Mars - A Warmer, Wetter Planet (Springer Praxis Books / Space Exploration)
From the reviews:"Kargel does an excellent job of tying together the work of many scientists and whose results provide evidence for the hypothesis that Mars may have periodically had a warmer, wetter climate than previously recognized. Kargel, as astrogeologist with the U.S. Geological Survey in Flagstaff, Arizona, integrates and explains such diverse work as geomorphological observations, theoretical calculations, and measurements of mineralogy and chemistry from orbiting spacecraft. The book is full of excellent examples of the most recent imaging data from NASA missions to Mars, as well as many photos of terrestrial analogues, which surely will aid the nonspecialist in understanding how planetary geologists go about understanding the landforms of Mars…"Specialists and enthusiasts  will find that the inclusion of detailed information drawn from a wide range of subdisciplines makes for a well-rounded story... "Kargel's entertaining book presents one evolving path of scientific thought regarding Mars that is gaining wider acceptance. It will instigate useful, stimulating debate on the role of water in shaping the Mars we see today and point how we might enhance our understanding of the Red Planet in the future." Science (11 March 2005) "… [Mars: A Warmer, Wetter Planetis] a welcome read for someone looking for more contemporary details about the red planet than just captions to pretty pictures. Kargel marshals an impressive array of information to argue that Mars was once a warm and wet planet, with rivers and seas covering its surface. … Recent discoveries from the Mars Exploration Rovers and Mars Express only serve to bolster Kargel’s conclusion."
