The journey of La Trobe University’s Dr Courtney Ennis has been complementary to the journey of Cassini. Using the skills and insight learned throughout his journey, he has been able to use the data sent back to Earth by the Cassini space probe to develop experiments that aid our understanding of the chemistry of Titan. From telescopic observations, spacecraft missions, and experiments on Earth, he can piece together a picture of how life came to be on Earth 3.6 billion years ago.
