  1. Water on Mars

  2. Mars is full of cool surface features Lets look at some! (all images credit: Mike Sussman)

  3. The famous “Face on Mars”

  4. Now don’t get all excited…

  5. How Come We Missed These?

  6. Look harder! The Panda! George Washington Screaming!

  7. Kermit the Frog!

  8. Surface Water Flow Features • Geological features suggest that at some point water must have flowed on the surface of Mars • Why? Look like water features on Earth! • Characterized by… • Dendritic vs. Anastomosing Drainage • Fast Formation vs. Slow Formation

  9. Dendritic Patterns River in Yemen Dry Riverbed on Mars

  10. Anastomosing: Branching and then Reconnecting

  11. Islands in Anastomized Streams

  12. Fast vs. Slow Formation • Anastomosing drainage usually the result of a flood event • Dendritic drainage usually caused by erosion over time • So… Which forms more “quickly” • Note that there is some wriggle room in geomorphology… It does what it wants.

  13. What Are We Doing Today? • Characterizing some features on Mars • Figuring out how much water must have flowed to create features using a lil’ guesstimation • Figuring out how old features are (CRATER COUNTING!)
