Silicate Mineralogy on Mars Indicates Wet Past

Using data from the CRISM instrument on NASA's Mars Reconnaissance Orbiter, astrobiologists from NAI's SETI Institute and Marine Biological Laboratory teams present findings of silicate mineralogy indicating a wide range of past aqueous activity in the Mawrth Vallis on Mars. This work, published in the August 8 issue of Science, suggests that abundant water was once present on Mars and that hydrothermal activity may have occurred. The Mawrith Vallis could be a landing site for future rover missions to Mars.
