Description
In recent years, several metrics have been proposed to quantify the impact of a mission on the space debris environment. These emerging approaches are meant to go beyond the analysis of compliance of missions with space debris mitigation guidelines, by considering additional aspects such the short-term impact of a mission on its neighbours and the evolution of the environment.
Our formulation for such analysis is a risk metric that measures the fragmentation risk associated to a spacecraft, i.e. the collision probability and the severity of the potential fragmentation. For the computation of the collision probability, the data from MASTER is used to obtain the flux of debris at the orbit location and derive the distribution of the flux as a function of the object size. In order to allow for almost real-time computation, collision probability maps are generated where the relevant data for the simulation is store to avoid direct calls to the MASTER software.
The presentation will give an overview of the computation pipeline and present some typical applications.
