Developed at NASA's Glenn Research Center in Cleveland, the material could be created directly on the moon or Mars, allowing NASA to pack fewer supplies—saving weight and reducing launch costs.
To make the material, research chemical engineer Allison Christy and her team of summer interns at NASA Glenn—Tyler Klinchuch, Ethan Bilodeau and Emma Levenson—mixed a special plastic with simulated moon and Mars dust. This plastic is biodegradable and could be produced by bacteria fed with crew waste or carbon dioxide. "The plastic literally grows within the bacteria's little bodies," Christy said.
"It's really cool." The team found that incorporating simulated lunar and Martian dust particles into the plastic made it stronger and easier to process. Adding different types and amounts of dust allowed them to adjust the material's properties. The gray image shows sample material manufactured using mock moon dust, while the reddish image shows material made with mock Mars dust.
The material could be used to manufacture equipment for future moon or Mars habitats, like structural brackets, wrenches or chairs. By potentially enabling on-demand, fully recyclable fabrication with lunar surface material, it could help advance NASA's objective of a permanent moon base by reducing resupply needs and allowing crews to build and repair essential equipment on-site. "You can't just bring everything with you to the moon or Mars," Christy said.
"If something breaks, you have to find a way to fix it with what you have. This is a very versatile material, which is a huge benefit." The team hopes to analyze whether the material could also be used outside in the harsh environments of the lunar or Martian surfaces. The material is undergoing testing in Glenn's Lunar Environment Structural Test Rig to see how it holds up in extreme temperatures.
Several samples are also slated to launch aboard the upcoming Materials International Space Station Experiment 23 (MISSE-23) mission and will be exposed to intense conditions outside the station.
