1972: Pioneer 10 launched to Jupiter
Pioneer 10, the world's first outer-planetary probe, is launched from the United States on a mission to Jupiter.
In December 1973, after successfully negotiating a distance of 620 million miles and the asteroid belt, Pioneer 10 reached Jupiter and sent back the first close-up images of the spectacular gas giant. A decade later, the spacecraft left the solar system.
Headed in the direction of the Taurus constellation, Pioneer 10 will pass within three light years of another star in the year 34,600. Bolted to the probe's exterior wall is a plaque displaying a drawing of a human man and woman, a star map marked with the location of the sun, and a map showing the flight path of Pioneer 10.
