Montage of planets and some moons that the two Voyager spacecraft have visited and studied. It is the only program that visited all four outer planets. A total of nine spacecraft have been launched on missions that involve visits to the outer planets; all nine missions involve encounters with Jupiter, with four spacecraft also visiting Saturn.
Neptune has been directly explored by one space probe, Voyager 2, in 1989. As of 2024, there are no confirmed future missions to visit the Neptunian system, although a tentative Chinese mission has been planned for launch in 2024. [1] NASA, ESA, and independent academic groups have proposed future scientific missions to visit Neptune. Some ...

The primary mission of Voyager 1 was to explore Jupiter, Saturn, and Saturn's largest moon, Titan. Voyager 2 was also to explore Jupiter and Saturn, but on a trajectory that would have the option of continuing on to Uranus and Neptune, or being redirected to Titan as a backup for Voyager 1 .
In January 1986, Voyager 2 became the first spacecraft to visit Uranus. During its flyby, it discovered 10 new moons, 2 new rings, and a magnetic field tilted at 55 degrees off-axis and off-center. In August 1989, Voyager performed its last flyby, going by Neptune and visiting its moon Triton.
Artist's depiction of Pioneer 10, the first spacecraft to visit Jupiter. The exploration of Jupiter has been conducted via close observations by automated spacecraft.It began with the arrival of Pioneer 10 into the Jovian system in 1973, and, as of 2024, has continued with eight further spacecraft missions in the vicinity of Jupiter and two more en route.

The two Voyager space probes were originally conceived as part of the Planetary Grand Tour planned during the late 1960s and early 70s that aimed to explore Jupiter, Saturn, Saturn's moon, Titan, Uranus, Neptune, and Pluto.
