Integrated System Health Management (ISHM) is a capability that focuses on determining the condition (health) of every element in a complex System-of-Systems or SoS (detect anomalies, diagnose causes, predict future anomalies), and on providing data, information, and knowledge (DIaK) to control systems for safe and effective operation. This capability is currently done primarily from ground by teams of people, but needs to be automated to a higher degree to enable NASA's new Exploration Mission (long term travel), while increasing safety and decreasing life cycle costs of spacecraft (vehicles, platforms, bases) and ground systems (test stands, launch systems, mission control). This paper describes an on-going effort (project) to implement credible ISHM capability in NASA's ground systems and spacecraft. The project objective is to achieve end-to-end ISHM for the J-2X Engine and the test facility, which can be used to carry out a more effective engine test program. Also, with the credibility gained in this ground testing application, it is plausible that some results could be used to enhance the flight engine's ISHM capability. In the first year, the test stand/engine ISHM will be implemented at a medium functional capability level (FCL), that is, the extent of DIaK embedded will not be exhaustive, but will be enough to demonstrate feasibility and evaluate benefits. Validation will be done using simulated and historical data initially. Data from new tests will be used if available. This paper describes interim results.
