Details

Voyager 2

USA 

Active

1977

One of the two craft sent on the first great tour. It flew past Jupiter, Saturn, Neptune and Uranus and is now far out into deep space looking for the heliopause, where the solar wind gives way to the interstellar medium. It entered the boundary of our solar system, known as the ‘heliosheath’ on 30 August 2007  (launched before Voyager 1)
