Ever since the beginning of the space age satellites and space probes performed space dust measurements. The goal was, initially, to quantify the hazard of meteoroid impacts onto space vehicles. Samples returned to Earth by the Apollo astronauts demonstrated that the lunar surface is peppered by microcraters generated by high speed impacts of cosmic dust particles. Their analysis provided a measurement of the flux of interplanetary dust particles. The later goal of dust measurements was the exploration of the dust environments throughout interplanetary space, within planetary systems, and, today, it is to analyze planetary bodies from which dust particles originate. The development of instrument swent from simple and small but noisy microphone detectors, over large and reliable multi-coinc
