“Our science emphasis can be stated broadly as defining the global habitability of planets, with a current focus on Mars and past and present conditions that may have been suitable for the development and evolution of life.  The unraveling of geological processes and defining geochemical cycles of possible biological relevance form the core of the research.  Remote sensing from orbital, landed, and rover-based platforms, together with development and use of quantitative approaches for modeling the data and processes are our primary tools.”
