MEX-X-MRS-1-2-3-EXT5-3783

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 20150629T00:06:15.000 to 20150629T08:02:40.500. This data set was collected during the MEX Extended Mission Phase 5 (EXT5) 2015 to 2016. 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.

数据集概览：火星快车号（Mars Express，简称MEX）无线电科学（MaRS）数据存档为按时间顺序排列的原始及部分处理数据集，这些数据是在火星快车号任务期间收集的。关于调查的更多信息，请参阅MaRS用户手册MARSUSERMANUAL2004，位于MaRS文档/MRS_DOC文件夹中。本数据集是一项针对20150629T00:06:15.000至20150629T08:02:40.500时间段的太阳联合测量。该数据集是在2015至2016年的MEX扩展任务第五阶段（EXT5）期间收集的。在扩展任务期间进行了四种类型的科学测量：太阳联合、掩星、双站雷达和重力测量。在重力测量方面，需区分在火卫一上进行的重力测量以及火星全球重力测量，后者是在火星远日点附近进行的，而针对火星有趣地球物理结构的近日点重力测量则是在火星近日点附近进行的。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，否则均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，火星快车号（MEX）无线电科学（MaRS）小组使用的任务阶段与ESA提供的MISSION.CAT文件中定义的阶段不同，以便保持火星快车号、罗塞塔号的关键词和缩写的一致性。对于金星快车号，则使用其他定义。这些任务阶段缩写也用于dataset_id的数据描述字段中。MaRS任务名称 | 缩写 | 时间范围
