А life-cycle of space objects simulation have been illustrated. The probabilistic model of transitions was constructed. The system of Kolmogorov equations defining the flow state lifecycle model probabilities was proposed. The duration of iterations and probability of defects for each phase of lifecycle for real space elaboration was investigated. The numerical solution for life cycle for different source data was investigated. The methods for risk reduction was proposed.
