What starbases are good for?

Starbases (SB) are similar to bases but on orbit.

You can have 1 starbase per base. The cost of your first starbase is 5,000$, to the next one it will increase by 50%, and so one to the 3rd, 4th, etc.

Over the starbases you cannot build these type of structures:

Urban Structures
Gas Plants
Hidro Plants
Metal Refineries
Crystal Mines
Command Centers
Terraform
Multi-level Plataforms
Jump Gate
Biosphere Modification
Tele-Transport Pod
Capital

What starbases can build:

Android Factories
Solar Plants
Fusion Plants
Antimatter Plants
Solar Satellite
Economic Centers
Nanite Factories
Orbital Base
Orbital Shipyards
Research Labs
Robotic Factories
Shipyards
Spaceports
Starbase

What starbases are good for:

Can be built over asteroid belts, bases cannot
Can be built on astros where there is already a base or other starbases
It generates 10~25 debris every full hour
It increases the asteroid belt debris release by 25 per SB level
Good for producing ships near your enemies region or galaxy; restock FTs, HBs
Good for increasing your economy
Good for increasing your scanners capabilities
Good for increasing your research
Good for reinforcing your defenses
