Measuring the permittivity of the surface of the Churyumov-Gerasimenko nucleus: the PP-SESAME experiment on board the Philae/ROSETTA lander
Résumé
The Permittivity Probe (PP-SESAME) on-board the Philae Lander of the ROSETTA mission will de- termine the complex permittivity of the surface of the Churyumov-Gerasimenko nucleus and monitor its variations with time. Doing so, it will provide unique insight into the composition and activity of the comet. In this paper, we present the method we have devel- oped to analyze PP-SESAME active measurements. This method will be tested in May 2014 with a replica of the instrument in the giant ice cave system of Dachstein, in Austria.
