Dielectric properties of Mars' surface: Proposed measurement on a Mars lander

Recent studies of missions to Mars (MESUR by NASA and Marsnet by ESA) have suggested the development of semihard landers. One type was to be extremely basic, consisting mainly of a meteorological package, but with the possibility of other small, low-mass, low-power instruments. In particular, this type of lander was also considered for the exploration of the polar regions. Two methods to investigate the surface material at the landing site are discussed. Both measure the dielectric constant epsilon of the ground material. This information can then be used to elucidate the surface composition and structure. The determination of the permittivity would be of high scientific value, especially in the case of a landing on the polar ice.
