This is a good question! Not everyone would be willing to live on Mars because it could be dangerous, but imagine how exciting it would be to live on another planet! You would be playing a major role in history and you would see and learn so much along the way. Throughout history, humans have felt the need to explore and to expand their territory, and this is just another step in that path.

Another reason to send people to Mars is because whenever society is faced with big goals, like making it possible to live on Mars, we see major advances in technology. In order to have people living on Mars, we will need to develop new ways for recycling materials, harnessing solar energy, and many other types of technology.

These advances in technology will also improve our lives on Earth.

Many people want to live on mars for the excitement! It would be an exciting adventure to live on another planet. Another reason would be for research -- to explore another planet and collect new information.

Living on Mars would be a great adventure We've explored almost all of the earth now, and we've walked on the moon, so Mars is the next big unexplored piece of land that we might be able to go to. Some people worry that life on earth would die, and they want people to travel to Mars and even to other solar systems, so there would still be people alive somewhere. I think that's silly, because living on the other planets, and getting to the other planets, is so difficult. I think our best plan is to keep earth as a place where we can live. The sun will start to die in about 5 billion years, but nothing lasts forever.

There isn't a whole lot of reason to live on Mars right now, although in the future that might change for many possible reasons. Mars would be a great place to do science, though, because there are many unanswered questions that we would need to travel to Mars in order to answer.

I am a field geologist, and I spend weeks at a time in mountain ranges studying rocks that hold clues to Earth's history. I would love to live on Mars so that I could do field geology there. A better understanding of the geologic history of Mars would lead to a better understanding of the history of the Solar System and Earth as well.

But if the climate of the Earth changes significantly for the worse (as many scientists fear is ongoing), or if an asteroid or comet impacts Earth, or if a nuclear war or some other cataclysm occurs, the survival of humans may depend on our ability to survive in other locations in the Solar System or beyond. In fact, it is guaranteed that at some point in the future, Earth will no longer be able to support human life. Even though Mars is so inhospitable, it is very important that we begin figuring out how to live there, and elsewhere, beyond Earth.
