ELI5: Explain Like I'm 5

Space colonization

Space colonization is when people travel to space, living and working there. It's like living on a different planet, because space is not like the Earth. People who colonize space will have to build habitats, or homes, to live in and find ways to produce food, air, and water. To travel between different parts of space, they will need rockets and other special space ships. Once everything is set up, people can explore the many mysteries of outer space.
