  9. Opportunity • Interplanetary hole in one! • Rolled into a small crater called Eagle Crater • Sulfate-rich BEDROCK(!!!) right in front of the rover

  10. Opportunity • Landing site chosen by mineralogy • High concentration of hematite

  11. Opportunity • Embedded in sulfate-rich bedrock – blueberries! • Hematite spherules • Evidence of water

  12. Opportunity • Found meteorites on Mars!

  13. Opportunity • Traveled to Victoria Crater • Many layers of bedrock
