Die Pioneer 11 sondeerder is gelanseer op 6 April 1973 om 02:11:00 [[UTC]] deur NASA vanaf die Amerikaanse Lugmag se Kaap Canaveral-ruimtestasie: lanseerplatform 36A aan boord van 'n Atlas-Centaur vuurpyl met 'n Star 37E aandrywingmodule. Die tweelingsondeerder, Pioneer 10, is reeds 'n jaar vroeër gelanseer op 3 Maart 1972.
