> For all intents and purposes the martian atmosphere is no different to the moons Not sure I agree with all intents and purposes. Maybe just some of them? Like say if the intent is to extract CO2 or N2 from the atmosphere, then you'd find more on Mars. Those two things are pretty important for growing things and breathing. Another intent and purpose could be to airo-break the space craft as it flies in for a landing. Though it is probably more annoying than it helps, in the sense that Mars has enough atmosphere that you need to deal with it, but not enough to be helpful in the final descent phase.
