MIDAS (Micro-Imaging Dust Analysis System):
Studies the dust environment around the asteroids and comet. It provides information on particle population, size, volume and shape.
The Orbiter's scientific payload includes 11 experiments, in addition to the Lander. Scientific consortia from institutes across Europe and the United States have provided these state-of-the-art instruments. All of them are located on the side of the spacecraft that will permanently face the comet during the main scientific phase of the mission.
