Maybe they'd be made out of a material known as aerogel.

也许是由一种叫气溶材料构成。

The aerogel in the Stardust was able to collect particles from the comet.

星尘号气凝收集器能收集彗星颗粒。

Aerogels are one of the lightest solid materials in the world.

气凝是世界上最轻固体材料之一。

Aerogels are great for insulation, because the air inside doesn't transfer heat very well.

气凝是缘体，因为其内部气体不太能导热。

Aerogels are gels where all the liquid has been replaced with gas.

气凝是一种内部液体全部被气体替代凝。

We can see lots of impacts into the aerogel. There are big ones and there are small ones.

我们可以看到气凝里有许多撞击痕迹。有大也有小。

Plus, they're almost transparent, which means we could use aerogels to insulate windows here on Earth… when they get cheaper.

再加上它们几乎透明，这也就意味着我们可以在使用气凝，做窗户隔离......还是等它们便宜些吧。

Aerogels are great for insulation, because the air inside doesn’t transfer heat very well.

气凝非常适合隔热，因为里面空气不能很好地传递热量。

Without going into all the details, Kistler won his bet, and at the same time invented  the first aerogel.

在没有详细说明所有细节情况下， 奇石乐赢得了他赌注，同时发明了第一个气凝。

And of course, during this flyby, Stardust had  its aerogel collector exposed, and it was rapidly collecting dust samples.

当然，在这次飞越过程中， 星尘号气凝收集器暴露在外，它正在快收集灰尘样本。

That’s basically how scientists create aerogels: First, they make a gel out of something like silicon or carbon compounds.

这基本上就是科学家们制造气凝方式：首先，他们用硅或碳化合物之类东西制造凝。

Plus, they’re almost transparent, which means we could use aerogels to insulate windows here on Earth… when they get cheaper.

另外，它们几乎是透明，这意味着我们可以使用气凝来隔离地球上窗户… … 当它们变得更便宜时。

The trails left behind in the aerogel would  also be useful for scientists to spot where a particle had been captured.

气凝中留下痕迹也有助于科学家发现粒子被捕获位置。
