NASA is calling for coders to help develop algorithms to detect, track, identify and mitigate the effects of asteroids. The government agency explains what they need in a weirdly cheery video, in which a voice-over reminds us of that pesky asteroid that came out of nowhere and exploded over Russia last year and says coders should care about asteroid hunting because the dinosaurs would have cared if they knew about this problem. NASA joins Planetary Resources Inc. to run the Asteroid Grand Challenge Series, which is set to start on March 17 and last through August. Each competition is designed to help NASA scientists analyze the massive amounts of data gathered by asteroid missions.
