NASA重金征集'太空排泄'方案

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？现实中，宇航员们就因为穿着笨拙的宇航服而无法接触自己的身体，加上完全失重状态下排泄物很难清理，因此，在太空上厕所成了一大难问题。近日，美国航空航天局（NASA）拿出3万美元，用以奖励能切实解决“太空排泄”难题的人。 When you've got to go, but you're out there in space, zipped up in a spacesuit, with no toilet in sight and a crew of other astronauts around, what do you do? The two men and one woman who packed themselves into a Russian Soyuz space capsule last week had to wait two full days between launching from Kazakhstan and arriving at the International Space Station. “联盟号”配备了便携式厕所，它看起来像是一个空气动力小便壶。 On future missions to deep space destinations like an asteroid or Mars, NASA suspects it could take up to 144 hours, or six days, to get to a proper toilet. 问题是，在失重状态下液体变成水珠浮于表面，而固体会漂浮在空中。 "You don't want any of these solids and fluids stuck to your body for six days," NASA said, recalling how easy babies can get diaper rash. 美国宇航局表示，“你不会想要任何这类固体和液体在身上停留6天时间。”这让人联想到婴儿很容易得尿布疹。 Currently, while at the International Space Station, astronauts use a toilet contraption that includes a vacuum and a tube to help evacuate fecal matter.
