With all the talk about manned missions to Mars by the 2030s, its easy to overlook another major proposal for the next great leap. In recent years, the European Space Agency has been quite vocal about its plan to go back to the Moon by the 2020s. More importantly, they have spoken often about their plans to construct a moon base, one which would serve as a staging platform for future missions to Mars and beyond.

These plans were detailed at a recent international symposium that took place on Dec. 15th at the the European Space Research and Technology Center in Noordwijk, Netherlands. During the symposium, which was titled “Moon 2020-2030 – A New Era of Coordinated Human and Robotic Exploration”, the new Director General of the ESA – Jan Woerner – articulated his agency’s vision.

The purpose of the symposium – which saw 200 scientists and experts coming together to discuss plans and missions for the next decade – was to outline common goals for lunar exploration, and draft methods on how these can be achieved cooperatively.

In the past, Woerner has expressed his interest in a base on the Moon that would act as a sort of successor to the International Space Station. Looking ahead, he envisions how an international community would live and perform research in this environment, which would be constructed using robotic workers, 3D printing techniques, and in-situ resources utilization.

Going forward, the plan calls for a series of manned missions to the Moon beginning in the 2020s, which would involve robot workers paving the way for human explorers to land later. These robots would likely be controlled through telepresence, and would combine lunar regolith with magnesium oxide and a binding salt to print out the shield walls of the habitat.

At present, the plan is for the base to be built in southern polar region, which exists in a near-state of perpetual twilight. Whether or not this will serve as a suitable location will be the subject of the upcoming Lunar Polar Sample Return mission – a joint effort between the ESA and Roscosmos that will involve sending a robotic probe to the Moon’s South Pole-Aitken Basin by 2020 to retrieve samples of ice.
