Name of a program that originated with United Earth and has been continued ever since. The concept was at first uniquely Terran but became a core of Union society. The program aimed and aims to put colonists, occupied installations and outposts on every possible celestial real estate. Basically any rock or object big enough to out a foot on, was supposed to be colonized, utilized and occupied.
The aim of this program was and is to create "consecutive space ". Claiming space as severing region of a space faring society even beyond the boundaries of a star system was a concept that originated long before the Union ever arose, but to truly accomplish it United Earth and later the Union colonized even planet less star systems. Usually with at least one Space station .
This policy is responsible for a very homogenous occupied Union core region . While the Union grew too fast and after 5050 had footholds in many galaxies, the policy remains in effect and every star and star system within 600 light years of Pluribus is occupied and thus makes the densest populated region in known space of the Universe.
