MEX-M-PFS-2-EDR-EXT3

Data Set Overview The Mars Express (MEX) Planetary Fourier Spectrometer (PFS) Data Archive is a collection of raw data collected during the MEX Mission to Mars. For more information on the investigations proposed see the PFS documentations in the DOCUMENT/ folder. This data set was collected during the MEX Mission phases: First Extension Mission Phase Mission Phase Definition It should be noted that the Mars Express (MEX) Planetary Fourier Spectrometer (PFS) group uses mission phases which deviate from the ones defined in the MISSION.CAT files given by ESA in order to keep the keywords and abbreviations consistent for Mars Express, Venus Express and Rosetta. Those mission phase abbreviations are also used in the data description field of the dataset_id.

数据集概述 火星快车号（Mars Express，简称MEX）行星傅里叶光谱仪（Planetary Fourier Spectrometer，简称PFS）数据档案集收录了火星快车号对火星进行探测任务期间收集的原始数据。关于所提议的调查，请参阅位于DOCUMENT/文件夹中的PFS文档。本数据集的收集过程涵盖了火星快车号任务的不同阶段：

第一阶段扩展任务阶段 任务阶段定义

值得注意的是，火星快车号（MEX）行星傅里叶光谱仪（PFS）小组使用的任务阶段与欧洲航天局（ESA）提供的MISSION.CAT文件中定义的阶段有所不同，以确保火星快车号、金星快车号和罗塞塔号的关键词和缩写的一致性。这些任务阶段的缩写也应用于数据集ID的数据描述字段中。

MaRS任务名称 | 缩写 | 时间跨度

近地验证 | NEV | 20030602 - 20030731

星际巡航 | IC | 20030801 - 20031225

标准任务 | Nominal | 20031226 - 20051130

第一阶段扩展任务 | EXT1 | 20060101 - 20070930

第二阶段扩展任务 | EXT2 | 20071001 - 20091231
