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 27/04/2004 2004 EUG MAGE Meeting

Tasks activities (see MAGE proposal) 27/04/2004

Task 1: A p riori model of the Tharsis Area:

This task will consist in the determination of the lithospheric structure by using all type of data from the MGS NASA. Further constraints will be obtained by the Gamm a Ray experiment onboard the 2001 Mars Odyssey orbiter. Such approach will consist in wide mu lti-disciplinary approach for constraining this geologic province of Mars, which is very likely constraining strongly the thermal evolution of the planet.

Task 2: Geologic charac terization of the landing sites :

This task will consist in the geomo rphologic investigation of the landing site. This will be based on interpretation of orbital remote sensing data from other miss ions. In particular, imaging data (Viking Orbiter, MOC onboard MGS, Themis onboard 2001 Mars Odyssey) and topographic data (MOLA onboard MGS) and latter Mars Express will be used for this task, as they provide the

geologic context

for the landing site. This context is of utmost imp ortance for the interpretation of the geophysica l data gathered by Netlander.

Task 3: A priori model of the evolution of t he planet and thermody namical state:

This task will consist in the determination of the parametric relation between the present size of the main Martian reservoir (core, mantle, crust), the present temp erature profile and the different thermal evolution scenario, including accretion. The imp act of different regimes of convection in the past will be studied, as well as the imp act of the presence, absence and depth of the different transitions of the Martian mantle 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, which will 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 the data as soon as they will be acquired, and transmitted to Earth. The models, including error bars, will consist in profiles of density, elastic, and electrical conductivity. They will be constructed after thermodynamical principles, equation of states, and on a compilation of high pressure-high temperature experime nts. Emphasis will be given to the relationshix between the values of geophysical parameters, Mars therms , and mineralogy. The derived mo dels will be validated by checking their consistency with the results obtained by previous Martian missions, in collaboration with tasks 5 and 7.

Task 5: orbital dynamic s and In terior/atmosph ere interaction :

This task will consist in the complete description of the orbital dynamic of the planet, including tides, precession, nutation and their rela tion ship with the internal structure. The imp act of mass exc hange between the Polar caps and atmosphere will be mo deled. M odeling of the pressure and wind will be performed by a 3D Global Circulation Model and used as input for the computation of the continuous exc itation of Normal mo des of Mars.

Task 6: Cryolithosphere structure

This task will consist first in a comp ilation of existing softwares necessary for the analysis and interpretation of data that bear information on the cryolithosphere structure. Emphasis will in particular be put on the development of the GPR softwares, by using synergies in prospecting seismology. The second objective of this task is to develop and assess methods for joint interpretation of these data.

Task 7: geophys ical methods

This task will consist first in a comp ilation of existing softwares necessary for the analysis and interpretation of the NL geophysical and geologica l package. Such compilation will extend already existing ones, such as those performed by Orpheus or Geoscope for seismology. A special care will be put on some specificities of Mars, such as the imp ortance of the crustal corrections in the propagation of surfaces waves. The second objec tive of this task is to develop and assess methods for joint interpretation of data from these two packa ges.

Task 8: Tectonics and Seismicity

This task will be linked to task 1 and task 2. It will consist in a detailed analysis of t he Martian surface, in order to map faults systems and to constrain the past and present seismic activity . It will then provide detailed information on the stress system on Tharsis, and it will link these orientations to the chronology of Tharsis from crater counting me thods.
