Exploring Kidd Creek Mine (IMAGE) Brown University Caption Jesse Tarnas, a Brown University graduate and postdoctoral research at NASA's Jet Propulsion Laboratory, work in Canada's Kidd Creek Mine. Water in the depths of the mine that hasn't seen the light of day in a billion years was shown to harbor rock-eating life. New research shows that the subsurface of Mars has the right ingredients to harbor similar forms of life.
