Except that on this planet you don't worry about the atmosphere leaking
in. In fact, you don't worry about too many life support issues. Putting
an entire enclosed life-support system on a blimp would be infeasible. I
think you would need something as large as the Hindenburg or bigger. Even
then, the Hindenburg was mostly empty space. By the time you've got all
the equipment you want to take to Jupiter onboard, you are looking at a
LOT of tonnage to support.
