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

也许由一种叫气材料构成。

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 gels where all the liquid has been replaced with gas.

气凝一种内部液体全部被气体替代凝。

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

气凝绝佳绝缘体，因为其内部气体不太能导热。

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

气凝世界上最轻固体材料之一。

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迹。有大也有小。

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

首先，科学家从诸如硅或碳化合物中制造明。

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。

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。
