Analysis of Space Station Operations in the Space Debris Environment.
Abstract
Analysis of Space Station operations in the space debris environment involved the conceptualization and development of a simulation model to provide initial estimates concerning Space Station survivability and fuel requirements. An initial review of recent literature indicated the relative insensitivity of satellite-of-interest collision probability calculations to modeling debris density with varying complexity. In addition, the literature identified that the debris population unable to be detected by current means, the rate of unintentional explosions and inter-object collisions, and the dynamics of these occurrences are important system parameters on which little is known. Conceptual model elements significantly affecting the space debris population and lending themselves to modeling were included in the discrete-event SLAM simulation model developed. The model simulated space debris environment dynamics up to Space Station system maturity. Model results indicated that at least one collision could occur within the first 29 years of Space Station operations. The results stress the need for greater consideration of the survivability of large, long-term spacecraft in such an environment, and for greater ground-tracking or on-board debris detection capabilities.
