The moon is one of the most likely objects in the Solar system, where in a short time can fully settle people.the earth’s satellite is located at a fairly close distance from us, modern technology allows us to transport to the lunar surface only a limited number of materials for the construction of buildings, which logically leads us to the necessity of creating all the necessary in the moon. One of the most unusual materials, which can be an important element in the construction of first lunar colony is considered normal human urine. What exactly is the role it can play in moving human on our natural satellite?
Construction on the moon
People throughout the history of its existence, looked at the moon, trying to imagine how exactly this looks like pearl white the world at close range. Ancestors dream was able to fulfill spacecraft “Apollo-11 in 1969 landed with the crew on the sandy surface of the satellite and showed the first pictures of the local scenery. Whatever it was, Luna was not the most comfortable place to stay and taking a few photos and videos, the team Apollo returned to Earth.
After 50 years since the historic mission, scientists plan to return humans to the moon, developing a number of new programs, which in 1969, mankind could only dream of. So, if earlier mission involving human subjects planned at a relatively short time, now people will be able to remain on the earth’s moon for quite long periods of time.
In order to be able to successfully implement the new lunar program, humanity will have to learn to use in construction and daily life almost completely all available resources. Compliance with such strict rules will be due by the almost complete absence on the moon are familiar to man because of what an extremely useful substance may be even piss themselves the lunar colonists.
Materials for construction
Urea, which is contained in human urine can be used as the plasticizer concrete mixtures — substances, making the concrete soft and similar to clay. Extraordinary Supplement to be used while 3D printing botanophobia materials from the lunar sand-regolith, which will then be used in the construction of a full lunar buildings. It is believed that this shelter would not only protect future explorers from extreme temperatures and impacts of micro-meteorites, but even from high levels of radiation and particles of solar wind.
Useful properties of urea do not end only on the softening of concrete. So, it was discovered that the tube printed with the use of urea, able to withstand heavy load and substantially retain their stability even after repeated cycles of freezing and thawing. The presence of such properties will be very useful, because fluctuations in temperature on the lunar surface can reach 300°C!
Currently, researchers are developing potential methods of extraction of urea from urine, at the same time evaluating the suitability of a substance for the formation of necessary for future lunar colonists geopolymer concrete. If the results of the experiments show positive results, think that urea really are an important component in the performance of the mission “Artemis” in 2024, when the American astronauts — the man and the woman return to the moon with a view to its gradual colonization.
