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 ![]() |

You're right Toma, some drawings use the Torus ringshape to illustrate the Asteroidbelt, which is of course very empty... How could that many spacecraft otherwise pass it safely ?

Some of the Mars flyby missions went further from the Sun than the orbit of Mars, so presumably they'd be 'first' (depending on how one defines the asteroid belt!).
