  • Orbital charged debris clouds evolution phase was defined as sphere, spheroid, rope, spiral, spreading and shell, based on the geometry shape and debris density in the evolution from the initial breakup point to the final coverage of Earth. The shape character and the key drive sources of each phase are addressed. The perturbation of charged debris impacted by electromagnetic field in each phase was analyzed. The evolution different between charged debris and uncharged was compared. The separate velocity decides the shape and size during the sphere phase, and the repulsion between debris accelerates separation velocity. The charged debris and uncharged is nearly accordant from spheroid phase to sphere. The charged debris evolution speed would accelerate if debris' electric charge polarity is positive and decelerate if polarity is negative. Based on the analysis that the perturbation impacted by electric field was equivalent to the change of gravity, the time mark between the phases was given and calculation formula was listed. The uncharged debris clouds and charged debris clouds evolution phase were visualized though computer simulation, that verified the rationality of phase definition and electromagnetic field perturbation analysis.
