Titan at H+3 months Jonathan Lunine, Professor of Planetary Science and of Physics Chair, Program in Theoretical Astrophysics, University of Arizona

In mid-January the Huygens probe descended through the clouds and haze of Titan's atmosphere to reveal a surface cut by channels, soaked in methane and with a consistency described as that of a famous French dessert.  I will summarize what we knew about Titan before Cassini and Huygens, the major questions about Saturn's largest moon that the joint NASA-ESA mission was designed to answer, and where we stand today with respect to answering these questions.
