A NASA/JPL travel poster for “The Grand Tour.” The stylized art is reminiscent of mid-century graphic design. There are iconic representations of the four giant planets, with rockets and spaceships jetting across the page from right-to-left.

   Voyager 2 is the only spacecraft to visit all four of the giant planets: Jupiter, Saturn, Uranus, and Neptune.

   NASA originally planned a "Grand Tour" that would use four probes to explore the five (at the time) outer planets.

   That plan was scrapped over cost and replaced with two probes. The idea was to investigate Jupiter and Saturn. If the first probe worked out okay, the second would be directed on to Uranus and Neptune. So Voyager 2 more or less carried out the Grand Tour.
