Anotations

Scope note:

Use only for large communities established in space or on natural extraterrestrial bodies. For smaller manned installations established on natural extraterrestrial bodies for specific functions, use "extraterrestrial bases." Use "space stations" for manned artificial satellites placed in a fixed orbit and serving as a base for specific functions (e.g., scientific observations or the refueling of spaceships).
