Well. Now that the Stig has spoken and this is your response, let Darth TT give you a different approach.
Build a shuttle cheat free, that fully encloses a 200t payload consisting of fuel with a docking port either side. Get it to orbit. The shuttle must use a side mounted booster. The shuttle must have a plane shape, no excuses accepted. It can be a custom shuttle, no need to try and copy STS.
When you release the payload, close up the cargo bay and dock to the fuel. Refuel. Now do a flyby tour of the entire Jovian system and return safely to Earth. Nothing is allowed to break. Nothing. The booster is disposable. No extra fuel may be taken on board at any time from anywhere.
