为了理解地球上生命的起源(S)，寻找和研究地外环境是至关重要的，在那里，参与我们星球上生命出现的一些过程仍然在发生。这是天体生物学的目标之一。在这一框架下，研究地外有机质是必不可少的，对于益生菌分子进化当然不是有限的兴趣。土卫六是土星最大的卫星，也是唯一一个大气层与地球大气层相似的行星体，是这些天体生物学问题的主要兴趣之一。它与原始地球有许多相似之处，是一个行星规模的类似于益生菌的实验室，目前正在进行复杂的有机化学研究。
For understanding the origin(s) of life on Earth it is essential to search for and study extraterrestrial environments where some of the processes which participated in the emergence of Life on our planet are still occurring. This is one of the goals of astrobiology. In that frame, the study of extraterrestrial organic matter is essential and is certainly not of limited interest regarding prebiotic molecular evolution. Titan, the largest satellite of Saturn and the only planetary body with an atmosphere similar to that of the Earth is one of the places of prime interest for these astrobiological questions. It presents many analogies with the primitive Earth, and is a prebiotic-like laboratory at the planetary scale, where a complex organic chemistry in is currently going on.
