@MarsCuriosity

Betina Pavri, MSL (Mars Science Laboratory) Payload Downlink Coordinator:
Hello, I’m Betina Pavri, payload downlink coordinator, and this is your Curiosity Rover Update.
Betina Pavri, 火星科学实验室有效载荷下行链路协调员：
Hello，我是Betina Pavri，有效载荷下行链路协调员，您现在看到的是好奇号探测车的更新（报告）。

Curiosity continues scooping at Rocknest this week.
好奇号本周继续在Rocknest铲行。

The Mastcam and Navcam instruments provided images and video used to assess the success of the scooping and sample processing activities. These images also provided confirmation that the sampling system was successfully cleaned after the process was completed.
Mastcam和Navcam仪器所提供的图像和视频画面被用来评估掘铲的成功和样本处理的活动。同时这些图像也确认了采样系统在处理完成之后已被成功清空。

Also this week, a soil sample was dropped off to the rovers observation tray for assessment by the science team. This sample was determined to be suitable for drop off to the CheMin instrument.
也是在这周，一件土壤样本被倾倒在探测车观察托盘，用于科学团队的评定。这件样本被判定适合于放置进CheMin仪器。

The CheMin instrument uses X-rays in order to image the sample and determine what minerals make it up. This helps geologists understand how the rock formed and how it’s related to other rocks we’ve studied so far on Mars.
这台CheMin仪器使用X射线成像样本，并确定它是由哪些矿物质组成。这可以帮助地质学家了解这块岩石是如何形成，以及它是如何与迄今为止在火星上已经研究了的其它岩石相关联。

Scientists identified numerous bright grains in the soil. Because of this small piece of plastic from the landing event that had been found earlier in the week, the team proceeded cautiously, dumping the second scoop collected and imaging the bright grains.
科学家辨认出了土壤中数目众多的明亮颗粒。因为在本周早些时候发现了着陆事件造成的小片塑料，团队成员小心翼翼倾卸第二铲收集物，并对明亮的颗粒物成像。

These bright grains were later determined to be components of the Martian soil, and therefore, the sample was deemed to be suitable for delivery to the CheMin instrument for analysis.
这些明亮的颗粒物，最后被确认是火星土壤的组分，因此，样本被认为适合于交付到CheMin仪器进行分析。

The science team requested Mastcam and Navcam mosaics of outcrops in the direction of Glenelg, to plan Curiosity's journey to this next science destination.
在去往Glenelg的路上，科学家们在好奇号Mastcam（全景摄像机）和Navcam（导航摄像机）上获取了裸露岩石的拼接全景图像（此句翻译不太确定，请教讨论），以规划好奇号下一个科学目标目的地的旅程。

This has been your Curiosity Rover Update. Please check back for future reports.
以上就是好奇号探测车的更新（报告）。请持续关注我们未来的更新。

Mastcam这玩意好像是数控加工编程软件。。。
NavCam应该是导航相机的型号什么的吧。。。...

谢谢路版提供信息，进一步查了资料。

一般生活中原本像你所查到的MasterCAM（注意和原文提到的MastCAM不同）是CNC Software, Inc. 的数控加工（computer numerical controlled (CNC)）软件，
而NavCam是MosaicMill Ltd的飞行器导航和相机控制软件。

但是实际上在Mars Science Laboratory的Curiosity Rover计划里，
1. "The Mast Camera, or Mastcam for short, will take color images and color video footage of the Martian terrain.
The images can be stitched together to create panoramas of the landscape around the rover. "




2. Two Pairs of Engineering Navigation Cameras (Navcams):

Mounted on the mast ( the rover "neck and head" ), these black-and-white cameras use visible light to gather panoramic, three-dimensional (3D) imagery.
The navigation camera unit is a stereo pair of cameras, each with a 45-degree field of view that will support ground navigation planning by scientists and engineers.
They work in cooperation with the hazard avoidance cameras by providing a complementary view of the terrain.




3. Science instruments are state-of-the-art tools for acquiring information about
the geology, atmosphere, environmental conditions, and potential biosignatures on Mars.
