The surface of Mars today is deadly to life as we know it, but it was not always this way. Climate change early in its history changed Mars from a place with habitable environments to a barren desert world. Join us for this presentation by Dr. Steve Ruff that will explore the state of knowledge about water on Mars and the potential for life arising there sometime in the past.
Steve Ruff is a planetary geologist with a focus on the mineralogy of Mars determined via infrared spectroscopy, part of an effort to understand its geologic history and potential for past habitability. Terrestrial field work and lab studies are an integral part of this effort, providing an empirical basis for interpreting data from orbiting spacecraft and rovers. He has been an active member in several Mars missions and a participant in the planning of future missions.
