Lifting Titan's Veil: Exploring the Giant Moon of Saturn [Hardcover]

The authors include a lot of science in this volume, including background information concerning moons and planets across the solar system. Most of this book covers Titan of course, what we know about it and how we came about that knowledge, from early times to the present. Titan's atmosphere and surface and sub-surface conditions recieve the most attention, with the chemistry of the atmosphere discussed at length. Also, the authors debate the possibility of an ethane/methane ocean existing on Titan as the surface temperature, according to available evidence, is close to the triple point of methane. All of this science can of course, as the authors point out, shed light on the formation and evolution of the solar system and in turn give us clues to our own origins in the misty past. As a chemist I especially enjoyed the information on the chemistry of Titan, and the space-buff in me enjoyed all of it. In addition, the Cassini spacecraft is detailed, and there are lots of illustrations, many in color.

On a personal note, I remember being at the space center as a visitor just a few days before the launch of Cassini, in October, 1997, and thinking that here is this spacecraft sitting out there on the pad just a few hundred yards from the Atlantic beach, I wondered then, will Huygens, at the end of it's journey, find another beach? Space travel is cool!

Answering, in the most basic way, the "why" question that often accompanies any discussion of planetary exploration, the authors write, "More than anything else, planetary exploration gives us a sense of perspective, a notion of who we are, where we came from and what our destiny might be. We can learn from all worlds. Each planet and moon in the solar system has its own unique history. Each is an experiment with a different set of conditions..." More specifically, they note that Titan, with its orange-tinted, nitrogen-rich 1.5 bar atmosphere containing traces of hydrocarbons and other organics, might represent an analogue, albeit a cyrogenic one, of the prebiotic atmosphere surrounding early Earth. Considering that mankind has yet to demonstrate time travel, studying Titan may be the only way (outside of modelling and laboratory experiments, both of which have obvious limitations) to explore this critical phase in Earth's history. It goes without saying that studying Titan, especially in situ, is exploration at the cutting edge.

Coming at an especially propitious moment, the book provides a comprehensive synthesis of the body of Titan-related science, which is placed into historical context. Starting with the moon's discovery in 1655 by Christiaan Huygens, the Dutch astronomer, LIFTING TITAN'S VEIL spans a time frame of three and a half centuries of astronomical observations leading up to the modern era of spacecraft reconnaissance and exploration. The book is organized topically, with a distinct narrative style (e.g., the unique "Ralph's Log" feature), and runs the gamut from astronomy to meterology to geology to speculation about future Titan exploration. I highly recommend LIFTING TITAN'S VEIL to all readers. Anyone interested in Titan, this "pale orange dot," will, I think, find something of worth in this work. Indeed, I personally feel that Chapter 3, "Titan's puzzling atmosphere," is alone worth the price of the book.
