no
yes a couple
Because the US government has stopped funding to all manned space missions and there has already been enough for the scientists to deal with for a few years.
no, it is too far away.
The Russians did not make any successful moon landings, it was all unmanned.
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.
No, there have not been any manned missions to the outer planets such as Jupiter, Saturn, Uranus, and Neptune. All of the missions to these planets have been conducted by robotic spacecraft. The extreme distances, harsh environment, and long duration of the journey make it currently impractical for human travel to these distant worlds.
No country has sent a spacecraft to Jupiter, but several have launched missions to study the planet, such as NASA's Juno mission which arrived at Jupiter in 2016. These missions provide valuable insights into Jupiter's atmosphere, magnetic field, and moons.
No. Voyager 2 flew past it though.
No, Jupiter has not been visited by humans. The harsh radiation environment, extreme temperatures, and lack of solid surface make it difficult for human spacecraft to survive there. However, unmanned spacecraft like the Galileo and Juno missions have studied Jupiter from orbit.
There were six manned moon landings between the years of 1969 and 1972. During those missions, there were no publicly disclosed reports of alien encounters.
There have not been any manned landings on the "back" side of the moon, for the simple reason that radio communication with Earth would be very difficult.
