Which one? The Pioneer program launched between 1958 and 1978
Pioneer X was launched in 1972. It passed Jupiter at the end of 1973. After that it didn't pass near any more planets, so it's hard to give an exact answer to this question.
Jupiter has been visited by 8 spacecraft. These were Pioneer 10, Pioneer 11, Voyager 1 and 2, Galileo, Ulysses, Cassini and New Horizons. The very first mission to explore Jupiter was Pioneer 10, an American spacecraft launched in 1972. This was a true pioneering mission in that, before it left Earth, no one knew whether spacecraft could travel through the asteroid belt between here and Jupiter and survive the trip.
There were many Pioneer missions. Please see link for more information
In August 1977 Voyager 2 was launched and in September 1977 Voyager 1 was launched. Although launched 16 days after Voyager 2, Voyager 1 reached Jupiter first and began sending photos back to Earth in January 1979.
Pioneer 11 was launched on April 6, 1973. It began studying and photographing Jupiter on November 3, 1974. Its closest approach to Jupiter was on December 2, 1974, and it left the vicinity on January 1, 1975, having used a gravity assist from Jupiter to alter its trajectory and kick it on its way toward Saturn.
Pioneer 10 was launched 3rd March 1972
Pioneer 11 was launched 5th April 1973 at 02:11:00 UTC

Pioneer 10 was launched in 1972 to explore the solar system. It arrived at Jupiter in December of 1973. The final signal received from Pioneer 10 was in 2003 when it was many millions of miles away from Jupiter.
Pioneer 10 was launched almost 41 years ago, in 1972. It was never designed to return to Earth, and no living creatures were aboard. Communication with it was lost in 2003.
The first US space probe was named "Pioneer 1". It was launched on 11th October 1958.

The two spacecraft that have apparently escaped the Sun's gravity force and have now passed into outer space are the inter-stellar space probes Pioneer 10, launched in 1972 and Voyager 1 launched in 1977.
The Pioneer company set up the first automobile shop in Australia in 1898. The Model-T Ford was launched in Australia in 1915.
Pioneer 10 was launched on March 2, 1972 to study Jupiter, some of its large moons and interstellar space. The spacecraft is believed to still be operational, but communication was lost in 2003. Both Pioneer 10 and 11 have a gold anodised plaque attached that should give alien lifeforms some information about the human race should they find it.
