Suggestion: astronauts or whatever you wanna call them....they can put things such as struts,fuel tanks,solar panels when on control and when EVA.
They only can put things if there are already a fueltank.or place to put into..they cant put things on space...
Really great if you build a rocket in space!..
You start from a fuel tank in spacce then you have a gigantic space station!!
