      I think it’s definitely possible. Mars, the Moon and Europa (one of Jupiter’s moons) are the best options, but they’re all far from perfect! We need to be able to cope with the atmosphere (we need oxygen), the different gravity, the extreme temperatures, and we also need food and water. Plus it would take a really long time to even get to Mars. We’d have to think really carefully about how we would take all the things that we need to set up a life for ourselves.

      The Moon has no atmosphere at all, and Mars’ is about 96% poisonous carbon dioxide. Mars’ gravity is only about 1/3 of that on Earth (fun for bouncing around, but bad for normal bodily function!) and the temperature can drop down to a rather chilly -140 degrees! Might need more than a onesie there 😉
