Location, location, location
Currently, stakeholders plan to build Moon Village near the lunar south pole. In particular, they want to target somewhere close to the rim of Shackleton Crater, which boasts areas that are almost perpetually bathed in sunlight — ideal because it provides an ample source of energy via the tried-and-true technology of solar panels.
In addition to copious amounts of available sunlight, at about 2.5 miles (4 kilometers) deep, the floor of Shackleton Crater is constantly cloaked in shadow. This means it’s the perfect place to hide valuable, sunlight-sensitive volatile resources like water-ice. Such a find nearby could provide residents of Moon Village with drinking water, breathable air, and a potential source of rocket fuel, as long as we have the means to unlock it.
Designing a Moon base
According to the plan, Moon Village will be built in incremental steps. First, individual landers will descend to the lunar surface near Shackleton Crater, at which point they’ll each deploy inflatable modules. These modules, which are expected to be up to four-stories tall, would eventually serve as workspaces, residential areas, scientific labs, industrial sites, and environmental habitats.
The inflatable modules, however, cannot effectively shield humans from harmful radiation, temperature swings, or micrometeorite strikes. So, the ESA and MVA are currently working with private industries to design robots that can 3D print a protective shell around each structure using readily available regolith taken from the lunar surface.
Researchers estimate it should take a pair of such robots about three Earth months to construct a solid dome around an inflatable module. And as more of these habitats are built, they will be networked together through a series of pressurized walkways connected to airlocks at each module.
Making it happen
Europe, NASA, and even China are all currently working toward the goal of establishing a long-term presence on the Moon. But the reality is that no matter who gets credit for building the first reliable lunar settlement, it will likely one day morph into a massive international collaboration unlike anything humans have ever seen.
With the ESA and MVA spending time thoughtfully considering the best approaches for building an expandable, adaptable, and most of all permanent lunar base, Moon Village is definitely worth keeping an eye on.
