Moon dirt is full of glass particles from micrometeorite impacts.

月球土壤充满了微陨撞击产生的玻璃颗粒。

Oh yeah, that's just, you know, a micrometeorite, you know, probably entering the atmosphere, a piece of debris entering the atmosphere.

哦是的，那只是，你知道的，一个微生物陨，你知道的，可能进入大气层。一块碎片进入大气层。

Each new micrometeorite is its own mystery.

- 每个新的微陨都有其自身的奥秘。

We're obviously not going to find anything big, but tiny micrometeorites, they're actually everywhere.

显然不会找到任何大的，但微小的微陨， 际上无处不在。

This is in almost every kind of meteorite and micrometeorite I can think of.

这几乎存在于能想到的每一种陨和微陨。

So this is almost pretty much nails this as being a micrometeorite.

所以这几乎是一颗微陨。

We enlisted the help of the amateur scientist who proved that micrometeorites could be found.

得到了一位业余科学家的帮助，他证明可以找到微陨。

There wasn't a lot of data out there about what micrometeorites actually looked like.

关于微陨际是什么样子的数据并不多。

Which means 3500 micrometeorites hit it year, after year, after year.

这意味着 3500 颗微陨年复一年地撞击。

Jon estimates that about 80% of micrometeorites are metallic, so we'll focus on those.

乔恩估计大约 80% 的微陨是金属的，因此将重点关注这些。

High walls can also help prevent micrometeorites from being carried away by the wind.

高墙也有助于防止微陨被风带走。

So a key technology we need as a space station company is the ability to handle micrometeorite strike that might happen.

因此，作为一家空间站公司，需要掌握的关键技术之一是应对可能发生的微流星体撞击的能力。

So, within the first year, I had found 500 different micrometeorites.

因此， 在第一年内，发现了 500 种不同的微陨。

A micrometeorite is so small that you can only keep a tiny cross section in focus at a time.

微陨非常小，一次只能聚焦一个很小的横截面。

Others think the micrometeorites come from much further out in the solar system.

- 其他人认为微陨来自太阳系更远的地方。

The paper said micrometeorite impact and solar wind irradiation, the dominant space weathering processes, largely modified the composition and microtexture of soil materials on the moon.

微陨撞击和太阳风照射是月球上主要的空间风化过程，在很大程度上改变了月球上土壤物质的组成和微结构。

Jon's next steps are trying to figure out where in the universe all of these micrometeorites came from.

乔恩的下一步是试图找出宇宙所有这些微陨的来源。

So there's this process called gardening, which is just the micrometeorite, constant rain of micrometeorites.

所以有这个过程称为园艺，就是微陨，不断的微陨雨。

But with no Earth-like atmosphere or magnetic field to repel solar radiation and micrometeorites, space colonists would probably need to pile metres-thick rocks and geological rubble onto the roofs of such off-world settlements.

但是， 由于没有类似地球的大气层或磁场来排斥太阳辐射和微陨，太空殖民者可能需要在这些地外定居点的屋顶上堆放数米厚的岩和地质碎。

We're just working on a paper where we just calculated, this was super fun, we calculated how long would the Lunar Lander exist on the moon before micrometeorites just chewed it down, right?

正在撰写一篇论文，在论文计算了登月舱在月球上能存在多久才会被微流星体完全侵蚀掉，这真的很有趣。
