SESAME (Surface Electrical Sounding and Acoustic Monitoring Experiments) Three instruments measure properties of the comet's outer layers. The Cometary Acoustic Sounding Surface Experiment (CASSE) measures the way in which sound travels through the surface. The Permittivity Probe (PP) investigates its electrical characteristics, and the Dust Impact Monitor (DIM) measures dust falling back to the surface.


Principal Investigators:
CASSE: Martin Knapmeyer (PI for the SESAME consortium), German Aerospace Center, Institute of Planetary Research, Asteroids and Comets, Berlin, Germany
DIM: Harald Krueger Max-Planck-Institute for Solar System Research, Göttingen, Germany
PP: Walter Schmidt, Finnish Meteorological Institute, Helsinki, Finland
