ABOUT VOYAGER 2
Voyager 2 is the only spacecraft to have visited Uranus and Neptune, and one of only two to enter interstellar space. Launched 16 days before its twin Voyager 1, it took advantage of a rare planetary alignment occurring once every 176 years to perform the “Grand Tour” of the outer solar system. It crossed the heliopause in November 2018.
