Mars is also the fourth planet from the sun, is known as the red planet and is the seventh largest. Mars is named after the Greek goddess Mars the god of war. It was taken from a long distance because while this picture was taken while there was a dust storm. Mars is known for its harsh dust storm. Thats why scientists say that life on Mars is and will be impossible. The reason scientist believe Mars is impossible to live on is because of its tempature. PAGE 2 MISSIONS Mars rover "SPIRIT" The name of the first spacecraft to visit Mars is Mariner 4 in 1965. Mariner 4 sister to Mariner 3 reached Mars in 1965. It did not land but it orbited Mars taking exactly 22 pictures. Those pictures were then sent to the scientists at NASA. The spacecraft found a cratered and the atmosphere was thiner than expected.

A lot of other spacecrafts have followed. Like Mars 2 the first spacecraft to land on Mars and the two landing Vikings in 1976. After 20 years Mars Pathfinder sucessfully landed on Mars on july 4 1997.

After 20 years Mars Pathfinder sucessfully landed on Mars on 1997 july 4th. In 2004 the Mars expidition rover "Spirit" and "Opportunity" landed on Mars sending back geologic data and lots of pictures. They are still doing that for over than a year on Mars.Mars Clobal Survivor, Mars Odyssey, and Mars Express. are Mars orbiters and they are still operating. This picture is the 1st picture of viking 2 landing pictures. The picture is of Viking 2 landing spot. There lots more pictures of Mars from Viking 2 PAGE 3 LIFE ON MARS This picture was taken by Mars rover. NASA believes that this picture is proof of life on Mars. Scientist say life on Earth originated from Mars. But Mars has so harsh dust storm. Most people dont believe that there can be life on Mars because of the dust storms. Mars dust storm will kill anyone or anything if it gets caught in one. But this picture somewhat proves that life on Mars is true. PAGE 4 TEMPERTURE The temperture on Mars is as harsh as the dust storms. The tempertures are as cold like 30 C at the subsolar aphelion and perihelion. This picture is the reaction to the harsh weather. The tempature causes a major affect to Mars climate. Even though Mars average tempature is -67 F it can go up to -207 F. At Mars winter pole it goes as hot as 80 F.



PAGE 5 COMPARE Earth and Mars have similar seasons beacause the tilt of its rotation axis. Mars sun is about the same as Earths. Just like Earth Mars seasons are affected by the distance from the sun. PAGE 6 CONTRAST Mars atmosphere is only 1% of Earths. Also Mars has no ocean so that means it has no where to store heat from the sun. Mars has a larger annual variation in solar input. Mars atmosphere responds quickly to surfing changes and atmospheric heating. Mars atmosphere tempurture can be visible over Martian years. Because of this large storms are generated. And a year on Mars will be 686 days. Also Mars gravity is 38% of Earth. And Mars sunlight is only 44% of Earth. PAGE 7 GEOGRAPHY Mars radios is a little over half of Earths. We now know that it boasts scenery on a scale that makes Mount Everest and the Grand Canyon seem unimpressive by comparison.
