Model-based spacecraft safety and mission assurance is a systematic approach to ensuring the safety and reliability of a spacecraft mission using modeling and simulation tools. It involves developing and testing mathematical models of the spacecraft and its subsystems, and using these models to identify and analyze potential hazards, failures, and risks.
The goal of model-based spacecraft safety and mission assurance is to ensure that a spacecraft is designed and operated in a way that minimizes the risk of mission failure and protects both the spacecraft and its crew or payload. This approach involves a range of activities, including:
Key Activities:
-
▶ Developing and validating models of the spacecraft and its subsystems, such as propulsion, power, communication, and navigation systems.
-
▶ Using these models to simulate and analyze the performance of the spacecraft under various scenarios, including normal operation, off-nominal events, and failure modes.
-
▶ Identifying potential hazards and risks associated with the spacecraft and its subsystems, and developing mitigation strategies to address them.
-
▶ Performing verification and validation of the models and the associated software to ensure that they accurately represent the spacecraft and its behavior.
-
▶ Using the models and simulation tools to support spacecraft operations, including monitoring and control of the spacecraft during launch, in-orbit operations, and re-entry.
-
▶ Continuously improving the models and associated processes based on feedback from mission experience, lessons learned, and advances in technology.
