MEX-M-MRS-1-2-3-EXT8-4271

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 Occultation measurement covering the time 20220527T08:25:18.000 to 20220527T11:00:04.000. This data set was collected during the MEX Extended Mission Phase 8 (EXT8) 2021 to 2022. 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）数据存档系按时间顺序排列的原始数据及部分处理数据的集合，这些数据是在火星快车号火星探测任务期间收集的。关于调查的更多信息，请参阅MaRS用户手册《MARSUSERMANUAL2004》，位于MaRS文档夹下的/MRS_DOC目录。本数据集涵盖了从20220527T08:25:18.000至20220527T11:00:04.000的掩星测量。该数据集是在MEX扩展任务阶段8（EXT8）2021至2022年期间收集的。在扩展任务期间进行了四种类型的科学测量：太阳 conjunction、掩星、双站雷达和重力测量。重力测量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，这些测量是在火星远日点附近进行的，以及围绕近地轨道附近的火星有趣地质结构进行的重力测量。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，否则使用搭载于航天器上的应答器1。应答器2设计为备用。任务阶段定义：需要注意的是，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》文件中定义的任务阶段有所不同，以保持火星快车号、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。这些任务阶段的缩写也用于dataset_id的数据描述字段。MaRS任务名称 | 缩写 | 时间范围
