Abstract This is a Commissioning measurement covering the time 2003-07-10T12:45:00 to 2003-07-10T19:30:00.
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 Commissioning measurement covering the time 2003-07-10T12:45:00 to 2003-07-10T19:30:00. This data set was collected during the MEX Mission Near Earth Verification Phase (NEV) - shortly after launch. No specific measurement was done on this day but the configuration was tested. Testing was done during the NEV, CR1 and partly MCO Mission phase. During NEV several comissioning measurements were performed which had to purpose to test the radio transponders and oscillator aboard the space craft as well as the equipment at the ground stations mainly at the new ESA ground station New Norcia (NNO). For more information see INST.CAT or the MaRS User Manual [MARSUSERMANUAL2004]. Overview of perfomed measurements: DOY 180, 2003-06-29: Tracking at New Norcia performed in the so called TWOD-X configuration. That is, X-Band uplink at IFMS 1 and X and S-Band coherent and simultanous downlink. Doppler recording was performed all the time. -18:00 UTC: TM ON, Ranging ON -19:45 UTC: TM OFF, Ranging OFF -23:45 UTC: TM ON, Ranging ON -01:00 UTC: End of operation Data sample rate was 1/sec. DOY 182, 2003-07-01: Tracking at New Norcia performed in the so called TWOD-X configuration. That is, X-Band uplink at IFMS 2 and X and S-Band coherent and simultanous downlink. Doppler recording was performed all the time. -18:00 UTC: TM ON, Ranging ON -19:05 UTC: TM OFF, Ranging OFF -23:05 UTC: TM ON, Ranging ON -00:05 UTC: End of operation Data sample rate was 1/sec. DOY 183, 2003-07-02: Tracking at New Norcia performed in the so called TWOD-S configuration. That is, S-Band uplink at IFMS 1 and X and S-Band cohe...

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 (Khazakstan) 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 cont...
