Spacers are the group of modified humans descended from the first wave of colonists, which started to leave Earth in 2065. The term Spacer is very general and is primarily used by the people of Earth in a derogatory manner. Spacers prefer to refer to themselves by their planet of origin; that is, Auroran, Solarian, etc.

Each planet has a different culture; in some cases, the cultures are radically different. There are only a few traits that Spacers share in common. First, they have decidedly more advanced technology than available on Earth. Second, they use robots to an incredible extent, due to the low population on their worlds. Third, their lifespans are much longer than those of Earthpeople or Settlers. Fourth, Spacers have exceedingly weak immune systems, since there are no pathogens on their planets.

Some Spacers can be significantly unlike other humans. For example, the Solarians genetically altered themselves to be hermaphroditic.

The first planet outside the solar system that Spacers colonized was New Earth in the Tau Ceti system. When it was not the only Spacer World, it started to be named Aurora and considered the leading world.

Around 2500, the planetoid of Elsevere was already inhabited by an idiosyncratic casted colony of 30,OOO people.

In approximately 3720, Spacers rebelled and started the Three-Week War against Earth. Their cause was to force Earth to make changes in the use of robots, hydroponic agriculture and population control. Defeated Earthers could not trade with the Outer Worlds and even journey beyond the solar system for thousand years.

The last, fiftieth Spacer World, Solaria, was colonized by Nexonians in the early 45th century. It was arranged to prevent overpopulation which happened on Nexon.

Spacers built Spacetown on Earth in 4696, striving to get agoraphobic Earthmen to colonize new worlds.

In 4724, the Auroran Globalist Party had to give in and Earth was finally given the rights to expand into space. Waves of Settlers could set out since then.

In 5030s, the planet Inferno became an example of merging Spacer and Settler cultures, after an ecological and cultural catastrophe.

By the end of the 6th millenium, Spacer Worlds were in decadence and dying out. They were desolate, in ruins, or their populations greatly changed in the folowing millenia.

Relationship with Earth and Settlers[]

Spacers generally view Earthpeople and Settlers with contempt as diseased, short-lived barbarians. Earthpeople and Settlers, in turn, generally regard Spacers as arrogant oppressors, and Settlers also see Spacers as being weak and doomed to decay due to their reliance on robots.

Due to their weak immune systems, Spacers generally wear nose filters and gloves when it becomes necessary to interact with Earthpeople or Settlers, who are in turn required to submit to body sterilization before entering Spacer territory.

This division of humanity lost its base with more or less extinct Spacers and Settlers virtually settled throughout the entire galaxy.


In the time of the Galactic Empire, the epithet "Son of a Spacer" is used in reference to them.

Spacers in the Apple TV+ Foundation series are substantially different with one thing unchanged, they are genetically engineered beings. They are also cybernetically augmented and created by the Galactic Empire just a few centuries before the beginning of story. Their purpose is to operate and navigate faster-than-light starships, called jumships (evidently inspired by the navigators of Dune), because only they can stay awake during jumps.
