I’m excited for Dragonfly, because on the list of places in the solar system that I desperately want more pictures from, ‘Titan’s surface’ is right up there at the top with ‘Jupiter’s atmosphere.’

Places where helicopters can work is places with sufficient atmosphere, which is why the list is what it is
Ah, but what if you brought a large balloon, inflated it, and flew a helicopter inside the balloon?
Jupiter is already on the list…
Blowing my mind that Gas Giants are just big ole balloons
It’s an inside out balloon! Gravity holds the atmosphere in, not a cloth sheet
i see, gravity is made out of cotton
So you are saying that with some cloth or plastic, you can break the record for biggest balloon?
What Dyson sphere builders don’t want you to know! It’s all in pursuits of claiming the hot air balloon hall of fame!
And I have a hard time believing that there isn’t some solid or liquid (or maybe some other exotic state of matter, due to the heat and pressure) inner core way down in there, even if it’s relatively tiny compared to the size of the planet.
Even if it was entirely made of gas when it formed, surely some materials would have fallen in over the eons that could stay solid/liquid at the pressure/temperature of a gas giant’s core?
Yes, other elements/compounds have fallen into Jupiter over the aeons but even if it was just hydrogen, it is big enough that the pressure alone causes a transition between gas and liquid and farther down solid. There just isn’t a set border where you can say that it is one phase on the one side and a different phase on the other. It does more of a slow transition where the gas gets thicker and thicker until at some point you can say it’s definitely a liquid instead of a gas, which then gets thicker and thicker until it’s not moving anymore.
Similar for Saturn.
There is a core, it’s just comparatively tiny and does not have a clear boundary
Filling the balloon woth helium should keep it from hitting the ground and popping
