The spacecraft is shown here at the Kennedy Space Centre, Cape Canaveral, Florida, on top of a mockup rocket third stage. Two Pioneer spacecraft were launched towards Jupiter in the early 1970s; Pioneer 10 on 3rd March 1972 and Pioneer 11 on 6th April 1973. The two spacecraft succesfully transmitted many pictures of Jupiter and its moons, providing us with the first close-up pictures of the planet.
