Voyager 1 passes Saturn and Titan, and leaves the plane of the planets
The mission's single most consequential trade. To pass close behind Titan and sound its atmosphere by radio occultation, Voyager 1 had to take a trajectory that deflected it steeply north out of the ecliptic. The atmosphere turned out to be dense and mostly nitrogen, and the cameras saw only unbroken orange haze. The cost was every remaining planet: from that moment Voyager 1 was a spacecraft with no further targets, only a direction.
Historical — it happened, and the record is settled.

NASA Voyager mission science pages — planetary encounter summaries
The encounter dates and principal findings at Jupiter, Saturn, Uranus and Neptune, including the Jovian ring, the resolved ring structure at Saturn, the tilted and offset Uranian magnetic field and the newly found moons at both ice giants. V55 verification basis: THE PAGES WERE NOT REACHED — science.nasa.gov is blocked by this session's egress proxy and the search budget was exhausted. Everything attributed here is standard mission record from general knowledge; a curator must confirm each encounter date and each count of newly discovered moons against NASA's own pages.
