Abstract :
An Autonomous Science Agent has been flying onboard the Earth Observing One spacecraft since 2003. This software enables the spacecraft to autonomously detect and responds to science events occurring on the Earth such as volcanoes, flooding, and snow melt. This agent includes artificial intelligence software systems that perform science data analysis, deliberative planning, and run-time robust execution. This software is in routine use to fly the EO-1 mission. In this paper we discuss the architecture used to integrate these systems and lessons learned from its multi-year flight on EO-1.
