We can (hopefully one day) land on their moons. Jupiter's moons Europa, Ganymede, and Callisto, plus Saturn's moons Titan and Enceladus seem every
bit as interesting (perhaps even more so) than Mars.
By the way, neither Saturn nor Jupiter are "all gas". Both planets are thought to have rocky cores -- cores that are several times larger than the
entire Earth. If you strip away the outer layers of Saturn and Jupiter, you would end up with rocky planets that are even larger than Earth.
However, those rocky cores are so deep and the pressures at that depth would be so great that there would be no way for us to send a probe there --
not with our technology, nor even with any foreseeable technology.
Beautiful picture, OP
