On Voyager 1’s heels (relatively speaking), is its twin, Voyager 2, which not only flew by Jupiter and Saturn but continued to Uranus and Neptune, the only spacecraft to do so. Now it is leaving the solar system. Voyager 2 is currently traveling through the “Heliosheath,” the final region where solar wind slows, and will eventually join Voyager 1 in interstellar space. It, too, contains a “golden record.”
