Space structures

Space structures are built by a space factory in places where colonies cannot be built, such as gas giants, asteroids, and warp points.

Military outposts can be destroyed in space combat, the others can be destroyed by bombardment.

	Economy	Research	Planetary Creation
Asteroids	Asteroid mine	Asteroid laboratory†	Artificial planet construction†
Gas giant	Superscalar gas harvester		Gas giant compression†
	Defense	Surveillance	Travel
Warp point	Military outpost Advanced military outpost	Space surveillance system†	Jump gate

† project can be built in systems without a colony.
