A knowledge system which utilizes artificial intelligence technology to automate a subset of real time mission operations functions is described. An overview of spacecraft telecommunications operations at the Jet Propulsion Laboratories (JPL) highlights requirements for automation. The knowledge system, called the Spacecraft Health Automated Reasoning Prototype (SHARP), developed to explore methods for automated health and status analysis is outlined. The advantages of the system were demonstrated during the spacecraft's encounter with the planet Neptune. The design of the fault detection and diagnosis portions of SHARP is discussed. The performance of SHARP during the encounter is discussed along with issues and benefits arising from application of knowledge system to mission operations automation.
