Was there any missions to Ganymede?

There have been no missions to Ganymede. All the information we have gathered from Ganymede and the other moons of Jupiter have been from the Pioneer 10, Pioneer 11, Voyager 1, Voyager 2, Ulysses, Cassini, and New Horizon's spacecraft which did flyby-by of, or orbited, Jupiter. Any other information had been gathered from spectroscopic analysis from telescopes on Earth.
