Just as there is Cyberpunk,  Steampunk, Postcyberpunk,  Deiselpunk, Atompunk, Retropunk, Biopunk, Clockpunk, Sailpunk, and Nanopunk, so there is Spacepunk.

The characteristics of “punk” is a person, or group of people, or a bunch of misfits or outsiders or rebels, fighting corruption of the government, or simply getting by, in a  cynical,  dystopian, crapsack, or even grimdark universe.  Morality is grey vs black or even grey vs grey, with no good guys but conversely no real villains.
