Second Workshop on ‘Titan - Observations, Experiments, Computations, and Modeling’ Miami, Florida, March 24-26, 2008 Saturn’s moon Titan is the only solar system body besides Earth with a thick atmosphere and is widely considered as a natural laboratory on the planetary scale to understand the prebiotic chemistry on proto-Earth. The Cassini-Huygens mission to Titan has opened a new chapter in Solar System exploration and extraterrestrial atmospheric chemistry. On January 14, 2005, the Huygens probe successfully descended through the atmosphere of Titan and safely landed on its surface. An extraordinary new world has been unveiled. The scientific data are currently being archived and analyzed, but the chemistry is far from being understood. This workshop is part of the NSF-Collaborative Research in Chemistry (CRC) Network "Chemistry of Unsaturated Hydrocarbons in Titan's Atmosphere” and the second in a series of annual meetings aimed to better understand the chemistry taking place in the atmosphere and on the surface of Titan. It brings together atmospheric modelers, astronomical observers, mission specialists, planetary scientists, physical chemists (dynamics, kinetics, photochemistry), theoreticia ns (electronic structure, dynamics calculations), astrobiologists, and organic chemists (hydrocarbon and nitrile chemistry). By exploring the current boundar ies of planetary science and chemical knowledge, we can more effectively design new laboratory experiments under well-defined conditions (and recommen d promising directions for further observational searches) and upcoming Solar System missions to resolve hitherto unanswered aspects of molecular synthesis in the Solar System. The workshop features invited (40 min + 10 min discussion) as well as contributed talks (15 min + 5 min discussion) and is limited to 50 participants. Registration forms, meeting site information, and abstracts are available online (http://www.chem.hawaii.edu/Bil301/Titan2008.html) (deadline: December 31, 2007). For additional questions, please email to [log in to unmask] <mailto:[log in to unmask]>. The registration site opens September 1, 2007. We are looking forward to seeing you in Miami.
