Project Voyager, originally called "Mariner Jupiter/Saturn 1977," was approved by NASA and the U.S. Congress in June 1972. It was a dual spacecraft long-range mission that conducted a "Grand Tour" of the Outer Planets, visiting Jupiter, Saturn, Uranus, Neptune, as well as various planetary satellites, and continued beyond to the outer reaches of the Solar System. The project was managed by the Jet Propulsion Laboratory (JPL).

The name of the project was changed from "Mariner Jupiter/Saturn" to "Voyager" in early March 1977. A March 16, 1977 memo from Project Manager John Casani officially notified personnel that the project was to be known only as Voyager.
