MEX-M-MRS-1-2-3-EXT8-4188

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 20210206T08:49:51.000 to 20210206T09:11:59.449. 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）的无线电科学（MaRS）数据档案库，系按时间顺序排列的原始及部分处理数据集合，这些数据是在火星快车号任务期间收集的。有关调查的详细信息，请参阅MaRS用户手册MARSUSERMANUAL2004，该手册位于MaRS文档/MRS_DOC文件夹中。本数据集涉及的时间段为20210206T08:49:51.000至20210206T09:11:59.449的掩星测量。该数据集是在火星快车号扩展任务阶段8（EXT8）2021至2022年期间收集的。在扩展任务期间，共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，其中需区分在火星卫星火卫一上进行的重力测量、在火星轨道远地点进行的全球重力测量以及在火星轨道近地点进行的针对特定地质结构的重力测量。更多信息请参阅INST.CAT或MaRS用户手册MARSUSERMANUAL2004。除非另有说明，所有测量均使用搭载在卫星上的应答机1进行。应答机2作为备用设计。任务阶段定义：值得注意的是，火星快车号（MEX）的无线电科学（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
