To learn how to build with moon dust, researchers are turning to volcanic powder here on Earth.

Several countries are planning lunar missions over the next decade, and some may choose to send human settlements to the moon's surface.

Many programs have recently tested out the habitability of lunar bases. In May 2018, Chinese student volunteers in Beijing completed a one-year test living in a simulated lunar lab. In October 2017, the International MoonBase Summit (IMS) convened in Hawaii to discuss building a mock structure to examine how a human settlement on the moon would work. And for two weeks in August 2017, six mock astronauts lived inside a simulated moon base in Poland. [This NASA Video of the Moon's Landmarks Is Simply Amazing]

But how would you build a base in the first place?

The rough, fine dust that covers the moon's surface, known as regolith, may have structural potential. And researchers with the European Space Agency (ESA) recently announced their "lunar masonry" studies to see how it would fare.

Their idea is to try to break reliance on earthy construction materials, according to an Aug. 20 statement issued by ESA.

To get an idea of how one might make bricks from moon dust, researchers analyzed volcanic material near Cologne, Germany, where eruptions happened 45 million years ago. This volcanic powder is a good match for what lunar dust might be like, according to ESA officials, because the moon's surface is made of basaltic material called silicates that are common near planetary volcanoes.

"The moon and Earth share a common geological history, and it is not difficult to find material similar to that found on the moon in the remnants of lava flows," Aidan Cowley, ESA's science adviser, said in the statement.

The moon dust substitute is named "EAC-1" after ESA's European Astronaut Centre, whose researchers found that it was a good match with the real deal.

And lunar dust may also support human missions in another way, too:

"One of the great things about the lunar soil is that 40 percent of it is made up of oxygen," Cowley said. Researchers on another EAC project are studying how to extract the oxygen within moon dust so that astronauts may extend their stays on the moon.
