50 Space Colony Writing Prompts for Mars, Moons, and Beyond

Space colony writing prompts are most interesting after the first flag-planting moment. Once people live somewhere permanently, they need schools, plumbing, maintenance schedules, laws, celebrations, jobs, emergency plans, relationships, and reasons to stay.

These prompts focus on colonies as communities rather than generic survival outposts.
