can you mention any flyby missions done here?
Voyager missions,  "Ulysses", etc.
Jupiter
Six years later, the Voyager missions vastly improved the understanding of the Galilean moons and discovered Jupiter's rings.
which of jupiter's moons has water ice surface Europa who discovered it? Galileo Galilei was he the one who named it? The naming scheme was suggested by Simon Marius, who attributed the proposal to Johannes Kepler what is the speciality of it's atmosphere? The surface-bounded atmosphere forms through radiolysis, the dissociation of molecules through radiation. Solar ultraviolet radiation and charged particles from the Jovian magnetospheric environment collide with Europa's icy surface, splitting water into oxygen and hydrogen constituents. has there been any exploration on it? Yes, it began with the Jupiter flybys of "Pioneer 10" and "11" in 1973 and 1974 respectively. any mission scheduled for the future? Conjectures regarding extraterrestrial life have ensured a high profile for Europa and have led to steady lobbying for future missions. how many such moons there of this planet? 79 how big is the planet? Jupiter is much larger than Earth and considerably less dense: its volume is that of about 1,321 Earths, but it is only 318 times as massive

Jupiter [SEP] Flyby missions
Beginning in 1973, several spacecraft have performed planetary flyby maneuvers that brought them within observation range of Jupiter. The Pioneer missions obtained the first close-up images of Jupiter's atmosphere and several of its moons. They discovered that the radiation fields near the planet were much stronger than expected, but both spacecraft managed to survive in that environment. The trajectories of these spacecraft were used to refine the mass estimates of the Jovian system. Radio occultations by the planet resulted in better measurements of Jupiter's diameter and the amount of polar flattening. Six years later, the Voyager missions vastly improved the understanding of the Galilean moons and discovered Jupiter's rings.
