Bengaluru Soil Bacteria Could Help Build Bricks on Mars: Study
The possibility of human settlement on Mars has been a topic of interest for scientists and space enthusiasts alike. However, one of the major challenges in establishing a human settlement on the red planet is the lack of infrastructure and construction materials. Transporting construction materials from Earth to Mars is a costly and logistically challenging endeavor. But what if we could use the Martian soil itself to build structures? A recent study published in PLOS One suggests that a soil bacterium discovered in Bengaluru could hold the key to building bricks on Mars.
The study, conducted by researchers from the Indian Institute of Science (IISc), Indian Institute of Science Education and Research (IISER) Kolkata, and ISRO astronaut Shubhanshu Shukla, found that a specific type of soil bacterium can bind Martian soil into strong bricks. The research team used a bacterium called Sporosarcina pasteurii, which is commonly found in soil and is known for its ability to produce calcite, a natural cement.
The researchers used a simulated Martian soil, which is similar in composition to the soil found on Mars, and mixed it with the Sporosarcina pasteurii bacterium. They then added a nutrient solution that stimulated the growth of the bacteria, which in turn produced calcite. The calcite acted as a binding agent, holding the Martian soil particles together and forming a strong brick-like structure.
The results of the study were impressive, with the bricks formed using the bacterium showing a compressive strength of up to 50 MPa, which is comparable to that of regular concrete. The researchers also found that the bricks were resistant to heat and radiation, making them suitable for use in the harsh Martian environment.
The implications of this study are significant, as it could potentially provide a solution to the problem of building infrastructure on Mars. By using the Martian soil itself to build structures, we could reduce the need to transport construction materials from Earth, which would not only save on costs but also reduce the risk of contamination and other logistical challenges.
The study also highlights the potential of using microbes to construct buildings and other structures. Microbes have been used in construction for centuries, with examples including the use of bacteria to produce natural cement and the use of fungi to create sustainable building materials. However, the use of microbes to build structures on other planets is a relatively new area of research, and this study demonstrates the potential of this approach.
ISRO astronaut Shubhanshu Shukla, who was part of the research team, noted that the study has significant implications for future Mars missions. “The use of Martian soil to build structures could be a game-changer for future Mars missions,” he said. “It could provide a sustainable and cost-effective solution for building infrastructure on the red planet.”
The study also highlights the importance of interdisciplinary research, with the team consisting of experts from a range of fields, including microbiology, materials science, and aerospace engineering. The collaboration between IISc, IISER Kolkata, and ISRO demonstrates the potential of Indian research institutions to contribute to cutting-edge research in the field of space exploration.
In conclusion, the discovery of a soil bacterium in Bengaluru that can help build bricks on Mars is a significant breakthrough in the field of space exploration. The study demonstrates the potential of using microbes to construct buildings and other structures, and highlights the importance of interdisciplinary research. As we continue to explore the possibilities of human settlement on Mars, this study provides a promising solution to one of the major challenges facing us.
