Voyager 2 lifted off from Space Launch Complex 41, or SLC-41, at Cape Canaveral, Florida.
The launch took place on August 20, 1977, aboard a Titan IIIE/Centaur rocket. Although Voyager 2 launched first, its name reflects the intended order of planetary encounters: Voyager 1 followed on September 5 and traveled on a faster trajectory, reaching Jupiter and Saturn before its twin.
SLC-41 was one of the major Titan launch facilities at Cape Canaveral. The Centaur upper stage provided the final boost needed to send Voyager 2 onto its interplanetary path, while the launch vehicle’s earlier stages supplied the initial thrust through the atmosphere and lower ascent.
The launch complex is sometimes confused with facilities used by other Titan missions or later Atlas V flights. Voyager 2 did not launch from SLC-40, SLC-37, or SLC-17. Its trajectory was deliberately longer and more circular than Voyager 1’s, allowing it to continue onward to Uranus and Neptune.
