A Probabilistic Modeling Framework for Transient Debris Outcomes in Low Lunar Orbits
Abstract
This work presents a novel probabilistic framework for the assessment of orbital debris fragment outcomes in the low lunar orbit (LLO) regime over time horizons ranging from a few hours to a hundred days after a debris generation event. The framework develops continuous distributions for the probability of sinking (lunar collision) and non-sinking over these transient time horizons, building upon NASA's Standard Breakup Model to provide insights into the variations in the likelihood of debris outcomes across the LLO regime and offering an alternative to computationally expensive Monte Carlo simulations. The effects of perturbative forces such as solar radiation pressure are used to assess the realization of debris outcomes over varying time horizons, providing an analytical framework that bounds the likelihood of each outcome. Results indicate variations in the probability of sinking over short time horizons depending on the originating location of the debris generation event, as well as a link between the physical characteristics of fragments and their likelihood of sinking over longer time horizons. The future incorporation of this framework into broader-scale orbital environment models, mission risk assessment procedures, and policy development are briefly discussed.
