Reviews
"Carr discusses estimates of Mars's original endowment of volatiles, the mechanisms of degassing, mechanisms of their loss to space or incorporation into the soil. . . .Carr is critical of some pet hypotheses but objective in his evaluations. . . . Very surprisingly, a plausible andwell-documented case is made by Carr for survival during space transport and possible natural contamination of Earth by Mars life as the result of giant impacts on Mars. Did you know that Archea have been cultured from the interior of a salt crystal 200 million years old? I suredidn't."--Science, "Water on Mars is a comprehensive book and it very favorably presents theproblem expressed by the title."--Pure Applied Geophysics, "The book summarises the issues and problems concerning the reconciliationof the observational data with evolutionary models." --Geo Abstracts, "Carr discusses estimates of Mars's original endowment of volatiles, the mechanisms of degassing, mechanisms of their loss to space or incorporation into the soil. . . .Carr is critical of some pet hypotheses but objective in his evaluations. . . .
