What is mars

Mars is the fourth planet from the sun and the next planet beyond Earth. It is, on average, more than 142 million miles (‪228.5 million Km) from the sun. The size of Mars is about one-sixth the size of Earth. Mars is known as the Red Planet. It gets its red color from the iron oxide (like rust) in its soil.

Mars is named for the ancient Roman god of war. The hindues called the planet mangal ( मंगल ) or karttikeya the god of war. And The Greeks called the planet Ares the god of war

Mars is very cold. The average temperature on Mars is -80 degrees Fahrenheit and in winter, near the poles temperatures can get down to -195 degrees F (minus 125 degrees C). 

Its surface of mars is rocky, with canyons, volcanoes, dry lake beds and craters all over it. Red dust covers most of its surface. Mars has clouds and wind just like Earth. Sometimes the wind blows the red dust into a dust storm. Tiny dust storms can look like tornados and large ones can be seen from Earth. Mars’ large storms sometimes cover the whole planet. mars have Mounties and also have plane surface but the whole planet is look like endless desert 

Mars has about one-third the gravity of Earth. A rock dropped on Mars would fall more slowly than a rock falls on Earth. A person who weighs 45 kg on Earth would only weigh about 16.7 kg on Mars because of the reduced gravity.

Mars's atmosphere is much thinner thn Earth’s. The atmosphere of Mars contains more than 95% carbon dioxide and much less than 1 percent oxygen.

so the life on mars can not possible with out spacesuit and a close shelter. Human need's a fully air tight cabin with good amount of oxygen, water is liquid form. the shelter should be able protect them by mars' large storms and other natural activities happens on mars.
