Bengaluru Soil Bacteria Could Help Build Bricks on Mars: Study
The possibility of human settlement on Mars has been a topic of interest and research for decades. One of the major challenges in establishing a human presence on the Red Planet is the construction of structures that can provide shelter and protection from the harsh Martian environment. Currently, transporting construction materials from Earth to Mars is a significant logistical challenge, and it is essential to find alternative methods to build structures on the planet. A recent study published in PLOS One has suggested that a soil bacterium discovered in Bengaluru could play a crucial role in building structures 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 the soil bacterium can bind Martian soil into strong bricks, reducing the need to transport construction materials from Earth. This breakthrough discovery has significant implications for future Mars missions and could pave the way for the establishment of a human settlement on the planet.
The researchers used a type of bacteria called Sporosarcina pasteurii, which is commonly found in soil in Bengaluru. This bacterium has the ability to produce calcite, a natural cement that can bind soil particles together, creating a strong and stable structure. The team tested the bacteria’s ability to bind Martian soil simulant, a mixture of soil and minerals that mimics the composition of Martian soil.
The results of the study showed that the bacteria were able to bind the Martian soil simulant into strong bricks, with a compressive strength of up to 50 MPa. This is comparable to the strength of regular concrete, making it a viable option for building structures on Mars. The researchers also found that the bacteria were able to survive and thrive in the Martian soil simulant, which is a crucial factor in using them for construction purposes.
The use of bacteria to bind Martian soil has several advantages over traditional construction methods. For one, it eliminates the need to transport heavy construction materials from Earth, which is a significant logistical challenge. Additionally, the bacteria can be easily transported to Mars and can thrive in the planet’s harsh environment, making them an ideal option for construction purposes.
The study’s findings have significant implications for future Mars missions. With the ability to build structures using Martian soil and bacteria, astronauts will no longer need to rely on transporting construction materials from Earth. This could significantly reduce the cost and complexity of establishing a human settlement on Mars.
ISRO astronaut Shubhanshu Shukla, who was part of the research team, said that the discovery of the soil bacterium’s ability to bind Martian soil is a significant breakthrough. “This study has shown that it is possible to use bacteria to bind Martian soil into strong bricks, which could be used to build structures on the planet,” he said. “This is a significant step forward in our efforts to establish a human settlement on Mars.”
The researchers are now planning to conduct further studies to test the bacteria’s ability to bind Martian soil in different conditions. They also plan to explore the use of other types of bacteria that can produce different types of binding agents, which could be used to create a variety of structures on Mars.
In conclusion, the discovery of the Bengaluru soil bacterium’s ability to bind Martian soil into strong bricks is a significant breakthrough in the field of space exploration. The use of bacteria to build structures on Mars could revolutionize the way we approach construction on the planet and could pave the way for the establishment of a human settlement. As researchers continue to explore the possibilities of using bacteria for construction purposes, we may soon see the day when humans are able to build structures on Mars using nothing but the planet’s soil and a little help from microorganisms.
