  1. IPGP Mage activities

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

  3. Planetary Cores M. Wieczorek, A. Khan, S.Labrosse et P. Lognonné • Science Objectives • Planetary Formation processes • Present size, state and mineralogy • Data: LLR, Sismo Apollo, Gravimetry LP • Some results: • Moon: confirmation of a liquid core, estimation of the temperature • Mars: detailed analysis and theory of tidal signals 2004 EUG MAGE Meeting

  4. Crust and Martian lithosphereM. Wieczoreck , V. Belleguic, P. van Thienen et P. Lognonné • Science objectives • Crustal formation,evolution, impact and volcanic comparative tectonics • Propagation of seismic waves in the Martian crust. • Data: MGS ( gravimetry, altimetry) • results: • Crustal thickness. Estimation of the fraction of primary crust in the southern hemisphere • Estimation of the thickness of the elastic lithosphere and of the density of volcanoes 2004 EUG MAGE Meeting

  5. Lunar crust and MantleA.Khan,J. Gagnepain, P. Lognonné, H.Chenet ( ISAS, Japan) • Science objectives: • Crustal thickness • Mineralogical and temperature composition of the mantle. • Data: Apollo, LP ( gravimetry, altimetry) • Results: • New estimate of the crustal thickness • Better agreement with geochemistry • New estimate of the U content in the mantle. 2004 EUG MAGE Meeting

  6. Mineralogical and temperature results • Seismic velocities 2004 EUG MAGE Meeting

  7. New research orientations • Primitive Mars and Mars evolution • more in P. van Thienen presentation • Effect of atmosphere and volatiles on long term convection • Determination of a new cratering chronology for the Moon and Mars(Le Feuvre and Wieczoreck) • Magnetosphere, magnetic crust and radiation ( collaboration with CETP and Portugal) …. In addition to MAGE activities 2004 EUG MAGE Meeting
