The New Millennium Program (NMP) Space Technology 6 (ST-6) Autonomous Sciencecraft Experiment (ASE) will fly two scene classifiers on the Earth Orbiting 1 (EO-1) spacecraft in the fall of 2003, and will demonstrate autonomous, onboard processing of Hyperion imager 0.4-2.4 micron hyperspectral data, and autonomous, science-driven planning and acquisition of subsequent observations. ASE is an experiment to meet NASA's call for systems with reduced downlink and onboard data processing to enable autonomous missions. ASE software is divided into three classes: (1) spacecraft command and control; (2) an onboard planner (CASPER); and (3) modular science algorithms, which are used to process raw data to search out specific features and spectral signatures. The ASE Science Team has developed scene classifiers to detect thermal emission in both day and nighttime Hyperion data, and are continuing to develop other scene classifiers for ice, snow, water and land for future release and flight on EO-1. Once uploaded, the thermal scene classifier effectively turns the EO-1 spacecraft into an autonomously operating and reacting volcanic activity detector. It is possible to envision such a capability on spacecraft observing volcanism on Io and Triton, autonomously identifying and classifying activity, identifying sites deserving of closer scrutiny, and retasking the spacecraft to observe them, thus fulfilling NASA's goal of fully-autonomous, science-driven spacecraft.

This work was carried out at the Jet Propulsion Laboratory-California Institute of Technology, under contract to NASA.
