Abstract: Planetary climates, and in particular the hydrological cycles that form an integral part of it, are central to questions of habitability. The long-term history of these cycles, the state and distribution of water, and the exchange of volatiles with the surface, are often obscured by the dynamic nature of the atmosphere. Fortunately, other lines of evidence (chemical, geological, isotopic) form a record of a planet’s climate history and past potential habitability. In this talk I will focus mainly on Mars and questions about its “modern” frozen climate over the last billion years. I will discuss ongoing puzzles regarding the potential for liquid water, and morphologic signatures that offer clues for a range of open questions
