While flying over a region of Mars called Cydonia, the orbiter snapped an image of a land formation under cross lighting.

在飞越火星名叫基多尼亚的区域时，卫星拍摄到了一幅在交叉照亮下的地表造型。

In other words, if you want to know how a land formation was formed, the first thing you probably want to know is how old it is. It’s fundamental.

换句话说，如果你想知道地层是如何形成的，你可能首先想知道的是它有多少年。这是基本的。
