  1. Mars By: Mary Margaret Watkins

  2. About Mars • It was named for the Roman god of war Ares • Mars is 227.9 km from the Sun. • It is about 4.5 billion years old. • It’s diameter is 6,786 km • It rotates once on 24.7 hours, and makes a complete revolution in 687 Earth days.

  3. Atmosphere • The atmosphere is mostly Carbon Dioxide, with some Nitrogen. • The planet looks red from Earth, because of the dust in the atmosphere. • Atmosphere is thin, which causes temperature fluctuations.

  4. Surface • Mountains and craters scar the terrain. • Volcanoes have been erupting periodically over the last hundred million years. • They stopped erupting a few million years ago. • Frequent channels and canyons. • Ice caps on the poles.

  5. How was Mars formed? • From the excess gas surrounding the Sun. • Temperature was high, and the heavier molecules sank to the center. • Mars cooled down quickly. • This meant that hot fluids would have a hard time getting to the surface. • That meant instead of plate tectonics, Mars just had hot spots.

  6. Moons • Mars has two moons. • Phobos and Deimos. • They are small, and not perfect spheres.

  8. Weather • Temperatures range from -207°F, to 80°F • There is wind on mars. • It causes huge dust storms. • The cloud of dust raises temperatures by about 30°Celsius. • Dust storms are similar to hurricanes on Earth

  9. Life on Mars • There is currently no life on Mars. • It was most likely wet about 3.7 billion years ago. • It is the one planet most like Earth. • There is a possibility that there was once some sort of life on Mars. • Microscopic life has been found in a meteorite.

  10. Missions to Mars • There have been 15 missions involving Mars. • Missions took pictures or sent Rovers. • All of our knowledge of Mars comes from these missions. • More famous ones are the Viking 1-2, Mariner missions, and Pathfinder.

  11. Face on Mars • Twenty-five years ago, NASA’s Viking 1 spotted the likeness of a human face. • It was an enormous head, two miles from end to end. • It was a huge rock formation, with human features formed from shadows.

  12. Mars….a home? • Most realistic location for life, aside from Earth. • It’s temperatures aren’t too harsh, and it has ice caps, which means some water. • The problem is…..NO OXYGEN!!!!

  13. Extraterrestrial Life!! • Many believe that there is, or has been life on Mars • Life has never been proven, but there have been many claims to sightings • UFOs, Aliens, Sci-Fi novels, Area 51, crop circles.
