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

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。

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。有有小。

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上窗户… … 当它们变得更便宜时。
