27/04/2004 2004 EUG MAGE Meeting

Summer School in Les Houches Physics Centre of Les Houches (France) 28 April – 9 May 2003

“Planet Mars”. 5 lectures given by MAGE scientists (C. Jaupart, M. Wieczoreck,

G. Manhes, IPGP, F. Costard, Orsay-Terre, T.Spohn, IfP). Generally, the 2003-2004 was NOT used: USE your budget now Very little papers published have properly acknowledged the

MAGE network: THINK TO DO IT Very little papers done in collaborations List of TASKS for the research activities need to be used First year report done and send by email to lab coordinators

Task 1: A p riori model of the Tharsis Area: This task will consist in the determination of thelithospheric structure by using all type of data from the MGS NASA. Further constraints will beobtained by the Gamma Ray experiment onboard the 2001 Mars Odyssey orbiter. Such approach willconsist in wide multi-disciplinary approach for constraining this geologic province of Mars, which isvery likely constraining strongly the thermal evolution of the planet.

Task 2: Geologic characterization of the landing sites : This task will consist in the geomorphologicinvestigation of the landing site. This will be based on interpretation of orbital remote sensing datafrom other missions. In particular, imaging data (Viking Orbiter, MOC onboard MGS, Themis onboard2001 Mars Odyssey) and topographic data (MOLA onboard MGS) and latter Mars Express will beused for this task, as they provide the geologic context for the landing site. This context is of utmostimportance for the interpretation of the geophysical data gathered by Netlander.

Task 3: A priori model of the evolution of the planet and thermodynamical state: This task willconsist in the determination of the parametric relation between the present size of the main Martianreservoir (core, mantle, crust), the present temperature profile and the different thermal evolutionscenario, including accretion. The impact of different regimes of convection in the past will be studied,as well as the impact of the presence, absence and depth of the different transitions of the Martianmantle in the convection regime. Simulation will be performed in 3D geometry.

Task 4: Equation of states and mineralogy : This task will consist in defining the parameters, whichwill be actually accessible in order to describe the inner structure of Mars. The goal is to provide,before the launch of the mission, a set of a priori models, which will be ready at hand to interpret thedata as soon as they will be acquired, and transmitted to Earth. The models, including error bars, willconsist in profiles of density, elastic, and electrical conductivity. They will be constructed afterthermodynamical principles, equation of states, and on a compilation of high pressure-high temperatureexperiments. Emphasis will be given to the relationshix between the values of geophysical parameters,Mars therms, and mineralogy. The derived models will be validated by checking their consistency withthe results obtained by previous Martian missions, in collaboration with tasks 5 and 7.

Task 5: orbital dynamics and In terior/atmosphere interaction : This task will consist in thecomplete description of the orbital dynamic of the planet, including tides, precession, nutation and theirrelation ship with the internal structure. The impact of mass exchange between the Polar caps andatmosphere will be modeled. M odeling of the pressure and wind will be performed by a 3D GlobalCirculation Model and used as input for the computation of the continuous excitation of Normal modesof Mars.

Task 6: Cryolithosphere structure This task will consist first in a compilation of existing softwaresnecessary for the analysis and interpretation of data that bear information on the cryolithospherestructure. Emphasis will in particular be put on the development of the GPR softwares, by usingsynergies in prospecting seismology. The second objective of this task is to develop and assessmethods for joint interpretation of these data.

Task 7: geophysical methods This task will consist first in a compilation of existing softwaresnecessary for the analysis and interpretation of the NL geophysical and geological package. Suchcompilation will extend already existing ones, such as those performed by Orpheus or Geoscope forseismology. A special care will be put on some specificities of Mars, such as the importance of thecrustal corrections in the propagation of surfaces waves. The second objective of this task is to developand assess methods for joint interpretation of data from these two packages.

Task 8: Tectonics and Seismicity This task will be linked to task 1 and task 2. It will consist in adetailed analysis of the Martian surface, in order to map faults systems and to constrain the past andpresent seismic activity . It will then provide detailed information on the stress system on Tharsis, andit will link these orientations to the chronology of Tharsis from crater counting methods.
