I can only think you are trolling. You think that a floating base in the upper reaches of the Venusian atmosphere is a good first step? No being able to make trips to the surface would limit human involvement to the floating base, so scientific exploration would be very limited. The complexity makes it much more challenging to become self sufficient. How would you propose making a return trip? Or is it a one way mission? As for Jupiter's moons. They are so much further away than Mars, are all much lower in gravity, and much colder temperatures than mars. Our own moon and mars are much better candidates for humans to visit, and attempt permanent bases and perhaps colonies.
