时差N小时 月球尘埃的危害有多大?(下)（在线收听）

And moon dust is clingy; it gets all over spacesuits and inside space capsules.

而且月球尘埃很有依附性，太空服太空舱里面都会有。

Astronauts from the '60s and '70s used to complain that there was so much dust inside the capsule that they could smell it.

二十世纪六七十年代的宇航员们曾经抱怨，太空舱里面有太多的灰尘，甚至他们都能闻得到。

So is the dust actually dangerous? What happens if it gets in the lungs?

那么灰尘对身体有害吗?如果它进入肺里会怎样?

That's what scientists are studying now.

那就是科学家们现在正在研究的。

One issue is that the moon's weak gravity could allow dust particles to float around in an astronaut's airway, which could let moon dust penetrate deeper into the lungs.

一个问题就是,月球的低重力会让尘埃粒子飘进宇航员的导气管,这可能让月球尘埃更深地穿透进人的肺部。

Which increases the health risks.

这就增加了健康风险。

So what can astronauts do to breath in less dust? High-tech feather dusters?

那么怎么做才可以让宇航员吸入较少的粉尘?高科技的鸡毛掸子吗?

Funny. But it's a good question–one that scientists are busy looking into before sending astronauts up there to set up house on our very dusty moon.

太逗了。不过这确实是个好问题。这是科学家们正在忙于调查的问题，要在将宇航员们送上太空造房生活之前解决的问题。
