Challenges and approaches to the robotic detection of enantioenrichment onSaturn's Moon, Titan

Saturn's moon, Titan, is one of the most interesting locations for organic chemistry in the solar system. As a possible follow up to the Cassini-Huyge ns mission, which will conduct the first in situ analysis of the Titan atmo sphere in 2004, studies are underway for missions to explore in detail the chemical composition of Titan's atmosphere, surface, and oceans. In order t o seek out and explore complex chemical systems that may represent steps on the pathway to life, instruments for detection of enantioenrichment should be included on such a mission. The formidable challenges of robotic measur ement of enantioenrichment on Titan are summarized, and experimental approa ches to this problem are reviewed. In addition, some speculations are offer ed concerning locations on Titan where complex fractionation of organic mat erials may have occurred.
