An Autonomous Science Agent has been flying onboard the Earth Observing One Spacecraft since 2003. This software enables the spacecraft to autonomously observe, detect, and respond to science events occurring on the Earth such as volcanoes, flooding, and sea ice breakup. This software, called the Autonomous Sciencecraft Experiment (ASE), includes AI software systems that perform science data analysis, deliberative planning, and run-time robust execution. ASE is in routine use controlling the EO-1 mission and has successfully acquired over a thousand images. More recently ASE has been integrated with dozens of other assets to form an earth observing sensorweb to to autonomously track volcanoes, floods, and wild fires. In this talk we describe the ASE software, how autonomous systems enable revolutionary new missions of space exploration, and areas of AI research central to space exploration.
