Spacer

• Spacers were the fictional first humans to emigrate to space in Isaac Asimov's Foundation and related Robot and Empire series. In these stories, about a millennium thereafter, they severed political ties with Earth, and embraced low population-growth and extreme longevity (with lifespans reaching 400 years) as a means for a high standard of living, in combination with using large numbers of robots as servants.
