Scientific Issues and Detection Schemes on the Dust Characteristics of Main Belt Comets

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.
