The two companion spacecraft Pioneers 10 and 11 were launched in 1972 and 1973, respectively. They passed through the asteroid belt between Mars and Jupiter without damage, made the first-ever investigations at close range of the great outer planets Jupiter and Saturn and are now on escape trajectories out of the solar system.
