Thank, that was I'm trying to doing indeed. But it strange it seems the fuel tanks of mu 2 stations are not filling, one stopped at 1% other is at 0%. I wonder why. They are actually orbiting jupiter, pulled by a couple of tugs. Station can also be "no armor", right? And, do they need refuelling hub in order to fill the tanks?
Yep, is jupiter. A gas giant
Ok, I see what's the problem, they just lost them position, not keeping orbiting
