It seems to me that like any system, the go to Mars plan will benefit from modularity. That’s what the Gateway might offer - multiple paths to Mars are possible

- ncmncm 6y agoA "lunar gateway" is much worse than useless for getting to Mars. A side trip from low Earth orbit to the gateway takes nearly the same delta-V as to Mars. But unless you are willing to take weeks getting to the gateway, you use up most of a Mars transfer delta-V to stop there, and as much delta-V again to get to your transfer orbit to Mars. In other words, LEO-to-gateway-to-Mars takes almost 3x the delta-V of going directly from LEO to Mars.
