This story behind the brilliant success of the Cassini-Huygens space mission to Saturn's largest moon, Titan, details a monumental achievement that took 15 years to accomplish. Sponsored jointly by NASA and the European and Italian Space Agencies (ESA and ISA), the Huygens probe was sent to explore Titan's atmosphere, which is similar to that of primitive earth around four billion years ago, in search of new data that may unlock the secrets to how life began on Earth. The probe's touchdown on the surface of Titan in January 2005 marked the farthest a man-made spacecraft has successfully landed from Earth. As well as being a fantastic scientific story, this chronicle captures the dynamics that enabled this group of highly diverse people to fight against great odds and obstacles to triumph together.
