Moon shots are awesome, especially when they are moon shots of another world
This is a shot of Titan, Saturn's largest moon. It is the only moon in the solar system
known to have a substantial atmosphere. Or so I have read.

About half the size of our Earth atmospheric pressure at the surface is greater. Would be like the pressure at the bottom of a swimming pool.

it's also the only atmosphere in the solar system that, like Earth's, is dominated by nitrogen. And that's actually a big mystery - both on Earth and on Titan. Why is there so much nitrogen? If you look at Venus and Mars, the amount of nitrogen is very small, only a few percent. On Earth it's 80 percent. On Titan it's 95 percent. original source
