How can human urine help build buildings on the moon?

The Moon is one of the most probable objects of the Solarsystems where people can soon fully settle down. Although the Earth’s satellite is located at a fairly close distance from us, modern technology allows us to transport only a limited amount of materials for the construction of buildings on the lunar surface, which logically leads us to the need to create everything we need on the Moon itself. One of the most unusual materials, which can become an important element in the construction of the first lunar colony, is considered ordinary human urine. What exactly can it play when a person moves to our natural satellite?

The construction of the first lunar colony is planned to begin in a few years.

Construction on the moon

Man throughout his historyof existence, he looked at the moon, trying to imagine how exactly this pearl-white world looks from close range. The ancestors' dream was fulfilled by the Apollo 11 spacecraft, which in 1969 landed with the crew on the sandy surface of the satellite and showed the first photographs of local landscapes. Be that as it may, the Moon was not the most comfortable place for a person to stay and, after making a couple of photos and videos, the Apollo team returned to Earth.

50 years after the historicmissions, scientists plan to return a person to the moon, developing a number of new programs, which in 1969, humanity could only dream of. So, if earlier missions with human participation were planned for a relatively short time, now people will be able to stay on the earth's satellite for quite long periods of time.

The moon is interesting to scientists not only because you can live on it. The fact is that she can talk about the origin of life on Earth.

In order to be able to successfully implement newlunar programs, humanity will have to learn how to use almost all the resources available to it in construction and daily life. Observance of such a strict rule will be due to the almost complete absence of materials familiar to humans on the Moon, because of which even the urine of the lunar colonists themselves may turn out to be extremely useful.

Surprisingly, the fact is: the use of human urine alone can significantly reduce the prohibitive cost of transporting building materials from the Earth, says

Materials for construction

Urea, which is found in human urine,can be used as a plasticizer for concrete mix - a substance that makes concrete soft and similar to plasticine. An unusual additive will be used in 3D printing of concrete-like materials from moon regolith sand, which will then be used in the construction of full moon buildings. It is believed that such shelters could not only protect future researchers from extreme temperatures and micrometeorite impacts, but even from high levels of radiation and harmful particles of the cosmic wind.

Perhaps soon the first hotels will appear on the moon?

The beneficial properties of urea do not end there.on softening concrete. So, it was found that tubes printed using urea are able to withstand heavy loads and to a large extent retain their stability even after repeated cycles of freezing and thawing. The presence of such a property will come in handy, because temperature fluctuations on the lunar surface can reach 300 ° C!

The temperature difference during the lunar days can reach 300 ° C!

Currently, researchers are onlyThey are developing potential methods for extracting urea from urine, at the same time evaluating the suitability of the substance for the formation of geopolymer concrete necessary for future lunar colonists. If the results of the experiments show positive results, it is worth thinking that urea will indeed prove to be an important component in the fulfillment of the Artemis mission as early as 2024, when the American astronauts - man and woman - will return to the moon with the goal of its gradual colonization.

By the way, earlier we were in already wrote in detail about the problems of NASA's ambitious expedition Artemis, and my colleague, Ramis Ganiev, even talked about how spacesuits designed for a new moon landing in 2024 would look like.
