlight programme – a private-public partnership. Moonlight will develop new communications and navigation capabilities and services that will be provided to missions on and around the Moon through the launch of dedicated infrastructure.
