On the 14th of January, 2005 the Huygens spacecraft culminated a 7 year 
journey from it's home planet, the Earth, to one of the most mysterious 
worlds in our solar system, Titan.

Saturn's largest moon, Titan is bigger than the planet Mercury and 
perpetually shrouded by a thick orange methane-nitrogen atmosphere.  The 
details of it's surface have never been seen.

We take you now on a journey through Titan's atmosphere, to it's surface as 
seen by the eyes of the Descent Imager and Spectral Radiometer on-board 
the Huygens probe.  (33-0:33)
