    Spacecraft and Mission Description
    Pioneer 10 was launched toward Jupiter in 1972. This spacecraft was the first one to fly to Jupiter, Saturn, and beyond. After Pioneer 10 emerged through the asteroid belt, Pioneer 11 was launched on a similar trajectory on April 5, 1973. Both launches used an Atlas/Centaur/TE364-4 launch vehicle.

    Mission Objectives or Goals
    To explore the interstellar medium beyond Mars
    To investigate the asteroid belt and assess hazards for outer planet Missions

    To provide in-situ measurements of the Jovian radiation environment and magnetosphere.
    To provide in-situ measurements of the distant heliosphere.

    Note: The Pioneer Missions were carried out before effective processes for archiving were in place. As a result documentation of the mission is incomplete and some data is missing. A NASA special report, designed for the general public may fill in some of the missing information.
