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
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
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
