Abstract : In-situ observation of several comets by spacecraft, the collection and delivery to Earth of dust from a cometary coma, remote sensing of comets, and comparison with the properties of interplanetary dust, some of which is cometary, collected at Earth, have provided many new insights to the composition and structure of cometary dust. These investigations have raised new, more detailed questions, suggesting future directions for comet research.
