There are many travelers, smaller factions and fringe groups within the Settled Systems, but some go mad and become Spacers.
Who are the Violent Spacers?
Spacers are humans that have gone out into the Settled Systems and become violent. Much like bandits, these travellers care nothing for the wellbeing of others, and will frequently raid outposts and other facilities for supplies. There is no reasoning with a Spacer, and many consider Spacers to have gone mad, or crumpled under the pressures of living in space.
The Spacers faction provides a number of unique Starfield faction quests with unique rewards and objectives.

How to join the Spacers
It is not possible to join the Spacers, as they are a random collection of individuals, rather than a cohesive faction. “Spacers” is just a general term for any Spacefarer that wanders the Settled Systems and engages in banditry. You could well already be considered a Spacer by several NPCs without your knowledge.
