Mars: What about?

About Mars

    Mars is one of Earth's closest "next-door neighbors" in space. It is the fourth planet away from the sun in alignment and like the rest of the solar system, Mars is 4.6 billion years old. Since the Greeks mythology was copied by the Romans, Mars was named after the Roman's god of war. Both races associated Mars with war because it resembled the color of blood in battle, but when viewed from Earth the planet is a bright reddish-orange color. This color is made possible by the iron rich minerals in the soil, hence why Mar's color is similar to that of rust, which is composed of iron and oxygen.
    No human being has ever set foot on mars but, scientists have observed the planet through microscopes places on Earth and in space. There was one instance when a spacecraft even orbited on Mars and landed on the Red Planet but again not one human has ever set foot on it.  Space probes have carried telescoped to mars and earlier versions of the telescope were designed to observe Mars while they flew past it. With these observations, scientists have found strong evidence that water once flowed on the surface of Mars. Now the water has turned into ice but they still haven't given up hope that it once supported life when the water did flow. Their evidence of this is supported by the material in meteorites that have fallen and been found on earth, but this still does not convince some scientists.
    Mars surface has many unique features, from a canyon system that is much deeper and longer than the Grand Canyon to its mountains that are way higher than Mount Everest, which is earth's highest peak. Mars atmosphere is 100 times denser than earth near the surface, but it is still dense enough to support the type of weather system that has winds and clouds.
    Also, the temperature on Mars is must colder than Earth. It ranges from -195 degrees F(-125 degrees C) to 70 degrees F(20 degrees C) near the equator. Furthermore,  the average temperature on Mars though is about -80 degrees F(-60 degrees C). The reason why Mars is so different from Earth is because it's smaller and it's farther from the Sun. It's average distance from the sun is 141, 620,000 miles(227,920,000 kilometers) which is 1 1/2 times the distance from the Earth to the sun.  The average radius of Mars is 2,107 miles and that's about half the radius of Earth!
