宇航员“太空排便”难 NASA出3万美元求解决方案

原标题:宇航员“太空排便”难NASA出3万美元求解决方案

参考消息网11月25日报道法媒称,如果奔赴火星途中你裹在宇航服中,可是你又迫切需要“解决问题”,怎么办呢?美国航空航天局(NASA)拿出30000美元,用以奖励能切实解决“太空排便”难题的人。

据法新社11月23日报道,参与者可在12月20日前提交参加竞赛的解决办法,NASA需要在执行太空任务时没马桶的情况下不用双手、长至6天的解决方案。

NASA在其对竞赛的描述中说:“老办法仍是尿裤,但是这只是一个临时的解决办法,没办法在健康和保护身体的状况下持续超过一天。”

报道称,然而,宇航员通常要熬超过24小时后才能再上厕所。一周前升空的联盟号载人飞船上的三名宇航员,要飞行两天的时间方能抵达国际空间站。俄罗斯密封舱是唯一装备了一个便携式马桶的地方。

本世纪30年代可能会有飞往火星的更远的太空旅途,NASA认为宇航员可能要在没有厕所的情况下坚持6天。NASA解释说,一旦进入宇航服,“宇航员就不可能接触自己的身体,连挠鼻子都不行”。为此,NASA拿出30000美元奖金寻求带有排便系统的宇航服方案。

NASA称,要避免粪便和皮肤长期接触导致感染或发炎。同时,也要考虑到在几乎零重力情况下避免液体飘散到空中。

NASA希望一年内能对最好的方案进行试验,争取在三年内投入使用。(编译/芦龙军)
