From the reviews:
"Unmasking Europa … brings you face to face with the surface scars of this tiny Jovian moon and tells the story of how our scientific understanding of this enigmatic world has developed. … Through clear descriptions of unfamiliar terms, usefully annotated diagrams, and beautiful colour plates, the story of Europa is made accessible to anyone, even without a prior knowledge of planetary science." (Emily Baldwin, The Observatory, Vol. 129 (1210), June, 2009)
"The icy crust of Jupiter’s moon Europa, cut by dramatic faults and other irregularities, caps a hidden ocean about 100 kilometers deep. Greenberg (planetary sciences, Univ. of Arizona) believes the crust is relatively thin … . his explanations of how tides influenced the Europan crust are generally elegant and interesting. The book includes a few Web sites with images of Europa. Summing Up: Recommended. Lower- and upper-division undergraduates, two-year technical program students, and general readers." (B. M. Simonson, Choice, Vol. 46 (8), April, 2009)
"The book is a very clear and accessible exposition of the Europa observations, and of how movements of the ice crust could have produced them. … the author is gratified that his ‘thin-ice’ model of Europa is now gaining credence, which may well indicate, as he believes, that correct arguments must ultimately win over the scientific community. … this book can be recommended as a good non-technical synopsis of our present understanding of the satellite … ." (Journal of the British Astronomical Association, April, 2009)
"It is written by Richard Greenberg … . His arguments that the thick ice interpretation on Europa is flawed sound convincing … . The new book is stripped of much of the mathematical and geologic terminology used in the original in order to reach a wider audience. … the author is spending more time describing the process of discovery of Europa’s secrets." (Unmanned Spaceflight, October, 2008)
"Centauri Dreams readers already know of my admiration for Richard Greenberg’s … Unmasking Europa: The Search for Life on Jupiter’s Ocean Moon(Copernicus). It’s a lively and challenging book, one which Greenberg used to take sharp issue with many of his colleagues, and … when I reviewed the book, the animated back and forth makes for a fascinating look at how planetary science gets done. … Read Unmasking Europa for a close look at the Europan surface as seen through Voyager and Galileo imagery … ." (Centauri Dreams, October, 2009)
“This book … recounts the fierce friction between the personalities leading the Galileo mission and publishing their interpretations of what they saw. … the story-telling is first-rate and elegantly explains not just the processes at work on this intriguing little world but also the rivalries and political manoeuvring of Big Science. … Unmasking Europa is a gripping story of the exploration of a new world and the often heated debates within science, and is absolutely stuffed with gorgeous images of strange Europan landscapes.” (Lewis Dartnell, Astrobiological Society of Britain, March, 2009)
