The proper and comprehensive identification of system-level failure mode during risk assessment for space systems has difficulty due to complexity of system-level interactions which involves multi-physics and dynamic phenomena. The study considers potential system-level failure mode identification by using the system-level modeling and simulation based approach to risk assessment for space systems. The proposed approach is based on the use of the modeling language Modelica, an equation-based object-oriented modeling language which allows acausal modeling for complex cyberphysical systems. Modelica has an important capability of modeling for system level interactions which involves multiphysics phenomena. Based on the trial results of this proposed approach to the space systems, technical feasibility and expected effect of this approach will be discussed in this paper.
