Autonomous Science on the EO-1 Mission
In mid-2003, we will fly software to detect science events that will drive autonomous scene selectionon board the New Millennium Earth Observing 1 (EO-1) spacecraft. This software will demonstrate the potential for future space missions to use onboard decision-making to detect science events and respond autonomously to capture short-lived science events and to downlink only the highest value science data.
Heterarchical clustering in mutually constraining but disjunct feature spaces
We introduce a general type of optimization algorithm that infers data models relating two or more disjunct feature spaces, representing different aspects of a set of objects.
The Techsat-21 autonomous space science agent
In this paper we discuss how these AI technologies are synergistically integrated in a hybrid multi-layer control architecture to enable a virtual spacecraft science agent.
Clustering algorithm for mutually constraining heterogeneous features
We introduce a general type of optimization algorithm which infers data models relating two different but intertwined types of information about each of a set of objects.
Io's heat flow: accounting for unexpected sources
Explore the source record for details and available documents.
Upper bound on Io's heat flow
Analysis of the temperatures and areas of Io's thermal anomalies yields an upper bound on the total heat flow.
Thermal signature, eruption style, and eruption evolution at Pele and Pillan on Io
The Galileo spacecraft has been periodically monitoring volcanic activity on Io since June 1996, making it possible to chart the evolution of individual eruptions.
Clustering algorithm for mutually constraining heterogeneous features
We introduce a general type of optimization algorithm which infers data models relating two different but intertwined types of information about each of a set of objects.
The Techsat-21 autonomous sciencecraft constellation
This paper talks about the techsat-21 autonomous sciencecraft constellation.
How do we make rovers better geologists at Mars?

A demonstration of robust planning, scheduling, and execution for the Techsat-21 autonomous sciencecraft constellation
The paper talks about the planning, scheduling, and execution framework used in ASC (Autonomous Sciencecraft Constellation).
Onboard science analysis and replanning for increased science return
The Autonomous Sciencecraft Constellation (ASC) experiment, which will fly onboard the Air Force's TechSat-21 constellation, will demonstrate the use of onboard science analysis and replanning to increase science return.
Goal-directed scientific exploration using multiple rovers
This paper describes an integrated system for coordinating multiple rover behavior with the overall goal of collecting planetary surface data.
The Techsat-21 Autonomous Sciencecraft Constellation demonstration
The Autonomous Sciencecraft Constellation flight demonstration (ASC) will fly onboard the Air Forces's TechSat-21 constellation. Demonstration of its capabilities in a flight environment will open up tremendous new opportunities in planetary science, space physics, and earth science that would be unreadable without this technology.
Silicate cooling model fits to Galileo NIMS data of volcanism on IO
The Near Infrared Mapping Spectrometer (NIMS) has obtained spectra of volcanoes on the surface of the jovian satellite Io.
