呃，當然，太空石掉到地球上也不一定是好事。

But fortunately, you know, this was very controlled.

但幸運的是，你知道，這是很好的控制。

In fact, it was an amazing technological achievement.

事實上，這是一項驚人的技術成就。

And this sample coming back in a little metal capsule of sort of human made flying saucer, if you will, coming back from this 4.6 billion years old Asteroid re Hugo, which is just about 900 m in diameter but absolutely pristine rock.

這個樣本是在一個小金屬艙裡傳回來的 人類製造的飛碟，如果你願意的話 從46億年前的小行星雨果上傳回來的 這顆小行星直徑只有900米，但絕對是原始岩石

But, you know, just being exposed to the air and the radiation on Earth from the sun means that the sample may change.

但是，你知道，僅僅是暴露在空氣中 和地球上來自太陽的輻射意味著樣本可能會改變。

So you just have to make sure that it remains really airtight and capture those gasses that were trapped inside the rock samples because they're the really exciting key toe.

所以，你只需要確保它保持真正的密封性，並捕捉那些被困在岩石樣本中的氣體，因為它們是真正令人興奮的關鍵腳趾。

 What things were like 4.6 billion years or so ago.
