Titan is a moon of Saturn, most recently explored by the Cassini/Huygens probes. Titan is of huge interest to scientists, as the conditions in its atmosphere and on its surface bears a striking similarity to those of early Earth.
It is thought that there is a realistic possibility that forms of primitive life could develop - or may already have developed - on the surface or in the oceans of Titan. As a result, there are plans to send further probes to Titan in order to further explore the conditions on its surface and in its oceans.
The theme of the book is how Titan works 'as a planet', with an emphasis on illustrating the features and processes of Titan - where the conditions and materials can be exotic - with familiar analogues from the Earth or other planets. The book will include numerous images from the field, the air and satellites to show comparable features on Earth or other planets. The final chapter, discusses Titan in practical terms as an environment for humans in the future, bringing the place 'to life' (somewhat in a science fiction style, but grounded in fact). Images of geographical and geological features on Earth will be used to illustrate the parallels with Titan.
