Next flight is scheduled for Titan, which is a lot easier. The gravity is lower, but there's a lot more atmosphere, which means our helicopter can be nuclear powered!
Is that even possible? I mean… with how volatile and exotic the atmosphere is, wouldn’t what a craft would be doing be more akin to how a submarine travels under water? Would “flying” even be the correct term? Wouldn’t it be more like navigating violent torrents of differently-dense gaseous layers? Some of which are (sometimes) liquid?
Atmospheric pressure changes based on altitude, so there's probably some point where Jupiter's atmosphere that's a similar pressure and temperature to earth.
I looked it up, and the region of Jupiter's atmosphere at 1 bar is -100C. So you theoretically you could fly a modified Earth plane, it would just be a bit chilly.
Interestingly, though, Venus does have a zone with Earth-like temperature and pressure.
What makes cold temperatures a problem on earth is ice forming frombwater wapour in the atmosphere. No idea what you're likely to get on titan, but probably not that.
