> the escape velocity from Mars requires a massive rocket equivalent to the one we use to leave Earth and therefore more fuel leaving less payload for delivering other resources or supplies

Wait, what? Isn't escape velocity from Mars lower than that from Venus? The surface gravity is far lower on Mars.

I also note that you list "no surrounding breathable atmosphere" as a negative for a rotating space station, but the surrounding atmosphere on Venus isn't exactly breathable either...

i'm not sure how the math works out but you would be launching from a much much higher altitude than ground level on venus, whereas on mars you would be launching from roughly ground level.
