Real time expert systems have been developed by the National Aeronautics and Space Administration (NASA) to monitor telemetry data from the Space Shuttle. These systems have been used during Space Shuttle flights. This represents the first use of expert systems to make flight decisions in a real space mission. This paper describes the requirements that led to the development of the expert system, the architecture used to obtain real-time performance, and the payoffs from the system.
