VEX-V-VRA-1-2-3-EXT1-0147

Data Set Overview The Venus Express (VEX) Radio Science (VeRa) Data Archive is a timeordered collection of raw and partially processed data collected during the Venus Express Mission. This is a Target Gravity measurement covering the time 20071231T03:11:20.500 to 20071231T04:02:09.500. This data set contains archival raw, partially processed, and ancillary/supporting radio science data acquired during the Routine Operations phase of the Venus Express (VEX) mission using ground facilities of the European Space Agency (ESA) and/or the NASA Deep Space Network (DSN). This is a Target Gravity measurement on Venus. These kind of measurements were typically conducted during Venus Express pericenter over interesting geophysical structures. This particular measurement was conducted over Atalanta Planitia, Coronae. This data set was collected during the VEX science subphase 11 (PH11) 20072008. For more information see MISSION.CAT. Mission Phase Definition The mission phases which are used in the Data Set Identifier DATA_SET_ID correspond to the following table: Phase name | abbreviation | time span Nominal Mission Phase | NMP | 20051109 20071002 Extended Mission 1 | EXT1 | 20071003 20090531 Extended Mission 2 | EXT2 | 20090601 tbd The mission phases are further divided into science subphases. Mission phase and science subphase definitions can be found in CATALOG/MISSION.CAT and DOCUMENT/ESA_DOC/VEX_ARCHIVE_CONVENTIONS.PDF.
