  1. We cannot predict orbits with this kind of precision. We wouldn't know whether it's on a collision path a few decades before a potential impact. A small change in its course we would be able to achieve would leave us just as uncertain.

  5. Not feasible regardless of heating method.

    My back-of-the-$100-bill calculations show that in typical upper Saturnian atmosphere conditions you can get at most 80 g / m^3 of lifting power even if you heat the gas 150 K delta T. So in order to lift just Cassini's RTG (57 kg; you probably need it all in order to communicate back to Earth) you would need something like a 800 m^3 envelope, that would by itself weight something like 20 kg at least. So in order to lift something useful you would need to increase the volume. Such relatively large balloon will probably be ripped apart by winds (1500 km/h and more) pretty soon.

    Disclaimer: me no rocket scientist.

  6. The density of the atmosphere goes up as you go down. So does the density of whatever gas you fill your balloon with, because it is under the same pressure as the surrounding atmosphere, or slightly larger. Which brings us to the next question.

    What do you propose to fill your balloon with? The atmosphere outside is mostly hydrogen (96.3%) with a bit of helium. Your typical helium-filled weather balloon would sink right through, and your not-so-typical hydrogen-filled balloon would only float without any payload.

    The only thing that can float in hydrogen and carry some heavier-than-hydrogen payload is hotter hydrogen.

    So they would need to build what's basically a hot air balloon. They could have it heated by burning some oxygen I suppose. I have no desire of calculating a plausible total mass to payload mass ratio for such a contraption, I guess it would be too large to be useful.

    Meh. They should have a cheat code on the note itself. Punch it in and it doubles in value, or something,

  8. Yes.
