It could be the first human settlement on another planet.

European Space Agency bosses today revealed a video tour of the moon base. They hope it could be ready for humans to move in within the next 40 years. It will be made from an inflatable dome covered in lunar soil by robots to create a safe structure, and will have room for four to live and work.

ESA teamed up with architectural firm Foster + Partners in order to set the wheels in motion for a permanent human presence on Earth’s only natural satellite. Autonomous robots will be used to 3D print a cellular structure to house four people, and can offer protection from meteorites（陨石）, gamma radiation and great temperature changes. The ESA’ s human spaceflight team’s Scott Hovland said: “3D printing offers a potential means of facilitating lunar settlement with reduced supplies from Earth.”

The theory is that 90 per cent of the materials needed to build the structure already exist on the Moon, so only the robots and light-weight parts, such as inflatables（充气的）and the solid connector and entry segments（部分）, will have to be transported from Earth. These parts would be folded from a tubular

（管状的）module that can be sent by space rocket.

The shell is made up of a hollow closed cellular structure similar to foam. They say the “hollow closed-cell structure” – like that of bird bones – “provides a good combination of strength and weight.” Xavier De Kestelier of Foster + Partners Specialist Modelling Group said; “As a practice, we are used to designing for extreme climates on Earth and exploiting the environmental benefits of using local, sustainable materials. Our lunar structure follows a similar logic.”

The raw lunar material is turned into a pulp and sprayed to form a solid block that is then used to build walls at a rate of around two meters an hour. “First, we needed to mix the simulated lunar material with magnesium oxide（氧化镁）. This turns it into ‘paper’ we can print with,” explained Monolite founder Enrico Dini.
