VOYAGER MISSION

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 with the mission objective of extending NASA's exploration of the solar system beyond the neighborhood of the outer planets to the outer limits of the Sun's sphere of influence and beyond.

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 the heliopause on August 25, 2012 being the first man-made object to enter interstellar space.

Voyager 2 crossed the termination shock August 30, 2007, on its way to the heliopause and interstellar space.
