Özet:
Europa – The Ocean Moon tells the story of the Galileo spacecraft probe to Jupiter's moon, Europa. It provides a detailed description of the physical processes, including the dominating tidal forces that operate on Europa, and includes a comprehensive tour of Europa using images taken by Galileo's camera. The book reviews and evaluates the interpretative work carried out to date, providing a philosophical discussion of the scientific process of analyzing results and the pitfalls that accompany it. It also examines the astrobiological constraints on this possible biosphere, and implications for future research, exploration and planetary biological protection. Europa – The Ocean Moon provides a unique understanding of the Galileo images of Europa, discusses the theory of tidal processes that govern its icy ridged and disrupted surface, and examines in detail the physical setting that might sustain extra-terrestrial life in Europa's ocean and icy crust.

Greenberg (Univ. of Arizona) offers a very intriguing book that evaluates the scientific evidence for a thin ice crust on the Jovian moon Europa. Many scientists have recently argued that Europa has a thick crust of ice. Greenberg has theorized that tidal forces between Jupiter and Europa create friction and heat the water, keeping the large global ocean in a mostly liquid state. He describes the science behind his theory, along with the "canonical" political forces he had to overcome to get his theories published and accepted. The project encouraged scientists and engineers to be conservative, so the Galileo satellite made it safely to Jupiter, but some project administrators discouraged creativity and risk taking when analyzing the data. The explanation of Greenberg's theory is clear and concise. Just about any undergraduates, not just geology and astronomy majors, should be able to understand the concepts. Greenberg certainly explains the pitfalls of slow, "self-correcting" science. Science may be self-correcting in the long term, but in the short term, scientific careers can be damaged. Greenberg also explores the possibility of life existing near the water-ice-surface interface. ^BSumming Up: Highly recommended. General readers; lower-division undergraduates through faculty. J. R.
