To investigate the resilience and sustainability of the global space environment, a Multi-layer Temporal Network Model (MTN) is proposed in this paper. The idea of the network model is to study the relationships among groups of objects in space by studying the topology and dynamics of an equivalent network where each node is a group of objects and the link is modelling the relationship. “Multi-layer indicates different functionalities among the space objects, such as the physics and information, etc. Currently, only physical layer of MTN is considered. By comparing with the simulation results from existing space environment model, the correctness of the network model is first verified. Some experiments are performed to demonstrate the basic functionalities of the proposed MTN.
