Presentation Transcript

  1. Mars Express • Launch in June 2003, MOI in December 2003 • 9500 orbits completed • The mission is healthy, the operations are smooth • 530 peer-reviewed publications • The archive is regularly populated and being used • Operations until 2014 Olivier Witasse Project Scientist European Space Agency ESA/DLR/FU Berlin (G. Neukum)

  2. Mars Express: A broad range of scientific investigations Study of the Phobos and Deimos moons: Mass, volume and density determination, subsurface structure, surface characterization, interaction with the solar wind, ephemerids, origin. Upper atmosphere: Interaction with the solar wind, escape, exosphere, thermosphere, ionosphere, airglow and aurora Surface: geology compositionclimate Atmospheric science: composition, density, dynamics, thermal, clouds, climate Investigation of gravity anomalies, and time variations of the gravity field Subsurface studies

  3. Pericenter evolution in 2010-2012 Radar sounding of the North Polar Cap Red: latitude Blue: solar elevation angle Today: Lat= 43°N SEA= 20° Pericenter latitude and illumination as a function of orbit number

  4. Scientific impact Top 5 discoveries 5 4 3 2 1

  5. Mars Express Archive Archive regularly populated Availability of higher-level data: HRSC digital terrain model Radio science vertical atmospheric profiles MARSIS Total Electron Content MARSIS topside sounder data (soon) Many more data sets under discussion Data workshops Regularly organised Tutorials, exercises, software online Mars Express OMEGA data workshop, June 2007, ESA/ESAC (Spain)

  6. Mars in 3D, high-resolution and in color ESA/DLR/FU Berlin (G. Neukum)

  7. MEX-MRO collaboration: study of CO2 clouds MEX/OMEGA unambiguously detects clouds with the 4.26 µm feature. This is one of the top 10 MEX discoveries. Complemented by MEX-SPICAM/HRSC/PFS instruments. MRO/CRISM measured clouds in the visible range with an excellent spatial resolution Spatial distribution from multi-instrument data

  8. Phobos flybys

  9. Imaging Phobos …. and Jupiter

  10. Concluding remarks Spacecraft healthy, operations at least until end of 2014 Science at full speed, major discoveries Good archive Fruitful collaborations across missions (MRO, MSL, Phobos Sample Return, …) Support to MSL EDL and surface operations Support to landing site characterization (Mars, Phobos moon)
