- investigate the circulation, dynamics, structure, and composition of the planet's atmosphere;
- characterize the morphology, geology, and physical state of the satellites of the planet;
- provide improved values for the mass, size, and shape of the planet, its satellites, and any rings;
- determine the magnetic field structure and characterize the composition and distribution of energetic trapped particles and plasma therein.
The 3-axis spin stabilized Voyager spacecraft were 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.
