Laboratory dielectric constant determination for planetary surface characterization
Résumé
A program of dielectric constant determination on various analogues, over a large range of frequencies and porosities, is under development in relation with the interpretation of Rosetta spacecraft observations. The analogues are meteoritic samples (compact and powdered), likely to be representative of the asteroids that have already been flown-by and of the cometary nucleus that is to be encountered. First results have already been obtained for asteroid Steins.
