Inspired by freeze-dried fruit, the team is creating a mixture of sand, gelatine and genetically engineered yeast that produces adhesive proteins to strengthen the material.
The researchers are testing the blocks under simulated Martian conditions, although transporting equipment and supplying enough energy remain major obstacles.
