站长搜索讯 8月20日消息,最近,上天入地无所不能的NASA又开展了一项新项目,向全世界公开征集解决办法,将宇航员的粪便转化成安全可靠的食物。为此,NASA许诺向中标的项目组每年提供20万美元的研究经费。

据悉,“吃放心粪便”是深空旅行必须攻克的难题之一。如果人类希望登上火星,按照目前航天器的推力计算,宇航员很难带够充足的食物以供往返需求。解决办法基本上有两个,其一是利用冰冻仓进行深空睡眠;其二便是利用所有能够利用的能量,尽可能减少能量浪费,其中就包括“吃屎”。显然,前者过于科幻,而后者的可行性更高。

目前,在国际空间站上,宇航员的液体排泄物可以循环利用,将尿液中的水分提出并转化为饮用水,这项技术已经非常成熟。然而,对于固体排泄物,目前仅能提取其中的水分,而残留的营养物质只能储存在专用的排泄物仓中,并定期处理。

据悉,目前该项目已经启动,位于美国南卡罗莱娜州的Clemson大学已经组成了研究团队,并且已经立项,项目全名:“在封闭回路的太空旅行中关于人类排泄物转化食物、营养物、材料的合成生物学研究。”(Synthetic Biology for Recycling Human Waste into Food, Nutraceuticals, and Materials: Closing the Loop for Long-Term Space Travel)。

据悉,该研究将持续三年,每年的经费为20万美元,NASA希望通过该计划,能让宇航员吃上安全、有营养的“便便”,可大大缓解深空旅行食物不足的问题。
