Voyager 2 is the only spacecraft to have visited all four giant planets (Jupiter, Saturn, Uranus, Neptune) and crossed the heliosphere into interstellar space. Voyager 1 crossed the solar system boundary but didn't visit Uranus or Neptune. The Viking probes were Mars landers/orbiters that didn't leave the inner solar system.
