The Ames Research Center Pioneer 11 plasma analyzer experiment provided measurements of the solar wind interaction with Saturn and the character of the plasma environment within Saturn's magnetosphere. It is shown that Saturn has a detached bow shock wave and magnetopause quite similar to those at Earth and Jupiter. The scale size of the interaction region for Saturn is roughly one-third that at Jupiter, but Saturn's magnetosphere is equally responsive to changes in the solar wind dynamic pressure. Saturn's outer magnetosphere is inflated, as evidenced by the observation of large fluxes of corotating plasma. It is postulated that Saturn's magnetosphere may undergo a large expansion when the solar wind pressure is greatly diminished by the presence of Jupiter's extended magnetospheric tail when the two planets are approximately aligned along the same solar radial vector.
艾姆斯研究中心的先驱者 11 号等离子体分析仪实验提供了太阳风与土星相互作用的测量结果，以及土星磁层内等离子体环境的特征。结果表明，土星有一个与地球和木星非常相似的分离弓形激波和磁层顶。土星相互作用区域的尺度大小大致为木星的三分之一，但土星的磁层对太阳风动压的变化同样敏感。土星的外磁层被膨胀，这可以通过观测到大量的共转等离子体通量来证明。据推测，当两颗行星大致沿相同的太阳径向矢量对齐时，木星延伸的磁尾使太阳风压力大大降低，土星的磁层可能会发生大扩张。
