In London, people made a model of a Martian house at the Royal Observatory of Greenwich. People designed the house to be situated in Valles Marineris, which is a system of canyons that runs along the equator of Mars.

The Martian atmosphere is about 100% humid on most nights, so the house will pull out the water from it. The house will provide oxygen for people as well. People on Mars will have 3D printers, which can make almost everything that they would need, from tools to plates and toothbrushes.

This all may sound like science fiction, but a million people could be living on Mars by the mid-2060s, according to Elon Musk.
