Audio data from Huygens has been retrieved as the probe made its descent into Titan. Track One(1) combines several sound samples to portray what a passenger might have heard aboard the craft. Track Two(2) features an audio conversion of radar echoes that may give clues about the nature of Titan's surface. For more, visit ESA's site(3).
