Voyager Mission Title Gif
The Voyager-1 spacecraft was launched on September 5, 1977 and subsequently encountered Jupiter on March 5, 1979 and Saturn on November 12, 1980.

The Voyager-2 spacecraft was launched on August 20, 1977 and subsequently encountered Jupiter on July 9, 1979; Saturn on August 25, 1981; Uranus on January 24, 1986, and Neptune on August 25, 1989.

Both space craft are now traveling out of the Solar System in the "termination shock" phase of their interstellar mission. The trajectory of Voyager-1 is taking it toward the nose of the Sun's heliosphere above the ecliptic while the trajectory of Voyager-2 is taking it toward the nose of the Sun's heliosphere below the ecliptic.

Voyager 1 crossed the termination shock on December 16, 2004, and Voyager 2 crossed on August 30, 2007, on their way to the heliopause and interstellar space.
