Synthetic Lichen Could Help Build Homes on Mars
Updated June 25, 2025
The dream of Martian colonization edges closer to reality as scientists tackle the challenge of building structures on the Red Planet. Transporting construction materials from Earth is costly and impractical,prompting researchers to explore ways to utilize Martian resources. Dr. Congrui Grace Jin at Texas A&M University may have a solution: synthetic lichen.
Jin and her team at the University of Nebraska-Lincoln are developing engineered living materials that can autonomously create building materials. Their research, funded by NASA, focuses on using Martian regolith-the loose surface material of dust, sand, and rocks-to construct habitats. this innovation promises to revolutionize extraterrestrial construction by enabling structures to be built wiht minimal resources and human intervention, crucial for establishing a enduring presence on Mars.
“We can build a synthetic community by mimicking natural lichens,” Jin said.”We’ve developed a way to build synthetic lichens to create biomaterials that glue Martian regolith particles into structures. Then, through 3D printing, a wide range of structures can be fabricated, such as buildings, houses and furniture.”
While other methods exist for binding Martian regolith, they often require significant human assistance. Microbe-mediated self-growing technology, for example, faces limitations due to the need for continuous nutrient supplies, making it arduous to implement autonomously on Mars. Jin’s team addresses this by creating a self-sufficient system that eliminates the need for external nutrients.
The synthetic lichen system pairs heterotrophic filamentous fungi with photoautotrophic diazotrophic cyanobacteria. the cyanobacteria convert carbon dioxide and dinitrogen into oxygen and organic nutrients,supporting the growth of the fungi. The fungi, in turn, bind metal ions and enhance the growth of cyanobacteria by providing water, minerals, and carbon dioxide. Both components secrete biopolymers that enhance the adhesion among Martian regolith particles, creating a consolidated building material. The system requires only Martian regolith simulant, air, light, and an inorganic liquid medium.
“The potential of this self-growing technology in enabling long-term extraterrestrial exploration and colonization is significant,” Jin stated.
What’s next
The next phase of the project involves creating regolith ink for 3D printing bio-structures, using a technique called direct ink writng. This will allow for the creation of complex and customized structures on Mars, paving the way for sustainable Martian habitats.
