Moving to Mars

Some people believe that humans could live on Mars by the year 2100. Our own planet, Earth, is becoming more and more crowded and polluted because of the rapid increase in population. It is hoped that people could start all over again and build a better world on Mars. Here is what life there could be like.

At present, our spacecraft are too slow to carry large numbers of passengers to Mars—it would take months. With the development of technology, by the year 2100, the journey might only take about 20 minutes in spacecraft that travel at the speed of light! However, the spacecraft would travel so fast that the journey to Mars might be quite uncomfortable. Many people would feel ill.

Humans cannot survive without water, oxygen or food. So far, nobody knows whether there would be enough water or oxygen on Mars for people there. Moreover, scientists are not sure whether plants could grow on Mars. Food would most probably be in the form of pills and would not be so tasty.

Gravity could be another problem. The gravity on Mars is only about three‑eighths of that on Earth. People would have to wear boots that are specially designed to prevent themselves from floating off into space.

Compared with life on Earth, life on Mars would be better in some ways. People would have more space. They might live in houses with huge comfortable rooms. Also, robots would do most of their work so that they could have more time to relax.

There would probably be no schools on Mars. Every student would have a computer at home connected to an interplanetary network. They would study at online schools with “e‑teachers”.

Life on Mars would be interesting as well as challenging.
