Diaspora: hard science-fiction role-playing with fate (Fate)
A hard science fiction RPG¸ in a loose setting where groups of star systems are connected by wormholes called Slipstreams¸ which starships can jump between through use of a Slipstream Drive. It uses a variant of the FATE system (Fantastic Adventures in Tabletop Entertainment) from Spirit of the Century¸ including simplified stunts as well as extended star system generation rules. - A description from https://darkshire.net/jhkim/rpg/encyclopedia/ with kind permission of John H.
