Colonising Mars might seem like it's a long way off, but there are scientists that are working on the idea right now, determined to make it a reality. Journalist Stephen Petranek explains the science behind it and what life will be like in his book How We’ll Live on Mars.
Why would humans want to move to Mars you may ask? well Petranek argues that the move would be an “essential back-up plan for humanity.” In colonising other planets the human race stands a better chance of survival long term, but to do so is going to mean living a life that is quite literally alien to most of us.
