The PIs will perform a comprehensive study of the interaction of the jovian magnetosphere with cometary dust from Shoemaker-Levy 9. They plan to explore the spatial evolution of dust particles from (1) the breakup of the comet, (2) the suspected low level cometary activity during the two year trip of the nuclei from breakup until reentry, and (3) the motion of charged dust clouds inside the magnetosphere. Collaborating with a number of other observers, the PIs will analyze the dust detector observation from Ulysses and Galileo. In addition, their models will be used to explain the observed distortion of the dust trails as some of the nuclei reentered the magnetosphere. The ultimate goal of this project is to provide a detailed inventory of the spatial and temporal evolution of cometary dust in Jupiter's magnetosphere.***

探测器将对木星磁层与舒梅克-列维9号彗星尘埃的相互作用进行全面研究。他们计划探索(1)彗星解体时尘埃粒子的空间演化，(2)彗核从解体到重返大气层的两年旅程中疑似低水平的彗星活动，以及(3)磁层内带电尘埃云的运动。pi将与许多其他观测者合作，分析尤利西斯号和伽利略号尘埃探测器的观测结果。此外，他们的模型将用于解释观测到的尘埃轨迹的扭曲，因为一些原子核重新进入磁层。该项目的最终目标是提供木星磁层中彗星尘埃时空演化的详细清单
