Well, we are not exactly using the old model craft to return. We are talking about the Space Shuttle. Which I think can all agree is a far cry from the Apollo craft.
As for the thrust/fuel factor, I took that into consideration. The Apollo craft coasted almost the entire journey. Not much thrust was needed to break away from the earth's orbit as they sling shot their way around and out. And if they did need more fuel for the trip. They can refuel at the ISS, could they not?
