Launch Pioneer 10 ( 02 March 1972 )
Pioneer 10 entered the Asteroidbelt in July 1972 and emerged in February 1973 ... passing safely as we know ... during 7 months ... Jupiter Flyby in November 1973. So we had Jovian flyby 7 months after passing Asteroid belt! Launch Pioneer 11 ( 05 April 1973 ) Pioneer 11 entered the Asteroidbelt in March 1974 and emerged in ??? ( September 1974 ) ... encountered Jupiter in December 1974. Already 3 months after it cleared the Asteroid belt ? ( went on for flyby of Saturn in August 1979 ) Does someone have exact dates for both Pioneers' milestones ? Best regards, Philip |

Flight time to the Asteroid belt varies for both Pioneers depending on the position of the Earth during the launch, March 1972 and April 1973 respectively.
Upon arrival I suppose that ' passage-time ' should be about the same for both vehicles as the Asteroidbelt is always presented as a doughnut shaped ringtube... I guess this example illustrates that ' different data ' is listed on several webpages of the Worldwide Web ... we at Unmanned Spaceflight should at least get the data right |
