NASA Spends $25M On Unmanned Planes, Awards Aviation Prizes

An anonymous reader points out a NetworkWorld story about NASA's purchase of two unmanned aircraft for use in "observing remote locations of Earth not feasible or practical with piloted aircraft." The planes are Northrop Grumman Global Hawks, and NASA selected them for their extreme range and the fact that most other unmanned vehicles don't have the FAA's approval for regular use over the US. NASA also distributed prizes for its General Aviation Challenge this weekend. The goals of the challenge include improving fuel efficiency in aviation, reducing emissions, and aircraft safety. None of the teams were able to achieve the $50,000 prize for managing 30 miles per gallon, but the top team was able to complete the 400-mile course at 28.8 miles per gallon.
