Jack Mustard of Brown University discusses emerging concepts of habitability on Mars at the 2012 Canadian Space Summit.
Abstract: Analysis of the most recent spacecraft data have led to discoveries that are expanding the scope of what might constitute habitability on Mars. Curiosity will no doubt rewrite our understanding of sedimentary processes on Mars, but what about the vast subsurface? What is role of impact cratering? And how should we factor in the exciting recurrent slope linea? Analyses of critical analog environments is similarly opening new avenues of inquiry. How do these recent discoveries shape our view of Habitability on Mars?
