Detailed explanation-1: -IISc, ISRO develops sustainable process for making brick-like structures on Moon.
Detailed explanation-2: -The team first made the slurry by mixing Martian soil with guar gum, a bacterium called Sporosarcina pasteurii, urea and nickel chloride (NiCl 2). “This slurry can be poured into moulds of any desired shape, and over a few days the bacteria convert the urea into crystals of calcium carbonate.
Detailed explanation-3: -Bricks made of a mix of saltwater and dust from the moon or Mars can withstand enough pressure to be used in any future extraterrestrial construction. But astronauts planning on making these will need to figure out how to bake them first.
Detailed explanation-4: -It exploits lunar soil, and uses bacteria and guar beans to consolidate the soil into possible load-bearing structures. These “space bricks” could eventually be used to assemble structures for habitation on the moon’s surface, the researchers suggest.
