MEX-X-MRS-1-2-3-EXT7-4064

Data Set Overview The Mars Express (MEX) Radio Science (MaRS) Data Archive is a timeordered collection of raw and partially processed data collected during the MEX Mission to Mars. For more information on the investigations see the MaRS User Manual MARSUSERMANUAL2004 in the MaRS DOCUMENT/MRS_DOC folder. This is a Solar Conjunction measurement covering the time 20190918T21:05:00.000 to 20190919T02:20:00.000. This data set was collected during the MEX Extended Mission Phase 7 (EXT7) 2019 to 2020. There were four types of scientific measurements conducted during Extended Mission: Solar Conjunction, Occultation, Bistatic Radar and Gravity where one has to distinguish between gravity measurements conducted on Phobos as well as global gravity measurements on Mars which were conducted around apocenter and target gravity measurements on Mars which were conducted around pericenter over interesting geophysical structures. For more information see INST.CAT or the MaRS User Manual MARSUSERMANUAL2004. For all measurements if not indicated otherwise Transponder 1 onboard the s/c was used. Transponder 2 is designed to be a backup. Mission Phase Definition It should be noted that the Mars Express (MEX) Radio Science (MaRS) 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, and Rosetta. For Venus Express other definitions are used. 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（Mars Express，简称MEX）无线电科学（MaRS）数据存档是由火星快车任务期间收集的原始及部分处理数据按时间顺序组成的集合。有关调查的更多信息，请参阅MaRS用户手册MARSUSERMANUAL2004，该手册位于MaRS文档夹/MRS_DOC中。本数据集为涵盖20190918T21:05:00.000至20190919T02:20:00.000时间的太阳会合测量。该数据集收集于2019至2020年火星快车扩展任务第7阶段（EXT7）期间。在扩展任务期间，进行了四种类型的科学测量：太阳会合、掩星、双站雷达和重力测量。其中，需区分在火卫一上进行的重力测量以及在全球范围内进行的火星重力测量，这些测量是在火星的远日点附近进行的，以及围绕近日点在有趣的地球物理结构上进行的重力测量。更多信息请参阅INST.CAT或MaRS用户手册MARSUSERMANUAL2004。对于所有测量，除非另有说明，否则使用搭载在航天器上的应答器1。应答器2设计为备用。任务阶段定义：值得注意的是，火星快车（MEX）无线电科学（MaRS）小组使用的任务阶段与ESA提供的MISSION.CAT文件中定义的任务阶段有所不同，以保持火星快车和罗塞塔的关键词和缩写的一致性。对于金星快车，则使用其他定义。这些任务阶段的缩写也用于dataset_id的数据描述字段中。MaRS任务名称 | 缩写 | 时间范围
