6. Workshop on Martian Phyllosilicates:Recorders of Aqueous Processes? 1. Although the Red planet was long thought to be habitable as seen from the Earth, the early space missions could not find evidence that Mars ever sustained long lasting bodies of liquid water. 2. Things have changed dramatically with the pioneering discovery of hydrated phyllosilicates in ancient terrains by OMEGA/Mars Express, confirmed and extended by CRISM/MRO. A new era CNES, Paris, October 21-23, 2008

10. Workshop on Martian Phyllosilicates:Recorders of Aqueous Processes? 3. These findings have the potential to open a new window is MarsHistory, for Mars to have harbored habitable conditions. The relevant sites are not located where the mere images would lead to go. 4. Does the findings of phyllosilicates in cratered terrains translate a time correlation or indicate that impacts triggered their formation? 5. Did phyllosilicate formed within perennial water? A new era CNES, Paris, October 21-23, 2008

17. Workshop on Martian Phyllosilicates:Recorders of Aqueous Processes? 6. Beyond the search for extraterrestrial habitable conditions, the MarsPhyllosilicate story constitutes an unique means to enter the first half billion years of planetary evolution, dominated by the heavy bombardment, when plausibly life emerged on the Earth, possibly in similar conditions. What can we learn from the Mars experience? Is the emergence of life a generic process? A new era CNES, Paris, October 21-23, 2008

18. Workshop on Martian Phyllosilicates:Recorders of Aqueous Processes? A new era 7. The Mars missions motto “Follow the water” should become “follow the phyllos” CNES, Paris, October 21-23, 2008

19. Workshop on Martian Phyllosilicates:Recorders of Aqueous Processes? 1. Wrap-up: where and what types of phyllosilicates have been identified at Mars? 2. How these relate to our knowledge from terrestrial studies and experimental results? 3. What does this imply for Martian phyllosilicate formation processes? 4. What record of Mars surface environment? 5. what should we achieve with upcoming missions and lab simulation studies? Objectives CNES, Paris, October 21-23, 2008

20. Workshop on Martian Phyllosilicates:Recorders of Aqueous Processes? We considered that it was the right time for Mars scientists, terrestrial clay experts, extraterrestrial matter (meteoritic) specialists, among many other relevant communities to hear from each other, merge their experience, and envision joined activities both in space and in the lab. What do the Martian phyllosilicates tell us? Objectives CNES, Paris, October 21-23, 2008
