A new modelling scheme of the structure of telluric planetary interiors is presented. The method is based on the joint inversion of data sets provided by in situ geophysical experiments and laboratory results. We infer conditional probability densities of the parameters governing the internal structure by stochastic inversion of the model conditioned on the data set. Although this multi-parameters approach is quite generic and can therefore be applied to any telluric planet, we illustrate it here with simulated data of the future Netlander mission to Mars. The synergy between the three experiments of electromagnetic sounding, geodesy and seismology is emphasized as being the cornerstone of a new model of the martian internal structure. This approach is exempt of any a priori assumption regarding the temperature profile. From the inferred conditional probabilities we estimate the mantle mineralogy, temperature profile as well as mantle mass.
