- •
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.
