For the people arguing that there is a Rover being sent to jupiter you are wrong There is a probe being sent to the moon Europa to make an attempt to prove there is a subsurface ocean. Basically what this probe is going to do is send smaller probes down to Europas surface in order to get her samples of the ice on its surface. Plus those probes are going to have cameras so we can also see what they are grabbing. Jupiter has no surface. This has already been proven through numerous amounts of radiation telescopes that can pierce through the thick layer of clouds. Even Jupiter's core isn't completely solid, it's a bunch of spinning iron shrapnel that spins at its center. This iron is what pri.arily causes the large gravitational pull.
