Exploring the Mars Mantle and Ionized Environment: Insights from Forward and Inverse Modelling

This paper presents forward and inverse modelling of the Martian mantle and ionized environment. Key inputs include mineralogy, crust thickness, core parameters, and temperature profiles, yielding outputs such as density variation, seismic potential, and electrical conductivity. Additionally, we detail electromagnetic impedance determination through advanced algorithms. The work contributes to understanding Mars' geological framework and ionized ambiance, providing critical insight for ongoing and future Martian exploration efforts. Papers related to these studies are in preparation and submission for publication.

Presentation Transcript

  1. Mars mantle: forward modelling • Inputs: mineralogy, crust thickness and average density, core radius and mass, temperature profile, pressure gradient. • Outputs: variation with depth of the density, seismic potential, and electrical conductivity. • paper submitted for publication at JGR • see poster Network activity: MINT Working Group contribution

  2. Mars mantle: inverse modelling • Inputs: global geodetic parameters, variation with depth of the seismic potential and electrical conductivity, crust thickness and core radius. • Outputs: mineralogy, crust average density, core mass, temperature profile, pressure gradient. • Paper in preparation • see poster Network activity : MINT Working Group contribution

  3. Mars conductive structure from network magnetic data • Determination of the electromagnetic impedance Z(w) by means of space-time frequency filters*. • MCMC algorithms for Z(w) inversion Network activity: CETP, LPCE, UMLV, GGKI Sopron The hungarian PhD student got killed in a car crash by the end of october 2003.

  4. Mars ionized environment: forward modelling • Hybrid 3-D forward modelling of the Mars ionized environment from the solar wind down to 500 kilometers above the Mars surface (R. Modolo thesis, G. Chanteur supervisor). • To be coupled with a ionospheric model, at present under development. • Paper in preparation (hybrid model) • see poster The model is a tool to be used in frame of the Post-Doc activities Network activity: Working group on Mars ionized environment studies

  5. Post-Doc position • Use both MGS magnetic recordings and the Mars environment model to get information on the magnetic external sources in the Mars ionized environment. • Few candidates, no Post-Doc for the time being
