So this is what a typical ice core sample looks like.

这就是典型的冰芯样本的样子。

The core sample was given to a man named Robert Phillips.

岩芯样本被交给了一个名叫罗伯特·菲利普斯（Robert Phillips）的人。

NASA engineers later reported that the rock the rover drilled into must not have been strong enough to produce a core sample.

美国国家航空航天局的工程师后来报告说，火星车钻入的岩石一定不够坚固，不足以产生岩心样本。

Wouldn't that have shown in core samples? " " What would have shown?

这不会在核心样本中显示出来吗？”“会显示什么？

We got the preliminary report back of the core samples.

我们拿到了核心样本的初步检测报告。

And interesting enough in one of these probe, in one of these core samples, they found a tiny piece of a meteorite, a fossil meteorite.

在这些探测中非常有趣的是，在一个岩芯样本里他们找到了一小块陨石，化石陨石。

" It's official: I've now captured, sealed, and stored the first core sample ever drilled on another planet, in a quest to return samples to Earth" .

" 这是官方消息：我现在已经捕获、密封并储存了第一个在另一颗行星上钻取的岩心样本，目标是将样本带回地球。"

Secondly, it did something it never had been  designed to do – it emptied out its core sample tube onto the floor.

其次，它做了一些从未设计过的事情——将核心样品管倒在地板上。

Right. So what we see from the core samples is ultimately the climate makes sense. If the sun gets brighter, it gets warmer.

正确的。所以我们从核心样本中看到的最终是气候是有道理的。如果太阳变得更亮，它就会变得更暖和。

Other methods have been used to study the ancient climate, like analyzing marine core samples, and the ratios of carbon isotopes in fossil leaves.

其他方法已被用于研究古代气候，例如分析海洋核心样本以及化石叶子中碳同位素的比率。

The latest core sample -- and all others collected from now on – will be stored on Mars until they can be picked up during future missions to the Red Planet and brought to Earth.

最新的岩心样本——以及从现在开始收集的所有其他样本——将被储存在火星上，直到它们可以在未来前往这颗红色星球的任务中被取走并带回地球。

So when you look at those core samples, you see this fluctuation up and down. What's to say that -- a lot of that happened way before humans were around.

所以当你查看那些核心样本时，你会看到这种上下波动。也就是说——很多事情发生在人类出现之前。

And he tells Valerie and Marta one  day he's out there, you know, just doing his normal research, which is, like, taking these  pencil-shaped core samples from these trees, and he notices something he hadn't seen before.

拉蒂夫：有一天他告诉瓦莱丽和玛塔，他在那里，你知道，只是做他的正常研究，就像从这些树上采集这些铅笔形状的核心样本一样，他注意到了一些他以前从未见过的东西。
