This paper aims at an understanding of the ejecta cloud dynamics, which is crucial to the planning of the ongoing AIDA mission.
An informative dynamic model has been built to synthesize all relevant forces based on comprehensive analysis.
A full-scale simulation was organized towards the response of Didymos to DART impact and the following month-long evolution of the ejecta cloud.
Some interesting results about the post-impact physics have been uncovered according to the simulation.
