Hassell and the European Space Agency have unveiled their Lunar Habitat Master Plan, a conceptual design for a scalable moon base.
Commissioned by ESA’s Discovery programme and designed by architectural firm Hassell, the ideas will guide the agency’s technological development of such structures, so it can solve some of the issues moon dwellers could face in a future where research, exploration, tourism and prospecting may all form part of a lunar economy.
“More people on the moon in a sustainable way. This is a good picture to have in mind,” says ESA advanced manufacturing engineer Advenit Makaya, who was involved in the design process. The concept aims to address problems that might arise from having people on the lunar surface for extended periods. This includes protecting astronauts from the harsh environment, such as radiation and dust, and dealing with extreme temperatures, lack of water, oxygen and power.
The habitat is designed around a series of inflatable pods that would make minimal contact with the surface, reducing issues with abrasive dust. These would then be protected by a shell made of blocks, 3D printed using lunar soil, known as regolith, that can be interlocked into place over the pods to absorb radiation. We might also be able to get water or oxygen from the regolith. And to mitigate temperature fluctuations, and maximise solar power efficiency, the base would be built on the edge of Shackleton crater at the moon’s south pole where it would face the sun for longer.
Both ESA and Hassell admit their design is some way from becoming a reality, but flexibility is at the heart of it. “Is it a case of running before we can walk? I don’t think so. These things take a long, long time to plan,” says Xavier De Kestelier, the global head of design for Hassell and the lead architect on the project. “We need to keep on exploring the science.”
