Mission Objective. The mission objective of the Voyager Interstellar Mission (VIM) is to extend the NASA exploration of the solar system beyond the neighborhood of the outer planets to the outer limits of the Sun's sphere of influence, and possibly beyond.
Voyager 1. NASAâs Voyager 1 was the next mission to arrive at Saturn, passing the planet on November 12, 1980. It flew within 124,000 km of Saturn and sent back a torrent of pictures. It was also able to make a flyby of Saturnâs moon Titan, and returned stunning images of Saturn and its rings. After passing Saturn, Voyager 1 sped off into interstellar space, where itâs still going now, and still sending back data.
