Could Humans Survive on Another Planet? The Biggest Challenges Explained

Imagine waking up and looking out of your window to see a red desert stretching towards the horizon instead of trees, buildings or roads. There is no breathable air outside, no familiar rain and no easy way to call home. This sounds like science fiction, but scientists are seriously studying what it would take for humans to live beyond Earth. Mars is currently the leading candidate for a future human settlement, yet surviving there would be far more complicated than simply landing a spacecraft. From oxygen and water to radiation and food, almost every basic requirement for human life would have to be carefully engineered.
