NASA pilots and flight engineers have successfully completed the first science flight of the Global Hawk aircraft over the Pacific Ocean. The Global Hawk is a robotic plane that can fly autonomously to altitudes above 60,000 feet -- roughly twice as high as a commercial airliner -- and as far as 11,000 nautical miles -- half the circumference of Earth. GloPac researchers will directly measure and sample greenhouse gases, ozone-depleting substances, aerosols, and constituents of air quality in the upper troposphere and lower stratosphere.
