NASA is holding a $30,000 contest to boost the power of the solar arrays on the International Space Station. The object of the contest is to maximize power output and minimize shadowing of longerons, the long arms holding the arrays to the station, which are sensitive to temperature changes. The work of the ISS Longeron Shadowing Optimization Challenge would allow astronauts to perform more experiments, increasing the station's scientific returns. The contest is open to all TopCoder members, which itself is free to join. (Image Credit: NASA)
