Saturn’s Atmosphere
Both of these spacecrafts studied Saturn’s atmosphere. Voyager 1 noted that the atmosphere predominately consisted of hydrogen and helium. These probes also noted the length of the day on this planet, which was almost 11 Earth hours.
Voyager 1’s Course
The sister of Voyager 2 had a course that included drifting past Titan, which is Saturn’s largest natural satellite. This is also the second biggest in the solar system. The first is Ganymede, which orbits around Jupiter.
