NASA's Dryden Flight Research Center in California has partnered with General Atomics Aeronautical Systems (GA-ASI) to demonstrate technologies that will expand the capabilities of remotely operated, unmanned aircraft to perform high-altitude Earth science missions. GA-ASI developed a version of its Predator reconnaissance aircraft, the Predator B, to meet these requirements.

A feature article in the August issue of Defense Tech Briefs (DTB) highlights the development of the Altair/Predator B, including how NASA and GA-ASI met the stringent requirements that the aircraft be able to fly 24 to 48 hours at a primary altitude from 40,000 to 65,000 feet while carrying a payload of at least 660 pounds. Earth science missions will include volcanic observation and other missions that are too difficult, too dangerous, or too lengthy for manned aircraft.
