The role of hydrothermal activity on Mars in altering crustal materials and sequestering volatiles is a critical component in understanding the interactions between the atmosphere, surface, and hydrosphere of Mars. In turn, these interactions are key elements in understanding the martian climate history, surface geology, and potential for past life on Mars. Identification of hydrothermal deposits at the surface of Mars, especially within a region in which the geologic context is clear (e.g. a volcanic region such as a Apollinarius Patera), would provide valuable information about the geologic history of the planet, and would be indicative of a potential site for the search for evidence of life on Mars. Specific hydrothermal mineral assemblages will be dependent on the environmental conditions under which the country rock was altered. Mini-TES, however, has the capacity to identify a wide range of alteration products, and Mossbauer Spectrometer will be able to identify both altered and unaltered iron-bearing bearing minerals, and will yield information on the environment in which iron oxidation has occurred. The instruments on the 2003 rover will have the capability to identify hydrothermal deposits present at the surface of the landing site, potentially yielding information about the nature of the environment in which hydrothermal alteration occurred.
