Để đạt được tham vọng lên Mặt Trăng định cư

các phi hành gia có thể xây trạm trên mặt trăng bằng... nước tiểu :D

The modules that the major space agencies plan to erect on the Moon could incorporate an element contributed by the human colonizers themselves: the urea in their pee. European researchers have found that it could be used as a plasticizer (chất làm mềm dẻo) in the concrete (bê tông) of the structures.
NASA, the European Space Agency (ESA) and its Chinese counterpart plan to build moon bases (trạm nghiên cứu trên mặt trăng) in the coming decades, as part of a broader space exploration plan (kế hoạch thăm dò không gian) that will take humans to more distant destinations (các diểm đến xa hơn), such as Mars (sao hỏa).
However, the colonization (định cư) of the Moon poses problems such as high levels of radiation, extreme temperatures, meteorite bombardment (sao băng) and a logistical issue: how to get construction materials there, although it may not be necessary.
Transporting about 0.45 kg from the Earth to space costs about $10,000, which means that building a complete module on our satellite in this way would be very expensive. This is the reason why space agencies are thinking of using raw materials from the moon’s surface, or even those that astronauts (phi hành gia) themselves can provide, such as their urine (nước đái)...
