a) Numerical geometry model of the SESAME-PP instrument and its conducting environment. The red shape is the body of the lander combined with the landing gear (element 13). The body is rotated by 11.2° with respect to the landing gear. The blue shapes are the conductive plates linking the legs of the lander to the feet (elements 1, 5, and 9). The green shapes are the ice screws on each foot (elements 2, 6, and 10). The yellow shapes are the guards of the electrodes (elements 3, 7, and 11). The dark gray shapes represent the soles of the electrodes (elements 4, 8, and 12). The pink shape is the MUPUS-PEN electrode and guard (elements 16 and 17). Lastly, the black shape is the APXS electrode (elements 14 and 15), once deployed under the balcony. Not represented on this numerical model are the harpoons located under the body of the lander (elements 18 and 19). b) Zoom on one of the feet of the lander.
