Personspace was the term given to how much of the Mutter's Spiral had been explored by humans by the 22nd century. It distinguished between physical space itself and the dimension-puncturing Interstitial Mass Transit System run by the Sol Transit System, considered to have "stopped the planets in their ancient rotation." (PROSE: Transit)
In relation to colony placements along space lanes, the term "human space" was also used. (AUDIO: Three's a Crowd)
