MARS GROUP 1. Nguyen Manh Thin 2. Tran Van Luc 3. Nguyen Ba Huy HA NOI, 26-04-2010 Mars Introduction  Mars is the fourth planet from the Sun in the Solar System and also the first planet in orbit lies outside the orbit of Earth.  The solar system including Nine planets, including the Mars, revolve around the sun. The mars  The planet is named after the Roman god of war, Mars. It is also referred to as the "Red Planet" because of its reddish appearance, which is caused by iron oxide that is prevalent on its surface.  The Mars takes 1.9 years to make a complete revolution about the sun. Its average distance form the Sun is 142,000,000 miles.  The mars is almost spherical in form, with an average diameter of 4,270 miles. The average density of the mars is 2,97 g/cm3. Atmosphere  The atmosphere of mars is quite different form that of the earth. It is composed primary of carbon dioxide with small amounts of other gases. The six most common components of the atmosphere are: Carbon Dioxide (CO2): 95.32% Nitrogen (N2): 2.7% Argon (Ar): 1.6% Oxygen (O2): 0.13% Water (H2O): 0.03% Neon (Ne): 0.00025 %  The atmosphere of Mars can become quite dusty. This is because small dust particles can still be suspended in the air.  The atmosphere of Mars is much thinner than the Earth. Temperature and pressure  Surface pressure averaging 1/100th that at the surface of the Earth.  The average recorded temperature on Mars is -63° C with a maximum temperature of 20° C and a minimum of -145° C. Surface  The uniquely red global surface of Mars is marked by many interesting features - some like those on the Earth and others strangely different. The reddish color is caused by rust (iron oxide) in the soil.  Some of these features are; volcanoes, canyon systems, river beds and dune fields. This is an image of the surface of Mars.

But the poles have lots of ice made from water The water ice might give us clues about life on Mars We don't know if Mars has life now, or if it ever did in the past Discover Mars  Mars is much like Venus it's very bright and therefore easily spotted in the night sky Because of this, we don't know who exactly discovered Mars We do know it was named after the Roman god of war, because its reddish color... strange feature on the surface of the Red Planet It was later called the Syrtis Major  In 1877, astronomer Giovanni Schiaparelli discovered what he believed to be several lines crossing one another He claimed they were water canals made by intelligent creatures  In 1971, Mariner 9 visited Mars and sent back images of enormous volcanoes and vast canyons It discovered Olympus Mons, now the most famous... moons and named them Phobos, which means fear, and Deimos, which means panic They were named after the mythical horses that drew the chariot of the Roman god, Mars  Mars is still a big question for humanity and scientists in particular The end♥•´¯) ๑۩۞۩๑♥ Thank you !!! ♥๑۩۞۩๑ (¯`•♥ . also the first planet in orbit lies outside the orbit of Earth.  The solar system including Nine planets, including the Mars, revolve around the sun.
