  1. Mars By: Manuel Da Silva, Ashley Moses, Meghan Caffrey, Connor Jones

  2. Basic Properties • Mars Is Terrestrial • Axial tilt of 25.19 degrees • Rotation: Counterclockwise • Length of day: 24 hours 39 minutes and 35 seconds • Length of year: 687 days

  3. Basic Properties Con’t • Distance to sun: 227,900,000 KM • Mass 6.7 x 10^23 KG • Earth Mass: 5.97 x 10^24 KG • Density: 3.9 g/cm3 • Earth Density: 5.5 g/cm3

  4. Weather • Mars experiences seasons like Earth • A summer day in Mars by equator: up to 70 degrees Fahrenheit • During winter at night, temperature can reach minus 195 degrees Fahrenheit

  5. Structure and Composition • Similar to Earth • It has a core and different layers • Core contains mainly Iron and Sulfur • Doesn’t have a magnetic field cause of different core

  6. Atmosphere • Thin and cold atmosphere • Means water can’t exist for long period of time • Atmosphere 100 times thinner than Earth • Mars has no rings

  7. Surface Features • Dry, barren wasteland • Completely rock • Mostly basalt • Covered with a fine layer of iron oxide dust • Also has volcanoes, canyons, wind and water erosion

  8. Volcanoes • Enormous shield volcanoes • Type of volcano built almost entirely of fluent lava flows. • Looks like a shield cause of how low it is to the ground

  9. Olympus Mons • Olympus Mons: largest known volcano in solar system • 2 and ½ times bigger than Mount Everest • 600 KM across base • 25 KM above surrounding plane • No large scale plate tectonics which could be responsible for Martian and Terrestrial volcanoes

  10. Large Canyon Systems • Large canyon systems • Valles Marines: extends for 5000 km, is 500 km wide in the widest areas, and 6 km deep

  11. Running Water Erosion • Running water erosion • Channels as much as 1500 km long and 200 km wide • Suggests that the atmosphere was thicker and more dense in the past

  12. Wind Erosion • Wind erosion • Atmosphere supports high velocity seasonal winds • Winds correlated with solar heating of the surface • Produce dust storms

  13. Moons • Two small moons: Phobos and Deimos • Phobos: only 3000 miles above the Martian surface • Orbits in a little over 7 hours (over 3 orbits daily) • Deimos farther out • Orbits in 30 hours Phobos Deimos

  14. Discovery • Mars is very bright and therefore easily spotted in the night sky • Because of this, we don't know who exactly discovered Mars • Named after the Roman god of war, because its reddish color reminded people of blood.

  15. Space Probe • More probes have visited mars than any other planet. • Vikings 1 and 2 were the first space probes to land on the surface of Mars. • NASA's Mars rover Curiosity has only been exploring the Red Planet since last August • Robot has already had much success • Seven weeks after curiosity landed on mars, scientist announced that the rover had found an ancient streambed • Water once flowed at roughly knee deep levels

  16. Space Probe (cont.) • In February, curiosity used its hammering drill to bore 2.5 inches • First time any rover had drilled into a rock to collect samples from another world • From those samples, Curiosity spotted some of the key chemical ingredients for life • Gray powder, including sulfur, nitrogen, hydrogen, oxygen, phosphorus and carbon.
