Voyager 1 and 2 were designed to take advantage of a rare planetary alignment to study the outer solar system up close. With this chance, Voyager 2 targeted successfully Jupiter, Saturn, Uranus and Neptune.

The U.S. Flyby spacecraft Voyager 1 was launched on September 5, 1977 in destinations of Jupiter, Saturn and Beyond our Solar System.
oyager 1 flew successfully Jupiter and Saturn systems before continuing out into the farthest most reaches of our solar system. Voyager 1 has been observing the interplanetary medium throughout its journey, and is now in interstellar space since August 2012. On November 29, 2017, engineers successfully fired Voyager 1’s thrusters after 37 years of inactivity.
During the Jupiter leg of its journey, Voyager 1 was to explore the giant planet, its magnetosphere and moons in greater detail than the Pioneer spacecraft that preceded it. Voyager 1 was not only to study Jupiter, but to use it as a springboard to Saturn, using the gravity-assist technique.
Voyager 1 succeeded on all counts, with the single exception of experiments using its photopolarimeter, which failed to operate.
Jupiter's atmosphere was found to be more active than during the visits of Pioneer 10 and 11. This fact sparking a rethinking of the earlier atmospheric models which could not explain the new features. The spacecraft imaged the moons Amalthea, Io, Europa, Ganymede, and Callisto, showing details of their terrain for the first time.
One of the most interesting discovery of Voyager 1's was to showing the extreme volcanic activities of Io. It was found that, the heat is generated by its stretching and relaxing occurred every 42 hours. This time is its elliptical orbit that brings it closer to and then farther from the gravity of Jupiter.
This finding revolutionized scientists' concept of the moons of the outer planets. The spacecraft also discovered a thin ring around the planet, making it the second planet known to have a ring, and Thebe and Metis, two new moons.
Voyager 1 was become the second spacecraft to visit Saturn. Its mission there was to explore the planet, its rings, its moons and its magnetic field in greater detail than was possible for its predecessor, Pioneer 11. Voyager 1 met all of its goals except for the experiments planned for its photopolarimeter, which failed to operate.
In place, the spacecraft found Prometheus and Pandora, two moons shepherding the F ring and, another one, Atlas, which shepherds the A ring. Voyager 1 found the Saturn's largest moon Titan with a thick atmosphere which hides its surface from visible-light cameras and telescopes. However, it was founded that, its atmosphere is mostly nitrogen, like Earth, but with a surface pressure 1.6 times higher than ours.
The spacecraft took also images of five others moons: Mimas, Enceladus, Tethys, Dione, and Rhea. The results has revealed the fine structure of Saturn's ring system and, had permit to add the G ring to the list of known rings.
Just as it used Jupiter's gravity to reach Saturn, Voyager 1 done the same thing at Saturn to alter its course and increase its speed that giving it a trajectory to the solar system. The spacecraft entered in interstellar space in August 2012 and became the first to cross into that location.
In interstellar space, Voyager 1 can sample what space is like beyond our solar system. It will remain within the confines of the solar system until it emerges from the Oort cloud in another 14,000 to 28,000 years.
After 40 years, the space travel of Voyager 1 continue
