This graphic shows the Pioneer F and G spacecraft (named Pioneer 10 and 11 after launch) flight paths through the Solar System.  The primary purpose of the missions was to travel through the asteroid belt, which both spacecraft accomplished without damage. The secondary mission was to take the first images of the giant planet Jupiter at close range. Pioneer 11 used the gravity of Jupiter to place it on a trajectory to Saturn, where it collected images of the ringed planet.
