Abstract This dataset contains the Level 5 data that have been processed to produce Total Electron Count data from the MARSIS subsurface sounder on Mars Express. Details of the calibration and processing reports are found in the documntation associated with this data set.
Description Data Set Overview = MARSIS Level 5 data products consist of the Total Electron Content data, derived from the MARSIS data. Processing The processing is explained in detailed in the three reports: IONOPROCESS_REPORT1.PDF, IONOPROCESS_REPORT2.PDF, and IONOPROCESS_REPORT2.PDF, included in the /DOCUMENT directory. Useful information can also be found in the peer-reviewed article: Correction of the ionospheric distortion on the MARSIS surface sounding echoes, by Mouginot et al., Planetary and Space Science, Volume 56, Issue 7, p. 917-926, 2008. Data Some data have been published in: Estimation of the total electron content of the Martian ionosphere using radar sounder surface echoes, by A. Safaeinili et al., Geophysical Research Letters, Volume 34, Issue 23, CiteID L23204, 2007. Review These data have been reviewed by the instrument team and are of the highest quality that can be generated at this time. Science results based on these data have been published in journals. The dataset has also been reviewed by an independeent expert. Limitations = There are no known limitations at this time.

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...
