The sun emits a stream of particles called the solar wind. The solar system presents a wide variety of obstacles to the solar wind in the form of planetary magnetospheres. Magnetospheres arise from the internal magnetic field of a planet and serve to deflect the solar wind from the surface of the planet. Mass from the solar wind hits the magnetosphere and is diffused toward the poles and then carried out behind the planet in a structure called the magnetotail. Io is a moon of Jupiter that also provides particles to its magnetosphere from within, and so it can be used to trace the flow of particles from within the magnetosphere. This project will use observations of sulfur and sodium ions to trace out the diffusion of particles from within Jupiter's magnetosphere to better understand the process of diffusion in magnetospheres. The project will use a dedicated telescope for their observations. The project will also create a children’s book, “The Misfit Telescope” with a companion website and social media stream that use the benefits of diversity in scientific instrumentation as a parable to illustrate the benefits of racial and cultural inclusivity.The proposed project will study the Io Plasma Torus (IPT) around Jupiter in order to gain insight into the Jovian magnetic field. The project will use the Io Input/Output observatory to make time domain observations of S II and Na lines in the IPT to determine the nature of diffusion of material. IoIO is a small-aperture robotic coronagraph that operates nightly, contemporaneously recording narrow-band images of the IPT ins S II. Combined with a model of the IPT, the observations will show whether diffusion is driven by mass loading from Io or by activity in the middle Jovian magnetic field. The project's children's book will show the value of both being in the minority and havingg a different point of view and of being in the majority and accepting and respecting the minority point of view. The book will be produced by the Planetary Science Institute's award winning public outreach team.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

太阳散发出称为太阳风的颗粒流。太阳系以行星磁层的形式呈现了太阳风的各种障碍。磁层是由行星的内部磁场产生的，并从行星表面击败太阳风。太阳风的质量撞击了磁层，并朝着杆子扩散，然后用称为磁尾的结构在行星后面进行。 IO是木星的月亮，也从内部提供颗粒，从而可以用来从磁层内痕迹颗粒的流动。该项目将使用硫和钠离子的观察结果来探索木星磁层内颗粒的扩散，以更好地了解磁层中的扩散过程。该项目还将与伴侣网站和社交媒体流创建一本儿童读物，“不合适的望远镜”，该网站和社交媒体流将多样性在科学仪器中的好处作为寓言，以说明种族和文化包容性的益处。拟议项目将研究IO等离子体圆环（ipt）围绕木星围绕木星洞悉Jovian磁性领域的益处。该项目将使用IO输入/输出观测值来对IPT中的S II和NA线进行时间域观测，以确定材料扩散的性质。 IOIO是一个小型机器人冠状动曲，每晚运行现代记录的IPT INS S II的窄带图像。结合IPT模型，观察结果将表明差异是由IO中的质量负载或中间Jovian磁场中的活动驱动的。该项目的儿童读物将表明在少数群体中的价值和具有不同的观点，以及在多数派中的观点，并接受和尊重少数观点。该书将由行星科学研究所屡获殊荣的公共宣传团队制作。该奖项反映了NSF的法定任务，并使用基金会的知识分子优点和更广泛的影响标准，被视为通过评估而被视为珍贵的支持。
