APXS An alpha proton X-ray spectrometer will study the chemical composition of the landing site and how it changes as the comet approaches the sun. CIVA The comet nucleus infrared and visible analyzer will use six cameras to take vpanoramic pictures of the comet’s surface. CONSERT Radio sounding of the comet will study its internal structure. COSAC An evolved gas analyzer will detect and identify complex organic molecules.Ptolemy It will determine isotopic composition of the lighter elements of hydrogen, carbon, nitrogen and oxygen to understand their geochemistry. MUPU Sensors will collect data on surface and subsurface properties. ROLIS It will provide close-up images of the landing site. ROMAP Magnetometer and plasma monitor will study the comet’s magnetic field and plasma environment. SD2 It can drill almost 8 inches into the surface, collecting samples to deposit into ovens and microscopes for analysis. SESAME Surface electric sounding and acoustic monitoring experiments will gather data on the mechanical and electrical properties of the comet. 12 345678910 1 2 3 4 5 6 7 8 9 10 10 10 10
