Transcript

  • 1. Mars Exploration Rover: Spirit & Opportunity By Ray Ludwig
  • 2. Overview
    • In this presentation you will learn about:
    • The reasons for the exploration
    • Where the exploration was conducted
    • The science behind it all
  • 3. The Mission
    • Determine whether life ever arose on Mars
    • Describe the climate of Mars
    • Describe the geology of Mars
    • Prepare for human exploration
  • 4. Landing Sites
    • Rovers would be sent to:
    • Gusev Crater, a possible former lake in a giant impact crater
    • Meridiani Planum, where mineral deposits suggest Mars previous had water
  • 5. The Rovers: Spirit
    • Landed on Mars on Jan. 4, 2004
    • Landed in the Gustev Crater
    • Built to last 90 days
    • Has lasted over 1,000 days
    • Picture – Spirit’s launch patch
  • 6. The Rovers: Opportunity
    • Landed on Mars on Jan. 25, 2004
    • Landed in the Meridiani Planum
    • Lasted over 1,000 days
    • Picture – Opportunity’s launch patch
  • 7. Scientific Accomplishments – Spirit
    • Sleepy Hallow- 30ft x 40ft lake-like crater
    • First ever mars photo
    • History's first grinding of a rock on Mars
    • Discovery of Mimi & Humphrey rocks – supposed water effected rocks
  • 8. Scientific Accomplishments – Opportunity
    • Heat shield rock – first ever meteor identified on another planet
    • Opportunity Ledge – Ledge at Eagle crater that seemed to be affected by water
    • To observe soil Opportunity dug the first ever Martian trench
  • 9. Hurdles
    • Occasionally dust covered solar panels which immobilized the rovers
    • Opportunity dug itself into a sand dune
    • Over a 2 day period scientists skillfully dug the rover out
  • 10. The Science
    • Panoramic Camera (Pancam): for determining the mineralogy, texture, and structure of the local terrain.
    • Miniature Thermal Emission Spectrometer (Mini-TES): for identifying promising rocks and soils for closer examination and for determining the processes that formed Martian rocks.
    • Mössbauer Spectrometer (MB): for close-up investigations of the mineralogy of iron-bearing rocks and soils.
  • 11. The Science
    • Alpha Particle X-Ray Spectrometer (APXS): for close-up analysis of the abundances of elements that make up rocks and soils
    • Magnets: for collecting magnetic dust particles.
    • Microscopic Imager (MI): for obtaining close-up, high-resolution images of rocks and soils.
    • Rock Abrasion Tool (RAT): for removing dusty and weathered rock surfaces and exposing fresh material for examination by instruments onboard.
  • 12. The Exploration Now
    • The exploration is on going
    • There is no way of telling how long the rovers will last
    • Scientists collect information everyday that help us to know more about Mars
  • 13. What We Have Learned
    • Although nothing is proven we can be sure that there is a good chance that Mars had a wet past
    • Some say Mars will be inhabitable in the future
    • Has helped us to learn more about space and exploration
  • 14. For More Information
    • The Mars Rover has its own website through NASA (see my web page)
    • Pictures and information are often released to the public for education
