这是人类最具野心的宇宙无人探索计划，目标是土星。这个炫目的美丽星球和它神秘的光环背后，究竟藏有怎样的秘密？那个最大的科学命题－生命的起源，是否将在这里找到解答？我们的镜头将追随这次穿越太阳系的美妙旅行。

    2004年7月1日，卡西尼-惠更斯号太空探测器抵达土星附近，开始了它神秘莫测的土星任务。这项任务是由3个太空署及17个国家组成的空前庞大的专家团队担纲。而这一天，正是这个历经十年准备工作的国际任务的高潮。卡西尼号的幕后团队希望能够通过探索土星及其卫星，尤其是泰坦星，来破解最大的科学命题—生命的起源。

                           
   
                          


   On July 1st, 2004, the Cassini-Huygens spacecraft began its pioneering journey around Saturn. It was the culmination of ten years work, drawing upon the expertise of a team from three different space agencies and 17 different countries. The team behind Cassini also hopes that, by exploring Saturn and its moons, particularly the primordial Titan, they might find answers to some of the greatest mysteries of cosmology, including the biggest of them all: where we all came from.
