DARPA is holding a competition to find ten large weather balloons. Winner gets $40,000!

To mark the 40th anniversary of the Internet, DARPA has announced the DARPA Network Challenge, a competition that will explore the role the Internet and social networking plays in the timely communication, wide area team-building and urgent mobilization required to solve broad scope, time-critical problems. The challenge is to be the first to submit the locations of ten moored, 8 foot, red weather balloons located at ten fixed locations in the continental United States. Balloons will be in readily accessible locations and visible from nearby roadways.

The first person to identify the location of all the balloons will win a $40,000 cash prize.  The balloons will be positioned on December 5, 2009.
