Will humans reach Mars by the 2030s? 🧐
, the researchers outline their plan for combining Martian soil with a gel-like material called guar gum, urea, nickel chloride, and a bacteria strain called Sporosarcina pasteurii. All of that would form the building blocks for habitats on the red planet.
The proposal joins a list of odd building material proposals for Mars that reflect the scarcity of materials for future missions to the red planet, and the requirement to make the most of any and every resource available.
The specific type of bacteria also helped to overcome the issue of porosity, one of the main obstacles to building habitats on Mars. "The bacteria seep deep into the pore spaces, using their own proteins to bind the particles together, decreasing porosity and leading to stronger bricks," explained Aloke Kumar, one of the senior authors of the paper.
Combined, this material can be used as a binding agent to hold Martian soil together and build habitats for future missions to the red planet. Currently, NASA estimates it will send humans to Mars by the 2030s, and SpaceX is hard at work on its fully reusable, which it aims to send to the Moon and eventually to Mars. Next, the ISRO team aims to send some of their"bacteria bricks" into space on a future ISRO mission.
