06. What would the hotels look like on the outside? What shapes would they be? What materials should we use to build the hotels? (A K2S Question)

From The Space Library

Imagine a giant watermelon with the insides carved out—that would be the shape of one of the modules. It would have to be made out of materials that would be resistant to space particles, asteroids or meteors, and debris that might penetrate the watermelon's skin. The module's skin would also have to protect the guests from radiation, keep the oxygen inside, control temperatures and protect other life-support habitation. The most commonly used materials for building a space module have been metals, such as aluminum and titanium alloys. Only recently have inflatable space modules with multi-layered skin been tested and built to make sure they are strong enough to withstand the harsh conditions of space.
