A new method is developed to determine the structure of telluric planetary interiors. It is based on the joint inversion of
data from in situ˙geophysical experiments and laboratory measurements. We infer conditional probability densities of the
parameters governing˙the internal structure by stochastic inversion. This multi-parameters approach is quite generic and
can˙be applied to any telluric planet. We illustrate it here with˙simulated data of the future Netlander˙mission to Mars. The
simulated data come from the electromagnetic, geodetic and seismological experiments. This approach is free of any a priori
assumption regarding the˙temperature profile of the planetary mantle. From the inferred conditional probabilities we estimate
the mineralogy and the temperature profile for the mantle as well as the sulfur weight fraction and the temperature profile
for a possible liquid core.
