Voyager 2 was part of the Voyager program to study the outer planets. Voyager 2 was launched on August 20, 1977, two weeks earlier than Voyager 1.
Voyager 2 was launched by Titan IIIE-Centaur rocket. Voyager 2 is the only spacecraft to have ever made a flyby of the outer planets Uranus and Neptune.
Voyager 2 is currently in the heliosheath area of the Solar System. Heliosheath is the outermost layer of the heliosphere where the solar wind is slowed by the pressure of interstellar gas.
Voyager 1 is currently located in interstellar space.
Voyager 2 has visited Jupiter and Saturn. It flew past Neptune in 1989, but it’s still functioning and communicating with Earth.
Voyager 2 was built at NASA’s Jet Propulsion Lab in Pasadena, California.
Voyager 2 took advantage of a rare alignment of the planets so that it could use a gravity assisting boost as it flew past each one. The increased velocity from Jupiter would help it reach Saturn, Saturn helped it get to Uranus and then to Neptune.
