Why Ganymede Would Be a Horrible Place to Live

Ganymede is the largest moon in the Solar System, bigger than the planet Mercury, loaded with water ice, and the only moon known to generate its own magnetic field. On paper, it looks like the perfect place for humans to settle in the outer Solar System. So why would living on Ganymede be so horrible? In this relaxing long-form space documentary, we explore what permanent human life on Jupiter's giant moon would really demand. We look at the brutal cold, the near-vacuum surface, and Jupiter's intense radiation belts, and at why Ganymede's magnetic field cannot keep settlers safe. We also go underground, into habitats buried beneath the ice, to see how water, oxygen, food, nuclear power and closed-loop life support would keep people alive. Then we face the human side: low gravity, medicine far from Earth, hour-long communication delays, and what growing up beneath the ice might feel like. With ESA's Juice spacecraft now on its way to orbit Ganymede, this is the story of a world rich in resources but hostile to life, and of the question of whether humans living there would really be living on the moon, or inside a machine buried within it.
