Space exploration: Dusting yourself down

空间探索:拂去尘埃

A new space suit could resist the damaging effects of sharp lunar dust.


一款新型的宇航服能够抵抗尖利的月尘带来的破坏性影响。


“Picking up some dust.” So said Buzz Aldrin on July 20th 1969, as he and Neil Armstrong descended towards the lunar surface.It is not the most famous quote from that day.But the lunar dust kicked up by Aldrin’s and Armstrong’s descending spacecraft would go on to become a serious, if under-appreciated, problem for all of the Apollo astronauts.


译文


1969年7月20日,Buzz Aldrin与Armstrong降落在月球表面,Aldrin对Armstrong说:“收集一些尘土。”这句话并不是那天他们说的最有名的话。不过,Aldrin和Amrstrong驾驶的宇宙飞船着陆时扬起的月尘如果没有得到恰当的处理,会变成对所有阿波罗计划宇航员来说很严重的问题。


Lunar dust consists of rock pulverised to the consistency of talcum powder by micrometeoroid impacts.The fragments are sharp, and because there is no weather on the Moon, and therefore no erosion, they stay that way.At the same time, the solar wind bombards the dust with charged particles from the sun, giving it a static charge that makes it cling to anything it touches.


译文


月尘是由受流星体撞击影响而变成了滑石粉块的岩石组成的。这些碎片十分锋利,并且因为月球上没有天气之说,没有腐蚀现象,故而它们会一直保持着自己的棱角。与此同时,来自太阳的太阳风让这些尘埃带上了正负电荷,有了电荷它们就能够依附任何它们触碰到的东西。


The jagged dust fragments blackened spacesuits, causing them to absorb too much heat.They tore tiny leaks in joint seals, resulting in pressure leaks and risking total failure of the suits.They scratched visors, hindering visibility, and caked batteries, making them overheat.Tramped back into the spacecraft, they escaped into the air, from where the astronauts had little choice but to breathe them in and risk any potential health consequences.


译文


由于这些锯齿状的尘埃碎片表面温度过高,接触到宇航服时会把宇航服烧焦、使其碳化变黑。尘埃碎片能在宇航服的接缝处撕开一个小口,使宇航服压力失衡而丧失保护作用。尘埃碎片还会划伤宇航服的面具,阻碍其视野,并且由于每粒尘埃都带有电荷,当它们彼此相连就相当于组成了电池组,开始加热。当宇航员回到太空飞船上之后,这些尘埃碎片就会分布在空气中,而宇航员们在不知不觉中被迫将它们吸入,这就对其健康造成了潜在的影响。


注释


1.Pick up 拾起;捡起


例句:Rawlings had been picked up by police at his office.


罗林斯已在办公室遭警察拘捕。


2.return to 返回


例句:I solemnly vowed that someday I would return to live in Europe.


我郑重发誓,总有一天我将回到欧洲生活。


3.At the same time 同时


例句:I was afraid of her, but at the same time I really liked her.


我害怕她,但同时也确实喜欢她。


4.kick up 激起;引起


例句:The child will kick up a row if he doesn't get his own way.


这孩子一不称心就发脾气。
