NASA's Curiosity Rover is already known for its significant social presence across networks like Twitter and Foursquare, but the Mars rover is scheduled to reach a whole new audience tonight. Curiosity will make a guest appearance at tonight's New Year's celebrations in New York City's Time Square, where millions watch the ball drop each year. According to the rover's official Twitter account, NASA will broadcast a "special message from Mars" on the massive screens to celebrate the end of this year and ring in the next. If you won't be there in person, be sure to tune into live coverage tonight to see what Curiosity has to share.
