Growing Homes On Mars: Texas A&M Research Pioneers Autonomous Construction Using Synthetic Lichens
College Station, TX (SPX) june 26, 2025 – The dream of inhabiting Mars is moving closer to reality thanks to groundbreaking research at Texas A&M University. Scientists are developing innovative methods for Martian construction, utilizing the planet’s resources to build habitats for future colonists.
Building The Future on The Red Planet
For decades, the idea of humans living on Mars has been a staple of science fiction. Now, with prosperous landings achieved, the focus shifts to overcoming the practical challenges of establishing a permanent presence. How do we construct buildings millions of miles from Earth without the prohibitive cost of transporting vast quantities of materials?
Dr. Congrui Grace Jin and her team at Texas A&M may have found the answer.
Synthetic Lichens: A Martian Construction Solution
The team, in collaboration with the University of Nebraska-Lincoln, has been developing bio-manufacturing techniques using engineered living materials for years. Their latest research,funded by NASA’s Innovative Advanced Concepts program and published in the “Journal of Manufacturing Science and Engineering,” focuses on a synthetic lichen system. This system autonomously creates building materials from Martian regolith – the dust, sand, and rocks that cover the planet’s surface.
This breakthrough promises to revolutionize extraterrestrial construction by enabling the creation of structures in resource-limited environments. It’s innovative answers like this that gets us closer to calling Mars ‘home’.
“We can build a synthetic community by mimicking natural lichens,” explains Jin. “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.”
The Autonomous Advantage
Previous approaches to binding Martian regolith have included magnesium-based, sulfur-based, and geopolymer methods. Though, these require significant human intervention, a scarce resource on mars.
Microbe-mediated self-growing technology has also been explored, with designs using bacterial biomineralization, ureolytic bacteria, and fungal mycelium. While promising, these methods often require a continuous supply of nutrients, again necessitating external support.
Jin’s team addresses this limitation with a fully autonomous self-growing technology that leverages the advantages of multiple species, eliminating the need for external nutrient supplies.
This system pairs heterotrophic filamentous fungi, which produce large amounts of biominerals and thrive in harsh conditions, with photoautotrophic diazotrophic cyanobacteria.
The cyanobacteria convert carbon dioxide and dinitrogen from the atmosphere into oxygen and organic nutrients, supporting the fungi’s growth and increasing carbonate ion concentration. The fungi, in turn, bind metal ions and provide water, minerals, and carbon dioxide to the cyanobacteria. This symbiotic relationship results in biopolymers that enhance adhesion and cohesion among Martian regolith particles.
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 states.
The team is now working on creating “regolith ink” for 3D printing bio-structures using direct ink writing techniques.
| Construction Method | Resource Needs | Autonomy Level |
|---|---|---|
| Magnesium/Sulfur-Based | Significant Human Assistance | Low |
| Microbe-Mediated | Continuous Nutrient Supply | Medium |
| Synthetic Lichen System | Regolith,Air,Light,Liquid Medium | High |
The Continuing Quest To Colonize Mars
The Challenges That Face Colonizing Mars Are Enormous,But Not Unsolvable. Transporting Materials Alone Presents Significant Obstacles.
According To Spacex, A Round Trip To Mars Could Cost Around $100,000 Per Ton. Thus, Utilizing In-Situ Resource Utilization (Isru) Techniques Is Critical. Isru Involves Using Resources Available On Mars, Such As Regolith And Atmospheric Gases, To Create Everything From Building Materials To Propellant.
Nasa’s Perseverance Rover Has Already Demonstrated The Feasibility of Extracting Oxygen From The Martian Atmosphere using The Moxie (Mars Oxygen In-Situ Resource Utilization Experiment) Instrument.This Success Paves the Way For Future Missions To Produce Water, Fuel, And Other Essential Resources Directly On Mars.
The Future of Martian Construction
The Development Of Autonomous Construction Methods Using Synthetic Lichens Is A Monumental Step Towards Making Lasting Martian Habitats. As Technology Advances, The Possibility Of Establishing Self-Sufficient Colonies On mars Becomes Ever Greater. Such Developments Will Not Only Support Scientific Exploration But Also Open New Frontiers For Humanity’s Future.
Did You know? The Distance Between Earth And Mars Varies Constantly. At Its Closest, Mars Is About 33.9 Million Miles Away; At Its Farthest, It’s Around 250 Million Miles. This Variation Considerably Impacts Mission Planning And Travel Times.
In 2024, Research From The University Of Central Florida Showed That Martian Soil Can Be Used As A fertilizer For Certain Plants. This Suggests That Future Colonists May Be Able To Grow Their Own Food On Mars, Further Enhancing Self-Sufficiency.
Pro Tip: When Considering Long-Term Space Travel, Radiation Shielding Is Paramount. Martian Habitats Will Need To Incorporate Materials That Protect Against Harmful Solar And Cosmic Radiation.

The Science of Synthetic Lichens: Mimicking Nature’s Architects
Synthetic lichens, a key component of the self-healing construction paradigm, take inspiration from the natural resilience of lichens. Real lichens are composite organisms, typically consisting of a fungus and a photosynthetic partner (algae or cyanobacteria), living in symbiotic harmony. Their remarkable ability to survive in harsh environments, including extreme temperature fluctuations and drought, makes them a model for advanced construction materials.
These synthetic counterparts are designed to mimic lichens’ properties,notably their ability to repair damage autonomously. This involves creating materials that can react to environmental changes and heal cracks or damage without external intervention.The submission is expected to reduce construction costs and maintenance needs considerably and improve the durability and overall lifespan of buildings and infrastructure.
