These days countries like the USA, China, and (recently) the United Arab Emirates have focused on building colonies on Mars, along with private companies like SpaceX, but researchers have suggested to go to further to Titan, a moon orbiting the planet Saturn. Titan is unique because it has a thick atmosphere and features that Earth has, including rain storms, snow, and bodies of liquids on its surface. However, those liquid bodies on Titan are made of hydrocarbons (Methane, Ethane, etc) instead of water, but water ice is present on the surface and subsurface water is present on this moon as well. But how can we live there and what would we need to stay alive or get around?

Humans could fly on Saturn's largest moon – it's getting there that's the problem
