纪录片《火星任务》 第34期 检测石头（在线收听）

And then look at the emissions that come off from that rock,

然后检测石头发出的光

and that's really important

这是非常重要的

because it can tell the differences

因为这可以区分

between different types of rocks.

不同种类的岩石

So if we come across a rock that looks substantially different

当我们发现一块岩石

from rocks we've looked at before,

和以往发现的岩石明显不同

then we might want to approach those samples,

我们就会靠近这些样本

put out the arm,

伸出机械臂

and start interrogating that rock or that outcrop

用机械臂上的仪器

with instruments that are on the arm.

对岩石或表面岩层进行分析

An element analyser and a very nice microscope,

我们先用元素分析仪和强大的显微镜

and if we examine the outcrop or the rock with those tools

检测岩石或表面岩层

and decide it's worth even further exploration,

如果认为它值得进一步研究

then what we do is we sample the rock.

我们就会对岩石取样

We drill into the rock,

在岩石上钻孔

we create some powder with the sampling system

通过取样系统制成粉末

and then we deliver that powder into SAM.

之后送回到火星样本分析仪里

The chemical analysis of this powdered rock

对岩石粉末进行化学分析

is one of the most important tests in the mission.

是这次任务中最重要的检测项目之一

That's why the team are still running tests

所以该小组仍在地球上测试

on SAM's twin back here on earth.
