Sensor Webs for Science: New Directions for the Future

By Rob Sherwood and Steve Chien

Abstract

Sensor webs for science have evolved considerably over the past few years. New breakthroughs in onboard autonomy software have paved the way for space-based sensor webs. For example, an autonomous science agent has been flying onboard the Earth Observing One (EO-1) Spacecraft for several years. This software enables the spacecraft to autonomously detect and respond to science events occurring on the Earth. The package includes software systems that perform science data analysis, deliberative planning, and runtime robust execution of the generated plans. This software has demonstrated the potential for space missions to use onboard decision-making to detect, analyze, and respond to science events, and to downlink only the most valuable science data. This paper will briefly summarize this experiment as well as describe how the software has been used in conjunction with other satellites and ground sensors to form an autonomous sensor-web. In addition to these applications, which represent the current state of the art for autonomous science and sensor webs, we will describe the future research and technology directions in both Earth and Space Science. Several technologies for improved autonomous science and sensor webs are being developed at NASA. This paper will present an overview of these technologies. Each of these technologies advances the state of the art in sensorwebs in different areas, allowing for increased science within the domain of interest. Demonstration of these sensorweb capabilities will enable fast responding science campaigns of both spaceborne and ground assets
