The camera has a variety of potential science and commercial applications, such as documenting flood surges, geologic features and crop stress, according to Wegener. Pathfinder recently set an altitude record for propeller-driven flight of over 71,500 feet. We beat our altitude milestone by 6,500 feet in the first two flights this summer and demonstrated the capability for science mission demonstrations in a remote, tropical location. The program focuses on developing technologies required to operate subsonic unpiloted aircraft at high altitude for long-duration flights. Pathfinder is a flying wing with a span of 99 feet.
Small pods extending below the wing's center section can carry a variety of scientific sensors.
Solar arrays on the upper wing surface can provide as much as 7,200 watts of power at high noon on a summer day to power the craft's six electric motors and other electronic systems. A backup battery system can provide power for up to five hours to fly the craft after sundown.
