What would it be like to live on Mars? The movie The Martian has given us some answers. It follows an astronaut named Mark who is left on Mars for nearly two years. In order to live on Mars, Mark finds a way to grow potatoes in a special room. He wears a spacesuit when he is outside his “home”. However, Mark has to face many difficulties, such as dust storms.

In fact, just like in the movie, walking on the surface of Mars without a suit is a bad idea. Your skin would be peeled away like pieces of burning paper; your blood would turn to steam (水蒸气) and you would die within half a minute. There is bad radiation ( 辐射) and dust storms. So people would most likely live in underground homes. If technology improves, more people and construction ( 建筑) materials may be sent to Mars. Only then could people build houses on the surface. And life would start to look like that on Earth. On Mars, people could grow crops, such as wheat and potatoes, in special boxes. They could help make oxygen for humans to breathe like trees do on Earth. But it won’t be an easy thing.

How can people move around Mars? People have suggested cars, bikes, trains, cable cars and planes. However, there are no official plans saying exactly what humans will use.
