ok, hi I have a huge 750 part 150 kerbal ship that i want to get into orbit. I can get it to 72k and nearly get it into orbit but its doesnt quite have enough fuel to create a stable orbit(or any orbit) Short of admitting that a rocket this big just isnt practical or worth the lives of 200+ kerbals and counting, does anyone have any tips on getting it to go a little further. once its in a stable orbit i can dock my refuelling tanker and refuel it so how much fuel it has left isnt an issue. Afraid i havent got an image. Any tips would be appreciated.
