Place a mobile sat repair and salvage old but workible parts, then I'm speculating, repair the Hubble or salvage its array. There was an story about creating zombie satellites a few weeks ago as apposed to launching new ones
Currently the only repairs that I am aware of are possible are thru the KAS mod. But it only reaches to EVA part replacing and using cables to recover floating debris.
Sorry, I must have misread, the original thought would to be have it like the KSC2 but just a larger clusters just to fill an empty kerbin. However, I did not see any thing saying that the space center could be seen from space via its lights.
So I was thinking, if we are to have a space program, would it not be cool to look down on the surface of the planet and see it lit up by kerbal civilization? Not to mention it would be kinda cool to a city highway as a landing strip.
