In August 1989, Voyager performed its last flyby, going by Neptune and visiting its moon Triton. The gravity assist carried Voyager 2 below the ecliptic plane. In March 1979, Voyager 1 made its close approach to Jupiter, capturing detailed images of the planet and its moons, with Voyager 2 conducting its flyby four months later.
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.
Voyager 2 returned images of Jupiter, as well as its moons Amalthea, Io, Callisto, Ganymede, and Europa. [3] During a 10-hour "volcano watch", it confirmed Voyager 1 ' s observations of active volcanism on the moon Io, and revealed how the moon's surface had changed in the four months since the previous visit.

Flybys of Jupiter’s moon Io, the only known volcanic world in our solar system, have captured images of a massive lava lake and a towering Matterhorn-like mountain.
Adrastea (/ æ d r ə ˈ s t iː ə /), also known as Jupiter XV, is the second by distance, and the smallest of the four inner moons of Jupiter.It was discovered in photographs taken by Voyager 2 in 1979, making it the first natural satellite to be discovered from images taken by an interplanetary spacecraft, rather than through a telescope.

The high-resolution photos from Voyager 2, taken closer to Jupiter, left scientists puzzled as the features in these photos were almost entirely lacking in topographic relief. This led many to suggest that these cracks might be similar to ice floes on Earth, and that Europa might have a liquid water interior. [30]
The Voyager 1 and Voyager 2 probes visited Jupiter in 1979, discovering the volcanic activity on Io and the presence of water ice on the surface of Europa. Ulysses further studied Jupiter's magnetosphere in 1992 and then again in 2000. The Galileo spacecraft was the first to enter orbit around Jupiter, arriving in 1995 and studying it until 2003.
