2. Terrestrial Planets to scale

4. Characterize the Geology Determine if Life Ever Arose on Mars Characterize the Climate Prepare for Human Exploration WATERWATER When? Where? Form? Amount? Common Thread LIFE CLIMATE GEOLOGY HUMAN MARS SCIENCE STRATEGY: Follow the Water! Or Salts!

5. Mars and Earth both formed 4.5 billion years ago. Did Mars once have a warm, wet environment for life?

13. Impact Craters-- Simple Craters Crater on northern Elysium Planitia. Meteor crater in Arizona

14. Impact Craters – Mars & Earth Yuty Crater, Mars is located at 22 degrees North and 34 degrees West.

15. Dunes in Proctor Crater and Saudi Arabia These dune and ripple features are found inside Proctor crater, Al Hibak

16. Yardangs Aorounga impact crater, wind eroded grooves southeast of the Tibesti Plateau, Chad. Yardang field, Argyre Planitia

17. Wind Streaks Wind vortices generate bright wind streaks downwind of most impact craters on the SW slopes of Pavonis Mons Bright streaks of salt and clay dust are strung out downwind of dry lake beds in Patagonia.

46. Lava Layering –Making and Mapping Volcanoes Making and Mapping Volcanoes Destination Mars! http://ares.jsc.nasa.gov/Education/activities/destmars/destmars.htm Students are introduced to lava layering as they construct a volcano. Then they investigate an “unknown” volcano to record its history. (NOTE: In workshops this is often divided into two activities using the first part to introduce planetary processes and the second part when studying plane surface exploration.)
