Your about to see a slide show of “Mars” By: Lindsey and Haley! MARS! The Red Planet By Lindsey Provencher and Haley Rainier! Main Differences between Mars and Earth! • Mar’s solar day is 39 minutes and 35.244 seconds longer than Earth’s day! • One earth year is 365 days and one mars year is 687 days! Mars’ Atmosphere! • Made up mostly of Carbon dioxide (95%) • Nitrogen 3% argon 1.6% • Liquid water can’t exist because the Atmosphere is too thin. • Only a little bit of water can exist on the thin clouds, but there is signs of ancient floods Materials Mars is made of! • Outer surface-basalt that was brought to the surface by ancient volcanoes • The volcanoes put iron oxide dust with a fine powder consistency on the surface • That dust gives the planet its red color • The core is mostly iron and 17% sulfur • The core is surrounded by the mantle which is made of silicates Mars compared to the Earth and Sun! • Mars is 230 million km from the sun • Mars is 35 million miles from the Earth • Mars and Earth are both terrestrial planets, which means they have the same makeup (core, mantle, crust) Mars’ color! • Red • The iron oxide on the surface makes it red • The iron oxide creates a very powdery red dust Name of Mars! • Mars is also known as the red planet • Mars, the name came from the Roman’s god of war. • The blood-like color is related to the Roman’s god of war • The Egyptians named mars “ Her Desher” meaning the “red one” Mars’ moons! • • • • • • • Two moons- Phobos and Deimos Deimos is the smaller moon ( 15x12x11) km Orbits around Mars every 30 hours Small, lumpy, and heavily cratered Phobos is the larger moon (27x22x18) km Orbits around mars 3 times a day Phobos is on a collision course with mars Travel time: Earth to Mars! • Approximately 214 Earth days or a little over 7 months • It would take less time if we had technology to carry enough fuel to travel directly to Mars • You would have to slow down once you take off, so you could enter Martian orbit • You could get to Mars faster with a nuclear-powered rocket Mars’ Surface! • Mars’ surface is similar to Earth’s moon • Has a reddish color which comes from the iron oxide in the soil • The surface also holds Magnesium, Chloride, Potassium, and Sodium • The soil could grow organisms such as asparagus Mars’ Geographic features! • Mars has Olympus Mon- highest mountain in the solar system • Mars has Valles Marineris- the largest canyon • Mars has polar ice caps • Mars has canyons and volcanoes Exploration of Mars! • 1964 to 1970, Mariner was sent, it was the first successful space craft • We have sent space crafts to reach Mars and explore it • Sent exploration rovers- Mars Rover in 2003 Discovery of Mars! • There is not a known person who discovered Mars • Astronomers such as Aristotle saw Mars and classified it as a star • The Astronomers could see Mars because it is so bright • 1659- Christian Huygens discovered features of Mars • He thought there was life on Mars, but it was actually water canals. Temperature on Mars! • Extremely cold temperature • Average surface temperature is -63 degrees Celsius can fall as low as 140 degrees Celsius and as high as 20 degrees Celsius • The temperature on Mars is colder than Earth temperature, because Mars is farther from the sun and Mars has a thinner atmosphere so it can’t hold heat Mars time! • A Mars day is only 39 minutes and 35 seconds longer than Earth’s day • One Earth year = 365 Earth days • One Mars year = 687 Earth days Mars’ Seasons! • Mars’ seasons are very similar to Earth’s • Mars’ seasons are twice as long because Mars has significantly longer years • Seasons are similar because Mars has an axial tilt of 25.19 degrees which is close to Earth’s tilt Rotation! • It takes Mars 687 Earth days to rotate around the sun. • It takes Mars 669 Martian days to rotate around the sun. • Martian days are also called Sols The Fun facts of Mars!! ;D • Mars’ mass is 6.42x10 to the 23rd power kilograms • Mars’ volume is 163,115,609,799 cubic kilometers • Mars is 230,000,000 kilometers from the sun • Mars’ diameter is 6787 kilometers • Mars has no rings Human life on Mars! • Mars does not support human life, but it may have billions of years ago • Evidence of human life has been found • Evidence included: traces of water, and the proper setting for life • The only living things that could possibly survive on Mars now are micro-organisms in the soil and dust Interesting Facts! • A day in Mars is equal to 24.6 Earth hours • If you weigh 100 lbs. on Earth, your weight on Mars would be 38 lbs. (multiply your actual weight by 0.38) • The orbital speed of Mars is 24.2 Kilometers per second • Mars is the God of War in Roman mythology (Ares) Works Cited! • http://airandspace.si.edu/mars/explore.html • http://www.universetoday.com/14841/howlong-does-it-take-to-get-to-mars/ • http://solarsystem.nasa.gov/planets/profile.cf m?Object=Mars • http://planetfacts.org/what-is-mars-made-of/ Thank you for watching “MARS” • • • • By Lindsey Provencher! :D AND Haley Rainier! :D
