How many spacecraft have been to Saturn?

Four spacecraft have flown by Saturn so far. In 1979, Pioneer 11 became the first spacecraft to fly by and study Saturn up close. Voyager 1 flew by in 1980 and Voyager 2 in 1981. These spacecraft studied many of the moons of Saturn as well. In July 2004, the Cassini spacecraft reached Saturn. It continues to send back observations of the planet, its moons, and ring system. All of these missions made many important discoveries and sent back wonderful close-up images of Saturn, its moons, and ring system.
