Voyager 1 Flyby Geometry
                                             Voyager 2 Flyby Geometry





























    Each of the 3-axis spin stabilized Voyager spacecraft was equipped with an enabling scan platform, a challenging limited computer and eight-track digital tape recorder. The mission was designed to take advantage of a planetary alignment that occurs every 175 years. Although Voyager’s goal was to explore Jupiter and Saturn and their environments, different options were reserved for the 2 crafts. Voyager 1 was targeted to Jupiter, Saturn and Titan while the Voyager 2 trajectory allowed it to continue on to Uranus and Neptune.

    The Voyager 1 encounter spanned the time period between 1980-08-22 and 1980-12-14 with closest approach on November 12, 1980 at a distance of 184,300 km from the planet center. While the Voyager 2 encounter spanned 1980-12-14 to 1981-09-03 with closest approach on August 25,1981 at a distance of 161,000 km from the planet center

    Voyager's objective was the exploration of Jupiter and Saturn, and their magnetospheres and satellites. Major emphasis was placed on studying the satellites in as much detail as possible. The study of Titan, the only satellite in the solar system known to have an extensive atmosphere, was nearly as high a priority as studies of Saturn itself
