This level of interaction will improve the quality and efficiency of data collection, analysis and interpretation. Such rapid availability of information will also aid in fast decision-making needed during fires and other natural disasters. Remotely piloted aircraft similar to Pathfinder could spend long periods of time over the ocean, monitoring storm developments to provide more accurate predictions of hurricanes. These aircraft also could be used to monitor major croplands, forests and other large, remote expanses to provide early warning of crop damage or fires. Additional technologies considered by the joint NASA-industry alliance include lightweight materials, avionics, sensor technology, aerodynamics, and other forms of propulsion suitable for extreme altitudes and duration.
Pathfinder is one of several remotely piloted aircraft being evaluated under the program.
The program focuses on developing technologies required to operate subsonic unpiloted aircraft at high altitude for long-duration. The most extreme mission envisioned for solar-powered aircraft would reach altitudes of 100,000 feet for science and commercial application missions. Pathfinder is a flying wing with a span of 99 feet. A backup battery system can provide power for up to five hours to fly the craft after sundown.
