Returning Americans to the Moon, done correctly: make SpaceX and ULA work together. Falcon Heavy to launch to LEO the Orion spacecraft and ACES which has been retrofitted with a landing system and one refueling tanker by F9. ACES will then perform a TLI burn and start its journey to the moon. Once there it can get easily down into low lunar orbit (much higher dv than that European Service Module) where the RL10s will make a deorbit burn. ACES lander is designed to land belly down and has 32 H2/O2 (powered by waste gases not hypergols) RCS thrusters to handle any pitch, yaw and roll requirements. The crew compartment is at the front and there is an escape system which can be performed if the deorbit burn or descent phase goes wrong.
