Abstract: To study the origin and formation of Main Belt Comets (MBCs), the characteristics of non-active period MBCs, as well as the relationships between MBCs and other comets and asteroids are studied. It emphasizes the need to develop an in-situ detection method capable of covering the characteristics of dust particles should be developed. In light of the upcoming Chinese Tianwen-2 mission, the authors propose an integrated composite detection method for non-contact measurement was proposed based on an analysis of the relationship between the characteristics of dust in MBCs and scientific problems, which is capable of non-contact measurement of MBCs’ ejected dust particle size, velocity, momentum, morphology, and flux without changing the original characteristics of the dust. This design has been applied to the engineering practice of the Tianwen-2 mission.
