In a quiet laboratory in Louisiana, researchers are developing technologies that could transform the Moon from a distant destination into a place where humans live and work – without needing to haul every brick, pipe and tool from Earth, potentially reducing dependence on costly shipments from the planet.
As part of NASA’s Artemis programme, which aims to establish a sustained human presence on the lunar surface, scientists are turning their attention to the Moon’s most abundant and unpromising resource: its dust.
A team at Louisiana State University (LSU), including assistant professor of engineering Chris Marvel and PhD student Emma McCarthy, is exploring how lunar regolith – the fine, powdery material covering the Moon – could be processed into construction materials and manufacturing feedstock.
“The long-term idea is that, instead of bringing every material needed from Earth, we could potentially use materials already on the Moon for things like construction or manufacturing,” McCarthy said.
Marvel envisions small manufacturing plants on the lunar surface capable of grinding regolith and combining it with other local resources. “If we were going to do this on the Moon, we would build a small manufacturing plant there which we think is possible, and would then have this essentially infinite resource that we could use,” he added. “We just need to get these plants built.”
A key technical hurdle has been developing materials that can withstand the extreme conditions of processing lunar dust. Molten regolith is highly corrosive and requires temperatures exceeding 2,900 degrees Fahrenheit that is roughly six times hotter than a typical kitchen oven.
At NASA Glenn in Cleveland, researchers including Dr Jamesa Stokes and Dr Kevin Yu created and tested a new substance designed to resist corrosion from molten Moon dirt. The material, incorporating scandium oxide, offers a more affordable alternative to precious metals like platinum traditionally used in such high-temperature environments.
“It’s actually a very cool-looking powder; it goes in pink, almost like strawberry milk,” Dr Yu said, describing the colour-changing indicator that signals when the reaction has completed, shifting to a light beige or tan.
Laboratory tests showed the new material holds up well under the punishing conditions needed for resource extraction. It is also lighter, less dense, and provides superior heat insulation compared with current state-of-the-art coatings, opening potential applications beyond space—including protective coatings for jet engine components that endure similarly intense heat.
The insights could shape NASA’s designs for future systems to extract metals and other resources from Moon rocks, with the new substance suitable for pipes, basins, and containment vessels handling molten regolith.
Dr Stokes emphasized the foundational role of materials science in ambitious exploration goals. “You can have the best idea in the world for a structure or a vehicle, but if you don’t have the materials that have the right properties to make your vision come true, it’s not going to succeed, no matter how well you design it.”
Their progress marks an important step toward making long-duration lunar operations economically and logistically viable.
While timelines for deploying such technologies on the Moon remain uncertain, the researchers continue refining the material to improve purity and reduce production costs.
