Which mission's craft became the first to enter interstellar space?

Answer Voyager 1

Voyager 1's main mission was to explore Jupiter and Saturn, which it did, photographing the volcanoes of Jupiter's moons and the rings of Saturn. But not only did the spacecraft photograph the whole solar system, afterward, it entered interstellar space in 2012, becoming the first to cross that threshold.
