27/04/ EUG MAGE Meeting Team n Planetology team in Saint Maur des Fossés u P. Lognonné, M.Wieczoreck, J. Gagnepain-Beyneix u Other scientists in IPGP Jussieu ( B.Bourdon, S.Labrosse, primitive Mars), C.Jaupart’s team ( convection), Seismo lab, etc n 2 MAGE post-docs u Amir Khan ( 4/2003->8/2004) u Peter van Thienen (3/2004-2/2006) n 2 PhD Students u H. Chenet ( -> 12/2003) ( Moon seismology ) u V.Belleguic (->12/2004) ( Mars Gravimetry and Topography ) u M. Le Feuvre ( 9/2004 -> ) ( Moon and Mars Chronology ) u Ana Rita Baptista ( 1/2005 -> ) ( Mars magnetosphere and radiative environement )

27/04/ EUG MAGE Meeting Planetary Cores M. Wieczorek, A. Khan, S.Labrosse et P. Lognonné n Science Objectives u Planetary Formation processes u Present size, state and mineralogy n Data: LLR, Sismo Apollo, Gravimetry LP n Some results: u Moon: confirmation of a liquid core, estimation of the temperature u Mars: detailed analysis and theory of tidal signals

27/04/ EUG MAGE Meeting Crust and Martian lithosphere M. Wieczoreck, V. Belleguic, P. van Thienen et P. Lognonné n Science objectives u Crustal formation,evolution, impact and volcanic comparative tectonics u Propagation of seismic waves in the Martian crust. n Data: MGS ( gravimetry, altimetry) n results: u Crustal thickness. Estimation of the fraction of primary crust in the southern hemisphere u Estimation of the thickness of the elastic lithosphere and of the density of volcanoes

27/04/ EUG MAGE Meeting Lunar crust and Mantle A.Khan, J. Gagnepain, P. Lognonné, H.Chenet ( ISAS, Japan) n Science objectives: u Crustal thickness u Mineralogical and temperature composition of the mantle. n Data: Apollo, LP ( gravimetry, altimetry) n Results: u New estimate of the crustal thickness u Better agreement with geochemistry u New estimate of the U content in the mantle.

27/04/ EUG MAGE Meeting Mineralogical and temperature results Seismic velocities

27/04/ EUG MAGE Meeting New research orientations n Primitive Mars and Mars evolution u more in P. van Thienen presentation u Effect of atmosphere and volatiles on long term convection n Determination of a new cratering chronology for the Moon and Mars(Le Feuvre and Wieczoreck) n Magnetosphere, magnetic crust and radiation ( collaboration with CETP and Portugal) ….
