新奇事件簿 宇航员尿液可帮助建立月球基地（在线收听）

New materials could be used to make buildings on the Moon. Scientists from Holland, Italy, Norway and Spain say a new kind of concrete could be made with moon dust and the urine passed by astronauts. The scientists said there is a chemical compound in human urine called urea. This could help things stick together to make a kind of concrete. Scientists would use 3D printers to create the construction material. Three of the world's main space agencies could start using this technique to make buildings for a permanent moon base. NASA, the European Space Agency (ESA) and the China National Space Administration are all interested in colonizing the Moon with research stations.

新材料可以用来在月球上建造建筑物。来自荷兰、意大利、挪威和西班牙的科学家表示，用月球尘土和宇航员的尿液可以制成一种新型混凝土。科学家们表示人类尿液中有一种被称为尿素的化合物。这种物质可以帮助物质粘在一起，形成一种混凝土。科学家们将使用3D打印机来制造建筑材料。世界上三大主要太空机构可以开始使用这种技术建造永久性月球基地。欧洲太空总署NASA以及中国国家航天局都有兴趣在月球上建立研究站。

Using astronaut pee and moon dust could save scientists a lot of money. It costs about $10,000 to transport 0.45kg of materials from Earth to the Moon. The urine and moon dust alternative would be a much cheaper way of constructing things. A scientist said: "We have seen that a waste product, such as the urine of the personnel who occupy the moon bases, could be used." She added: "The actual water in the urine could be used for the mixture, together with water that can be obtained on the Moon, or a combination of both." Scientists say another source of water on the Moon is in the ice that exists in some areas. The scientists say they need to do more tests to find the best building material.

使用宇航员的尿液和月球尘土可以为科学家节省一大笔钱。把0.45公斤的材料从地球运到月球大约需要1万美元。使用尿液和月球尘埃来替代将是一种更便宜的建造方式。一名科学家表示：“我们已经看到，月球基地人员的尿液等废物可以被利用。”她补充道：“尿液中的实际水分，以及在月球中获得的水，或者两者的结合，都可被用于混合物中。”科学家表示月球中另一种水资源是存在于某些区域中的冰。科学家表示他们需要做更多的测试来发现最好的建筑材料。
