Astronaut urine could be key to colonizing the Moon

Urine could become a by-product of creating new material to live on in planets and natural satellites.

For centuries, humanity has dreamed of living on the lunar surface. We already know how to get there, now we have to solve the problem of where we are going to live. carry around A pound of the material in space costs about $10,000., so building a complete module on our satellite would be prohibitively expensive. For this reason, agencies explore alternative materials that can be obtained on the Moon.

From extreme temperature fluctuations to radiation and the occasional meteorite impact. Future astronauts living on the surface of the Moon will have to endure conditions far more extreme than on Earth. This means that the buildings they live in have to be able to withstand the trappings of this unique environment.

Although it may not be very pleasant to imagine, Urine is a great resource for manufacturing in space because of urea, which is the second most abundant component of urine after water., and it benefits It’s free, practically unlimited and doesn’t require carrying Since the same astronauts build it autonomously.

Urea can break hydrogen bonds and reduce the viscosity of liquid mixtures. found in experiments that when they mixed with urea Chandra Polymers (extracted from the ground), the concrete that was manufactured was up to 10 times more resistant and much more malleable than terrestrial,

Properties are maintained in materials even after being solidified multiple times to simulate natural satellite climate change for this reason it was determined that urea was an essential alloying component for their preparation.

This is very practical and avoids the need to further complicate sophisticated water recycling systems in space.

“The hope is that astronaut urine could be used essentially as it is on a future lunar base with minor adjustments to the amount of water. This is very practical and will allow more complex sophisticated water recycling systems in space.” avoids the need for,” he explains. marlies arnhof, Study co-author.

bricks in space

In India, research in this area follows a similar path. Whereas, researchers Invented a new technique of making bricks that also uses urea, which can be obtained from urine or bacteria are called Pasteuria spore loadbut uses Goma Guar Instead of cement as support.

This substitution is interesting because Guar gum is obtained from a podThis way Reduces carbon footprint of manufacturing, even, This more ecological and resistant material can be used in land construction.

“We have a long way to go before we see extraterrestrial habitats. Our next step is to make larger bricks with a more automated and parallel production process,” says Kumar, one of the study’s researchers. Want to further improve the strength and test them under different loading conditions such as impact and possibly a moonquake,” he explained.
