New York: Springer. – 2007. – 306 p. This book has arisen from a unique workshop, entitled Geology and Habitability of Terrestrial Planets, held at the International Space Science Institute (ISSI) in Bern, Switzerland, on 5–9 September 2005. The goal of this workshop, as articulated by the conveners, was to deﬁne the inﬂuence of planetary geologic evolution on habitability and to assess the conditions necessary for life, using the Earth, Mars, and Venus as examples. The intent was to focus on the relationship between a planet’s origin and evolution and its capacity to sustain habitable environments. Chapter 1 introduces habitability from a fundamental, biological perspective. This chapter delves into the questions of what requirements are necessary for life to exist and how geology creates those environments. Chapter focuses on the earliest stages of Earth history and the development of habitable conditions. Chapter 3 then covers a broad scope of topics, describing how the geologic evolution of a planet, both on the surface and in the near subsurface, creates habitable environments that evolve along with the geology. Chapter narrows in on the importance to habitability of volatiles in the atmosphere, on the planet’s surface (e.g., liquid water), and in rocks. Chapter 5 reviews the exchanges among a planet’s interior dynamics, the atmosphere, and the magnetosphere and the ways in which these exchanges modify habitability. Chapter 6 explores these topics in a different light by addressing the stability of planetary atmospheres and their protection by the magnetosphere.
