Lunar Construction: Bacteria-Based Innovation
In a groundbreaking advancement, researchers at the Indian Institute of Science (IISc) have developed a bacteria-based technique to repair bricks, aiming to create sustainable lunar habitats. This approach could revolutionize how we approach space construction, particularly with NASA’s Artemis programme—designed to establish a permanent human presence on the moon—highlighting the necessity for innovative construction solutions.
Utilizing Lunar Regolith
Astronauts will need to embrace the abundant lunar soil, known as ‘regolith,’ instead of transporting earth-based materials. IISc’s researchers have harnessed Sporosarcina pasteurii, a bacterium, to manufacture bricks from lunar and Martian soil simulants, addressing both the economic and logistical challenges of lunar construction.
Why Sintering?
Sintering, a traditional method of heating compacted soil mixtures, provides bricks with the high strength necessary for conventional housing. However, as IISc Associate Professor Aloke Kumar mentions, while scalable, sintered bricks aren’t suitable for the moon due to extreme temperature fluctuations and exposure to harsh conditions.
Addressing Lunar Challenges
The lunar environment’s drastic temperature shifts and constant bombardment by solar radiation and micrometeorites can give rise to cracks in sintered bricks, potentially compromising structural integrity. Thus, researchers devised a bacteria-inclusive solution to reinforce these bricks.
“These conditions necessitate innovative solutions to ensure the durability of lunar structures,” explains Koushik Viswanathan, co-author of the study. Introducing sporocellular defects and applying a slurry of Sporosarcina pasteurii and lunar soil simulants effectively binds the material, mitigating the brittleness that typically besets sintered bricks.
Testing and Future Prospects
The reinforced bricks have shown resilience across a broad temperature range, promising better adaptability to lunar conditions. Plans are underway for IISc researchers to send Sporosarcina pasteurii into space with India’s Gaganyaan mission to further study biodurable construction in microgravity.
