Relation Types

The vocabulary of edges this atlas draws between its own entities and to entities in other atlases: operated-by linking a mission, spacecraft or observatory to the agency that runs it, crewed-by linking a mission to the astronauts who flew it, orbits linking one celestial object to another, discovered-by reserved for celestial-object attribution and often crossing into Science, and the general associated-with tie. This category exists so the vocabulary itself has a documented, browsable home rather than living only in code.
