| Summary: | : The transient variations of at the surface of a planet has a primary source, the interaction between the environment of the and solar radiation, and a secondary source, the electric currents induced the conductive The continuous recording of the time variations of the magnetic at the surface Mars by means three magnetometers landers both the interns/ structure of Mars and the dynamic its ionized environment. , The depth of penetration of an electromagnetic wave in a conductive medium depends on both the period wave and the of the medium. The larger the period and the the greater the depth of penetration (skin effect). The high frequency spectrum will therefore enable one to estimate the in the uppermost kilometers of the planet, and to give information about the presence (or absence) of liquid water under the permafrost. The low frequency spectrum of the transient variations will give information on the presence (or absence) of sharp variations in the in the uppermost hun. |
