Will.i.am, one of pop music's most popular artists, is taking his star power to another level.
His new single, "Reach for the Stars," was the first song ever to be broadcast from another planet to Earth. The tune was broadcast from NASA's Curiosity spacecraft, which successfully landed on Mars on Aug. 6. Since the landing, Curiosity has returned photographs and valuable information about the surface of Mars, which is helping scientists determine if the planet can support life.
