  1. Mapping the Surface of Mars NOAO Science Education Group and Chris Martin from Howenstine Magnet High School

  2. Part 1.

  3. Main Features • Craters • Volcanos • Canyons • Rivers • Rock Layers

  4. Part 1. Mapping the Surface of a Planet • http://www.noao.edu/education/astro/remote-sensing/mars/ • Identify geological features • Determine the surface history • How were these features formed? • Which features were formed first and are therefore older? • Which features were formed later and therefore are younger? • 3 Principles to determining the surface history • Superposition (ages of layers) • Cross-Cutting Relationships (e.g., rocks can be cut by rocks) • Horizontal Bedding (rocks deposited by wind or water)

  5. Activity 1 • Using the Mars Orbiter Camera to identify the features • Use the 3 principles to rank from oldest to youngest

  6. Activity 2 • Map of thermal infrared energy emitted from Mars • The “TES” can measure how much energy is being reflected from the surface (albedo). • Learn about unique geology in the Tharsis Province.

  7. Activity 3 • The MOLA image shows the topography or heights, of the region surrounding the three Tharsis Montes volcanoes. • The color scale below the image helps determine the heights of the features.

  8. Part 2. Mapping the Surface of Mars • http://www.noao.edu/education/astro/remote-sensing/mars/ • Take what you know about remote sensing and Mars • Apply it to a set of images of Mars taken so recently that scientists haven’t had a chance to take a close look at all of them! • The activity starts with the Viking Orbiter image of all of Mars. • Most of the images are from the High Resolution Imaging Science Experiment. • More open inquiry

  9. HiRISE Flight Structure(approximately 70 cm in diameter by 1.4 m in length)

  10. Global View First • What kinds of features can you make out in this full image of Mars? • Are they similar to structures you see on Earth? Which ones? • Describe features that you cannot decipher? • Make a comment about what you can say about Mars as a whole planet?

  11. Surface ID Charts
