Lets talk about Planet Mars

  1. 1. MARS (4TH Terrestrial Planet)
  2. 2. Astronomical Symbol of Mars
  3. 3. Hubble Telescope Picture of Mars This NASA Hubble Space Telescope view provides the most detailed complete global coverage of the red planet Mars ever seen from Earth.This picture was taken on February 25, 1995, when Mars was at a distance of 65 million miles.
  4. 4. MARS EARTH Distance from Sun 141.6 Million Miles 93 Million Miles Radius 6378 km 3397 km Diameter 4222 Miles 7926 Miles Length of Year 687 Earth Days 365.25 Days Length of Day 24 hours 37 minutes 23 hours 56 minutes Gravity 3.72 m/s2 9.8 m/s2 Temperature Average -81 degrees F Average 57 degrees F Number of Moons 2 1
  5. 5. Size comparison of Earth and Mars.
  6. 6. • Mars is the fourth planet from the Sun. ELEMENTS CO2 95% N 3% A r 2% H2O trace – clouds, ice caps
  7. 7. • the second smallest planet in the Solar System • Named after the Roman god of war- Ares • often described as the "Red Planet" because the iron oxide
  8. 8. Soil
  9. 9. hydrology Polar Caps North polar early summer ice cap South polar Midsummer ice cap
  10. 10. Volcano Olympus Mons (Mount Olympus )
  11. 11. Gigantic Canyon Valles Marineris, or Mariner Valley,
  12. 12. Atmosphere on Mars  Mars has a rocky, dry terrain with huge volcanoes and deep valleys.
  13. 13. The tenuous atmosphere of Mars, visible on the horizon in this low-orbit photo.
  14. 14. Phobos About 14 miles in diameter Orbit close to the planet Named after the character Phobos (panic/fear) Rises in the west, sets in the east, and rises again in just 11 hours
  15. 15.  About 8 miles in diameter  Named after the character Deimos (terror/dread)  Rises as expected in the east but very slowly  30 hour orbit of Deimos, 2.7 days elapse between its rise and set for an equatorial observer as it slowly falls behind the rotation of Mars
  16. 16. Mariner missions In July of 1965, Mariner 4, transmitted 22 close-up pictures of Mars. All that was revealed was a surface containing many craters and naturally occurring channels but no evidence of artificial canals or flowing water.
  17. 17. The First Rover Mars Pathfinder
  18. 18. Spirit Opportunity
  19. 19. In March 2005, Spirit studied rocks in the “Paso Robles” area that have a high sulfur content. Much of the high sulfur is contained in a hydrated iron-sulfate mineral that can only have formed in the presence of liquid water. Spirit
  20. 20. Opportunity Opportunity’s spectrometer and microscopic imager found that rocks near the lower slopes of Endurance Crater were affected by water both before and after the crater formed.
  21. 21. Curiosity
