Airships in a world with 1/3 gravity but 3 times the mass of atmosphere?
In the first question I posted here on Worldbuilding Stack Exchange, I asked if lifting gas would be more effective on a world with 1/3 of Earths gravity but with the same atmospheric composition as here on earth. To my surprise I learned that there would be no difference. I admit I was disappointed; but, the answer did encourage me to do more research.
In my research I learned that a lighter gravity planet like Mars with 1/3 of Earth's gravity would need at least 3 times the mass of atmosphere here on earth to have a surface pressure of 14.7 psi. With that in mind, would airships on a world with 1/3 gravity and the same surface pressure as earth (14.7 psi) but 3 times the mass of atmosphere have higher lifting capacity than here on earth or would it stay the same due to the lower gravitational pull reducing weight and buoyancy?
