This is what you said: > If you can't get there without a stop at Mars, then you really, really can't get there with a stop at Mars. Stopping at Mars costs extra. This is as asinine as saying, if you can't get somewhere without a stop at the gas station, then you really, really can't get there with a stop at the gas station. Stopping at the gas station costs extra. After all, it costs fuel to take an exit on the freeway and go to the gas station. It costs fuel to leave and go back on the freeway. It costs extra! Energetically, any trip where you have to make a detour to a gas station, costs more than a trip where you don't make a stop there.
