Which spacecraft made the first flyby of Saturn in 1979? Pioneer 11 made the first Saturn flyby in 1979.

NASA launched Pioneer 11 on 5 April 1973, initially aiming it toward Jupiter. After its Jupiter encounter in December 1974, mission planners used the planet's gravity to redirect the spacecraft toward Saturn. That maneuver made Pioneer 11 the first probe to reach Saturn.

Pioneer 11 passed Saturn on 1 September 1979, traveling through the planet's ring system and collecting measurements of its atmosphere, magnetic field, radiation environment, and rings. It also helped scientists assess hazards for later spacecraft.

A common mix-up is Voyager 1 or Voyager 2, both of which later returned far more detailed images. Cassini was even later: it entered orbit around Saturn in 2004. Pioneer 11 was a flyby spacecraft, not an orbiter.
