Personally, i hate the idea of "landing" on Jupiter. The idea is awful since Jupiter's so-called-surface-thingy is mainly composed of gases. And you know the stuff i suggested if you read my posts in the awfully big "discussion-spam-oneidea thread". So why don't you make Jupiter's moons hidden in the GUI, until you've flown to Jupiter's orbit (using Hohmann transfer orbit/and Tier 3 or 4 rocket . After that, you could access its moons. Also, you could create medium space station to it's orbit. Read my post in the thread of dinammar. Anyone support the idea that only large celestial bodies can support space stations? i know this is unrealistic, but too many space stations create lag. Jupiter would be ideal to make a larger space station than on overworld, And it would be Medium Space Station Core, MSSC, while on Overworld, the standard base starter would be Small Space Station Core SSSC. And on other solar system, Space station orbiting some planet twice the size of Jupiter, or, orbiting the star of the system, would be LSSC. You maybe could create floating "HooliganLabs" Station, which would collect the hydrogen and then could be used as fuel"Kethane". If you read this micdoodle8, please rate and please make this happen.
