This paper describes the application of an automated planning and scheduling system to the NASA Earth Orbiting 1 mission. The planning ASPEN, is used to autonomously schedule the daily activities of the satellite. The satellite and operations constraints are encoded within a software model used by the planner. This paper includes a description of the planning system and the associated modeling language. We then discuss how we encoded the 1 spacecraft operations with the modeling language. We conclude with a description of the end-to-end planning system as we envision it for INTRODUCTION Automated technologies show great promise in reducing operations costs by increasing autonomy of mission operations. The Artificial Intelligence (AI) Group at the Jet Propulsion Laboratory' has been on a system called ASPEN (A Scheduling and Planning Environment). ASPEN et al. is a modular, application framework based on AI techniques [Allen et al. 1990, Fox 1994], which is capable of supporting...
