The teams, announced by NASA at a Sept. 9 briefing, had the highest scores in the first of four "ground tournaments" that make up the initial phase of the agency's $5 million Cube Quest Challenge. That tournament, held in early August, featured 13 teams who presented their initial spacecraft designs.

"Cube Quest is an opportunity for non-government cubesat developers and builders to compete in lunar orbit and deep space for accomplishments in communications, navigation and longevity," said Jim Cockrell of NASA's Ames Research Center. Cockrell is manager of the competition, part of the agency's Centennial Challenges prize program. [Tiny Satellites Launched from Space Station (Photos)]
