Real-time AI is gaining increasing attention for applications in which conventional software methods are unable to meet technology needs. One such application area is the monitoring and analysis of complex systems. MARVEL (multimission automation for real-time verification of spacecraft engineering link), a distributed monitoring and analysis tool with multiple expert systems, was developed and successfully applied to the automation of interplanetary spacecraft operations at the Jet Propulsion Laboratory (JPL) of the National Aeronautics and Space Administration (NASA). In this chapter, we describe MARVEL implemen-tation and validation approaches, the MARVEL architecture, and the specific benefits that were realized by using MARVEL in operations. MARVEL is an automated system for telemetry monitoring and analy-sis. It has been actively used for mission operations since 1989. It was first deployed for the Voyager spacecraft’s encounter with Neptune and has remained under incremental development since this time, with
