More than a few of you have commented on the Kesslertastic collection of debris in my low kerbal orbit and, furthermore I've had numerous requests for giant stations, moon bases, rovers and other constructs that I've generally barely touched because or time. So, I decided to initiate a 100% reusable space program, we're going to have a reusable launcher that returns to the planet in one piece, we'll build a space station, which will become a hub of interplanetary travel. No longer will missions to distant planets be bold ventures in disposable spacecraft, instead it'll be a case of catching the right series of connecting flights to get you to your destination.
