session 3

Title

Environment Modelling and Risk Assessment

type

oral

Description

This session will cover the modelling of the space debris environment and the assessment of associated risks. Topics will include collision risk analyses, estimations based on population models and deterministic catalogues, as well as studies on the reconstruction of break-up and fragmentation events. The session will also address validation of models through observations and laboratory experiments, aiming to improve the prediction of orbital environment evolution. It will also examine methods for assessing orbital capacity and congestion, including indicators for orbital slot usage, and impact of allocation strategies on population dynamics. The combined perspective of environmental modelling and capacity management provides a comprehensive view of the long-term sustainability of the orbital environment.
