Abstract This is a Occultation measurement covering the time 2005-12-09T02:13:00 to 2005-12-09T02:32:00.
Description Data Set Overview The Mars Express (MEX) Radio Science (MaRS) Data Archive is a time-ordered collection of raw and partially processed data collected during the MEX Mission to Mars. For more information on the investigations proposed see the MaRS User Manual [MARSUSERMANUAL2004] in the MaRS DOCUMENT/MRS_DOC folder. This is a Occultation measurement covering the time 2005-12-09T02:13:00 to 2005-12-09T02:32:00. This data set was collected during the MEX Mission Prime Mission Phase (PRM) 2004-2005. There were three types of scientific measurements conducted during PRM: Occultation, Bistatic Radar and Gravity where one has to distinguish between global gravity measurements which were conducted around apocenter and target gravity measurements 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.

Mission Description Mission Overview Mars Express was the first flexible mission of the revised long-term ESA Science Programme Horizons 2000 and was launched to the planet Mars from Baikonur (Kazakhstan) on June 2nd 2003. A Soyuz-Fregat launcher injected the Mars Express total mass of about 1200 kg into Mars transfer orbit. Details about the mission launch sequence and profile can be obtained from the Mission Plan (MEX-MMT-RP-0221) and from the Consolidated Report on Mission Analysis (CREMA)(MEX-ESC-RP- 5500). The mission consisted of (i) a 3-axis stabilized orbiter with a fixed high-gain antenna and body-mounted instruments, and (ii) a lander named BEAGLE-2, and was dedicated to the orbital and in-situ study of the interior, subsurface, surface and atmosphere of the planet. After ejection of a small lander on 18 December 2003 and Mars orbit insertion (MOI) on 25 December 2003, the orbiter experiments began the acquisition of scientific data from Mars and its environment in a polar elliptical orbit. The nominal mission lifetime for the orbiter was 687 days following Mars orbit insertion, starting after a 5 months cruise. The nominal science phase was extended (tbc) for another Martian year in order to complement earlier observations and allow data relay communications for various potential Mars landers up to 2008, provided that the spacecraft resources permit it. The Mars Express spacecraft represented the core of the mission, being scientifically justified on its own by investigations such as high- resolution imaging and mineralogical mapping of the surface, radar sounding of the subsurface structure down to the permafrost, precise determination of the atmospheric circulation and composition, and study of the interaction of the atmosphere with the interplanetary medium. The broad scientific objectives of the orbiter payload are briefly listed thereafter and are given more extensively in the experiment publications con...
