Mars

Mars is known as the Red Planet and it is the last planet from the inner Planets. Earth transits from Mars can be a really interesting thing to watch. Not just because it’s our home Planet. Also because we can often see both the Earth and the Moon. We can also see Cruithne sometimes with Earth and Moon.




The picture shows the transit of Earth that is going to happen on the 10th November 2084. Starting at nine o’clock in England. Sometimes if Mars is not so far away from us we can see it as a glowing red dot at night. On the first of November this year Mars will be right next to us. On the Planet Mars itself, the rocks, the dust (ground) and even the sky are reddish. The skies look orange or it is orange because the wind blows red-orange dust around. The dust was there billions of years ago not when it was formed. After the explosion of thousands of volcanoes. Lava is reddish orange. Mars surface looks like a desert if it was on Earth. Mars is further from the Sun. So it must be also colder. The temperature there is below freezing most of the time. In Mars you can’t breathe. There is no oxygen just carbon dioxide which we can’t breath. The air pressure is only one percent similar to Earth’s. It would bloat your body and turn your blood into gas. The surface of Mars has different looks. Some of the looks look similar to Earth and some like a desert. Mars has a huge canyon called Valles Marineris. It crosses one whole side of the Planet. The canyon is so huge that it could swallow the whole Rocky Mountains. Mars has thin clouds. Not as thick as Venus has, much thinner. As you know Mars also have craters and volcanoes. The Southern Hemisphere is more cratered than the Northern. Scientists, Astronomers and Companies that has got to do with Space have taken photographs and tested the soil. One field of dust dunes, near the Northern polar cap, is bigger than Earth’s Sahara and Arabian deserts put together. Mars has two Moons, one of them orbits Mars in eight hours and the other one in 28 hours. The name Mars was given, after the war: Roman God of War.
Is there a sign that there was life on Mars, once?
Mars is a dry planet with no liquid water, right now. Maybe there was water, but not anymore. There are many dried-up water channels and the red rocks also contained also contained a little bit of water. Scientists believe that, billions of years ago, that nearly all the volcanoes threw out gases and lava from the Planet’s boiling center. Water flowed from under the surface, maybe formed seas. The simplest forms of life, such as algae, may have existed. There was water on Mars for sure in the past. Maybe there is still some frozen water today. What I mean with frozen water is that, our Planet is not the only Planet that had the Ice Age. All the Planets in our Solar-System had Ice Age. The Ice Age on Mars was after the explosion of thousands of volcanoes. Mars is now completely lifeless today. The volcanoes there are now extinct (no longer active). One of them, that is extinct, is called Olympus Mons, is the largest volcano in our Solar-System. It is fifteen miles high.
